Freeman, Associate Counsel INTRODUCTION The veteran served on active duty from April 1968 to August 1971. This matter comes before the Board of Veterans' Appeals (Board) on appeal from several rating decisions of the RO in Lincoln, Nebraska. A January 2006 rating decision denied service connection for tinnitus and residuals of a right eye injury and granted service connection for the loss of the left great toenail, assigning a noncompensable rating. The issue of an initial rating in excess of 50 percent for PTSD arises from the grant of service connection in a February 2006 rating decision. The issue of an initial rating in excess of 20 percent for degenerative disc disease arises from the grant of service connection in a June 2006 rating decision. The issue of TDIU arises from an October 2006 rating decision denying entitlement. Finally, the issues of initial ratings in excess of 10 percent for radiculopathy of each leg and increased ratings for onychomyocosis and tinea pedis and chronic obstructive pulmonary disease with chronic bronchitis arise from an April 2007 rating decision. Many of these issues have been before the Board previously. The issues of increased ratings for COPD and onychomyocosis were previously denied in March 2005 and April 2000, respectively. The veteran did appeal to U.S. Court of Appeals for Veterans Claims, but then abandoned the issues in January 2006 and March 2001, respectively. The veteran previously appealed the issue of service connection for degenerative disc disease of the lumbar spine, which was remanded by the Board in March 2005. The June 2006 grant of service connection satisfied this appeal in full and the issue of an increased initial rating is a new and separate appeal. See AB v. Brown, 6 Vet. App. 35, 39 (1993). The claim for an increased rating for COPD and the claim for entitlement to a TDIU are addressed in the REMAND portion of the decision below and are REMANDED to the RO via the Appeals Management Center (AMC), in Washington, DC. FINDINGS OF FACT 1. The evidence on file fails to establish that tinnitus is related to a disease or injury in service. 2. The evidence on file fails to establish that any current right eye disability is related to a disease or injury in service. 3. The veteran does not have a currently diagnosed sleep disorder disability. 4. The veteran's service-connected degenerative disc disease of the lumbar spine with stenosis has been manifested by limitation of motion which is not "severe," forward flexion that exceeds 30 degrees, and flare ups, with no prescribed bedrest, and no neurological functional impairment. 5. The veteran's service-connected peripheral neuropathy of the right leg has not been manifested by more than "mild" symptoms at any time during the period on appeal. 6. The veteran's service-connected peripheral neuropathy of the left leg has not been manifested by more than "mild" symptoms at any time during the period on appeal. 7. The veteran's service-connected PTSD has been manifested by moderate symptoms of avoidance, nightmares, depression, flashbacks without hallucination, delusions, impaired impulse control, episodes of violent, or impairment in the ability to maintain himself or perform the activities of daily living. 8. The veteran's service-connected removal of the left great toenail has not been manifested by more than "mild" functional impairment at any time. 9. The veteran's tinea pedis and onychomyocosis are confined to an area which is not exposed, are not at least 20 percent of the veteran's entire body, and have not required corticosteroid or immunosuppressive drug treatment at any time. CONCLUSIONS OF LAW 1. The veteran's tinnitus was not incurred in or aggravated by active service. 38 U.S.C.A. §§ 1110, 5107 (West 2002); 38 C.F.R. §§ 3.303, 3.304 (2007). 2. A right eye disability was not incurred in or aggravated by active service. 38 U.S.C.A. §§ 1110, 5107 (West 2002); 38 C.F.R. §§ 3.303, 3.304 (2007). 3. A sleep disorder was not incurred in or as a result of the veteran's active duty service and it is not proximately due to or the result of a service-connected disability. 38 U.S.C.A. §§ 1110, 5107 (West 2002); 38 C.F.R. §§ 3.102, 3.303, 3.310 (2007). 4. The criteria for an initial evaluation greater than 20 percent for degenerative disc disease of the lumbar spine with stenosis are not met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. § 4.71a, Diagnostic Code 5293 (2002); 38 C.F.R. § 4.71a, Diagnostic Code 5243 (2007). 5. The criteria for an initial evaluation greater than 10 percent for peripheral neuropathy of the right leg are not met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. § 4.124a, Diagnostic Code 8521 (2007). 6. The criteria for an initial evaluation greater than 10 percent for peripheral neuropathy of the left leg are not met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. § 4.124a, Diagnostic Code 8521 (2007). 7. The criteria for an initial evaluation greater than 50 percent for PTSD are not met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. § 4.130, Diagnostic Code 9411 (2007). 8. The criteria for an initial compensable evaluation for loss of the left great toenail are not met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. § 4.71a, Diagnostic Code 5299- 5284 (2007). 9. The criteria for a rating in excess of 10 percent for onychomycosis of both feet have not been met. 38 U.S.C.A. §§ 1155; 38 C.F.R. § 4.118, DC 7813 (2007). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS The Board has thoroughly reviewed all the evidence in the veteran's claims folders, and has an obligation to provide reasons and bases supporting this decision. See Gonzales v. West, 218 F.3d 1378, 1380-81 (Fed. Cir. 2000) (the Board must review the entire record, but does not have to discuss each piece of evidence in detail). The analysis below focuses on the most salient and relevant evidence and on what this evidence shows, or fails to show, on the claims. The veteran must not assume that the Board has overlooked pieces of evidence that are not explicitly discussed herein. See Timberlake v. Gober, 14 Vet. App. 122 (2000) (the law requires only that the Board address its reasons for rejecting evidence favorable to the veteran). The Board must assess the credibility and weight of all evidence, including the medical evidence, to determine its probative value, accounting for evidence which it finds to be persuasive or unpersuasive, and providing reasons for rejecting any evidence favorable to the claimant. Equal weight is not accorded to each piece of evidence contained in the record; every item of evidence does not have the same probative value. When all the evidence is assembled, VA is responsible for determining whether the evidence supports the claim or is in relative equipoise, with the appellant prevailing in either event, or whether a preponderance of the evidence is against a claim, in which case, the claim is denied. Gilbert v. Derwinski, 1 Vet. App. 49 (1990). I. Veterans Claims Assistance Act With respect to the veteran's claims, VA has met all statutory and regulatory notice and duty to assist provisions. See 38 U.S.C.A. §§ 5100, 5102, 5103, 5103A, 5106, 5107, 5126; 38 C.F.R. §§ 3.102, 3.156(a), 3.159, 3.326. Under the VCAA, when VA receives a complete or substantially complete application for benefits, it is required to notify the claimant and his representative, if any, of any information and medical or lay evidence that is necessary to substantiate the claim. 38 U.S.C.A. § 5103(a) (West 2002); 38 C.F.R. § 3.159(b) (2007); Quartuccio v. Principi, 16 Vet. App. 183 (2002). In Pelegrini v. Principi, 18 Vet. App. 112, 120-21 (2004) (Pelegrini II), the United States Court of Appeals for Veterans Claims (Court) held that VA must inform the claimant of any information and evidence not of record (1) that is necessary to substantiate the claim; (2) that VA will seek to provide; (3) that the claimant is expected to provide; and (4) request that the claimant provide any evidence in his possession that pertains to the claim. Prior to initial adjudication of the veteran's claim, a letter dated in October 2004 fully satisfied the duty to notify provisions for the veteran's tinnitus and right eye claims. 38 U.S.C.A. § 5103(a); 38 C.F.R. § 3.159(b)(1); Quartuccio, at 187. A January 2007 letter satisfied the notice provisions on the sleep disorder claim. See id. The veteran was aware that it was ultimately his responsibility to give VA any evidence pertaining to the claims. The October 2004 and January 2007 letters told him to provide any relevant evidence in his possession. See Pelegrini II, at 120-121. Since the Board has concluded that the preponderance of the evidence is against the claims for service connection, any questions as to the appropriate disability rating or effective date to be assigned are rendered moot, and no further notice is needed. See Dingess v. Nicholson, 19 Vet. App. 473 (2006). The U.S. Court of Appeals for Veterans Claims (Court) recently held that "the statutory scheme contemplates that once a decision awarding service connection, a disability rating, and an effective date has been made, § 5103(a) notice has served its purpose, and its application is no longer required because the claim has already been substantiated." Dingess v. Nicholson, 19 Vet. App. 473, 490 (2006). In this case, the veteran's claims for service connection for his left great toe, PTSD, back, and bilateral radiculopathy were granted, disability ratings and effective dates assigned, in January 2005, February and June 2006 and April 2007 decisions of the RO. VA's duty to notify under 38 U.S.C.A. § 5103(a) is discharged. See Sutton v. Nicholson, 20 Vet. App. 419 (2006). Accordingly, the Board concludes that any error in failing to provide adequate pre-adjudicative notice under 38 U.S.C.A. § 5103(a) was harmless. For the claim for an increased rating for onychomyocosis, the second, third and fourth elements of Pelegrini II notice were satisfied in a January 2007 letter. The