REPRESENTATION Veteran represented by: Disabled American Veterans WITNESS AT HEARING ON APPEAL The Veteran-Appellant ATTORNEY FOR THE BOARD S. Finn, Counsel INTRODUCTION The Veteran served on active duty in the military from May 1968 to October 1970. He received the Purple Heart Medal and Combat Infantryman Badge (CIB). He appealed to the Board of Veterans' Appeals (Board/BVA) from rating decisions of the Department of Veterans Affairs (VA) Regional Office (RO). In an August 1985 decision and remand, the Board remanded the claim of entitlement to service connection for residuals of a SFW of the left elbow. In a February 1987 decision, the Board recharacterized the Veteran's claim more generally as for service connection for residuals of a SFW of the left upper extremity and granted the claim. He filed another claim in January 1998 for service connection for the left elbow disability with shrapnel, alleging additional impairment deserving of compensation. So this claim now concerns whether he is entitled to a compensable rating for the residuals of the SFW of his left upper extremity above the elbow. In an appealed October 1998 rating decision, the RO addressed the issues of entitlement to an increased evaluation for seborrheic dermatitis; entitlement to an increased evaluation for posttraumatic stress disorder (PTSD); entitlement to an increased evaluation for residuals of a SFW of the left ankle with retained metallic fragments; entitlement to an increased evaluation for residuals of a SFW of the left knee with ligament instability; entitlement to an increased evaluation for traumatic arthritis of the left knee; entitlement to an increased evaluation for a retained mortar fragment in the right knee; entitlement to an increased evaluation for left heel scars; entitlement to an increased evaluation for residuals of a liver operation; entitlement to a compensable evaluation for a SFW of the left upper extremity above the elbow; entitlement to service connection for hypertension, including as due to the Veteran's service-connected disabilities; and entitlement to SMC based on the loss of use of both lower extremities or the need for A&A. The October 1998 decision also addressed the issue of entitlement to an initial compensable evaluation for hemorrhoids. See Fenderson v. West, 12 Vet. App. 119, 125-26 (1999) (when a Veteran appeals an initial rating, VA must consider whether to "stage" the rating - meaning assign different ratings at different times since the effective date of the award to compensate him for occasions when the disability has been more severe than at others). A December 1999 rating decision reflects that the left knee with ligament instability and early traumatic arthritis rated as 20-percent disabling was discontinued on February 5, 1998, because it was found to be more properly evaluated under a separate diagnostic code with a 20 percent rating assigned for SFWs with arthritis and an additional 10 percent for limited range of motion. These claims subsequently were the subject of a June 2001 remand for notice to comply with the Veterans Claims Assistance Act (VCAA) that recently had been signed into law. A July 2001 rating decision granted the Veteran's claim for service connection for Hepatitis C and assigned an initial 10 percent rating retroactively effective from February 5, 1998. He appealed for a higher initial rating. See again Fenderson, 12 Vet. App. at 125-26. And in a February 2002 rating decision since issued, the RO increased the rating to 60 percent with the same retroactive effective date of February 5, 1998. He since has continued to appeal, requesting an even higher initial rating for this disability. See AB v. Brown, 6 Vet. App. 35, 38-39 (1993) (It is presumed a Veteran is seeking the highest possible rating for a disability, absent express indication to the contrary). The February 2002 rating decision denied his claim for an increased evaluation for the residuals of the laparotomy scar. In a March 2003 decision, the Board granted his claim of entitlement to a higher rating for the DJD of his lumbosacral spine - increasing the rating for this disability to 40 percent retroactively effective as of September 4, 2001. However, the Board denied the claims for higher ratings for the residuals of the SFW of his right lung with retained fragments and for the residual scars on his left foot, as well as for service connection for a neck disorder, tendonitis of the elbows, and carpal tunnel syndrome of the wrists. He submitted a Notice of Disagreement (NOD) with that decision in April 2003, so the following month. As such, in March 2005 the Board remanded these claims to the RO via the Appeals Management Center (AMC) to send him a Statement of the Case (SOC) addressing these particular claims, as indicated as the appropriate disposition in Manlincon v. West, 12 Vet. App. 238 (1999). And after the AMC issued an SOC in June 2005 addressing these additional claims, he subsequently perfected his appeal of these additional claims to the Board by filing a timely substantive appeal (VA Form 9) in response. See 38 U.S.C.A. § 7105(a) (West 2002); 38 C.F.R. § 20.200 (2012). Another reason for that March 2005 remand was to schedule a hearing at the RO before a Veterans Law Judge of the Board (Travel Board hearing). And the Veteran had this hearing in October 2010. In a May 2008 rating decision, the AMC increased the rating for the Veteran's PTSD from 30 to 70 percent retroactively effective from November 7, 1997, the date service connection was established. In a March 2011 decision, the Board found that from November 7, 1997 to June 18, 2006, the criteria were not met for a rating higher than 70 percent for the PTSD. Since June 19, 2006, however, the criteria had been met for a 100 percent rating for the PTSD, so for the highest possible schedular rating. In an April 2011 rating decision, the RO implemented the Board's decision and assigned the higher 100 percent disability rating retroactively effective from June 19, 2006. In response the Veteran appealed for an earlier effective date for this higher rating (see his April 2011 NOD). See also Grantham v. Brown, 114 F.3d 1156, 1158-59 (Fed. Cir. 1997) (indicating he had to separately appeal this "downstream" issue). But this issue already had been addressed by the Board in its March 2011 decision since, from November 7, 1997 to June 18, 2006, the Board had determined that the criteria were not met for a rating higher than 70 percent for the PTSD. In April 2011, the RO advised him of the process by which he could appeal or seek reconsideration of the Board's decision. He did not, however, file a request for reconsideration of that decision or appeal to the higher U. S. Court of Appeals for Veterans Claims (Court/CAVC). He did nonetheless perfect an appeal of another claim to the Board, namely, for osteoarthritis of his hands, by filing a timely substantive appeal (e.g., VA Form 9 or equivalent statement) in response to the December 2007 SOC. See again 38 U.S.C.A. § 7105 (West 2002); 38 C.F.R. § 20.200 (2012). But a September 2012 rating decision granted service connection for psoriatic arthritis of his hands (claimed as osteoarthritis of his hands), assigning a 10 percent rating retroactively effective from April 28, 2005. And since he did not separately appeal either this rating or effective date, this claim is no longer at issue. Grantham v. Brown, 114 F.3d 1156, 1158-59 (Fed. Cir. 1997) (where an appealed claim for service connection is granted during the pendency of the appeal, a second NOD thereafter must be timely filed to initiate appellate review of the claim concerning "downstream" issues such as the compensation level assigned for the disability and effective date). Also in the March 2011 decision, the Board denied the claim for service connection for hypertension, neck/cervical spine disorder, and bilateral carpal tunnel syndrome. The Veteran's remaining claims instead were remanded for further development, including especially to obtain outstanding VA treatment records and to have him undergo VA compensation examinations. A review of the electronic ("Virtual VA") paperless claims file does not reflect additional treatment records other than those cited in the Board's remand. Instead of paper, a highly secured electronic repository is now being used more and more to store and review every document involved in the claims process. Indeed, VA is in the process of transitioning to an even newer and purportedly better system - the Veterans Benefits Management System (VBMS). The use of Virtual VA and the VBMS allows VA to leverage information technology in order to more quickly and accurately decide claims for benefits. Because this appeal was processed as part of the Virtual VA system, any future consideration of the Veteran's claims should take into consideration the existence of this electronic record. In November 2008 the Veteran alleged clear and unmistakable error (CUE) in the November 18, 1970 rating decision regarding his initial rating for the residuals of the SFW of his right lung with retained fragments. (See November 2008 Written Statement). He essentially asserts that he was entitled to a higher rating for this disability because DCs 6818-5321 were two different diagnostic codes that require separation for a higher evaluation, either as an individual disability or to be used in a bilateral factor. (See November 2012 Post-Remand Brief). The Board is referring this claim to the RO, as the Agency of Original Jurisdiction (AOJ), for initial consideration. The Board generally does not have jurisdiction to consider claims that have not been considered by the RO in the first instance, as this in effect would deprive the Veteran of the initial level of review such that he would lose the proverbial "one bite at the apple." The Veterans Court (CAVC) has clarified the meaning of the terms frequently used to determine the scope of a claim properly on appeal before the Board. See Hillyard v. Shinseki, 24 Vet. App. 343, 355 (2011). A "claim" seeks entitlement to a benefit, a "theory" is a means of establishing entitlement to the benefit sought, and a "matter" is the entire subject under consideration. Id. All theories pertaining to the same benefit for the same disability are part of the same claim. Id.; but see Jarrell v. Nicholson, 20 Vet. App. 326, 332 (2006) (distinguishing requests for revision of a decision on the grounds of CUE under 38 U.S.C.A. § 5109(a) (West 2002)). As the meaning of the term encompasses the entire subject under consideration by the adjudicatory body, the scope of the matter may be different at different stages of adjudication. Hillyard, 24 Vet. App. at 355. Accordingly, the Board has jurisdiction to adjudicate the merits of different theories, or questions, on a single matter because the Veteran's appeal properly brings all means of establishing entitlement to the benefit sought before the Board. Godfrey v. Brown, 7 Vet. App. 398, 409 (1995); see also Hillyard, 24 Vet. App. at 355. However, an NOD and Substantive Appeal (VA Form 9 or equivalent statement) filed by the Veteran cannot confer jurisdiction on the Board to review claims that are wholly separate and distinct from the claim presented to and adjudicated by the RO. Jarrell, 20 Vet. App. at 332; Godfrey, 7 Vet. App. at 409. The claim of entitlement to service connection for a right elbow disorder (claimed as tendonitis), including as secondary to the service-connected seborrheic dermatitis, also the claims for higher ratings for the seborrheic dermatitis, for residuals of a SFW of the left ankle with retained fragments, for residuals of a SFW of the left knee with ligament instability, for residuals of a SFW of the right knee with retained fragments, for residuals of a SFW of the left upper extremity above the elbow, for residuals of a SFW of the right lung with retained fragments, and for SMC based on the loss of use of both lower extremities or the need for A&A all require further development before being decided on appeal. So the Board is remanding these claims to the RO via the AMC. Whereas the Board, instead, is going ahead and deciding the remaining claims. FINDINGS OF FACT 1. The Veteran has severe, rather than pronounced, intervertebral disc syndrome (IVDS) of his lumbar spine, which is manifested by complaints of increasing pain and consequent limitation of forward flexion to between 10 and 25 degrees. He does not have unfavorable ankylosis of his entire thoracolumbar spine, however, and has not experienced incapacitating episodes having a total duration of at least 6 weeks during the past 12 months. 2. He has at least 5 total post-surgical scars that are painful and unstable. 3. His left knee has mild-to-moderate osteoarthritis that causes painful motion with flexion, at worst, limited to 80 degrees but with full extension to 0 degrees. 4. His right knee has mild osteoarthritis and painful motion with flexion, at worst, limited to 94 degrees but with full extension to 0 degrees. 5. The residuals of the laceration of his liver include a pulling sensation in his back, a painful abdominal area, and palpable adhesions. 6. The preponderance of the evidence weighs against finding that his Hepatitis C causes near-constant debilitating symptoms. 7. He does not have external or internal hemorrhoids that are large or thrombotic, irreducible, with excessive redundant tissue, evidencing frequent recurrences. CONCLUSIONS OF LAW 1. The criteria are not met for a rating higher than 40 percent for the DJD of the lumbar spine. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 3.321(b)(1), 4.3, 4.7, 4.40, 4.45, 4.59 (2012); 38 C.F.R. § 4.71a, Diagnostic Code 5293 (2002), as amended by 67 Fed. Reg. 54,345 (Aug. 22, 2002) and 68 Fed. Reg. 51,454 (Aug. 27, 2003), now codified at 38 C.F.R. § 4.71a, Diagnostic Codes 5235-5243. 2. The criteria are not met for a rating higher than 10 percent for the painful scars of the left foot, left heel, and laparotomy from February 5, 1998 to October 22, 2008. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 3.321, 3.400, 4.1, 4.2, 4.3, 4.7, 4.10 (2012); 4.118, Diagnostic Code 7804 (prior to October 23, 2008). 3. But the criteria are met for a higher 40 percent rating, though no greater rating, for these scars (left foot, left heel, and laparotomy) since October 23, 2008. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 3.321, 3.400, 4.1, 4.2, 4.3, 4.7, 4.10 (2012); 4.118, Diagnostic Code 7804 (from October 23, 2008). 4. The criteria are not met for a rating higher than 10 percent for the osteoarthritis and painful motion of the left knee. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. §§ 4.3, 4.7, 4.10, 4.40, 4.45, 4.59, 4.71a, Diagnostic Codes (DCs) 5003, 5010, 5260, 5261 (2012). 5. The criteria are met, however, for a separate 10 percent rating for the osteoarthritis of the right knee and painful motion. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 3.321, 4.1, 4.3, 4.7, 4.40, 4.45, 4.59, 4.71a, DCs 5003, 5010, 5260, 5261 (2012). 6. But the criteria are not met for a rating higher than 10 percent for the post-operative liver laceration residuals. U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. § 4.114, DC 7301-7311 (2001), effective prior to July 2, 2001; 38 C.F.R. §§ 3.102, 3.159, 4.112, 4.114, DC 7345 (2004), effective July 2, 2001. 7. The criteria also are not met for a rating higher than 60 percent for the Hepatitis C. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. §§ 4.1, 4.2, 4.3, 4.7, 4.114, DC 7354 (2012). 8. The criteria are not met, as well, for a compensable rating for the hemorrhoids. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. § 4.97, DC 7336 (2012). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS The Duties to Notify and Assist The VCAA describes VA's duties to notify and assist a claimant in substantiating a claim for VA benefits upon receipt of a complete or substantially complete application. 