U.S. Court of Appeals for Veterans Claims (Court) recently ruled that, in claims for increased ratings not arising from grants of service connection, the duty to notify requirements for an increased-compensation claim, section 5103(a) compliant notice must meet the following four part test: (1) that the Secretary notify the claimant that, to substantiate a claim, the claimant must provide, or ask the Secretary to obtain, medical or lay evidence demonstrating a worsening or increase in severity of the disability and the effect that worsening has on the claimant's employment and daily life; (2) if the Diagnostic Code under which the claimant is rated contains criteria necessary for entitlement to a higher disability rating that would not be satisfied by the claimant demonstrating a noticeable worsening or increase in severity of the disability and the effect of that worsening has on the claimant's employment and daily life (such as a specific measurement or test result), the Secretary must provide at least general notice of that requirement to the claimant; (3) the claimant must be notified that, should an increase in disability be found, a disability rating will be determined by applying relevant Diagnostic Codes, which typically provide for a range in severity of a particular disability from noncompensable to as much as 100 percent (depending on the disability involved), based on the nature of the symptoms of the condition for which disability compensation is being sought, their severity and duration, and their impact upon employment and daily life; (4) the notice must also provide examples of the types of medical and lay evidence that the claimant may submit (or ask the Secretary to obtain) that are relevant to establishing entitlement to increased compensation, e.g., competent lay statements describing symptoms, medical and hospitalization records, medical statements, employer statements, job application rejections, and any other evidence showing an increase in the disability or exceptional circumstances relating to the disability. Vazquez-Flores v. Peake, 22 Vet. App. 37 (2008). For the following reasons, the Board finds that the elements of the Vazquez-Flores test have either been met or that any error is not prejudicial. Preliminarily, the Board notes that the notice provided in this case was issued prior to the decision in Vazquez-Flores. As such it does not take the form prescribed in that case. Failure to provide pre-adjudicative notice of any of the necessary duty to notify elements is presumed to create prejudicial error. Sanders v. Nicholson, 487 F.3d 881 (2007). The Secretary has the burden to show that this error was not prejudicial to the veteran. Id., at 889. Lack of prejudicial harm may be shown in three ways: (1) that any defect was cured by actual knowledge on the part of the claimant, (2) that a reasonable person could be expected to understand from the notice what was needed, or (3) that a benefit could not have been awarded as a matter of law. Id., at 887; see also Mayfield v. Nicholson, 19 Vet. App. 103, (2005), rev'd on other grounds, Mayfield v. Nicholson, 444 F.3d 1328 (Fed. Cir. 2006). The Federal Circuit indicated that this was not an exclusive list of ways that error may be shown to be non prejudicial. See Sanders, at 889. In order for the Court to be persuaded that no prejudice resulted from a notice error, the record must demonstrate that, despite the error, the adjudication was nevertheless essentially fair. See also Dunlap v. Nicholson, 21 Vet. App. 112, 118 (2007). Prior to the initial adjudication of the claim, the RO sent the veteran a May 2005 letter, which requested that the veteran provide evidence describing how his disability had worsened. In addition, the veteran was questioned about the effect that worsening has on his employment and daily life during the course of the 2007 VA examination performed in association with this claim. The Board finds that the notice given, the questions directly asked and the responses provided by the veteran both at interview and in his own statements show that he knew that the evidence needed to show that his disability had worsened and what impact that had on his employment and daily life. As the Board finds the veteran had actual knowledge of the requirement, any failure to provide him with adequate notice is not prejudicial. See Sanders, supra. The Board finds that the first criterion is satisfied. See Vazquez-Flores. As to the second element, the Board notes that the veteran is service connected for onychomyocosis and tinea pedis of the feet. Tinea pedis and onychomyocosis fall under Diagnostic Code 7813, Dermatophytosis. See 38 C.F.R. § 4.118 (2007). This is the only Diagnostic Code to rate this disability and it is not cross referenced to any other Codes for the purposes of evaluation. See id. The Diagnostic Code relies on a single measurement or test to establish a higher rating. See id. The veteran was not provided notice of this as required by Vazquez-Flores, supra. The Board concludes, however, that this error was not prejudicial. The RO provided an opportunity to undergo the necessary test in March 2007 and the veteran did so. The veteran has been represented by an attorney for the entire period on appeal and the veteran's representative has submitted direct argument on this issue that will be discussed below. Given the nature of the veteran's claim, that he is represented by an attorney and the fact that the RO scheduled him for an examination in connection with this claim that the veteran underwent, the Board finds that a reasonable person would have known the general requirements necessary to establish a higher rating. The Board finds that any error in failure to provide Vazquez-Flores element two notice is not prejudicial. See Sanders, supra. As to the third element, the January 2007 provided notice to the veteran that a disability rating would be determined by application of the ratings schedule and relevant Diagnostic Codes based on the extent and duration of the signs and symptoms of his disability and their impact on his employment and daily life. See Vazquez-Flores. The Board finds that the third element of Vazquez-Flores is satisfied. See id. As to the fourth element, the 2005 letter did provide notice of the types of evidence, both medical and lay, including employment records, that could be submitted in support of his claim. The Board finds that the fourth element of Vazquez- Flores is satisfied. See id. Since the RO continued the 10 percent disability rating at issue here for the veteran's service-connected onychomyocosis disability, and the Board has concluded that the preponderance of the evidence is against assigning a higher rating, there is no question as to an effective date to be assigned, and no further notice is needed. See Dingess v. Nicholson, 19 Vet. App. 473 (2006). The Board also concludes VA's duty to assist has been satisfied. The veteran's service medical records and VA medical records are in the file. Private medical records identified by the veteran have been obtained, to the extent possible. In October 2006, the veteran submitted a letter from the Social Security Administration (SSA) notifying him that he did not qualify for benefits under the disability insurance program. The letter states that the veteran's claim failed for lack of a qualifying work history sufficient to entitle him to benefits, regardless of his disability status. Such a denial indicates that the veteran was denied in the first step of the sequential evaluation process. See generally 20 C.F.R. § 404.1520 (2007). The letter also states that the veteran also failed to qualify for any other benefits, i.e. supplemental security income, based on the application he filed. See generally 20 C.F.R. § 416.920 (2007). A denial in the first step means that the SSA did not proceed to gather evidence about the veteran's disabilities. See 20 C.F.R. §§ 404.1520, 416.920. The veteran has been notified, as discussed above, that he should submit any relevant records in his possession to VA. The Board finds that, because any relevant records that the SSA might possess are also in the possession of the veteran and because he has not referenced outstanding records that he wanted VA to obtain or that he felt were relevant to the claims, any error in failing to obtain SSA records is harmless. See 38 U.S.C.A. § 5107 (a claimant has the responsibility to support a claim for benefits); see also Hyatt v. Nicholson, 21 Vet. App. 390 (2007). The duty to assist also includes providing a medical examination or obtaining a medical opinion when such is necessary to make a decision on the claim, as defined by law. The veteran was afforded a March 2004 VA examination to evaluate his tinnitus and determine whether he had a disability related to service. As will be discussed below, the examiner found that the veteran's tinnitus was not at least as likely as not related to service. As the Board finds that the preponderance of the evidence is against a relationship between the veteran's tinnitus and service, further examination or opinion is not needed on the claim. The veteran was afforded a November 2004 VA examination to evaluate his right eye and determine whether he had a disability related to his inservice right eye injury. As will be discussed below, the examiner found deficits in the right eye but concluded that did not have any residuals secondary to his injury. As the Board finds that the preponderance of the evidence is against a relationship between a current right eye disability and the inservice injury, further examination or opinion is not needed on the claim. The veteran was afforded March and April 2007 medical examinations to obtain an opinion as to whether the veteran had a sleep disability. Further examination or opinion is not needed on the sleep disorder claim because, at a minimum, there is no persuasive and competent evidence that the claimed condition exists as a distinct, medically diagnosable disability. This is discussed in more detail below. The duty to assist includes, when appropriate, the duty to conduct a thorough and contemporaneous examination of the veteran. Green v. Derwinski, 1 Vet. App. 121 (1991). In addition, where the evidence of record does not reflect the current state of the veteran's disability, a VA examination must be conducted. Schafrath v. Derwinski, 1 Vet. App. 589 (1991); 38 C.F.R. § 3.327(a) (2007). The RO provided the veteran appropriate VA examinations for PTSD in December 2005 and in March 2007 for his spine disability, neuropathy of each leg, and feet. There is no objective evidence indicating that there has been a material change in the severity of the veteran's service-connected disorders since he was last examined. 