38 U.S.C.A. §§ 5100, 5102, 5103, 5103A, 5107, 5126; 38 C.F.R. §§ 3.102, 3.156(a), 3.159, 3.326(a). VCAA notice consistent with 38 U.S.C.A. § 5103(a) and 38 C.F.R. § 3.159(b) must: (1) inform the claimant of the information and evidence not of record that is necessary to substantiate the claim; (2) inform him of the information and evidence that VA will obtain; and (3) inform him of the information and evidence that he is expected to provide. See also Quartuccio v. Principi, 16 Vet. App. 183, 187 (2002). It is important to keep in mind, however, that some of these claims (specifically, those regarding the Hepatitis C, postoperative liver laceration, hemorrhoids, and DJD of the lumbar spine) arose in the context of the Veteran trying to establish his underlying entitlement to service connection for these disabilities. So any VCAA notice initially provided would have addressed these claims in this specific context. Service connection for these disabilities since has been granted in the decisions precipitating this appeal. And the U. S. Court of Appeals for the Federal Circuit (Federal Circuit Court) has held that, once service connection is granted, the claim, as it arose in its initial context has been substantiated, indeed proven, so the initial intended purpose of the notice served such that § 5103(a) notice is no longer required. Hartman v. Nicholson, 483 F.3d 1311 (Fed. Cir. 2007); Sutton v. Nicholson, 20 Vet. App. 419 (2006). In this situation, then, VA is not required to provide additional VCAA notice concerning the "downstream" disability rating and effective date elements of the claim. Goodwin v. Peake, 22 Vet. App. 128 (2008). See also Dunlap v. Nicholson, 21 Vet. App. 112 (2007) and VAOPGCPREC 8-2003, 69 Fed. Reg. 25180 (May 5, 2004). Rather, according to the holding in Goodwin and these other precedent cases and VA General Counsel's Opinion, instead of issuing an additional VCAA notice letter in this situation concerning the "downstream" disability rating element of the claim, the provisions of 38 U.S.C.A. § 7105(d) require VA to issue an SOC if the disagreement is not resolved. The RO sent the Veteran this required SOC addressing the "downstream" disability rating element of his claims. The RO/AMC also since has provided him supplemental SOCs (SSOCs). The SOC and SSOCs included citation to the applicable statutes and regulations governing the assignment of disability ratings, including initial ratings, and contained discussions of the reasons and bases for not assigning higher initial ratings for these disabilities. He therefore has received all required notice concerning his "downstream" claims for higher initial ratings for these disabilities. He nonetheless was provided letters in May 2002, June 2005, December 2007, July 2008 and March 2011 indicating the types of evidence necessary to substantiate these initial-rating claims for his Hepatitis C, hemorrhoids, and DJD of the lumbar spine, also concerning his increased rating claims for his scars, left knee, and right knee disabilities, and explaining the division of responsibility between him and VA in obtaining this supporting evidence, including the information needed to obtain both his private and VA medical treatment records. The letter also explained how a "downstream" disability rating and effective date are determined once, as here, service connection for the claimed disability is granted, in compliance with Dingess/Hartman v. Nicholson, 19 Vet. App. 473, 490-491 (2006), aff'd sub nom. Hartman v. Nicholson, 483 F.3d 1311 (2007). With regard to his increased rating claims (for his scars, left knee, and right knee), the Veterans Court initially held in Vazquez-Flores v. Peake, 22 Vet. App. 37, 48 (2008), that, for an increased-compensation claim (so including a claim for SMC), 38 U.S.C. § 5103(a) requires, at a minimum, that VA notify the claimant that, to substantiate the claim, the medical or lay evidence must show a worsening or increase in severity of the disability, and the effect that such worsening or increase has on the claimant's employment and daily life. On appeal, however, in Vazquez- Flores v. Shinseki, 580 F.3d 1270, 1277 (2009), the Federal Circuit Court vacated and remanded important aspects of the Court's holding in Vazquez-Flores, as well as a related case, Schultz v. Peake, No. 03-1235, 2008 WL 2129773, at 5 (Vet. App. Mar. 7, 2008). Significantly, the Federal Circuit Court concluded that "the notice described in 38 U.S.C. § 5103(a) need not be Veteran specific." Similarly, "while a Veteran's 'daily life' evidence might in some cases lead to evidence of impairment in earning capacity, the statutory scheme does not require such evidence for proper claim adjudication." Thus, the Federal Circuit Court held, "insofar as the notice described by the [Court] in Vazquez- Flores requires the VA to notify a Veteran of alternative diagnostic codes or potential "daily life" evidence, we vacate the judgments." Vazquez, 580 F.3d at 1277. It also since has been held in Vazquez-Flores v. Shinseki, No. 05-0355, 2010 WL 4146124 (Vet. App. Oct. 22, 2010), that after a notice error, such as failing to inform the Appellant to submit evidence demonstrating the effect that a worsening of the disability has on employment, is found in an increased-rating claim, the Appellant's burden to demonstrate prejudice at the CAVC level does not shift to VA unless notice is not provided at all. In Shinseki v. Sanders, 129 S. Ct. 1696 (2009), the U.S. Supreme Court made clear that a reviewing court, in considering the rule of prejudicial error, is precluded from applying a mandatory presumption of prejudice rather than assessing whether, based on the facts of each individual case, the error was outcome determinative. In Sanders, the Supreme Court rejected the lower Federal Circuit Court's framework (see Sanders v. Nicholson, 487 F.3d 881, 889 (Fed. Cir. 2007)) that all VA notice errors are presumptively prejudicial, in part, because it was "complex, rigid, and mandatory." Id. at 1704. The Supreme Court rejected the Federal Circuit Court's analysis because it imposed an unreasonable evidentiary burden on VA to rebut the presumption and because it required VA to demonstrate why the error was harmless, rather than requiring the appellant - as the pleading party - to show the error was harmful. Id. at 1704-05. The Supreme Court stated that it had "warned against courts' determining whether an error is harmless through the use of mandatory presumptions and rigid rules rather than case-specific application of judgment, based upon examination of the record." Id. at 1704-05. Thus, it is clear from the Supreme Court's analysis that, while a Court may conclude generally that a specific type of error is more likely to prejudice an appellant, the error nonetheless must be examined in the context of the facts of the particular case. Id. Moreover, as the pleading party attacking the agency's decision, the Veteran, not VA, has this burden of proof. VA's additional duty to assist under the VCAA includes helping the claimant to obtain potentially relevant records, including service treatment records (STRs) and other pertinent records of evaluation and treatment since service, as well as providing an examination or obtaining a medical opinion when needed to make a decision on the claim. See 38 U.S.C.A. § 5103A; 38 C.F.R. § 3.159(c). There are not these obligations if there is no reasonable possibility that assisting the Veteran with his claim would result in substantiation of it. To this end, the Veteran was provided VA compensation examinations in August 1998, August 2001, May 2002, July 2006, and August 2011. These examinations were comprehensive and adequate for the purposes of deciding these claims. The reports reflect that the examiners reviewed his medical history, recorded his then current complaints, performed an appropriate objective physical examination, and rendered appropriate diagnoses and opinions consistent with the other relevant evidence of record, both initially in terms of etiologies (when the issue was entitlement to service connection) and then subsequently regarding the severity of these disabilities (owing to the fact that this now is the more determinative "downstream" issue). In Monzingo v Shinseki, 26 Vet. App. 97, 107 (2012), the Court held that "examination reports are adequate when, as a whole, they sufficiently inform the Board of a medical expert's judgment on a medical question and the essential rationale for that opinion" even when the rationale does not explicitly "lay out the examiner's journey from the facts to a conclusion." Citing Acevedo v. Shinseki, 25 Vet. App. 286, 293 (2012) (noting that the law imposes no reasons-or- bases requirement on examiners); see also D'Aries v. Peake, 22 Vet. App. 97, 104 (2008) (holding that an examination is adequate when it is based on consideration of the claimant's medical history and describes the disability in sufficient detail so that the Board's evaluation of the disability will be a fully informed one). Neither the Veteran nor his representative has raised questions about the adequacy of those examinations. Unless the claimant challenges the adequacy of an examination or opinion, the Board may assume that the examination report and opinion are adequate and need not affirmatively establish the adequacy of the examination report or the competence of the examiner. Sickels v. Shinseki, 643 F.3d, 1362, 1365-66 (Fed. Cir. 2011) (holding that although the Board is required to consider issues independently raised by the evidence of record, the Board is still "entitled to assume" the competency of a VA examiner and the adequacy of a VA opinion without "demonstrating why the medical examiners' reports were competent and sufficiently informed"); see also Rizzo v. Shinseki, 580 F.3d 1288, 1290- 1291 (Fed. Cir. 2009) (holding that the Board is entitled to assume the competency of a VA examiner unless the competence is challenged). But even when this is challenged, the Board may assume the competency of any VA medical examiner as long as, under 38 C.F.R. § 3.159(a)(1), the examiner is qualified through education, training, or experience to offer medical diagnoses, statements, or opinions. See Cox v. Nicholson, 20 Vet. App. 563 (2007). The Veteran also testified at a hearing before the Board in October 2010 that essentially focused on the elements necessary to substantiate his claims. His hearing testimony and his representative's statements and testimony demonstrate their actual knowledge of the elements necessary to substantiate the claims. See Dalton v. Nicholson, 21 Vet. App. 23, 30-31 (2007) (actual knowledge is established by statements or actions by the claimant or the claimant's representative demonstrating an awareness of what is necessary to substantiate a claim). As such, the Board finds that, consistent with Bryant v. Shinseki, 23 Vet. App. 488 (2010), the presiding Veterans Law Judge (VLJ) of the Board complied with the duties set forth in 38 C.F.R. 3.103(c)(2) (2012) in terms of: (1) explaining fully the issues and (2) suggesting the submission of evidence that the claimant may have overlooked and that would be advantageous to his position. Further, the RO and AMC complied with the prior remand directives in June 2001, March 2005, and March 2011 by providing the Veteran a hearing; obtaining all VA and non-VA treatment records, Social Security Administration (SSA) records, STRs, lay testimony and statements offered in support of the claims, and by having him examined and reexamined to assess and reassess the severity of his disabilities. See Stegall v. West, 11 Vet. App. 268, 271 (1998) (holding that a remand by the Board confers upon the Veteran, as a matter of law, the right to compliance with its remand instructions, and imposes upon VA a concomitant duty to ensure compliance with the terms of the remand); but see also D'Aries v. Peake, 22 Vet. App. 97, 105 (2008) (holding that only substantial rather than strict compliance with the Board's remand directives is required under Stegall); accord Dyment v. West, 13 Vet. App. 141, 146-47 (1999). All relevant evidence necessary for an equitable resolution of these claims has been identified and obtained, to the extent possible. The evidence of record includes as mentioned the STRs, SSA records, private records, VA medical records, VA examination reports, and statements from the Veteran and his representative. They have not indicated they have any further evidence to submit to VA or that VA needs to obtain. There is no indication there exists any additional evidence that has a bearing on these claims being decided that has not been obtained. The Veteran has been accorded ample opportunity to present evidence and argument in support of these claims. All pertinent due process requirements have been met. Higher Rating Claims - In General Disability ratings are assigned in accordance with VA's Schedule for Rating Disabilities and are intended to represent the average impairment of earning capacity resulting from disability. See 38 U.S.C.A. § 1155; 38 C.F.R. §§ 3.321(a), 4.1. Separate diagnostic codes identify the various disabilities. 38 C.F.R, Part 4. The Court has held that an appeal from an initial rating is a separate and distinct claim from a claim for an increased rating. See Fenderson v. West, 12 Vet App 119 (1999). Therefore, in matters concerning an initial rating, separate ratings can be assigned for separate periods of time based on facts found, a practice known as "staged" ratings. See Fenderson, 12 Vet. App. 125-26. The Court since has extended this practice even to cases that do not involve initial ratings, so also established ratings. Hart v. Mansfield, 21 Vet. App. 505 (2007). When entitlement to compensation already has been established, and an increase in the disability rating is at issue, the present level of disability is the primary concern. Although a rating specialist is directed to review the recorded history of a disability to make a more accurate evaluation, the regulations do not give past medical reports precedence over current findings. See Francisco v. Brown, 7 Vet. App. 55 (1994); 38 C.F.R. § 4.2. VA regulations require that disability evaluations be based upon the most complete evaluation of the condition that can be constructed with interpretation of examination reports, in light of the whole history, so as to reflect all elements of the disability. Medical as well as industrial history is to be considered, and a full description of the effects of the disability upon ordinary activity is also required. Functional impairment is based on lack of usefulness and may be due to pain, supported by adequate pathology and evidenced by visible behavior during motion. Many factors are to be considered in evaluating disabilities of the musculoskeletal system and these include pain, weakness, limitation of motion, and atrophy. Painful motion with the joint or periarticular pathology, which produces disability, warrants the minimum compensation. 38 C.F.R. §§ 4.1, 4.2, 4.10, 4.40, 4.45, 4.59; DeLuca v. Brown, 8 Vet. App. 202 (1995). The provisions of 38 C.F.R. § 4.14 (avoidance of pyramiding) does not forbid consideration of a higher rating based on greater limitation of motion due to pain on use, including prolonged use or during flare-ups. Functional loss due to pain is rated at the same level as functional loss where motion is impeded. Schafrath, 1 Vet. App. at 592. Pursuant to 38 C.F.R. § 4.59, painful motion should be considered limited motion, even though a range of motion may be possible beyond the point when pain sets in. See Powell v. West, 13 Vet. App. 31, 34 (1999); Hicks v. Brown, 8 Vet. App. 417, 421 (1995). See also Burton v. Shinseki, 25 Vet. App. 1 (2011) (holding that application of 38 C.F.R. 4.59 is not just limited to cases where there is arthritis). But that said, although pain may cause functional loss, pain itself does not constitute functional loss. See Mitchell v. Shinseki, 25 Vet. App. 32, 38-43 (2011). Rather, pain must affect some aspect of "the normal working movements of the body" such as "excursion, strength, speed, coordination, and endurance," in order to constitute functional loss. Id.; see 38 C.F.R. § 4.40. Also, a finding of functional loss due to pain must be supported by adequate pathology and evidenced by the visible behavior of the Veteran. 38 C.F.R. § 4.40. Moreover, if a Veteran is already receiving the maximum disability rating available based on symptomatology that includes limitation of motion, it is not necessary to consider whether 38 C.F.R. §§ 4.40 and 4.45 are applicable. Johnston v. Brown, 10 Vet. App. 80, 85 (1997). Where there is a question as to which of two evaluations shall be applied, the higher evaluation will be assigned if the disability picture more nearly approximates the criteria for the higher rating; otherwise, the lower rating will be assigned. 38 C.F.R. § 4.7. All reasonable doubt material to the determination is resolved in the Veteran's favor. 38 C.F.R. § 4.3. Low Back Disability During the pendency of this appeal, regulatory changes amended the VA Schedule for Rating Disabilities, 38 C.F.R. Part 4, including the criteria for rating disabilities of the spine. Effective September 23, 2002, VA revised the criteria for rating IVDS, so after the filing of this claim at hand in June 1994. 67 Fed. Reg. 54,345 (Aug. 22, 2002). Effective September 26, 2003, VA again revised the criteria for rating general diseases and injuries of the spine. 68 Fed. Reg. 51,454 (Aug. 27, 2003). Disabilities and injuries of the spine are currently evaluated under 38 C.F.R. § 4.71a, Diagnostic Codes 5235 through 5243. The revised provisions of Diagnostic Code 5293 were redesignated as Diagnostic Code 5243 for IVDS, effective September 26, 2003. The Board is required to consider the claim in light of both the former and revised schedular criteria to determine whether a higher rating is warranted for the lumbar spine disability. VA's General Counsel has determined however that the amended rating criteria, if more favorable to the claim, only may be applied prospectively, so only for the periods from and after the effective date of the regulatory changes. However, the Veteran gets the benefit of having both the former and revised regulations considered for the period after the change was made. See VAOPGCPREC 3-2000 (Apr. 10, 2000). See also Kuzma v. Principi, 341 F.3d 1327 (Fed. Cir. 2003); VAOPGCPREC 7-2003 (Nov. 19, 2003). This guidance is consistent with longstanding statutory law, to the effect that an increase in benefits cannot be awarded earlier than the effective date of the change in law pursuant to which the award is made. See 38 U.S.C.A. § 5110(g). See also 38 C.F.R. § 3.114. Under Diagnostic Code 5292, in effect prior to September 26, 2003, a 20 percent rating requires moderate limitation of lumbar spine motion. A maximum 40 percent rating requires severe limitation of lumbar spine motion. Under Diagnostic Code 5295, in effect prior to September 26, 2003, a 20 percent rating was assigned for disability manifested by muscle spasm on extreme forward bending and loss of lateral motion, unilateral, in a standing position. A 40 percent evaluation was assigned for severe disability manifested by listing of the whole spine to the opposite side, a positive Goldthwaite's sign, marked limitation of forward bending in a standing position, loss of lateral motion with osteoarthritis changes, or narrowing or irregularity of joint space. A 40 percent was also assigned if only some of these manifestations were present with abnormal mobility of forced motion. A 40 percent rating is the highest schedular evaluation assignable under the former Diagnostic Code 5295. Under Diagnostic Code 5293, in effect prior to September 23, 2002, a 20 percent rating was assigned for IVDS if involving moderate, recurring attacks. A 40 percent rating was assigned for severe IVDS manifested by recurring attacks with intermittent relief. And a 60 percent rating was assigned for pronounced IVDS involving persistent symptoms compatible with sciatic neuropathy with characteristic pain and demonstrable muscle spasm, absent ankle jerk, or other neurological findings appropriate to the site of the diseased disc with attack with little intermittent relief. Under the revised criteria, effective from September 23, 2002, IVDS is evaluated either on the total duration of incapacitating episodes over the past 12 months or by combining under 38 C.F.R. § 4.25 separate evaluations of its chronic orthopedic and neurologic manifestations along with evaluations for all other disabilities, whichever method results in the higher evaluation. See 38 C.F.R. § 4.71a, Diagnostic Code 5293, as amended by 67 Fed. Reg. 54345-54349 (Aug. 22, 2002). A 20 percent evaluation is assigned with incapacitating episodes of having a total duration of at least two weeks but less than four weeks during the past 12 months. A 40 percent evaluation is assigned with incapacitating episodes of having at total duration of at least four weeks but less than six weeks during the past 12 months. A 60 percent evaluation is assigned with incapacitating episodes of having a total duration of at least six weeks during the past 12 months. Id.; see also 38 C.F.R. § 4.71a, The Spine, Formula for Rating IVDS based on Incapacitating Episodes (same effect). Note (1): For purposes of evaluations under 5293, an incapacitating episodes is a period of acute signs and symptoms due to IVDS that requires bed rest prescribed by a physician and treatment by a physician. "Chronic orthopedic and neurologic manifestations" mean orthopedic and neurologic signs and symptoms resulting from IVDS that are present constantly, or nearly so. Compare, 67 Fed. Reg. 54345 (Aug. 22, 2002), effective September 23, 2002, and codified at 38 C.F.R. § 4.71a, Diagnostic Code 5293 (2003); 68 Fed. Reg. 51454 (Aug. 27, 2003), effective September 26, 2003, [Diagnostic Code 5293 redesignated as 5243 and codified at 38 C.F.R. § 4,71a, The Spine, Formula for Rating IVDS based on Incapacitating Episode, Note (1) (same effect)]. Note (2): When evaluating on the basis of chronic manifestations, evaluate orthopedic disabilities using evaluation criteria for the most appropriate orthopedic diagnostic code or codes. Evaluate neurologic disabilities separately using evaluation criteria for the most appropriate neurologic code or codes. Note (3): If IVDS is presented in more than one spinal segment, provided that the effects in each spinal segment are clearly distinct, evaluate each segment on the basis of chronic orthopedic and neurologic manifestations or incapacitating episodes, whichever method results in a higher evaluation for that segment. Under the revised criteria, effective from September 26, 2003, disabilities of the spine will be evaluated under the General Rating Formula for Diseases and Injuries of the Spine or under the Formula for Rating IVDS based on Incapacitating Episodes, whichever method results in the higher evaluation when all disabilities are combined under § 4.25. 38 C.F.R. § 4.71a, The Spine, General Rating Formula for Diseases and Injuries of the Spine, Note (6). Under the General Rating Formula for Diseases and Injuries of the Spine, the following evaluations are assignable with or without symptoms such as pain (whether or not it radiates), stiffness, or aching in the area of the spine affected by residuals of injury or disease: A 20 percent rating is warranted when forward flexion of the thoracolumbar spine is greater than 30 degrees, but not greater than 60 degrees, or the combined range of motion of the thoracolumbar spine is not greater than 120 degrees; or there is muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis. A 40 percent rating is warranted when forward flexion of the thoracolumbar spine is 30 degrees or less; or there is favorable ankylosis of the entire thoracolumbar spine. A 50 percent rating is warranted if there is unfavorable ankylosis of the entire thoracolumbar spine. A 100 percent rating is warranted if there is unfavorable ankylosis of the entire spine (that is, when also considering the adjacent cervical segment). See 38 C.F.R. § 4.71a, The Spine, General Rating Formula for Diseases and Injuries of the Spine, Diagnostic Codes 5235 to 5242. For VA compensation purposes, normal forward flexion of the thoracolumbar spine is from zero to 90 degrees; backward extension is zero to 30 degrees; left and right lateral flexion are zero to 30 degrees; and left and right lateral rotation are zero to 30 degrees. The combined range of motion refers to the sum of the range of forward flexion, extension, left and right lateral flexion, and left and right rotation. The combined normal range of motion of the thoracolumbar spine is 240 degrees. The normal ranges of motion for each component of the spinal motion provided in this note are the maximum that can be used for calculation of the combined range of motion. 38 C.F.R. § 4.71a, The Spine, General Rating Formula for Diseases and Injuries of the Spine, Note (2) (See also Plate V). A December 1998 x-ray of the spine showed minor focal degenerative disease at the L5-S1 with the lumbar spine otherwise within normal limits. The Veteran was diagnosed with minor degenerative disease of the L5-S1. An April 1999 VA examination reflects back pain, spasms, tenderness, "back locked in flexion," tenderness to the spinatous muscles, pronounced flattening of the lumbar curve. The Veteran was diagnosed with DJD of the lumbosacral spine. A June 2001 spine x-ray reflected moderately severe multi- level disc degeneration. A May 2002 VA examination noted that the Veteran was unable to engage in physical therapy. There was tenderness to palpation over his lumbosacral spine processes and paraspinous region. He was wearing a lumbar support brace and a TENS unit. He was unable to perform the complete examination secondary to discomfort. His gait was markedly antalgic. Forward flexion was to 10 degrees, hyperextension was to 5 degrees, lateral bending was to 5 degrees bilaterally, and rotation was bilaterally to 15 degrees. He was diagnosed with residual arthralgia of the lumbosacral spine. A June 2002 x-ray of the spine was unremarkable. A July 2006 VA examination for DJD of the lumbosacral spine reflects that he did not have any shrapnel injuries to the lower back, but had low back pain since he was in the hospital for an extended period of time recuperating from his lower torso injuries. He was unable to do any bending due to throbbing pain. The Veteran reported no radicular pain to the lower extremities from the back. He had no incapacitating episodes in the last 12 months defined as a period of acute signs and symptoms due to intervertebral disk syndrome. He had lower back pain that was a 10 out of 10 (10 being the worst) all the time. He complained of weakness, stiffness, swelling, heat, redness, instability, locking, fatigue, and lack of endurance. Precipitating factors included turning left or right, bending up and down, light lifting, sneezing, and touching the lower back. Alleviating factors included a back brace, lying down, and pain medications. Upon physical examination, there was a straightening of the lumbar lordosis. There was no over scoliosis. There was tenderness to palpation of the paravertebral musculature of the thoracolumbar spine without spasm. Forward flexion was limited to 20 degrees, extension was -5 degrees, bilateral lateral flexion was 20 degree, and bilateral lateral rotation was to 20 degrees. The Veteran was unable to do repetitive heel stands or walk on his heels. Heel-shin maneuvers could not be done. Heel-to-toe walking could not be done due to instability. He was diagnosed with mild degenerative joint disease of the lumbosacral spine. With regard Deluca, there was a 10 degree loss of forward flexion and 5 degree loss of extension due to pain on repetitive use. There was a mild excess fatigability, weakness, and lack of endurance but no incoordination of the lumbar spine. Pain had a primary functional impact on the Veteran's lumbar spine. An August 2011 VA examination for the thoracolumbar spine reflects that the Veteran was diagnosed with osteoarthritis and degenerative intervertebral disc disease. He stated that "I guess I got something wrong with my disc-something to do with the grenade blast." (See discussion in July 2006 C&P examination). "Since that exam-it has been pretty much the same." After about 3 to 4 hours being up, he needs to lie down for a period of time, but cannot be down too long as it bothers the back. He stated that he could not turn or bend down. The Veteran reported flare-ups, which required him to lie on his back all day. Forward flexion was 20 degrees (normal endpoint is 90) there was objective evidence of painful motion at 5 degrees. Extension was 0 degrees (with normal endpoint is 30) with pain. Right lateral flexion was 10 degrees (normal endpoint is 30). Objective evidence of painful motion was 5 degrees. Left lateral flexion was 10 degrees (normal endpoint is 30). Right lateral rotation was 10 degrees with painful motion at 5 degrees. The left lateral rotation was 15 degrees. There was objective evidence of painful motion at 10 degrees. The Veteran was able to perform repetitive-use testing with 3 repetitions, but had additional limitation in range of motion of the thoracolumbar spine (back) following repetitive-use testing. Post-test forward flexion was 25 degrees; post-extension was 0 degrees; right later flexion was 10 degrees; left lateral flexion 10 degrees; right lateral rotation was 10 degrees; left lateral rotations was 10 degrees. The Veteran had functional loss, functional impairment, and/or additional limitation of range of motion of the thoracolumbar spine after repetitive use. Specifically, he had less movement than normal; pain on movement; atrophy of disuse; interference with listing, standing and/or weight-bearing. The Veteran had localized tenderness to pain to palpation for joint and/or soft tissue of the thoracolumbar spine. He had no guarding or muscle spasm of the thoracolumbar spine. Hip flexion, knee extension, ankle plantar flexion, ankle dorsiflexion, and great toe extension were all 3/5. The Veteran had muscle atrophy-the normal side measured 30.5 cm and the atrophied side measured 27 cm. Sensation to light touch was normal for the anterior thigh, thigh/knee, lower leg/ankle and decreased for the foot/toes. He had positive straight leg raising. He had radicular pain with severe constant pain. There was involvement in to the L2-L5 and S1-S3 nerve root. The Veteran had IVDS with no incapacitating episodes. He used a brace, cane, and powered scooter. The Veteran also had severe cervical DDD and osteoarthritis at L3-L4 and L5- S1. The spine condition impaired his ability to work. This collective body of medical evidence shows the Veteran's low back disability is manifested by severe low back pain, tenderness of his entire back, an unsteady gait requiring the use of a cane and wheelchair, forward flexion ranging from 10 to 25 degrees with observable pain on motion, especially repetitive motion, and premature or excess fatigue, weakness, lack of endurance or incoordination. The maximum rating for limitation of motion of the lumbar spine is 40 percent, assuming there is not ankylosis (which, in effect, as will be explained, means the Veteran cannot have any motion whatsoever), and he already has a 40 percent rating for his low back disability. Where, as here, the Veteran already has the maximum rating assignable for limitation of motion (i.e., 40 percent under the former Diagnostic Code 5292 and now according to DCs 5235-5242 of the General Rating Formula for the Spine), additional consideration of the provisions of DeLuca is not required. See Johnston v. Brown, 10 Vet. App. 80, 85 (1997). Hence, a higher rating is not warranted under either version pertaining to limitation of lumbar spine motion. In order to warrant a rating higher than 40 percent for this low back disability, the evidence must show the Veteran has unfavorable ankylosis of his entire thoracolumbar (thoracic and lumbar) spine, which would permit assigning a 50 percent rating under the General Rating Formula, or unfavorable ankylosis of his entire spine, that is, when additionally considering the adjacent cervical segment, which would permit assigning a 100 percent rating. But he has neither. Ankylosis is stiffening or fixation of the joint as the result of a disease process, with fibrous or bony union across the joint. Dinsay v. Brown, 9 Vet. App. 79, 81 (1996) citing Dorland's Illustrated Medical Dictionary at 94 (31st ed. 2007) (Ankylosis is "immobility and consolidation of a joint due to disease, injury, or surgical procedure."); see also Coyalong v. West, 12 Vet. App. 524, 528 (1999). See, too, Lewis v. Derwinski, 3 