38 C.F.R. § 3.327(a). The duty to assist does not require that a claim be remanded solely because of the passage of time since an otherwise adequate VA examination was conducted. VAOPGCPREC 11-95. The 2005 and 2007 VA examination reports are thorough and supported by VA outpatient treatment records. The examination in this case is adequate upon which to base a decision. As there is no indication that any failure on the part of VA to provide additional notice or assistance reasonably affects the outcome of this case, the Board finds that any such failure is harmless. See Mayfield v. Nicholson, 19 Vet. App. 103 (2005), rev'd on other grounds, Mayfield v. Nicholson, 444 F.3d 1328 (Fed. Cir. 2006). II. Service Connection Service connection may be established for a disability resulting from disease or injury incurred in or aggravated by active service. 38 U.S.C.A. § 1110. For the showing of chronic disease in service there is required a combination of manifestations sufficient to identify the disease entity, and sufficient observation to establish chronicity at the time. 38 C.F.R. § 3.303(b). If chronicity in service is not established, a showing of continuity of symptoms after discharge is required to support the claim. Id. Service connection may be granted for any disease diagnosed after discharge, when all of the evidence establishes that the disease was incurred in service. 38 C.F.R. § 3.303(d). In order to establish service connection for the claimed disorder, there must be (1) medical evidence of a current disability; (2) medical, or in certain circumstances, lay evidence of in-service incurrence or aggravation of a disease or injury; and (3) medical evidence of a nexus between the claimed in-service disease or injury and the current disability. See Hickson v. West, 12 Vet. App. 247, 253 (1999). a. Tinnitus The veteran contends that he has tinnitus as a result of service. For the reasons that follow, the Board concludes that service connection is not warranted. The veteran was seen at a March 2004 audiological examination where he reported tinnitus since service. The audiologist diagnosed tinnitus in both ears. The Board is satisfied with the evidence of a current disability. The Board finds, however, that the veteran did not incur the disability in service. The Board acknowledges that the veteran is competent to give evidence about what he experienced; for example, he is competent to report that he experiences certain symptoms. See, e.g., Layno v. Brown, 6 Vet. App. 465 (1994). Competency, however, must be distinguished from weight and credibility, which are factual determinations going to the probative value of the evidence. See Rucker v. Brown, 10 Vet. App. 67, 74 (1997). Review of the claims file reveals numerous instances of the veteran contradicting his own claim. The veteran's service medical records are silent for any complaint or diagnosis of tinnitus. While the veteran did have noise exposure and has been service connected for hearing loss, there is no evidence to show that he had tinnitus while inservice. The veteran has maintained during the course of the instant appeal that he has had tinnitus since he separated from service in 1971. During a January 1999 VA audiological examination, a February 1999 VA audiology clinic visit and an April 1999 VA audiological examination, he denied having tinnitus. In short, at all times prior to the instant appeal, he has denied the existence of the disability. The Board finds that the veteran's allegations that the tinnitus began in service are not credible. The March 2004 VA examination report contains an opinion that the veteran's tinnitus is not at least as likely as not related to service. This is the sole competent medical opinion of record. The Board finds that the preponderance of the evidence is against either incurrence of tinnitus inservice or a relationship between the veteran's tinnitus and any incident of service. As the Board finds that the veteran's statements regarding inservice incurrence are incredible and his service medical records are devoid of mention of tinnitus, service connection is not available based on continuity of symptomatology. See 38 C.F.R. § 3.303. Service connection must also fail on the grounds of Hickson, supra. As such, the Board finds that the preponderance of the evidence is against the veteran's claim. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). b. Residuals of a Right Eye Injury The veteran contends that he has a right eye disability as a result of an injury during service. For the reasons that follow, the Board concludes that service connection is not warranted. The veteran was seen at a November 2004 VA examination. The veteran stated that he had a foreign body sensation in his right eye. He had undergone cataract surgery in the right eye in November 2003, with intraocular lens placement. The veteran's visual acuity with glasses after his surgery was 20/30 near and 20/60 distance. The Board concedes that the veteran been diagnosed with a cataract disability, status post surgery. The veteran's service medical records do indicate that he was treated for a right eye injury. In October 1968, the veteran was treated during service for a penetrating glass injury of the eye. His records indicate that the glass was removed and no complications or sequelae are mentioned. The claim must fail, however, because the medical evidence is against a relationship between the right eye cataract and the inservice injury. The examiner at his November 2004 VA examination indicated that the cataract was not the result of the glass injury. He further indicated that the veteran had no residual deficits secondary to the injury that could be found on examination. The Board acknowledges that the veteran is competent to give evidence about what he experienced; for example, he is competent to report that he experiences certain symptoms. See, e.g., Layno v. Brown, 6 Vet. App. 465 (1994). Competency, however, must be distinguished from weight and credibility, which are factual determinations going to the probative value of the evidence. See Rucker v. Brown, 10 Vet. App. 67, 74 (1997). He is not, however, competent to diagnose any medical disorder or render an opinion as to the cause or etiology of any current disorder because he does not have the requisite medical knowledge or training. See Espiritu v. Derwinski, 2 Vet. App. 492 (1992). The competent medical evidence shows that the veteran has no deficits related to the right eye injury which occurred during service. He has offered no medical evidence of his own to counter this, and it is uncontested throughout the remaining VA treatment records. The Board finds that the preponderance of the evidence is against a relationship between the veteran's current right eye disability and his inservice injury. The Board concludes that service connection must be denied. See 38 C.F.R. § 3.303, supra. As such, the Board finds that the preponderance of the evidence is against the veteran's claim. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). c. Sleep Disorder The primary basis of the veteran's claim is that service connection should be granted for the veteran's sleep disorder as being caused by the service-connected spine disability. In addition to service connection on a direct basis as discussed above, service connection may be established on a secondary basis for a disability, shown to be proximately due to, or the result of, a service-connected disease or injury. 38 C.F.R. § 3.310(a). Establishing service connection on a secondary basis requires evidence sufficient to show (1) that a current disability exists and (2) that the current disability was either (a) caused by or (b) aggravated by a service-connected disability. 38 C.F.R. § 3.310(a); Allen v. Brown, 7 Vet. App. 439 (1995) (en banc). For service connection on either direct or secondary bases, diagnosis of a current disability is required. See 38 C.F.R. §§ 3.303, 3.310. The veteran was examined for sleep disturbances in April 2007. The examiner indicated that the veteran reported difficulty sleeping most nights. Following examination, the examiner stated that the veteran did not have a diagnosable sleep disorder, as the sleep disturbances were an aspect of PTSD and he did not have evidence of insomnia, a circadian sleep rhythm disorder, a nightmare or sleep terror disorder, a substance induced disorder or insomnia related to a medical disorder. The Board acknowledges that the veteran is competent to give evidence about what he experienced; for example, he is competent to report that he experiences difficulty sleeping. See, e.g., Layno v. Brown, 6 Vet. App. 465 (1994). He is not, however, competent to diagnose any medical disorder or render an opinion as to the cause or etiology of any current disorder because he does not have the requisite medical knowledge or training. See Espiritu v. Derwinski, 2 Vet. App. 492 (1992). The remaining evidence of record does not reveal a diagnosis of a sleep disorder. The Board finds that the preponderance of the evidence shows that the veteran does not have a current diagnosis of a sleep disorder. The Board concludes that service connection is not warranted on either a direct or secondary basis. See Hickson, supra; see also Allen, supra. As such, the Board finds that the preponderance of the evidence is against the veteran's claim. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). III. Increased Ratings The veteran contends that he is entitled to higher ratings for his various service connected disabilities. For the reasons that follow, the Board concludes that an increased rating is not warranted. Disability evaluations are determined by evaluating the extent to which a veteran's service-connected disability adversely affects his or her ability to function under the ordinary conditions of daily life, including employment, by comparing his or her symptomatology with the criteria set forth in the Schedule for Rating Disabilities. The percentage ratings represent as far as can practicably be determined the average impairment in earning capacity resulting from such diseases and injuries and the residual conditions in civilian occupations. Generally, the degree of disabilities specified are considered adequate to compensate for considerable loss of working time from exacerbation or illness proportionate to the severity of the several grades of disability. 38 U.S.C.A. § 1155 (West 2002 & Supp. 2007); 38 C.F.R. § 4.1 (2007). Separate diagnostic codes identify the various disabilities and the criteria for specific ratings. If two disability evaluations are potentially applicable, the higher evaluation will be assigned to the disability picture that more nearly approximates the criteria required for that rating. Otherwise, the lower rating will be assigned. 38 C.F.R. § 4.7. Any reasonable doubt regarding the degree of disability will be resolved in favor of the veteran. 38 C.F.R. § 4.3. However, the evaluation of the same disability under various diagnoses, known as pyramiding, is to be avoided. 38 C.F.R. § 4.14 (2007). Where entitlement to compensation has already been established and an increase in the disability rating is at issue, it is the present level of disability that is of primary concern. See Francisco v. Brown, 7 Vet. App. 55, 58 (1994). Consistent with the facts found, the rating may be higher or lower for segments of the time under review on appeal, i.e., the rating may be "staged." Fenderson v. West, 12 Vet. App. 119 (1999); see also Hart v. Mansfield, 21 Vet. App. 505 (2007). a. Spine The veteran is service connected for degenerative disc disease of the lumbar spine, status post a lumbar laminectomy. The veteran contends that he is entitled to an initial rating in excess of 20 percent. For the reasons that follow, the Board concludes that an initial rating in excess of 20 percent is not warranted. During the pendency of this claim, the criteria for rating spine disabilities were revised (effective September 23, 2002 and September 26, 2003). The Board will evaluate the veteran's claim under both the criteria in the VA Schedule for Rating Disabilities in effect at the time of his filing and the current regulations in order to ascertain which version would accord him the highest rating. According to VAOPGCPREC 7-2003 (Nov. 19, 2003), in Kuzma v. Principi, 341 F.3d 1327 (Fed. Cir. 2003), the Federal Circuit overruled Karnas v. Derwinski, 1 Vet. App. 308 (1991), to the extent it conflicts with the precedents of the United States Supreme Court (Supreme Court) and the Federal Circuit. Karnas is inconsistent with Supreme Court and Federal Circuit precedent insofar as Karnas provides that, when a statute or regulation changes while a claim is pending before VA or a court, whichever version of the statute or regulation is most favorable to the claimant will govern unless the statute or regulation clearly specifies otherwise. Accordingly, the rule adopted in Karnas no longer applies in determining whether a new statute or regulation applies to a pending claim. Id. However, none of the above cases or General Counsel opinions prohibits the application of a prior regulation to the period on or after the effective date of a new regulation. Thus, the rule that the veteran is entitled to the most favorable of the versions of a regulation that was revised during his appeal allows application of the prior versions of the applicable diagnostic codes at 38 C.F.R. § 4.71a to the period on or after the effective dates of the new regulations. The RO considered all these changes in adjudicating the veteran's claim. Therefore, there is no prejudice to the veteran by this Board decision. See Bernard v. Brown, 4 Vet. App. 384 (1993). Effective September 23, 2002, VA revised the criteria for diagnosing and evaluating intervertebral disc syndrome. 67 Fed. Reg. 54,345 (Aug. 22, 2002). When VA revised the criteria for evaluating general diseases and injuries of the spine effective September 26, 2003, as discussed above, VA also reiterated the changes to Diagnostic Code (DC) 5293 (now reclassified as Diagnostic Code 5243) for intervertebral disc syndrome. In determining whether the veteran is entitled to a higher rating, the Board must consider (1) whether an increased rating is warranted under the "old" criteria at any time; (2) whether an increased rating is warranted under the "new" criteria for intervertebral disc syndrome at any time on or after September 23, 2002; and (3) whether an increased rating is warranted under the "new" criteria for other disabilities of the thoracolumbar spine at any time on or after September 26, 2003. The effective date of any rating assigned under the revised schedular criteria may not be earlier than the effective date of that change; the Board must apply only the earlier version of the regulation for the period prior to the effective date of change. See VAOPGCPREC 3-2000; 38 U.S.C.A. § 5110(g) (West 2002) (where compensation is awarded pursuant to any Act or administrative issue, the effective date of such award or increase shall be fixed in accordance with the facts found but shall not be earlier than the effective date of the Act or administrative issue). The currently assigned 20 percent rating would have been assigned for moderate intervertebral disc syndrome under the old Diagnostic Code 5293. A 40 percent rating could be assigned under the old criteria for intervertebral disc syndrome that is severely disabling with recurring attacks and intermittent relief. 38 C.F.R. § 4.71a, Diagnostic Code 5293 (2002). Under that code, the maximum schedular rating of 60 percent is assigned for intervertebral disc disease which is pronounced with persistent symptoms compatible with sciatic neuropathy with characteristic pain and demonstrable muscle spasm, absent ankle jerk, or other neurological findings appropriate to site of diseased disc, little intermittent relief. A precedent opinion of VA's Office of General Counsel, VAOPGCPREC 36-97 (1997), held that Diagnostic Code 5293 involves loss of range of motion because the nerve defects and resulting pain associated with injury to the sciatic nerve may cause limitation of motion of the cervical, thoracic, or lumbar vertebrae. In considering the evidence of record, the Board notes that the veteran does have diagnosed neurological complications in his lower extremities, appropriate to the site of the diseased disc. The veteran began reporting daily paresthesias in his lateral thighs at his April 2006 VA examination. These have been separately service connected as will be discussed below. In the period prior to the grant of service connection for neuropathy as a separate disability, the veteran did not have symptoms of demonstrable muscle spasm, absent ankle jerk, or any kind of loss of sensory, reflex or motor function. In February 2001, the veteran denied radicular symptoms. The Board finds that the veteran's degenerative disc disease symptoms are not "severe" as contemplated by DC 5293; a higher initial rating is not warranted under this DC. See 38 C.F.R. § 4.71a (2002). The revisions to 38 C.F.R. § 4.71a, Diagnostic Code 5293, for rating intervertebral disc syndrome provide that preoperative or postoperative intervertebral disc syndrome is to be 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. 38 C.F.R. § 4.71a, Diagnostic Code 5293 (2003). Effective September 26, 2003, intervertebral disc syndrome was assigned a new diagnostic code number (5243), and the instruction with respect to the separate evaluation of neurologic and orthopedic manifestations was re-worded and moved to Note 1, following the General Rating Formula for Diseases and Injuries of the Spine, and the above-mentioned instruction was re-phrased to state that intervertebral disc syndrome (pre-operatively or post-operatively) is to be evaluated either under the General Rating Formula for Diseases and Injuries of the Spine or under the Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes, whichever method results in the higher evaluation when all disabilities are combined under section 4.25. However, these revisions were intended to be clarifying and non-substantive in nature. See Schedule for Rating Disabilities; The Spine, 67 Fed. Reg. 56,509, 56,510 (Sept. 4, 2002) (indicating that the then-proposed amendment "would make editorial changes", but would not "represent any substantive change to the recently adopted evaluation criteria for intervertebral disc syndrome"). (The Board notes that some of the Notes were inadvertently omitted when Diagnostic Code 5293 was re-published as Diagnostic Code 5243 in August 2003; however, this has since been corrected. See Schedule for Rating Disabilities; The Spine; Correction, 69 Fed. Reg. 32,449 (June 10, 2004)). With regard to the first method of evaluation (total duration of incapacitating episodes over the past 12 months), the new criteria provide that a 10 percent evaluation is warranted if intervertebral disc syndrome is manifested by incapacitating episodes having a total duration of at least one week but less than two weeks during the past 12 months. A 20 percent evaluation is warranted if incapacitating episodes have a total duration of at least two weeks but less than four weeks; a 40 percent rating is warranted if the total duration is at least four weeks but less than six weeks; and a 60 percent rating is warranted if the total duration is at least six weeks. See 38 C.F.R. § 4.71a, DC 5293 (2003). For purposes of evaluations under 5293, an incapacitating episode is a period of acute signs and symptoms due to intervertebral disc syndrome that requires bed rest prescribed by a physician and treatment by a physician. The term "chronic orthopedic and neurologic manifestations" were defined as "orthopedic and neurologic signs and symptoms resulting from intervertebral disc syndrome that are present constantly, or nearly so". 