Vet. App. 259 (1992) [citing Saunders Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health at 68 (4th ed. 1987)]. Note (5) in 38 C.F.R. § 4.71a, DCs 5235-5242, explains that, for VA compensation purposes, unfavorable ankylosis is a condition in which the entire cervical spine, entire thoracolumbar (thoracic and lumbar) spine, or the entire spine when considering all of these segments together is fixed in flexion or extension. Fixation of a spinal segment in the neutral position (0 degrees) always represents favorable ankylosis (and parenthetically, even if shown, would at most warrant the 40 percent rating the Veteran already has). There is no question he has what amounts to severe limitation of motion of his thoracolumbar spine, especially when considering the effect of his pain in further reducing his range of motion, particularly with prolonged or repetitive movements. But it cannot be said that his spine, either the thoracolumbar segment or entire spine when additionally considering the adjacent cervical segment, is fixed in flexion or extension because he retains some measure of range of motion in all directions - forward flexion, backward extension, left and right later flexion (side bending), and left and right rotation (twisting). By definition, then, his spine is not ankylosed even though he states that his back is "locked in flexion" and he could not "turn or bend down." (See April 1999 VA examination and August 2011 VA examination). There equally is not evidence of any episodes of incapacitation, meaning where bed rest was prescribed by a physician. See Note (1) in DC 5243. The mere fact that the Veteran has elected or felt the need to stay in bed and rest his low back at times in years past is not equivalent or even tantamount to concluding he has experienced an incapacitating episode according to the specific definition in this VA regulation, much less of the frequency and duration required to warrant a rating higher than 40 percent under this DC. In fact, the July 2006 VA examiner stated the Veteran had no incapacitating episodes in the last 12 months defined as a period of acute signs and symptoms due to IVDS. He also does not have "prounounced" IVDS that would warrant a 60 percent rating under the former criteria, which require consideration of neurological symptoms appropriate to the site of the diseased disc and, in effect, consider the associated neurological impairment (radiculopathy/sciatica) in the rating for the low back disability itself. During a July 2006 VA examination, the Veteran reported no radicular pain to his lower extremities from his back. Although during his August 2011 VA examination he complained of radicular pain, he was not diagnosed with radiculopathy or sciatica. Although lay persons are competent to provide opinions on some medical issues, see Kahana v. Shinseki, 24 Vet. App. 428, 435 (2011), as to the specific issue in this case, the severity of a spine disability as defined by current and revised regulations, this falls outside the realm of common knowledge of a lay person. See Jandreau v. Nicholson, 492 F.3d 1372, 1377 n.4 (Fed. Cir. 2007) (lay persons not competent to diagnose cancer). The criteria are not met for an initial rating higher than 40 percent for the DDD of the lumbar spine. And this has been the case since the filing of this claim, so the Board cannot "stage" this rating either under Fenderson. In making this rating determination, the Board has considered the potential applicability of the benefit-of- the-doubt doctrine, but the preponderance of the evidence is against assignment of any higher rating, so this doctrine has no application to the facts of this particular case. See 38 U.S.C.A. § 5107(b); 38 C.F.R. § 4.3; Gilbert v. Derwinski, 1 Vet. App. 49, 53-56 (1990). Scars from the SFWs and Laparotmy The Veteran has a 10 percent rating for a residual scar on his left thigh effective from August 9, 1982; 10 percent rating for a laparotomy scar effective from August 23, 1984; residual scars on his left heel rated as 10-percent disabling effectively since August 9, 1982; a 10 percent rating for residual scars on his left foot effectively since August 9, 1982; and SFW residual scars on his back, right foot, left knee, and left ankle rated as noncompensable effectively since October 17, 1970. At the time he filed his claim in January 1998, Diagnostic Code 7804 provided a maximum 10 percent rating for scars that were superficial but tender and painful on objective demonstration. 38 C.F.R. § 4.118, DC 7804. While this appeal was pending, the applicable rating criteria (Diagnostic Code 7804) for scars were twice revised. Prior to August 30, 2002, the applicable rating criteria were: Scars that are superficial, tender and painful on objective demonstration may be rated at a maximum rating of 10 percent disabling. 38 C.F.R. § 4.118, Diagnostic Code 7804 (2002). The Note for DC 7804 stated that: "[t]he 10 percent rating will be assigned, when the requirements are met, even though the location may be on tip of finger or toe, and the rating may exceed the amputation value for the limited involvement." Diagnostic Code 7802 for scars, burns, second degree provides a 10 percent rating for area or areas approximating 1 square foot (0.1 m squared). The Note states: "See Note (2) under diagnostic code 7801." Note (2) under DC 7801 states: "Ratings for widely separated areas, as on two or more extremities or on anterior and posterior surfaces of extremities or trunk, will be separately rated and combined. Effective August 30, 2002, the rating criteria became as follows: Scars that are superficial and painful on examination may be rated at a maximum rating of 10 percent disabling. 38 C.F.R. § 4.118, Diagnostic Code 7804 (2003). A superficial scar was defined as one not associated with underlying soft tissue damage. Effective October 23, 2008, and continuing currently, the rating criteria became as follows: One or two scars that are unstable or painful are rated 10 percent disabling. Three or four scars that are unstable or painful are rated 20 percent disabling. Five or more scars that are unstable or painful are rated a maximum of 30 percent disabling. An unstable scar was defined as one where, for any reason, there is frequent los of covering of skin over the scar. If one or more scars are both unstable and painful, then an additional 10 percent is to be added to the rating based on the number of unstable or painful scars. 38 C.F.R. § 4.118, Diagnostic Code 7804 (2012). Note (2) states that: "If one or more scars are both unstable and painful, add 10 percent to the evaluation that is based on the total number of unstable or painful scars). Note (3) states that: Scars evaluated under diagnostic codes 7800, 7801, 7802, or 7805 may also receive an evaluation under this diagnostic code when applicable. Diagnostic Code 7805 provides that Scars, other (including linear scars) and other effects of scars evaluated under diagnostic codes 7800, 7801, 7802, and 7804: Evaluate and disabling effects(s) not considered in a rating provided under diagnostic codes 7800-7804 under an appropriate diagnostic code. Although the 2008 revision specifies that it applies to claims received after October 23, 2008, and allows for a claimant to ask for review of a scar disability under the new regulations without asserting that disability has increased, the Board does not interpret this language as limiting to the earlier criteria its review of an issue appealed from a pre-October 23, 2008 rating decision. Accordingly, the Board will consider applicable provisions of both the unrevised and revised provisions, although if an award is warranted under the revised provisions the award could only be effective as of the date of the revision. See Kuzma v. Principi, 341 F.3d 1327 (Fed. Cir. 2003) (overruling Karnas v. Derwinski, 1 Vet. App. 308, 312-13 (1991), to the extent it held that, where a law or regulation changes after a claim has been filed or reopened but before the administrative or judicial appeal process has been concluded, the version more favorable to appellant should apply). This scope of review is potentially more favorable to the Veteran than limiting review to the unrevised regulation. Turning now to the facts of this particular case, an April 1969 Narrative Summary, in part, stated that upon physical examination the Veteran had a well-healed abdominal and chest scar with a long leg cast placed on the right for a malaligned fracture of the right tibia and fibula. There was a 3/4 inch by 3/4 inch scar on the right back at the inferior tip of the scapula. He had a 7/5 inch midline laparotomy scar on the abdomen that was not hypertrophic. He had a 1.75 inch by .5 inch scar of the right lateral chest wall. And, a 1.5 by 1.5 inch scar of the right lateral chest wall with a 1.25 by .5 inch scar of the right lateral thigh, 2 inch by .75 inch scar of the right leg laterally above the malleolus. He had two scars on the dorsum of the right foot that were approximately 2 inches by .5 inches, a scar on the posterior left leg. He had a pedicle graft that was 9.5 inches in length, 3.5 inches wide, anteriolateral aspect of the right leg. There was a scar of the left heel lateral 1 by 1.5 inches. He had a split thickness skin graft that was on the left thigh 8 inches wide by 8 inches long. The scar on left calf, which was donor site for the pedicle graft was hypertrophic was severely disfiguring, was approximately one-half square. There was a large scar on the back of the left calf that was tender, and painful on objective demonstration. A May 1970 Physical Evaluation Board Proceedings reflect, in part, that the Veteran had multiple scars that were superficial, tender, and painful of the left calf. In an April 1984 written statement, the Veteran asserts that his laparotomy scar on his stomach was painful and numb to touch. In an undated written statement, the Veteran stated that his scars were tender and painful after walking or standing. A July 2006 VA examination for a left heel scar reflects that it was a dime size lesion with flaky skin. There was no one scar identifiable on the left foot. With regard to residuals of a laparotomy scar, the Veteran had exploratory laparotomy due to shrapnel penetration of the liver. The Veteran believed that there were two pieces left, near the liver. He complained of soreness of the lower laparotomy scar and a numbing pulling sensation of the upper aspect of the scar. The laparotomy scar extended from the xiphoid to about 2 inches below the umbilicus. The inferior aspect of the scar was tender but non-adherent, nondepressed, and non- disfiguring. The Veteran was diagnosed with residual scars of the left heel, foot, and laparotomy scar. He was also diagnosed with extensive scarring of the bilateral lower extremities secondary to multiple surgical procedures and grafts. An August 2011 VA examination reflects that the Veteran had 14 scars. Scar #1 on his chest. There was no skin breakdown or pain. Maximum width was 2 cm and maximum length was 5 cm. The scar was less than 6 square in (39 sq cm). The scar was not painful, there were no signs of skin breakdown, deep, no inflammation, no edema, or no keloid formation. There were no other disabling effects. The Veteran was diagnosed with scar post tube thoracotomy. Scar #2 was located on his trunk. The maximum width was 0.7 cm and maximum length was 5.4 cm. The scar was not painful, there were no signs of breakdown; it was deep, but there was no inflammation, no edema, and no keloid formation. There were no other disabling effects. Scar #3 was located on the trunk the maximum width was 6 cm and length was 17.5 cm. The scar was not painful, there were no signs of skin breakdown; deep no inflammation. no edema, no keloid formation. There were no other disabling effects. Scar #4 was located on the right lower extremity. The maximum width was 2.0 cm and 3.5 cm for length. The area of the scar was less than 6 sq. in. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #5 was located on the right lower extremity. The maximum width was 0.6 cm and 5.5 cm for length. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #6 was located on the right lower extremity. The maximum width was 0.5 cm and 7.5 cm length. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #7 was located on the right lower extremity. The maximum width of the scar was 8 cm and 20 cm for the length. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #8 was located on the right lower extremity. The maximum width of the scar was 0.5 cm and maximum length was 2.0 cm. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #9 was located on the right lower extremity. The maximum width was 2.0 cm and length was 6.5 cm. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #10 was located on the left lower extremity. The maximum width was 1.0 cm and the maximum length was 6.0 cm. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #11 was located on the left lower extremity. The maximum width was 2.0 cm and 3.5 cm. The scar was not painful and there was no skin breakdown, deep, inflammation, edema, or keloid formation. Scar #12 was located on the left lower extremity. The maximum width was 14 cm and length was 33 cm. The scar was not painful; nor were their signs of skin breakdown, inflammation, edema, or keloid formation. Scar #13 was located on the left lower extremity. The maximum width was 1.0 cm and length was 1.0 cm. There was inflammation, edema, and keloid formation. There was also hypergranulation/ horny keratosis. Scar #14 was located on the left lower extremity. The maximum width of the scar was 15 cm and length was 18 cm. The scar was not painful, there were no signs of skin breakdown; and it was superficial. There was no inflammation, edema, or keloid formation. The VA examiner also found that there were no significant effects on occupation or ADLs. He further stated that there was no scarring on the left foot. There are at least five or more painful, unstable scars. Note (1) repeats the definition of an unstable scar is one where, for any reason, there is frequent loss of covering of skin over the scar. 38 C.F.R. § 4.118 (2012). Note (2) provides that if one or more scars are both unstable and painful, the rater is to add 10 percent to the evaluation that is based on the total number of unstable or painful scars. Id. Note (3) clarifies that scars evaluated under Diagnostic Code 7800, 7801, 7802, or 7805 may also receive an evaluation under Diagnostic Code 7804, when applicable. Regarding the period prior to August 30, 2002, the Board finds that the scars were superficial and painful on objective demonstration when he filed is claim for an increased rating. As such, the scars will remain properly accorded the maximum rating of 10 percent for this period. 38 C.F.R. § 4.118, Diagnostic Code 7804 (2002). As for the intervening period from August 30, 2002 up to October 22, 2008, the Board finds that the scars were superficial and painful on examination. As such, they are properly accorded the maximum rating of 10 percent for this intervening period. 38 C.F.R. § 4.118, Diagnostic Code 7804 (2002). No harm occurs to the Veteran by the application of the revised rating criteria, as this is the same rating he received under the earlier criteria. See also Bernard v. Brown, 4 Vet. App. 384 (1993). Regarding the period since October 23, 2008, in the regulations that became effective that day, there is clear intent to accord greater compensation based on the number of scars that are unstable and/or painful. No harm occurs to the Veteran by the application of these revised rating criteria, as, for reasons discussed below, he receives a higher rating under these criteria. As to the number of scars, the Veteran's testimony and the medical evidence indicate he has at least 5 painful scars from his SFWs. Even as a layman, he is competent to testify as to his consequent pain and to observe and describe these scars and their effects since this does not require any specialized medical knowledge, training, or expertise. See Jandreau v. Nicholson, 492 F.3d 1372, 1377 (Fed. Cir. 2007); Barr v. Nicholson, 21 Vet. App. 303, 310 (2007). His lay testimony concerning this also is credible, however, to in turn ultimately have probative value. See Layno v. Brown, 6 Vet. App. 465, 469 (1994) (distinguishing between competency ("a legal concept determining whether testimony may be heard and considered") and credibility ("a factual determination going to the probative value of the evidence to be made after the evidence has been admitted")). See also Rucker v. Brown, 10 Vet. App. 67, 74 (1997) (Competency is a legal concept determining whether testimony may be heard and considered by the trier of fact, whereas credibility is a factual determination going to the probative value of the evidence to be made after the evidence has been admitted.). This evidence from him carries a lot probative value or weight, in applying the rating criteria effective from October 23, 2008. In applying the benefit-of-the-doubt doctrine, the Board finds that the medical evidence confirms he has at least 5 (total) painful service-connected scars, which warrant a 30 percent rating with an additional 10 percent added on to the 30 percent rating for unstable scars for a total rating of 40 percent. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 3.321, 4.1, 4.2, 4.3, 4.7, 4.10 (2011); 4.118, Diagnostic Code 7804 (effective October 23, 2008). This is the maximum possible rating for five or more scars that are unstable or painful. 38 C.F.R. § 4.118, Diagnostic Code 7804 (2012). A 10 percent disability rating for the scars will be granted prior to October 23, 2008, but a higher 40 percent rating as of October 23, 2008, for painful scars under Code 7804. The Board also has considered whether evaluation of the Veteran's disability under any other Diagnostic Code would avail him of an even higher or separate rating. Separate and distinct manifestations attributable to the same injury, allow for compensation under different Diagnostic Codes. See Esteban, 6 Vet. App. 259; Fanning, 4 Vet. App. 225. Here, though, the Board is unable to identify other appropriate Diagnostic Codes that would address separate and distinct manifestations attributable to his scars. Nor do any other skin ratings appear applicable. Under various other rating criteria applicable to other types of scars during the period for appellate review, potential for higher ratings for such scars exists. However, none of those criteria apply here. For example, the evidence in this case does not show any limited motion or limited function associated with the Veteran's scars, or that the scars are deep (as opposed to superficial). See 38 C.F.R. § 4.118, Diagnostic Codes 7801, 7805 (2001). Diagnostic Code 7800 applies only to scars of the head, face, or neck, and is the only scar rating which considers any disfigurement. Traumatic Arthritis of the Left and Right Knees The Veteran asserts that his left and right knee disabilities should be rated higher because he has instability or giving away, sharp pain, swelling (4-5 times per week), and can only bend his left knee to about 15 degrees. (See January 1999 NOD). The claims of entitlement to higher ratings under DC 5257 (based on instability of his knees, apart from arthritis) are being remanded and therefore will not be discussed in this decision. The Board will only address DCs 5003, 5010, 5260, and 5261 pertaining to arthritis and consequent limitation of motion. The Veteran's left knee arthritis is currently rated as 10- percent disabling under 38 C.F.R. § 4.71a, DCs 5010, so on the premise that he has post-traumatic arthritis causing limitation of motion. He has an additional (separate) 20 percent rating under DC 5257 for left knee ligament instability as a residual of a SFW of this knee. On the other hand, the rating for his right knee disability is entirely under 38 C.F.R. § 4.71a, Diagnostic Code 5299-5257, so only on the premise of instability. Unlike his left knee, he does not have a separate rating for his right knee under DCs 5003 and 5010, although he does have a separate 40 percent rating for residuals of a through-and-through SFW of his right leg involving fractures of his tibia and fibula and complete paralysis of the peroneal nerve under DC 8521 and an additional 10 percent rating under DC 7804 for residuals, so including a scar, of a SFW to his right thigh. According to 38 C.F.R. § 4.71a, DC 5010, arthritis due to trauma, i.e., post-traumatic arthritis, if confirmed by X-ray, is rated as degenerative arthritis under DC 5003. DC 5003 indicates degenerative arthritis (hypertrophic or osteoarthritis) will be rated on the basis of limitation of motion under the appropriate DCs for the specific joint or joints involved - which, here, since concerning the knee, are DC 5260 for limitation of knee and leg flexion and DC 5261 for limitation of knee and leg extension. Further according to DC 5003, when the limitation of motion of the specific joint or joints involved is noncompensable (i.e., 0 percent) under the appropriate DCs, a rating of 10 percent is for application for each such major joint or group of minor joints affected by limitation of motion to be combined, not added, under DC 5003. Limitation of motion must be objectively confirmed by findings such as swelling, muscle spasm or satisfactory evidence of painful motion. Moreover, according to DC 5003, in the absence of limitation of motion, a 10 percent rating is warranted when there is X- ray evidence of involvement of 2 or more major joints or 2 or more minor joint groups. A higher 20 percent rating requires X-ray evidence of involvement of 2 or more major joints or 2 or more minor joint groups, with occasional incapacitating exacerbations. For purposes of rating disability from arthritis, the knee is considered a major joint. 38 C.F.R. § 4.45(f). Normal range of motion of the knee is from 0 degrees of extension to 140 degrees of flexion. 38 C.F.R. § 4.71a, Plate II. Under DC 5260, a 0 percent evaluation is awarded when flexion is limited to 60 degrees. A 10 percent evaluation is awarded when flexion is limited to 45 degrees. A 20 percent evaluation is warranted when flexion is limited to 30 degrees. And a 30 percent evaluation is assigned when flexion is limited to 15 degrees. Under DC 5261, a 0 percent rating is warranted when extension is limited to 5 degrees. Compensable ratings for limitation of extension are assigned when extension is limited to 10 degrees (10 percent), 15 degrees (20 percent), 20 degrees (30 percent), 30 degrees (40 percent) or 45 degrees (50 percent). VA's General Counsel has held that when a knee disability is rated under 38 C.F.R. § 4.71a, DC 5257, for "other" knee impairment including recurrent subluxation and lateral instability, and a Veteran also has limitation of knee motion that at least meets the criteria for a noncompensable evaluation under DC 5260 or 5261, separate evaluations may be assigned under DC 5257 for the recurrent subluxation and lateral instability and under DC 5003 for the arthritis causing limitation of motion under DC 5260 and/or 5261. If a Veteran does not meet the criteria for a noncompensable rating under either DC 5260 or 5261, there is no additional disability for which a separate rating for arthritis may be assigned. VAOPGCPREC 23-97 (July 1, 1997; revised July 24, 1997), published at 62 Fed. Reg. 63,604 (1997). However, if a rating is assigned under the provisions for "other" knee impairment (38 C.F.R. § 4.71a, DC 5257), a separate 10 percent rating may be assigned where there is X-ray evidence of arthritis and evidence of painful motion. See VAOPGCPREC 9-98 (August 14, 1998), published at 63 Fed. Reg. 56,704 (1998); 38 C.F.R. § 4.59. This is because, read together, 38 C.F.R. § 4.59 and DC 5003 provide that painful motion of a major joint (and, again, for purposes of rating disability from arthritis, the knee is considered a major joint, see 38 C.F.R.§ 4.45(f)), arthritis is deemed to be limited motion and entitled to a minimum 10 percent rating even though there is no actual limitation. See Lichtenfels v. Derwinski, 1 Vet. App. 484, 488 (1991). Separate ratings under DC 5260 (limitation of leg and knee flexion) and DC 5261 (limitation of leg and knee extension) also may be assigned for disability of the same joint. VAOPGCPREC 9-04 (September 17, 2004), published at 69 Fed. Reg. 59,990 (2004). Specifically, where a Veteran has both a limitation of flexion and a limitation of extension of the same leg, the limitations must be rated separately to adequately compensate for functional loss associated with injury to the leg. Id. Turning now to the relevant facts of this particular case. A January 1969 STR noted left knee joint opened and irrigated. A February 1969 STR noted multiple SFWs to the left knee with no artery or nerve involvement. (See February 10, 1969 STR). A May 1982 X-ray revealed narrowing of the left knee joint medially with associated subarticular sclerosis and marginal spurring. There were several small metallic fragments in the soft tissues about the knee. June 1983 radiographic x-rays of the knees demonstrated multiple small soft-tissue metallic fragments measuring up to 5 mm in diameter located adjacent to the medial femoral condyle and medial aspect of the fibular head. On the right there were four such fragments in the soft tissues posterior and lateral to the proximal tibia shaft at approximately the level of the fibular head. There was a little narrowing of the knee joint medially on the left with associated subarticular sclerosis and marginal spurring. He had DJD of the left knee and multiple soft tissue metallic fragments bilaterally. An August 1998 VA examination noted shrapnel in the left knee and complaints of pain with weight bearing. He ambulated around his house with a cane, but went to medical appointments in a wheelchair. He stated that he could not stand for prolonged period due to pain in his knees and left foot. With regards to the right knee, the Veteran reported moderate pain and instability. The left knee had a 10 cm longitudinal curvilinear anterior scar. There was a small effusion. Range of motion was zero to 90 degrees. There was moderate medial collateral ligamentous laxity with no crepitus. An August 1998 VA examination noted retained shrapnel of the right knee. Upon physical examination, the right knee was cool without effusion and range of motion was 0 to 192 degrees with no gross ligamentous laxity. A March 1999 VA treatment record noted increased left knee pain and crepitus. The Veteran was diagnosed with traumatic arthritis of the left knee. An April 2006 X-ray of the knees reflects medial joint space loss, mild degenerative changes, and left knee pain/weakness (possible internal derangement may have more advanced degenerative joint disease tha[n] radiographs suggest). A June 2006 VA treatment record noted that the Veteran had used a scooter for approximately 15 to 20 years. He was very limited in his ambulation for a variety of lower extremity and back/neck reasons. A June 2006 VA treatment record reflects complaints of pain and swelling of the left knee. He denied locking, catching, and giving out/weakness. Upon physical examination, there were no effusion, swelling, and laxity, negative anterior and posterior drawers. A July 2006 VA examination for left knee with ligament laxity reflects complaints of left knee pain that was a 10 out of 10 all the time. He complained of fatigue and lack of endurance. Precipitating factors included movement, sitting, standing, and swelling. Medication was an alleviating factor. With regard to ADLs, he could not walk or stand. Upon physical examination, there was no heat, redness, or soft tissue swelling about the left knee. There was no effusion. The examiner was unable to demonstrate any left knee instability ligament laxity at 0 and 30 degrees of flexion. Range of motion was from 0 degrees extension into 120 degrees flexion. He had 10 degrees internal and external rotation. McMurray's sign was negative on the left knee. The Veteran was diagnosed with mild DJD of the left knee. There was no ligament laxity or instability of the left knee. With regard to Deluca, there was a 20-degree loss of flexion due to pain repetitive use. There was generalized fatigability, weakness, lack of endurance but no incoordination of the left knee. Pain had a primary functional impact on the left knee. A July 2006 VA examination for the right knee reflects complaints of retained mortar fragments. The Veteran stated that his right knee was weaker than the left knee and that his pain averaged an 8 out of 10 (10 being the worst). He complained of weakness, stiffness, swelling, heat, redness, instability, locking, fatigue, and lack of endurance. Precipitating factors for the right knee were standing, walking, and bending. The right knee buckled under him. Alleviating factors included medication and minimal activity. The Veteran wore a knee brace in the past, but was currently wheelchair bound. Upon physical examination, there was no heat, redness, or soft tissue swelling. There was full range of motion, to include 120 degrees flexion, 0 degrees extension, 10 degrees internal and external rotation. There was no ligament laxity to varus or valgus stress at 30 degrees flexion. Anterior and posterior drawer signs were negative. McMurray's sign was negative on the right knee. Scar below the right knee was too extensive to measure (entire area below the right knee was scarred). He also had extensive atrophy of his right lower extremity. He also had a right foot drop. He was diagnosed with multiple retained mortar fragments about the right knee with mild DJD. With regard to Deluca, there was a 20 degree loss of flexion due to pain on repetitive use. There was moderate fatigability, weakness and lack of endurance of the right knee but no incoordination. Pain had a primary functional impact on the Veteran right knee. A September 2010 VA treatment records reflects, via X-ray, that the Veteran had a slight interval progression of moderate left knee osteoarthritis that involved the medial femorotibial joint compartment. There was no significant change in the mild right medial femorotibial joint space narrowing. There was no radiographic evidence of acute osseous injury of either knee or bilateral small knee effusions. An August 2011 VA joints examination of the knees reflects deformity, giving way, instability, pain, weakness, decreased joint motion, lack of endurance, locking episodes (several weekly), flare-ups of joint disease that was severe, weekly for 1 to 2 weeks. He did not have stiffness, incoordination, or effusions. The Veteran attributed the flare to motion, retained shrapnel fragment, and standing for short period of time. The Veteran was diagnosed with crepitus, tenderness, pain at rest, and weakness. He had no bumps consistent with Osgood-Schlatter's Disease, mass behind the knees, clicks or snaps, but had grinding, crepitation, and mild instability. He had abnormal anterior/posterior cruciate ligament stability in 30 degrees of flexion (3 mm anterior motion). His anterior/posterior cruciate ligament stability in 90 degrees of flexion was abnormal. He had patellar spurring, but no meniscus abnormality. For the left knee, flexion was to 83 degrees, extension of 0 degrees with objective evidence of pain. For the right knee, flexion was to 94 degrees, extension was normal. There was objective evidence of pain following repetitive motion. There was no additional limitation after three repetitions of range of motion. The Veteran was diagnosed with slight interval progression of moderate left knee osteoarthritis predominantly that involved medial femorotibial joint compartment. There was no significant change in mild right medial femorotibial joint space narrowing; no radiographic evidence of acute osseous injury of either knee; or bilateral small knee joint effusions. The Veteran was diagnosed with traumatic arthritis of the left knee with residual SFWs and ligament instability and mild osteoarthritis of the right knee with residual SFWs. Occupationally, there was decreased mobility; difficulty with lifting, carrying, weakness or fatigue; and decreased strength, and pain. ADLs reflect, at the very least, severe impairment of chores and traveling; prevention of shopping, exercise, sports, recreation, and driving, and moderate impairment on dressing and mild impairment on feeding, bathing, toileting, and grooming. This collective body of medical evidence shows the Veteran now suffers from osteoarthritis of both knees, so not just in his left knee. And as already explained, according to 38 C.F.R. § 4.71a, DC 5003, degenerative arthritis (to include hypertrophic or osteoarthritis), established by X-ray findings, will be rated on the basis of limitation of motion under the appropriate DCs for the specific joint or joints involved (here, DC 5260 for limitation of flexion of the leg and knee, and DC 5261 for limitation of extension of the leg and knee). When, however, the limitation of motion of the specific joint or joints involved is noncompensable (meaning 0-percent disabling) under the appropriate DCs, a 10 percent rating is assignable for each such major joint or group of minor joints affected by limitation of motion, to be combined, not added, under DC 5003. See also 38 C.F.R. § 4.71a, DC 5010 (indicating that arthritis due to trauma, substantiated by x-ray findings, should be evaluated as degenerative arthritis). Limitation of motion must be objectively confirmed by findings such as swelling, muscle spasm, or satisfactory evidence of painful motion. See DC 5003. The medical evidence of record establishes that the symptoms associated with the Veteran's left knee disability consist of painful motion, mild DJD with flexion of 120 degrees with a 20 degree loss of flexion due to pain on repetitive use during the July 2006 VA examination and flexion of 83 degrees with normal extension during the September 2010 VA examination. It was also noted that he had "moderate" left knee osteoarthritis with slight interval progression predominantly involved in the medial femoratibial joint space narrowing. (See September 2010 VA examination). With regard to the right knee, he had full range of motion with a diagnosis of mild DJD with 20 percent loss of flexion due to pain on repetitive motion during the July 2006 VA examination. He had flexion of 94 degrees with normal extension and pain with repetitive motion, but no additional limitation after three repetitions. He was diagnosed with mild osteoarthritis of the right knee. (See September 2010 VA examination). While he also has complained of crepitus (described as a clicking or grinding sensation), such is not shown to result in additional functional loss. The medical evidence has documented some instability/laxity for the right and left knee. In fact, such apparently was the basis for the assignment of the 10 percent rating under DC 5257 for the right knee. However, again, the claim for a higher rating under this DC for the instability component of the disability is being remanded for additional development and will be considered at a later time with the muscle-disability claims. In the meantime, separate evaluation of the right knee disability under DC 5003 would result in no more than a 10 percent evaluation. The Board notes, initially, that the evidence does not show the Veteran has limitation of motion of his knees to a compensable degree. As already alluded to, standard range of motion of the knee is from 0 to 140 degrees (extension to flexion). See Diagnostic Code 4.71, Plate II. Although it is undisputed he has some limitation of motion in his right and left knees because of his osteoarthritis, there clearly is no basis for a compensable evaluation under either DC 5260 (requiring flexion limited to 45 degrees or less) or DC 5261 (requiring extension limited to 10 degrees or more). Nevertheless, given his credible complaints of pain, which could, conceivably, limit his range of motion beyond that objectively shown, a separate 10 percent rating for his right knee is assignable under DC 5003 (consistent with 38 C.F.R. § 4.59). See also Burton v. Shinseki, 25 Vet. App. 1, 5 (2011) (holding that the painful motion provisions of 38 C.F.R. § 4.59 are not limited solely to claims involving arthritis of a joint). Although he had 20 degrees of loss of flexion after repetitive use during the July 2006 VA examination, his flexion was to 120 degrees initially. This decrease in range of motion is not evidence of functional loss of sufficient severity to warrant a higher disability evaluation, meaning exceeding 10 percent. Moreover, he is not entitled to a rating exceeding 10 percent for either knee because there is no X-ray evidence of involvement of 2 or more major joints or 2 or more minor joint groups with occasional incapacitating exacerbations. Accordingly, the Board finds that a separate 10 percent rating under DC 5003/5010 for the right knee arthritis is warranted (like he already has for his left knee). However, he is not shown to be entitled to any higher rating for either knee, at least not as concerning the arthritis component of his knee disabilities. Furthermore, at no time since he filed these claims have the disabilities been more disabling because of the arthritis, in turn precluding the Board from "staging" these ratings. Hart, supra. Hepatitis C and Liver Laceration The Veteran's Hepatitis C is currently evaluated as 60- percent disabling effective February 5, 1998 under 38 C.F.R. § 4.114, DC 7345, for chronic liver disease without cirrhosis, including Hepatitis C, and vagotomy with pyloroplasty or gastroenterostomy. He had a noncompensable rating from October 17, 1970 to February 4, 1998. In a February 2002 rating decision, he was awarded a separate rating for postoperative liver laceration residuals, effective July 2, 2001, which encompassed complaints of pulling in his back, a painful abdominal area, and findings of palpable adhesions. (See July 2001 and February 2002 rating decisions). He was assigned a 10 percent rating for post-operative liver laceration residuals under DCs 7311-7301. The RO assigned separate evaluations based on the date of the schedule revision, effective July 2, 2001. There are diseases of the digestive system, particularly within the abdomen, which, while differing in the site of pathology, produce a common disability picture characterized in the main by varying degrees of abdominal distress or pain, anemia, and disturbances in nutrition. Consequently, certain coexisting diseases in this area, as indicated in the instruction under the title "Diseases of the Digestive System," do not lend themselves to distinct and separate disability evaluations without violating the fundamental principle relating to pyramiding as outlined in 38 C.F.R. §§ 4.14; 4.113. In turn, VA regulation provides that ratings under DCs 7301 to 7329, inclusive; 7331, 7342, and 7345 to 7348, inclusive, will not be combined with each other. Rather, a single evaluation will be assigned under the DC that reflects the predominant disability picture, with elevation to the next higher evaluation where warranted by the overall severity. See 38 C.F.R. § 4.114. During the pendency of this appeal, the criteria for rating diseases of the digestive system were amended. These changes affected the evaluation of liver disorders and diseases. See 66 Fed. Reg. 29,486-29,489 (effective July 2, 2001) (codified at 38 C.F.R. § 4.114 (2004)). Effective July 2, 2001, VA revised its criteria for rating disability of the digestive system, to include a renumbering of the DCs. See 66 Fed. Reg. 29486-29489 (May 31, 2001). The Board may only consider and apply the "new" criteria as of the effective date of enactment, but may apply the "old" criteria for the entire appeal period. 38 U.S.C.A. § 5110(g) (West 2002); VAOPGCPREC 3-2000 (Apr. 10, 2000). Under the "old" criteria, a closely analogous diagnostic code pertained to injury of the liver under Diagnostic Code 7311. A noncompensable rating was assigned for healed injury with no residuals. 38 C.F.R. § 4.114, Diagnostic Code 7311 (2000-01). With residual disability, the disability was rated according to the criteria for peritoneal adhesions. Id. A 10 percent rating was warranted for moderate disability with pulling pain on attempting work or aggravated by movements of the body, or occasional episodes of colic pain, nausea, constipation (perhaps alternating with diarrhea) or abdominal distention. 38 C.F.R. § 4.114, Diagnostic Code 7301 (2000-01). The revised criteria of Diagnostic Code 7311 indicated that residuals of liver injury were to be rated with respect to the specific residuals as adhesions of peritoneum (diagnostic code 7301), cirrhosis of liver (diagnostic code 7312) and chronic liver disease without cirrhosis (diagnostic code 7345). The criteria for Diagnostic Code 7301 did not undergo a substantive change. Generally, in a claim for an increased rating, where the rating criteria are amended during the course of the appeal, the Board considers both the former and the current schedular criteria because, should an increased rating be warranted under the revised criteria, that award may not be made effective before the effective date of the change. See Kuzma v. Principi, 341 F.3d 1327 (Fed. Cir. 2003) (overruling Karnas v. Derwinski, 1 Vet. App. 308, 312-13 (1991), to the extent it held that, where a law or regulation changes after a claim has been filed or reopened but before the administrative or judicial appeal process has been concluded, the version more favorable to appellant should apply). See also VAOPGCPREC 7-2003 (Nov. 19, 2003); VAOPGCPREC 3-2000 (April 10, 2000); 38 U.S.C.A. § 5110(g) (West 2002); 38 C.F.R. § 3.114 (2004); Rhodan v. West, 12 Vet. App. 55, 57 (1998), appeal dismissed, No. 99-7041 (Fed. Cir. Oct. 28, 1999) (unpublished opinion) (although a liberalizing regulation cannot be applied retroactively unless the regulation contains language that permits it to be so applied, the Veteran does get the benefit of having both the old regulation and the new regulation considered for the period after the change was made during the pendency of the claim); 38 U.S.C.A. § 5110(g) (West 2002). Therefore, the Board will review the disability under the old and new criteria. The Board sees the RO evaluated the Veteran's claim under the old regulations in making its rating decision dated in December 1999 and July 2001. Whereas the RO considered the new rating criteria in its February 2002 rating decision. The Veteran was afforded an opportunity to comment on the RO's action. Accordingly, there is no prejudice to him under Bernard v. Brown, 4 Vet. App. 384 (1993). His service-connected Hepatitis C is now evaluated as 60- percent disabling under DC 7354 for Hepatitis C with postoperative liver laceration residuals. It was rated as noncompensable from October 17, 1970 (previously DC 7399- 7311, postoperative liver laceration residuals only); and has been rated as 60-percent disabling effectively since February 05, 1998 (Hepatitis C only from July 2, 2001). When an unlisted condition is encountered it will be permissible to rate under a closely related disease or injury in which not only the functions affected, but the anatomical localization and symptomatology are closely analogous. 38 C.F.R. 4.20. Ratings under DCs 7301 to 7329, inclusive, 7331, 7342, and 7345 to 7348, inclusive, will not be combined with each other. Instead, a single evaluation will be assigned under the diagnostic code that reflects the predominant disability picture, with elevation to the next higher evaluation where the severity of the overall disability warrants such elevation. Of significance here are the new criteria for the evaluation of hepatitis C, now found under 38 C.F.R. § 4.114, DC 7354 (2012). Under the old regulations, effective prior to July 2, 2001, cirrhosis of the liver, 38 C.F.R. § 4.114, Diagnostic Code 7312 (2001), and infectious hepatitis, DC 7354 (2001), could not be combined. If a Veteran had both conditions, a single evaluation was assigned under the diagnostic code that reflected the predominant disability picture, and the rating was raised to the next higher level if the overall disability warranted. 38 C.F.R. § 4.114. The probative medical evidence, including findings of the recent VA examination is not referable to cirrhosis of the liver. See 38 C.F.R. § 4.414, DC 7312, effective prior to and after July 2, 2001. For evaluation under DC 7312, documentation of cirrhosis (by biopsy or imaging) and abnormal liver function tests must be present. Id., effective July 2, 2001. Effective prior to and after July 2, 2001, weight loss remains a criterion for a higher disability rating under DCs 7312 and 7345; additionally, the provisions of 38 C.F.R. § 4.112, prior to July 2, 2001, concerning weight loss, are applicable to this issue and have been changed. Minor weight loss or greater losses of weight for periods of brief duration are not considered of importance in rating. 38 C.F.R. § 4.112 (2001), effective prior to July 2, 2001. Rather, weight loss becomes of importance where there is appreciable loss that is sustained over a period of time. Id. In evaluating weight loss generally, consideration will be given not only to standard age, height, and weight tables, but also to the particular individual's predominant weight pattern as reflected by the records. Id. The use of the term "inability to gain weight" indicates that there has been a significant weight loss, with inability to regain it despite appropriate therapy. Id. Under the current regulations, effective July 2, 2001, VA revised section 4.112, pertaining to weight loss. 38 C.F.R. § 4.112 (2004), effective July 2, 2001. The revised version of § 4.112 adds definitions of "substantial weight loss, minor weight loss, inability to gain weight, and baseline weight" to be used in diagnostic codes found under section 4.114. Under the revised regulation: For purposes of evaluating conditions in § 4.114, the term "substantial weight loss" means a loss of greater than 20 percent of the individual's baseline weight, sustained over three months or longer; and the term "minor weight loss" means a weight loss of 10 to 20 percent of the individual's baseline weight, sustained for three months or longer. The term "inability to gain weight" means that there has been substantial weight loss with inability to regain it despite appropriate therapy. "Baseline weight" means the average weight for the two-year- period preceding onset of the disease. 38 C.F.R. § 4.112 (2004). Under old regulations, effective prior to July 2, 2001, for DC 7345, which evaluates hepatitis C, a 30 percent rating was assigned for minimal liver damage with associated fatigue, anxiety, and gastrointestinal disturbance of lesser degree and frequency but necessitating dietary restriction or other therapeutic measures. 38 C.F.R. § 4.114, DC 7345 (2001), effective prior to July 2, 2001. A 60 percent evaluation was warranted for moderate liver damage and disabling recurrent episodes of gastrointestinal disturbance, fatigue, and mental depression. Id. Finally, a 100 percent rating was assigned for marked liver damage manifested by liver function test and marked gastrointestinal symptoms, or with episodes of several weeks duration aggregating three or more a year and accompanied by disability symptoms requiring rest therapy. Id. Under the current regulations, effective July 2, 2001, for DC 7354, for evaluating hepatitis C, reflects that a 40 percent evaluation is warranted for daily fatigue, malaise, and anorexia, with minor weight loss and hepatomegaly; or incapacitating episodes (with symptoms such as fatigue, malaise, nausea, vomiting, anorexia, arthralgia, and right upper quadrant pain) having a total duration of at least four weeks, but less than six weeks, during the past 12- month period. 38 C.F.R. § 4.114, DC 7354 (2004), effective July 2, 2002. A 60 percent evaluation is assigned for daily fatigue, malaise, and anorexia, with substantial weight loss (or other indication of malnutrition), and hepatomegaly; or incapacitating episodes (with symptoms such as fatigue, malaise, nausea, vomiting, anorexia, arthralgia, and right upper quadrant pain) having a total duration of at least six weeks during the past 12-month period, but not occurring constantly. Id. A 100 percent evaluation is assigned for near-constant debilitating symptoms (such as fatigue, malaise, nausea, vomiting, anorexia, arthralgia, and right upper quadrant pain). Id. For purposes of rating Hepatitis C, an "incapacitating episode" means a period of acute signs and symptoms severe enough to require bed rest and treatment by a physician. 