38 C.F.R. § 4.71a, Diagnostic Code 5293 (2003), Note (1). (As noted previously, effective from September 26, 2003, the instruction with respect to the separate evaluation of neurologic and orthopedic manifestations was re-worded and moved to Note 1, following the General Rating Formula for Diseases and Injuries of the Spine; however, the change was intended to be clarifying and non-substantive in nature.) The Board notes that the veteran's treatment records show no instance of physician prescribed bedrest. In March 2004, the veteran reported that, since he stopped working in 1996, he has had few, if any, flare ups. He did report that he had flare ups at his April 2006 VA examination. The veteran's VA treatment records do not show any prescribed bedrest. As such, the Board concludes that the criteria for an initial rating in excess of 20 percent are not met under the incapacitating episode criteria of DC 5243. See 38 C.F.R. § 4.71a (2007). The Board has also considered the application of other Diagnostic Codes. As with the ratings for intervertebral disc syndrome, the criteria rating other back disabilities were revised. Effective September 26, 2003, a General Ratings Formula was instituted to evaluate back disabilities. As above, the Board has considered both the prior and current regulations. See VAOPGCPREC 3-2000; 38 U.S.C.A. § 5110(g) (West 2002). Under 38 C.F.R. § 4.71a, DC 5292 (as in effect prior to September 26, 2003), a 20 percent rating is warranted where the limitation of motion in the lumbar spine is "moderate," and a 40 percent evaluation is assigned for "severe" limitation of motion. The Board observes that the words "moderate" and "severe" are not defined in the VA rating schedule. Rather than applying a mechanical formula, the Board must evaluate all of the evidence to the end that its decisions are "equitable and just." 38 C.F.R. § 4.6 (2007). Disabilities of the spine, excepting degenerative disc disease, are currently rated under the General Rating Formula for Diseases and Injuries of the Spine. See 38 C.F.R. § 4.71a, DC 5237-5243. Under the Formula, a 20 percent evaluation is assigned for forward flexion of the thoracolumbar spine greater than 20 degrees but not greater than 60 degrees; or, the combined range of motion of the thoracolumbar spine not greater than 120 degrees; or, muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis. Id. A 40 percent evaluation requires forward flexion of the thoracolumbar spine 30 degrees or less; or, favorable ankylosis of the entire thoracolumbar spine. Id. A 50 percent evaluation requires unfavorable ankylosis of the entire thoracolumbar spine. Id. A 100 percent evaluation is warranted where unfavorable ankylosis of the entire spine is demonstrated. Id. These evaluations are for application 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. Id. For VA compensation purposes, normal forward flexion of the thoracolumbar spine is 0 to 90 degrees, extension is 0 to 30 degrees, left and right lateral flexion are 0 to 30 degrees, and left and right lateral rotation are 0 to 30 degrees. 68 Fed. Reg. 51454, 51456 (codified at 38 C.F.R. § 4.71a, Diagnostic Codes 5235 to 5243, Note (2)). Although the criteria under Diagnostic Code 5292 were less defined than the current criteria and numerical ranges of motion were not provided in the prior rating criteria, guidance can be obtained from the amended regulations. In adopting specific ranges of motion to define what is normal, VA stated that the ranges of motion were based on the American Medical Association Guides to the Evaluation of Permanent Impairment, 2nd ed., (1984), which is the last edition of the Guides that measured range of motion of the spine using a goniometer. See supplementary information, 67 Fed. Reg. 56,509 (Sept. 4, 2002). In other words, even though pre-2003 regulations did not define normal range of motion for the spine, the current definition is based on medical guidelines in existence since 1984, and the Board can consider the current ranges of motion to rating spine disabilities under the old criteria. The earliest records pertinent to this claim do not provide assessments of range of motion. In February 1996, the veteran complained of back pain and he was begun on medication. In 2000 and 2001, the veteran complained of back pain, without radicular symptoms. The veteran received MRI and x-ray studies in April and May 2002 which showed the progression of his disability, but, again, did not provide an assessment of functional loss. At a March 2004 VA examination, the veteran reported fairly persistent pain in his lower back. He denied the use of a brace and he indicated that he did not have significant flare ups as he was unemployed. The veteran reported being able to perform daily duties around the house. On examination, the veteran had forward flexion to 70 degrees with pain starting at 45 degrees, extension to 5 degrees, bilateral lateral flexion to 25 degrees and bilateral rotation to 35 degrees. The veteran performed the rotation test five times with no pain, weakness, fatigue, incoordination or endurance problems. On extension, he reported some mild to moderate pain on the third test, but the veteran had only 5 degrees of extension to begin with; the Board notes that there can be little additional impact. On lateral flexion, the veteran had mild to moderate pain and some mild weakness by the third repetition in each direction. The pain began at about 20 degrees. On forward flexion, the veteran performed three repetitions before quitting due to pain and weakness and some endurance and fatiguing issues. No incoordination was noted. On the third attempt the veteran reached only 55 degrees. The veteran had another VA examination in April 2006. The veteran had mild flattening of the lumbar spine. He had mild spasm, mild guarding and tenderness and moderate pain with motion. He had no atrophy or weakness. The veteran had forward flexion to 70 degrees, with pain beginning at 40 degrees. The veteran had 5 degrees of extension, with pain throughout. He had lateral flexion to 20 degrees bilaterally, with pain at 15 degrees bilaterally. He had lateral rotation to 25 degrees bilaterally, with pain at 15 degrees bilaterally. The veteran had some additional loss of motion on repetitive use due to pain. The veteran reported flare ups of pain when bending, twisting or lifting. The examiner characterized the veteran's impairment as moderate decreased motion and stiffness and mild fatigue, weakness and spasm. Ankylosis was not present. The veteran had an antalgic gait. An October 2006 vascular clinic evaluation notes that the veteran's gait was normal, with no abnormal spinal contour or atrophy. In June 2007, the veteran was provided with an elastic back brace. The Board finds that the criteria for a rating in excess of 20 percent have not been met under either the prior or current range of motion criteria. The veteran has, at no time, had forward flexion limited to 30 degrees. At most, the veteran manifests pain in forward flexion at 45 degrees, leaving half of the range of motion intact. There is no indication of ankylosis. The veteran's overall limitation of motion is part of the criteria for a 20 percent rating, which he already receives. The Board recognizes that the veteran was provided with an elastic back brace in June 2007; however, there is no indication of significant change or progress of the disability. Under both the prior DC 5292 and the current General Ratings Formula, DC 5243, the Board concludes that the criteria for a higher rating have not been met. See 38 C.F.R. § 4.71a (2002, 2007). The Board has considered the remaining DCs for back disabilities. The veteran does not, however, suffer from a vertebral fracture injury, cervical or thoracic disabilities or chronic muscle strain. The Board concludes that the remaining DCs are inapplicable in this case. See 38 C.F.R. § 4.71a (2002, 2003, 2007). Any associated objective neurologic abnormalities, including, but not limited to, bowel or bladder impairment, are separately evaluated under an appropriate Diagnostic Code. Id., at Note (1). The RO has service connected the veteran's neurological complications separately, effective April 21, 2006. Neurological complications were also considered during discussion of the prior intervertebral disc syndrome ratings criteria. There are no additional neurological symptoms. Further consideration is not warranted. In the present case, it should also be noted that when evaluating disabilities of the musculoskeletal system, 38 C.F.R. § 4.40 allows for consideration of functional loss due to pain and weakness causing additional disability beyond that reflected on range of motion measurements. DeLuca v. Brown, 8 Vet. App. 202 (1995). Further, 38 C.F.R. § 4.45 provides that consideration also be given to weakened movement, excess fatigability and incoordination. The Board has given such consideration, by using the range of motion measurements as limited to where pain began, rather than the full extent to which the veteran might move. Even with this additional limitation, the veteran's symptoms did not reach the level needed for a higher rating. The Board concludes that a further increase under DeLuca is not warranted. The Board has considered the possibility of staged ratings. Fenderson; Hart, both supra. The Board, however, concludes that the criteria for a compensable rating have at no time been met. Accordingly, staged ratings are inapplicable. See id. As such, the Board finds that the preponderance of the evidence is against the veteran's spine rating claim. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). b. Radiculopathy of the Legs The veteran contends that he is entitled to an initial rating in excess of 10 percent for neuropathy of each leg. For the reasons that follow, the Board concludes that increased ratings are not warranted. The veteran's bilateral peripheral neuropathy is rated under DC 8521. Diagnostic Code 8521 provides for a 40 percent rating for complete paralysis of the external popliteal nerve (common peroneal) where there is foot drop and slight droop of first phalanges of all toes, cannot dorsiflex the foot, extension (dorsal flexion) of proximal phalanges of toes lost; abduction of foot lost, adduction weakened; anesthesia covers entire dorsum of foot and toes. 38 C.F.R. § 4.124a, Diagnostic Code 8521. A 30 percent evaluation is warranted for severe incomplete paralysis. Id. A 20 percent evaluation is assigned where there is moderate incomplete paralysis and a 10 percent evaluation is warranted for mild incomplete paralysis. Id. The term "incomplete paralysis" indicates impairment of function of a degree substantially less than the type of picture for complete paralysis given for each nerve, whether due to varied level of the nerve lesion or to partial regeneration. When the involvement is wholly sensory, the rating should be for the mild, or, at most, the moderate degree. 38 C.F.R. § 4.124a, Note. The Board finds that the veteran's peripheral neuropathy results in no more than "mild" symptoms. While the veteran does have a diagnosis and complains of paresthesias, thus far the evidence shows that he does not suffer from functional loss as a result of peripheral neuropathy in either leg. At his March 2004 VA examination, the veteran's sharp and dull sensation was intact in thighs, legs and feet. Deep tendon reflexes were 2/4 at the knees. The veteran denied radicular symptoms. At his April 2006 VA examination in association with his spine rating claim, the veteran reported paresthesias of the outer thigh. He had 1+ reflexes at the knee and ankle levels. The veteran also had impaired pinprick and light touch sensation in both lower extremities. The veteran had a comprehensive examination in March 2007 which evaluated his peripheral neuropathy. The veteran's muscle strength, bulk, tone and function were normal. Sensory function was normal to vibration, pain (pin prick), light touch and position sense. Reflexes were 2+ at both the knee and ankle levels. The veteran had normal gait and balance without abnormal movement, tics or tremors. Subsequent to the March 2007 evaluation, the veteran was seen for an April 2007 electromyelogram (EMG). The EMG report indicates that the veteran had chronic neurogenic changes consistent with his previous radiculopathy. Motor conduction and F-wave latency studies of the right peroneal and posterior tibial nerves were within normal limits. Bilateral sural (sensory) nerve conduction studies were within normal limits. The veteran has been diagnosed with claudication of the lower extremities. A May 2005 vascular evaluation found the claudication to be consistent with an ongoing peripheral vascular disease process, atherosclerosis. This conclusion has been confirmed repeatedly. As such, the veteran's claudication is not a part of the neurological complications of his service connected disorders and the Board will not consider it when rating his peripheral neuropathy. The veteran has reported fatiguability and pain in his calves and feet when walking, but these problems have been attributed to his claudication, not his peripheral neuropathy. In sum, the preponderance of the evidence shows that the veteran retains normal motor, reflex and sensory function. The veteran had signs of functional loss in April 2006, but this is the sole occurrence of the diminished reflex and sensation of record. The remaining treatment records show normal functioning both prior to and after the April 2006 examination. As such, the Board finds that the veteran's symptoms are "mild" in degree at all times during the period on appeal. The criteria for initial ratings in excess of 10 percent for peripheral neuropathy of either the left or right leg have not been met at any time. See 38 C.F.R. § 4.124a, DC 8521; see also Fenderson, supra. As such, the Board finds that the preponderance of the evidence is against the veteran's peripheral neuropathy claims. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). c. PTSD The veteran's service-connected PTSD is evaluated as 50 percent disabling under the General Rating Formula for Mental Disorders, 38 C.F.R. § 4.130, Diagnostic Code 9411. Ratings are assigned according to the manifestation of particular symptoms. However, the use of the term "such as" in 38 C.F.R. § 4.130 demonstrates that the symptoms after that phrase are not intended to constitute an exhaustive list, but rather are to serve as examples of the type and degree of the symptoms, or their effects, that would justify a particular rating. Mauerhan v. Principi, 16 Vet. App. 436 (2002). Under the provisions for rating psychiatric disorders, a 50 percent disability rating requires evidence of the following: Occupational and social impairment with reduced reliability and productivity due to such symptoms as: flattened affect; circumstantial, circumlocutory, or stereotyped speech; panic attacks more than once a week; difficulty in understanding complex commands; impairment of short- and long-term memory (e.g., retention of only highly learned material, forgetting to complete tasks); impaired judgment; impaired abstract thinking; disturbances of motivation and mood; difficulty in establishing and maintaining effective work and social relationships. The criteria for a 70 percent rating are: Occupational and social impairment, with deficiencies in most areas, such as work, school, family relations, judgment, thinking, or mood, due to such symptoms as: suicidal ideation; obsessional rituals which interfere with routine activities; speech intermittently illogical, obscure, or irrelevant; near- continuous panic or depression affecting the ability to function independently, appropriately and effectively; impaired impulse control (such as unprovoked irritability with periods of violence); spatial disorientation; neglect of personal appearance and hygiene; difficulty in adapting to stressful circumstances (including work or a worklike setting; inability to establish and maintain effective relationships.) The criteria for a 100 percent rating are: Total occupational and social impairment, due to such symptoms as: gross impairment in thought processes or communication; persistent delusions or hallucinations; grossly inappropriate behavior; persistent danger of hurting self or others; intermittent inability to perform activities of daily living (including maintenance of minimal personal hygiene); disorientation to time or place; memory loss for names of close relatives, own occupation, or own name. 38 C.F.R. § 4.130, Diagnostic Code 9411. After a careful review of the record and for reasons and bases expressed immediately below, the Board finds that the veteran's demonstrated PTSD symptomatology warrants a continuation of the currently assigned 50 percent rating. The criteria for a 50 percent disability rating generally contemplate a moderate severity of psychiatric symptoms, and, for the reasons given below, this is clearly the veteran's situation. The Board notes that the evidence considered in determining the level of impairment under 38 C.F.R. § 4.130 is not restricted to the symptoms provided in the diagnostic code. Instead, the VA must consider all symptoms of a claimant's condition that affect the level of occupational and social impairment, including (if applicable) those identified in the DSM-IV (American Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders (4th ed. 1994)). See Mauerhan, supra. Within the DSM-IV, Global Assessment Functioning (GAF) scores are a scale reflecting the "psychological, social, and occupational functioning on a hypothetical continuum of mental health-illness." See Carpenter v. Brown, 8 Vet. App. 240, 242 (1995); see also Richard v. Brown, 9 Vet. App. 266, 267 (1996). While not determinative, a GAF score is highly probative as it relates directly to the veteran's level of impairment of social and industrial adaptability, as contemplated by the rating criteria for mental disorders. See Massey v. Brown, 7 Vet. App. 204, 207 (1994). According to DSM-IV, a score of 51-60 represents "[m]oderate symptoms (e.g., flat affect and circumstantial speech, occasional panic attacks) OR moderate difficulty in social, occupational, or school functioning, (e.g., few friends, conflicts with peers or co-workers)." Id. At private psychiatric evaluations in February and April 2005, the veteran received a GAF score of 55. At the veteran's December 2005 VA examination, he received a 58. The scores, then, point to moderate symptoms. At his February 2005 evaluation, the veteran was oriented to person, place and time. Recent and remote memory appeared within average limits. The veteran was calm and open in his responses. He had a flat affect and dysphoric mood. The veteran denied any suicidal ideation. The veteran indicated that he had one close friend and described himself as a loner. He reported an aversion to crowds. The veteran reported flashbacks, night sweats and wishes and dreams about staying in Vietnam. He indicated some history of violence and depression. At his April 2005 evaluation, the veteran's symptoms were described more fully. The veteran indicated that loud noises set him on edge and trigger flashbacks to Vietnam. The veteran also reported that seeing Vietnamese people caused him to become highly suspicious and that he has a problem trusting people generally. The veteran reported nightmares once a month. The veteran indicated