38 C.F.R. § 4.114, Diagnostic Code 7354 Note (2) (2012). In order for the Veteran to receive the next higher rating of 100 percent under DC 7345, the disability picture associated with his service-connected Hepatitis C must more nearly approximate near constant debilitating symptoms such as fatigue, malaise, nausea, vomiting, anorexia, arthralgia, and right upper quadrant pain. See also 38 C.F.R. § 4.7. However, no such disability picture is shown by the evidence. A February 1969 STR noted that he had a small liver perforation. He had drains that were removed and a suture. (See also February 10, 1969 STR). A June 1983 radiographic report noted no enlargement of the liver. An August 1998 VA treatment record noted a history of abnormal liver tests and thrombocytopenia. A December 1998 VA treatment record noted that liver function tests normalized with abstinence. He did not require any therapy at that time. An August 1998 VA examination noted that the liver was 12 cm to percussion, not palpable below costal margin. There was no rebound, guarding or shifting of fluid wave. Another August 1998 VA treatment record noted a history of abnormal liver tests and thrombocytopenia. The liver was not palpable below the costal margin. X-ray of the abdomen was normal and liver function tests were normal. A September 1999 VA treatment record noted elevated liver function tests. An August 2001 VA examination noted elevated liver function test results with complaints of severe fatigue, daily morning nausea, vomiting every other day, pulling in back, a painful abdominal area, colic every other day with nausea, fever once a month, slight abdominal distention, and taking pain medications. The VA examiner noted that the Veteran weighed 144 pounds, 5 ft. 8 inches tall, had a jaundiced appearance, a soft abdomen with palpable adhesions, bowel sounds present in all quadrants, tenderness in all four quadrants on palpation, and palpable enlargement of the liver at the right upper quadrant. A July 2006 VA examination for the liver reflects that the Veteran had multiple blood transfusions for his in service injuries. He stated that his liver function tests elevated over the years and in 2001 he was diagnosed with hepatitis C. He had never had a liver biopsy or has been treated for hepatitis C, but was told that he had cirrhosis. He complained of fatigue, malaise, vomiting (4 to 5 times in the morning), nausea, poor appetite, general arthralgia, and right upper quadrant discomfort on a daily basis. The examiner stated that it was unclear whether the symptoms were severe enough that any physician ever prescribed bed rest and treatment. The Veteran was diagnosed with chronic hepatitis C. An August 2007 VA treatment records reflect that the Veteran had high viral load with suspected cirrhosis. He was referred for a clinical evaluation of elevated AFP-25. He did not have any problems with his liver or GI tract. His weight had been stable. He reported no history of intravenous drug use. An April 2011 VA treatment record reflected that the Veteran's hepatitis C was still active and he elected to go untreated in light of his autoimmune disorder. In a June 2011 VA treatment record, the Veteran denied fevers, hematemesis, abdominal pain, diarrhea, jaundice and melena. An August 2011 VA examination of the gall bladder and liver reflects a history of liver trauma. The Veteran had a liver laceration with three shrapnel pieces removed during service. He had no incapacitating episodes during the past 12 months. There was a history of chronic liver disease. There were no extra-hepatic manifestations of the Veteran's liver disease. He had daily fatigue, near-constant malaise, intermittent nausea, intermittent vomiting, and near- constant anorexia. There was no evidence of malnutrition and his abdominal examination was normal. The Veteran was diagnosed with chronic hepatitis C. There were no effects of the problem on usual daily activities. The Veteran was also diagnosed with a liver laceration s/p surgical repair. There were no significant effects on ADLs. A September 2011 VA treatment record noted that the Veteran had a history of high viral HCV genotype 1BB and was suspected to have liver cirrhosis. His AFP had been steadily increasing over several years; however, last CT abdomen in September 2010 did not show liver masses. No therapy for HCV infection was initiated due to psoriatic flare. The medical evaluation and treatment records discussed above are entitled to probative weight and provide evidence against the Veteran's claim. His testimony and statements are credible and also entitled to probative weight, but they are outweighed by the medical evidence of record, which shows his symptoms are not near-constant and debilitating. Under the former criteria, a 100 percent rating is clearly not warranted because marked liver damage manifested by liver function tests and marked gastrointestinal symptoms, or with episodes of several weeks duration, aggregating three or more a year, and accompanied by disabling symptoms requiring rest therapy is not shown by the evidence of record. The Veteran's gastrointestinal problems as related to the Hepatitis C have not required rest therapy nor have they been shown to be of several weeks' duration, aggregating three or more a year. 38 C.F.R. § 4.114, Diagnostic Codes 7311, 7312, 7343, 7344, and 7345, effective prior to July 2, 2001. As noted, effective July 2, 2001, Diagnostic Code 7345 was amended and is currently used to rate chronic liver disease without cirrhosis, excluding Hepatitis C. DC 7354 now contains criteria for evaluating Hepatitis C. DC 7311 is for residuals of liver injury, DC 7312 is for cirrhosis, and DC 7313 is for liver abscess. Under the new regulations, currently in effect, Hepatitis C is evaluated under Diagnostic Code 7354, and a 60 percent evaluation is assigned for daily fatigue, malaise, and anorexia, with substantial weight loss (or other indication of malnutrition), and hepatomegaly; or incapacitating episodes (with symptoms such as fatigue, malaise, nausea, vomiting, anorexia, arthralgia, and right upper quadrant pain) having a total duration of at least six weeks during the past 12-month period, but not occurring constantly. A 100 percent evaluation is assigned for near- constant debilitating symptoms (such as fatigue, malaise, nausea, vomiting, anorexia, arthralgia, and right upper quadrant pain). VA regulation also provide that sequelae, such as cirrhosis or malignancy of the liver, are to be evaluated under an appropriate diagnostic code, but the same signs and symptoms cannot be used as the basis for evaluation under DC 7354 and under a diagnostic code for sequelae. 38 C.F.R. §§ 4.114; DC 7354, Note (1) (2004). While the records also show the Veteran reported symptoms such as daily fatigue, near-constant malaise, intermittent nausea, intermittent vomiting, and near-constant anorexia, they do not support a higher 100 percent rating under DC 7345. As explained, in order to meet the requirements for this higher 100 percent rating, he must have near-constant debilitating symptoms such as fatigue, malaise, nausea, vomiting, anorexia, arthralgia, and right upper quadrant pain. 38 C.F.R. § 4.114. Although he has reported experiencing some of these symptoms such as fatigue, nausea, vomiting, and epigastric pain, with some on a near-constant basis such as malaise and anorexia, the objective medical evidence has shown them to be, at most, moderately disabling. For example, the August 2011 VA examiner found that there was no evidence of malnutrition and the Veteran's abdominal examination was normal. Further, there were no effects of the problem on ADLs. This evidence militates against a finding of near-constant and debilitating symptoms. The records concerning his evaluation and treatment do not show evidence of malnutrition or unintended weight loss. In fact, the August 2007 VA treatment record noted that his weight had been stable. There is no evidence of record that he has anorexia, as his weight has remained essentially constant. The record shows he uses a wheel chair, but this has not been attributed to his service-connected Hepatitis C. See Mittleider v. West, 11 Vet. App. 181, 182 (1998) (VA adjudicators must be able to distinguish, by competent medical evidence, the extent of symptoms that is due to service-related causes, i.e., service-connected disability, from that which is not). Accordingly, the evidence supports at most a 60 percent rating for his Hepatitis C. 38 U.S.C.A. § 5107(b), Gilbert v. Derwinski, 1 Vet. App. at 53. The Board recognizes that the August 2001 VA examiner noted the Veteran demonstrated tenderness in all four quadrants on palpation, and palpable enlargement of the liver at the right upper quadrant. The August 2011 VA examiner stated there was no history of chronic liver disease. Therefore, a higher rating under 7312 (cirrhosis of the liver) is not warranted. With regards to a liver laceration, the post-operative liver laceration residuals are manifested by pulling in the back, a painful abdominal area, and findings of palpable adhesions. Such symptomatology falls squarely within the scheduler criteria for 10 percent rating under DCs 7311-7301 (2001). Finally we note that, in view of the holding in Hart, supra, the Board has considered whether the Veteran is entitled to a "staged" rating for his service-connected Hepatitis C and liver laceration disabilities, as the Court indicated can be done in this type of case. He has not shown the required variance in the severity of his disability to warrant the staging of his rating, however. The Board finds that the evidence clearly does not represent near-constant and debilitating symptoms as required for the next higher 100 percent disability rating for Hepatitis C, nor a rating exceeding 10 percent for residuals of the liver laceration. Therefore, the preponderance of the evidence is against these claims, in turn meaning the benefit- of-the- doubt rule does not apply, and these claims must be denied. 38 C.F.R. § 4.3. Hemorrhoids The RO granted service connection for hemorrhoids and assigned a noncompensable rating effective from February 5, 1998. The Veteran seeks an increased rating and asserts his hemorrhoids are more severe than what is contemplated by a noncompensable rating. Hemorrhoids are rated under 38 C.F.R. § 4.114, Diagnostic Code 7336. Under Diagnostic Code, 7736, mild or moderate hemorrhoids are noncompensable. See 38 C.F.R. § 4.114, Diagnostic Code 7336. The criteria for the next higher rating, 10 percent, are external or internal hemorrhoids that are large or thrombotic, irreducible, with excessive redundant tissue, evidencing frequent recurrences. Id. The criteria for a 20 percent rating, the maximum schedular rating, are hemorrhoids with persistent bleeding with secondary anemia or with fissures. Id. The Veteran asserts he has itchy burning anal pain and bleeding after using the toilet. (January 1999 NOD). The August 1998 VA examination noted that the rectal areas revealed wasting of the right gluteus maximus muscle with external hemorrhoids. The Veteran was diagnosed with external hemorrhoids secondary to gluteus maximum muscle trauma in service with resulting atrophy and prolonged bedridden status associated with recovery from shrapnel injuries. A July 2006 VA examination for hemorrhoids reflects that the Veteran had anoscopy 4 years prior. He was not constipated and has not had surgery. He had occasional bleeding and his rectal area was itchy. He used medicated Vaseline products and Tucks pad. There was no functional impact other than an annoyance on his ADLs. Upon physical examination, there were no external hemorrhoids. The Veteran was diagnosed with internal hemorrhoids. A June 2011 VA treatment record reflects that the Veteran had hemorrhoids and occasionally bled when he wiped. In an August 2011 VA examination, the examiner noted that the Veteran's hemorrhoids were intermittent with remissions. He used medicated Vaseline for treatment. He had occasional rectal bleeding, but no anal itching, burning, diarrhea, difficulty passing stoo1, pain, tenesmus, or swelling. He had a recurrence without thrombosis 2 times per year. There was no history of fecal incontinence or perianal discharge. There was no anorectal fistula, stricture, or rectal prolapse. Hemorrhoids were not present upon examination and had no effect on ADLs. The evidence does not demonstrate that the Veteran's hemorrhoids have been irreducible with excessive redundant tissue and frequent recurrences; therefore, the findings do not more nearly approximate or equate to the criteria for a 10 percent rating, the minimal compensable rating under Diagnostic Code 7336. The Board acknowledges the Veteran's statements that his hemorrhoid disability is more severe than what is represented by a noncompensable rating. The Board notes that the Veteran is competent to give evidence about what he experiences; for example, he is competent to discuss current pain and other experienced symptoms. See Layno v. Brown, 6 Vet. App. 465 (1994). Furthermore, the Board finds the Veteran's testimony to be credible. See Barr v. Nicholson, 21 Vet. App. 303, 307-08 (2007); Washington v. Nicholson, 19 Vet. App. 362, 368-69 (2005). However, while the Veteran is competent to describe his symptoms, the combination of his lay statements and his VA physical examinations fails to demonstrate that he meets the criteria for the assignment of a 10 percent rating. The Board has also considered whether the manifestations of the Veteran's hemorrhoids warrant a separate rating under other diagnostic codes for the rectum. See 38 C.F.R. § 4.114, Diagnostic Codes 7332-7335 (2012). The evidence of record shows that the Veteran does not have a mild prolapsed rectum with constant slight or occasional moderate leakage, stricture of the anus with moderate reduction of lumen or moderate constant leakage, impairment of sphincter control or fistula in ano. Thus, the Veteran is not entitled to a higher disability rating or separate rating under Diagnostic Codes 7332, 7333, 7334, and 7335. At no time has this service-connected condition been more disabling than as currently rated, so the Board cannot stage the rating. Hart, supra. The Board finds the current noncompensable rating appropriately addresses the severity of the Veteran's symptoms. As the preponderance of the evidence is against the claim, the benefit of the doubt rule is inapplicable. See 38 U.S.C.A. § 5107(b); 38 C.F.R. § 4.3; Gilbert v. Derwinski, 1 Vet. App. 49, 54-56 (1990). Extra-schedular Consideration There is no evidence of exceptional or unusual circumstances to warrant referring these claims for extra-schedular consideration. 38 C.F.R. § 3.321(b)(1). Ordinarily, the VA Rating Schedule will apply unless there are exceptional or unusual factors that would render application of the schedule impractical. See Fisher v. Principi, 4 Vet. App. 57, 60 (1993). The question of an extra-schedular rating is a component of a claim for an increased rating. See Bagwell v. Brown, 9 Vet. App. 337, 339 (1996). And although the Board may not assign an extra-schedular rating in the first instance, it must specifically adjudicate whether to refer a case for extra-schedular evaluation when the issue either is raised by the claimant or reasonably raised by the evidence of record. Barringer v. Peake, 22 Vet. App. 242 (2008). The Court has clarified the analytical steps necessary to determine whether referral for extra-schedular consideration is warranted. See Thun v. Peake, 22 Vet. App. 111 (2008), aff'd, Thun v. Shinseki, 572 F.3d 1366 (Fed. Cir. 2009). First, there must be a determination of whether the evidence presents such an exceptional disability picture that the available schedular evaluation for the service-connected disability is inadequate. Second, if the schedular evaluation does not contemplate the Veteran's level of disability and symptomatology and is found inadequate, there must be a determination of whether the Veteran's exceptional disability picture exhibits other related factors such as those provided by the regulation as "governing norms." Third, if the rating schedule is inadequate to evaluate a Veteran's disability picture and that picture has attendant thereto related factors such as marked interference with employment or frequent periods of hospitalization, then the case must be referred to the Under Secretary for Benefits or the Director of the Compensation and Pension Service to determine whether, to accord justice, the Veteran's disability picture requires the assignment of an extra- schedular rating under 38 C.F.R. § 3.321(b)(1). The Board finds no such evidence in this particular instance, however. The Veteran's complaints related to his low back, scars on his left foot and heel, residuals of the laparotomy, post-operative liver laceration, traumatic arthritis of his right and left knees, Hepatitis C, and hemorroids are considered under the appropriate DCs. His primary symptoms are arthritic pain and consequent limitation of motion, a pulling sensation in his back, painful abdominal area, palpable adhesions, fatigue, malaise, nausea, vomiting, occasional bleeding from his rectal area and itchiness, tender painful scars, and limited range of motion, painful motion, subluxation, and instability of the bilateral knees. All of his symptoms are accounted for in the regular schedular rating criteria. According to 38 C.F.R. § 4.1, generally, the degrees of disability specified in the Rating Schedule are considered adequate to compensate for considerable loss of working time from exacerbations or illnesses proportionate to the severity of the several grades of disability. Indeed, in Van Hoose v. Brown, 4 Vet. App. 361, 363 (1993), the Court reiterated this, noting the disability rating, itself, is recognition that industrial capabilities are impaired. Moreover, although he was initially hospitalized when the original injuries occurred, owing to their gravity, the overwhelming majority of the evaluation and treatment for these disabilities he has received since has been on an outpatient basis, not instead as an inpatient, certainly not frequent inpatient. Thus, as the assigned schedular evaluations for these service-connected disabilities are adequate, referral for an extra-schedular rating is unnecessary. Thun, supra. See also Bagwell v. Brown, 9 Vet. App. 237, 238-9 (1996); Floyd v. Brown, 9 Vet. App. 88, 96 (1996); Shipwash v. Brown, 8 Vet. App. 218, 227 (1995); and VAOPGCPREC 6-96 (August 16, 1996). ORDER The claim for an initial rating higher than 40 percent for the DJD of the lumbar spine is denied. Prior to October 23, 2008, a rating higher than 10 percent for the painful scars from the SFWs and laparotomy is denied. But as of October 23, 2008, a higher 40 percent rating is granted for the scars from the SFWs and laparotomy, subject to the statutes and regulations governing the payment of VA compensation. The claim of entitlement to a rating higher than 10 percent for the left knee traumatic arthritis is denied. But a separate 10 percent rating is granted for the osteoarthritis and consequent painful motion of the right knee, subject to the laws and regulations governing the payment of compensation. A rating higher than 10 percent for the post-operative liver laceration residuals is denied. A rating higher than 60 percent for the Hepatitis C is denied. A compensable rating for the hemorrhoids is denied. REMAND Unfortunately, the remaining claims again must be remanded. Although the Board sincerely regrets the additional delay that inevitably will result, it is necessary to ensure there is a complete record upon which to decide these remaining claims so the Veteran is afforded every possible consideration. At the time of the VA examination in August 2011, the VA examiner found no active evidence of seborrheic dermatitis. The Veteran was diagnosed with seborrheic dermatitis not present on examination and plaque psoriasis with psoriatic arthritis. A remand for a new VA examination during a flare-up of the seborrheic dermatitis, if possible, is required. See 38 U.S.C.A. § 5103A(d) (West 2002); "A remand by . . . the Board confers on the Veteran or other claimant, as a matter of law, the right to compliance with the remand orders." See Stegall v. West, 11 Vet. App. 268, 271 (1998); Barr v. Nicholson, 21 Vet App 303 (2007) (holding that when VA undertakes to provide the Veteran with an examination, it must insure the examination is adequate); Ardison v. Brown, 6 Vet. App. 405 (1994) (holding that when evidence reflects that a disability has a history of remission and recurrence, the duty to assist requires that any examination be given during an active stage of the condition); Caffrey v. Brown, 6 Vet. App. 377 (1994) (holding that when a claimant asserts that the severity of a disability has increased since the most recent rating examination, an additional examination is appropriate). The Veteran's cooperation in scheduling another VA skin examination in order to ascertain the severity of his service-connected skin conditions during a flare-up or when they are active is essential in permitting a VA compensation examiner to ascertain the nature and full extent of the disorders. In Ardison v. Brown, 6 Vet. App. 405 (1994), the Court held that VA was obligated to evaluate tinea pedis, a skin condition, while in an "active stage" of the disease in order to fulfill the duty to assist. In Voerth v. West, 13 Vet. App. 117 (1999), however, the Court stated that a new examination was warranted in Ardison because active tinea pedis was a condition that would exist for weeks or months. The holding in Ardison did not apply in Voerth because an orthopedic disability is different from a skin condition. A flare-up lasting only one or two days not only renders a new VA examination impractical, but a "person who experiences a worsened condition only for a few days out of a year simply is less impaired than someone who suffers from the worsened condition for weeks or months." Voerth, at 123. This claim concerning the rating for the skin condition at hand is more akin to the situation in Ardison, if indeed not identical to it, requiring the scheduling of this additional VA compensation examination. With regards to the right elbow disability, the Veteran claims this disability is secondary to his service-connected seborrheic dermatitis. He was also diagnosed with plaque psoriasis with psoriatic arthritis, which subsequently was determined service connected in a September 2012 rating decision (the RO assigned a 10 percent rating effective April 28, 2005). The VA examiner did not provide an etiology opinion as to whether the alleged elbow disorder (claimed as tendonitis) was related to the service-connected seborrheic dermatitis or psoriatic arthritis. This claim therefore must be remanded for the necessary medical comment concerning this. See Stegall and Barr, supra. With regard to the issues concerning the SFWs to the left ankle, left knee, right knee, and left upper extremity above the elbow, the medical evidence of record reflects that the Veteran has retained foreign bodies in these areas requiring consideration of entitlement to a separate compensable evaluation for any muscle or nerve injury. The evidence of record reflects that pain and certain abnormalities, such as mild atrophy, have been noted in some muscle groups. However, the evidence does not establish whether a specific muscle group or groups has sustained actual muscle injury, or whether the symptoms and findings noted are simply abnormality in the use of the muscles. Further, it is unclear whether atrophy is present in the areas of the retained foreign bodies (RFBs) or whether there is actual injury to the muscle or whether the atrophy results from disuse or other cause. Further medical evidence and opinion must be obtained to determine which MGs are affected and to what severity. When there is evidence of RFBs, which had not been related to particular MGs, the Veteran maybe entitled to additional compensation if it is shown that none of the symptoms due to separate conditions are overlapping, else that would violate 38 C.F.R. § 4.14, VA's anti-pyramiding regulation. See 38 C.F.R. § 4.25(b) (2012) and Esteban v. Brown, 6 Vet. App. 259 (1994) (finding that when a Veteran has separate and distinct manifestations from the same injury he should be compensated under different DCs). Additionally, the claim for a rating higher than 20 percent for the residuals of the SFW to the right lung with retained fragments is inextricably intertwined with the claim (which the Board is separately referring) that the November 18, 1970 rating decision contains CUE. (See November 2008 Written Statement). In a November 2012 Post-Remand Brief, the Veteran asserted that he was entitled to a higher rating in excess of 20 percent for the residuals of the SFW to his right lung with retained fragments. He asserts that the DCs 6818-5321 were two different diagnostic codes that require separation for a higher evaluation either as an individual disability or to be used in a bilateral factor. So consideration of this SFW to the right lung claim must be deferred until this CUE claim (in not earlier granting this benefit) is decided. See, e.g., Harris v. Derwinski, 1 Vet. App. 180, 183 (1991) (indicating issues are "inextricably intertwined" when they are so closely tied together that a final decision concerning one or more of the claims cannot be rendered until a decision on another. These types of claims should be considered concurrently to avoid piecemeal adjudication of claims with common parameters). See also Ephraim v. Brown, 82 F.3d 399 (Fed. Cir. 1996) and Smith (Daniel) v. Gober, 236 F.3d 1370, 1373 (Fed. Cir. 2001) (Where the facts underlying separate claims are "intimately connected," the interests of judicial economy and avoidance of piecemeal litigation require the claims be adjudicated together.). Consideration of the Veteran's claim of entitlement to SMC based on the loss of use of both lower extremities or the need for A&A is deferred pending resolution of his claims for higher ratings and service connection for his right elbow disability as secondary to his service-connected seborrheic dermatitis, as the claim is inextricably intertwined with the increased-rating and service-connection claims. See Parker v. Brown, 7 Vet. App. 116 (1994); Harris v. Derwinski, 1 Vet. App. 180 (1991). Finally, to ensure completeness of the record, the AMC should obtain all outstanding VA treatment records. See Bell v. Derwinski, 2 Vet. App. 611 (1992). Accordingly, these claims are REMANDED for the following additional development and consideration: 1. After securing any necessary release forms, with full address information, obtain all outstanding records referable to treatment of the Veteran by VA and any other pertinent health care provider. All records and/or responses received should be associated with the claims folder. If any VA or private records sought are not obtained, notify the Veteran and his representative of the records that were not obtained, explain the efforts taken to obtain them, and describe further action to be taken. 38 C.F.R. § 3.159(c) and (e). 2. Upon receipt of all additional records, schedule another VA compensation examination to ascertain the severity of the Veteran's service- connected seborrheic dermatitis (so skin condition), preferably during a time when it is symptomatic or flaring up. The claims file, including a copy of this remand, must be made available to and reviewed by the examiner. All indicated tests and studies should be accomplished, and clinical findings reported in detail. The examiner must provide a detailed review of the Veteran's history, current complaints, and the nature and extent of his seborrheic dermatitis. In addition to any other information provided pursuant to the examination worksheet, the examiner must provide an opinion as to whether the dermatitis during a flare- up covers more than 40 percent of the Veteran's entire body or more than 40 percent of exposed areas affected. The examiner must also address whether the disorder has required systemic therapy such as corticosteroids or other immunosuppressive drugs for any duration in any of the 12-month periods. If so, the examiner must provide the total duration of any such treatment, and if said duration totaled more than six weeks the examiner must state whether the treatment was constant or near-constant in any of the 12-month periods. In all conclusions, the examiner must identify and explain the medical basis or bases, with identification of the evidence of record supporting the finding. If the examiner finds that he/she must resort to mere speculation to render the requested opinion, then he/she must state what reasons, with specificity, preclude a sufficiently definitive response. 3. Also schedule a VA compensation examination to determine the nature and etiology of the Veteran's claimed right elbow disability. The examination should include any necessary diagnostic testing or evaluation. A complete rationale should be provided for all opinions expressed. Based on a physical examination and comprehensive review of the claims file, the examiner is first asked to confirm the Veteran has a right elbow disability. If confirmed he does, then specify the diagnosis. Then indicate the likelihood (very likely, as likely as not, or unlikely) the right elbow disability is: (a) proximately due to or chronically aggravated by the Veteran's service- connected seborrheic dermatitis, psoriatic arthritis of the hands, or any other service-connected disability; or (b) otherwise directly related to injury or disease incurred or aggravated during his service. 4. As well, the Veteran should be afforded an examination of all muscles surrounding his left ankle, left knee, right knee, and left upper extremity of the elbow. The examiner should provide an opinion as to whether there is muscle injury from the RFBs and, if so, what specific muscle groups. If atrophy of a muscle group is present, the examiner should explain the etiology of that atrophy, that is, whether there is actual injury to the muscle or whether the atrophy results from disuse or other cause. To the extent possible, the examiner should identify the locations of the RFBs assigning them to muscle groups (MGs). The examiner should provide an opinion as to whether there is injury to MG X (intrinsic muscles of the foot). The examiner should provide an opinion as to whether there is injury to MG XI (propulsion, plantar flexion of foot). The examiner should provide an opinion as to whether there is injury to MG XII (dorsiflexion of the foot) The examiner should provide an opinion as to whether there is injury to MG XIII (hip and flexion of knee) The examiner should provide an opinion as to whether there is injury to MG XIV (extension of knee) The examiner should provide an opinion as to whether there is injury to MG XV (adduction of hip and flexion of knee) The examiner should provide an opinion as to whether there is any other connective tissue injury that is separate from any muscle injury described in the examination report. All pertinent symptomatology and findings should be reported in detail. All indicated diagnostic tests and studies should be accomplished. 5. Once each report of examination is complete, they should be reviewed to ensure they contain the required responses to the questions posed. If any question has not been answered, the additional information should be obtained. 38 C.F.R. § 4.2. 6. Then readjudicate these remaining claims in light of this and all other additional evidence. For any claim that is not granted to the Veteran's satisfaction, send him and his representative an SSOC and give them an opportunity to respond to it before returning the file to the Board for further appellate consideration of all remaining claims. The Veteran has the right to submit additional evidence and argument concerning these claims the Board are remanding. Kutscherousky v. West, 12 Vet. App. 369 (1999). These claims must be afforded expeditious treatment. The law requires that all claims that are remanded by the Board of Veterans' Appeals or by the United States Court of Appeals for Veterans Claims for additional development or other appropriate action must be handled in an expeditious manner. See 38 U.S.C.A. §§ 5109B, 7112 (West Supp. 2012). ______________________________________________ KEITH W. ALLEN Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