that he had committed assault and burglary and spent several years in prison. He stated that his legal problems ended in 1983 when he quit using alcohol. During the mental status examination, the veteran was cooperative throughout the interview. Affect was dysthymic and somewhat restricted. Eye contact was intermittent. Speech was of normal rate, volume, and tone, although monotonous. Content was generally logical and goal- directed other than stating that he felt paranoid. He denied any active psychotic process and there was no evidence of such during the interview. He denied any hallucinations, ideas of reference, thought broadcasting, delusions of grandeur or persecutory ideation. He denied any homicidal or suicidal ideation currently. He did report some homicidal ideation towards people who anger him. He also related persistent symptoms of increased arousal including difficulty falling asleep, irritability, difficulty concentrating and an exaggerated startle response. He also appeared to have hypervigilance. The veteran reported some suicidal ideation approximately two years before the examination. The veteran's social functioning showed significant difficulties. The veteran spends time with his brothers and has no friends apart from them. The veteran reported difficulty keeping jobs. His last employment was at a gas station where his girlfriend was his supervisor. At the veteran's December 2005 VA examination, he reported symptoms consistent with the foregoing. The veteran was oriented to person, time and place. His affect was constricted with some dysphoric affect. The veteran had no inappropriate behavior. The veteran had good impulse control without episodes of violence. There were no suicidal or homicidal thoughts present. He had the ability to maintain minimum personal hygiene and had no reported problems with the activities of daily living. His memory was intact. The veteran's avoidant symptoms were the most pervasive, with the veteran only interacting with his brothers and girlfriend of eleven years. The examiner indicated that the effects of PTSD ranging from mild impact on efficiency and productivity to moderate in reliability and relationships with others. Since the December 2005 VA examination, the veteran has not had further treatment or evaluation for his PTSD. The veteran did have a psychiatric examination in connection with the sleep disorder claim discussed above; however, the report specifically states that the veteran's PTSD was not evaluated at that time. The only record pertaining to PTSD is a June 2007 VA clinic visit note. At the time, the veteran had a negative PTSD and depression screening test. With consideration of the entire record, the Board finds that the manifestations of the veteran's service-connected PTSD warrant no more than a 50 percent evaluation. The evidence shows that the veteran has difficulty in adapting to stressful circumstances. Additionally, avoidant behavior has been reported; however, it has not been shown to interfere with routine activities. Suicidal ideation, impaired impulse control, spatial disorientation, neglect of personal appearance and hygiene, and intermittent illogical, obscure, or irrelevant speech has not been shown by the record. Nightmares and depression are intermittent and do not affect the veteran's ability to function independently, appropriately, and effectively. Social withdrawal has been shown by the evidence, as has difficulty in establishing social relationships; however, the veteran has been able to maintain good relationships with his brothers and girlfriend. Some past history of violence and suicidal ideation were reported, but these occurred several years prior to the period on appeal and have not been replicated during the appeal. The Board finds that the veteran's PTSD symptoms are no more than "moderate" and that he does not have any of the symptoms of the criteria for a 70 or 100 percent rating. The Board concludes that the criteria for an initial rating in excess of 50 percent for PTSD have not been met at any time during the period on appeal. See 38 C.F.R. § 4.130, DC 9411. As such, the Board finds that the preponderance of the evidence is against the veteran's PTSD claim. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). d. Left Great Toenail Removal The veteran currently receives a noncompensable rating for loss of the nail of his left great toe as a result of his onychomyocosis and tinea pedis of the left foot. He contends that he is entitled to a compensable rating. For the reasons that follow, the Board concludes that a compensable rating is not warranted. The ratings schedule does not address loss of a toenail. See 38 C.F.R. § 4.71a (2007). The RO assigned the veteran a noncompensable rating under Diagnostic Code (DC) 5299-5284. The use of a hyphenated DC indicates an analogous rating using the criteria of the second part. See 38 C.F.R. § 4.27 (2007). In this case, the RO determined that the veteran's disability did not fit the criteria of the DCs which rate specific foot disabilities and applied the criteria of DC 5284, which rates other injuries of the foot. Diagnostic Code 5284 assigns a 10 percent evaluation for a moderate foot injury; a 20 percent evaluation for a moderately severe foot injury; and a 30 percent evaluation for a severe foot injury. 38 C.F.R. § 4.71a. The Board notes that words such as "severe" and "moderate" are not defined in the Rating Schedule. Rather than applying a mechanical formula, VA must evaluate all evidence, to the end that decisions will be equitable and just. 38 C.F.R. § 4.6 (2007). Although the use of similar terminology by medical professionals should be considered, is not dispositive of an issue. Instead, all evidence must be evaluated in arriving at a decision regarding a request for an increased disability rating. 38 U.S.C.A. § 7104 (West 2002); 38 C.F.R. §§ 4.2, 4.6 (2007). The Board notes that DC 5284 does not contain a noncompensable rating. See 38 C.F.R. § 4.71a. In the event that a DC does not contain a noncompensable rating, one may still be assigned if the disability does not reach the minimum compensable level. See 38 C.F.R. § 4.31 (2007). In sum, the RO applied DC 5284 and concluded that the veteran's toenail loss disability was not manifested by at least "moderate" symptoms. At a November 2004 VA examination, the veteran's left great toe was without the nail. The left great toe was only minimally tender. There were no skin breakdowns and no drainage. The removal site was well healed in both cuticle and paronychial areas. He had full range of motion of the great toe. The veteran reported trouble running and jumping, but also indicated that he had those problems prior to the toenail removal. At his March 2007 examination, the left great toenail was removed with no signs of infection or complication. The veteran had a slight remnant of the left great toenail, that may be the nail starting to grow back. The veteran had no pain in his feet and had good coarse sensation. The Board finds that the veteran's loss of the toenail of the left great toe resulting in a disability which is no more than "mild." The veteran has minimal, if any, functional impairment as a result of the loss of the left great toenail, which may, in fact, be returning. The veteran's disability has not been more than "mild" at any point during the period on appeal. As such, the Board concludes that a compensable rating is not warranted under DC 5284 at any time. See 38 C.F.R. § 4.71a, supra; Fenderson, supra. The Board has considered weather the veteran's disability would warrant a higher evaluation under other Diagnostic Codes pertaining to the foot. However, the veteran does not have acquired flat foot, bilateral weak foot, claw foot, anterior metatarsalgia, hallus valgus, hallux rigidus, hammer toe, or malunion or nonunion of the tarsal or metatarsal bones to warrant an evaluation under Diagnostic Codes 5276- 5283. See 38 C.F.R. § 4.71a, Diagnostic Codes 5276-5283 (2007). As such, the Board finds that the preponderance of the evidence is against the veteran's claim. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). e. Onychomyocosis and Tinea Pedis The veteran contends that he is entitled to a rating in excess of 10 percent for his onychomyocosis and tinea pedis of the bilateral feet. His representative argues in particular that separate 10 percent ratings should be assigned for each foot. For the reasons that follow, the Board concludes that a rating in excess of 10 percent, including separate 10 percent ratings for each foot, is not warranted. The veteran's disability is rated under Diagnostic Code 7813, addressing dermatophytosis. Dermatophytosis, including tinea pedis, is to be rated as disfigurement of the head, face, or neck (DC 7800), scars (DC's 7801, 7802, 7803, 7804, or 7805), or dermatitis (DC 7806), depending upon the predominant disability. 38 C.F.R. § 4.118, DC 7813 (2007). Under DC 7813, skin disability is rated depending upon the predominant disability, and where, as here, it is onychomycosis, it will be rated as dermatitis or eczema under DC 7806. 38 C.F.R. § 4.118 (2007). DC 7806 provides that for dermatitis a 10 percent rating is assigned for at least 5 percent, but less than 20 percent, of the entire body, or at least 5 percent, but less than 20 percent, of exposed areas affected or intermittent systemic therapy such as corticosteroids or other immunosuppressive drugs required for a total duration of less than six weeks during the past 12-month period. A 30 percent evaluation will be assigned where 20 to 40 percent of the entire body or 20 to 40 percent of exposed area is affected, or; systemic therapy such as corticosteroids or other immunosuppressive drugs required for a total duration of six weeks or more, but not constantly, during the past 12-month period. A 60 percent evaluation will be assigned for dermatitis that covers more than 40 percent of the entire body or more than 40 percent of exposed areas affected, or with constant or near constant systemic therapy such as corticosteroids or other immunosuppressive drugs required during the past 12- month period. 38 C.F.R. § 4.118 (2007). In reviewing this DC, the Board finds the veteran's representative's argument to be without merit. A separate rating for each foot is not warranted because the DC is premised on a compilation of the affected areas, not a division of them. See id. At a minimum, to be entitled to an increased rating, the evidence must show that 20 to 40 percent of the entire body or 20 to 40 percent of exposed area is affected, or; systemic therapy such as corticosteroids or other immunosuppressive drugs required for a total duration of six weeks or more, but not constantly, during the past 12-month period. See id. At a November 2004 VA examination, the veteran's onychomyocosis and tinea pedis were evaluated. He had bilateral mild erythematous lesions without active vesicles or pustules. The tip of the right great toe had been amputated. The left great toe was without the nail. The remaining left toes did not demonstrate evidence of fungal infections or onychomyocosis. The left great toe was only minimally tender. There were no skin breakdowns and no drainage. The removal site was well healed in both cuticle and paronychial areas. He had full range of motion of the great toe. The veteran reported trouble running and jumping, but also indicated that he had those problems prior to the toenail removal. At his March 2007 examination, the veteran's feet were smooth to the touch, without roughness, flakes or signs of current tinea pedis. The veteran had yellowed, thickened toenails bilaterally. The left great toenail was removed with no signs of infection or complication. The veteran had a slight remnant of the left great toenail, that may be the nail starting to grow back. The veteran had no pain in his feet and had good coarse sensation. The veteran's remaining, and substantial, VA treatment records do not show additional treatment for his feet. The Board finds that the evidence shows that the veteran has not met the criteria for an increased rating at any time during the period on appeal. The veteran's tinea pedis and onychomyocosis are confined to an area which is not exposed. While a calculation of affected area of the entire body was not performed, the Board notes that the veteran's disability is confined to the feet which could not be equivalent to 20 percent of the veteran's entire body. The Board has reviewed the veteran's treatment records and found no references to corticosteroid or immunosuppressive drug treatment at any time. As such, the Board finds that the criteria for a rating in excess of 10 percent for onychomyocosis and tinea pedis are not met. See 38 C.F.R. § 4.118, DC 7806, 7813. As such, the Board finds that the preponderance of the evidence is against the veteran's claim. Consequently, the benefit-of-the-doubt rule does not apply, and the claim must be denied. 38 U.S.C.A. § 5107(b) (West 2002); Gilbert v. Derwinski, 1 Vet. App. 49, 55 (1990). ORDER Entitlement to service connection for tinnitus is denied. Entitlement to service connection for residuals of a right eye injury is denied. Entitlement to service connection for a sleep disorder claimed as secondary to service-connected back disability is denied. Entitlement to an initial rating in excess of 20 percent for degenerative disc disease of the lumbar spine with stenosis is denied. Entitlement to an initial rating in excess of 10 percent for radiculopathy of the right leg is denied. Entitlement to an initial a rating in excess of 10 percent for radiculopathy of the left leg is denied. Entitlement to an initial rating in excess of 50 percent for PTSD is denied. Entitlement to an initial compensable rating for loss of the left great toenail is denied. Entitlement to a rating in excess of 10 percent for onychomyocosis and tinea pedis of the feet is denied. REMAND The veteran's claim for an increased rating for COPD must be remanded. The veteran initially brought a claim for an increase in 2006. The RO reduced the veteran's disability rating from 30 to 10 percent in an April 2007 rating decision, effective September 1, 2006. The RO concluded, apparently, that because the reduction did not change the veteran's combined disability rating of 80 percent, this action was permissible. The veteran's representative immediately contested this action in the Notice of Disagreement. The RO disregarded his contentions and proceeded to evaluate the merits of this case solely on the basis of a claim for increased rating in excess of 10 percent. Reductions are governed by 38 C.F.R. § 3.105(e), which describes procedural hurdles which must be met prior to a rating reduction. The U.S. Court of Appeals for Veterans Claims (Court) has consistently held that, when a veteran's disability rating is reduced by a RO without following the applicable regulations, the reduction is void ab initio. See Greyzck v. West, 12 Vet. App. 288, 292 (1999). The Court's caselaw provides that where a rating reduction was made without observance of law, although a remand for compliance with that law would normally be an adequate remedy, in a rating reduction case, the erroneous reduction must be vacated and the prior rating restored. Schafrath v. Derwinski, 1 Vet. App. 589, 595 (1991). The application of this body of caselaw has been called into question by the recent case of Stelzel v. Mansfield, 508 F.3d 1345 (Fed. Cir. 2007). The case of Stelzel concerned a case where a reduction in the specific rating of a disability did not reduce the combined rating and compensation received by a veteran. Id. The opinion decided that no clear and unmistakable error has been committed in such a reduction, finding that this act neither the predecessor statute to 38 U.S.C.A. § 5112(b)(6) nor its implementing regulation, the predecessor to 38 C.F.R. § 3.105(e) require adherence to the established procedures if the veteran's compensation was not changed. Id. In light of Stelzel, the Board concludes that an automatic resumption of the 30 percent rating for COPD is not warranted in this case. The Board notes, however, that Stelzel applies to claims of CUE, not to cases without final decisions. Active cases for increased ratings and reductions must also satisfy the requirements of the Veterans Claims Assistance Act (VCAA). In this case, the duty to notify requirements for an increased-compensation claim, section 5103(a) compliant notice must meet the four part test established in Vazquez- Flores, discussed, above. Here, the VCAA notice provided for the veteran's increased rating claim did not satisfy the second requirement set out above as they relate to increases or any of the elements as they pertain to reductions. The Board, therefore, remands for VCAA compliant notice as to the veteran's underlying increased rating claim. Because the RO also reduced the veteran's rating, the Board must remand so that notice of the procedures and especially the evidentiary burden in reduction can be provided to the veteran. In cases where a rating has been in effect for 5 years or more, though material improvement in the physical or mental condition is clearly reflected, the rating agency must make reasonably certain that the improvement will be maintained under the conditions of ordinary life. Kitchens v. Brown, 7 Vet. App. 320, 324 (1995). The 5-year period is calculated from the effective date of the rating to the effective date of the reduction. Brown v. Brown, 5 Vet. App. 413, 419 (1995). The Board notes that the veteran's COPD rating had been in effect for more than five years. Under 38 C.F.R. § 3.344, the RO must find the following: (1) based on a review of the entire record, the examination forming the basis for the reduction is full and complete, and at least as full and complete as the examination upon which the rating was originally based; (2) the record clearly reflects a finding of material improvement; and (3) it is reasonably certain that the material improvement found will be maintained under the ordinary conditions of life. Thus, for disabilities that have continued for five years or more, the issue is whether material improvement in a veteran's disability was demonstrated in order to warrant a reduction in such compensation benefits. See Kitchens v. Brown, 7 Vet. App. 320 (1995); Brown v. Brown, 5 Vet. App. 413 (1993). In such cases, examinations less full and complete than those on which payments were authorized will not be used as the basis for reductions. 38 C.F.R. § 3.344(a). The Board remands to provide notice of the reductions requirements of 38 C.F.R. §§ 3.105(e) and 3.344(a). Since resolution of the TDIU claim is dependent, at least in part, on the outcome of the claim for an increased rating for COPD, the Board will defer consideration of that claim at this time. Accordingly, the case is REMANDED for the following action: 1. Provide to the veteran all notification action required by the Veterans Claims Assistance Act of 2000, Pub. L. No. 106-475, 114 Stat. 2096 (2000), with respect to the increased rating for COPD claim to include the propriety of the April 2007 reduction in rating. The notice should conform to the requirements of Vazquez-Flores, including notice of 38 C.F.R. §§ 3.105(e) and 3.344(a), as described above. Any notice given, or action taken thereafter, must comply with current, controlling legal guidance. 2. Then, the RO should readjudicate the claim on the merits. If the benefits sought are not granted, the veteran and his representative should be furnished a SSOC and afforded a reasonable opportunity to respond before the record is returned to the Board for further review. The veteran has the right to submit additional evidence and argument on the matter or matters the Board has remanded. Kutscherousky v. West, 12 Vet. App. 369 (1999). This claim 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. 2007). ______________________________________________ K. PARAKKAL Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
