Entitlement to an initial evaluation in excess of 50 percent for posttraumatic stress disorder (PTSD). 2. Entitlement to an initial compensable evaluation for bilateral hearing loss. 3. Entitlement to service connection for a bilateral knee disorder. 4. Entitlement to service connection for eczema (claimed as a skin condition), to include as due to herbicide exposure. REPRESENTATION Appellant represented by: The American Legion ATTORNEY FOR THE BOARD K. Osegueda, Associate Counsel INTRODUCTION The Veteran had active service from January 1963 to January 1967. He served in the Republic of Vietnam from April 1965 to December 1965. This matter comes before the Board of Veterans' Appeals (Board) on appeal from rating decisions of the Department of Veterans Affairs (VA) Regional Office (RO) in Cleveland, Ohio. In an April 2005 rating decision, the RO denied entitlement to service connection for the residuals of a bilateral knee injury and eczema. In another April 2005 rating decision, the RO granted service connection for PTSD and assigned a30 percent evaluation effective from January 26, 2004. The RO later increased that evaluation to 50 percent as of January 26, 2004. Applicable law mandates that, when a veteran seeks an increased evaluation, it will generally be presumed that the maximum benefit allowed by law and regulation is sought, and it follows that such a claim remains in controversy where less than the maximum benefit available is awarded. See AB v. Brown, 6 Vet. App. 35 (1993). In a February 2007 rating decision, the RO granted service connection for bilateral hearing loss and assigned a noncompensable evaluation effective from January 26, 2004. The Board notes that the Veteran requested a hearing in August 2009 and May 2010. In May 2013, he was notified that he was scheduled to appear at a hearing at the RO in June 2013. However, in response to the notification, he indicated that he was unable to attend the scheduled hearing and he wanted to withdraw his hearing request. Therefore, the hearing request is considered withdrawn, and no further action is necessary. See 38 C.F.R. § 20.704 (2012). In addition to the paper claims file, there are Virtual VA and Veterans Benefits Management System (VBMS) paperless files associated with the Veteran's case. A review of the documents in the Virtual VA paperless claims file reveals VA treatment records that are relevant to the issues on appeal. The RO considered those additional treatment records and readjudicated the claims in a February 2013 supplemental statement of the case (SSOC). Additionally, the issues of entitlement to evaluations in excess of 20 percent for degenerative joint disease of the lumbar spine and in excess of 10 percent for tinnitus; entitlement to service connection for melanoma, to include as secondary to herbicide exposure; and entitlement to a total evaluation based upon individual unemployability due to service-connected disabilities (TDIU) have been raised by the record, but have not been adjudicated by the Agency of Original Jurisdiction (AOJ). Therefore, the Board does not have jurisdiction over these issues, and they are referred to the AOJ for appropriate action. The issues of entitlement to service connection for eczema and to a higher initial evaluation for PTSD 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. During the pendency of the appeal, the Veteran manifested, at worst, Level I hearing in his right ear and Level V hearing in his left ear. 2. A bilateral knee disorder did not manifest during service or within one year thereafter and is not causally or etiologically related to service. CONCLUSIONS OF LAW 1. The criteria for an initial compensable evaluation for bilateral hearing loss have not been met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. § 3.102, 3.159, 4.1-4.14, 4.85, 4.86, Diagnostic Code 6100 (2012). 2. The criteria for entitlement to service connection for a bilateral knee disorder have not been met. 38 U.S.C.A. §§ 1110, 1112, 1131, 1137, 5103, 5103A, 5107 (West 2002); 38 C.F.R. §§ 3.102, 3.159, 3.303, 3.304, 3.307, 3.309 (2012). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS Upon receipt of a substantially complete application for benefits, VA must notify the claimant of what information or evidence is needed in order to substantiate the claim and it must assist the claimant by making reasonable efforts to get the evidence needed. 38 U.S.C.A. §§ 5103(a), 5103A; 38 C.F.R. § 3.159(b); see Quartuccio v. Principi, 16 Vet. App. 183, 187 (2002). The notice required must be provided to the claimant before the initial unfavorable decision on a claim for VA benefits, and it must (1) inform the claimant about the information and evidence not of record that is necessary to substantiate the claim; (2) inform the claimant about the information and evidence that VA will seek to provide; and, (3) inform the claimant about the information and evidence the claimant is expected to provide. 38 U.S.C.A. §§ 5103(a); 38 C.F.R. § 3.159(b)(1); Pelegrini v. Principi, 18 Vet. App. 112, 120 (2004). In Dingess v. Nicholson, 19 Vet. App. 473 (2006), the United States Court of Appeals for Veterans Claims (Court) held that, upon receipt of an application for a service connection claim, 38 U.S.C. § 5103(a) and 38 C.F.R. § 3.159(b) require VA to review the information and the evidence presented with the claim and to provide the claimant with notice of what information and evidence not previously provided, if any, will assist in substantiating, or is necessary to substantiate, each of the five elements of the claim, including notice of what is required to establish service connection and that a disability rating and an effective date for the award of benefits will be assigned if service connection is awarded. With regard to claims for increased disability ratings for service-connected conditions, the law requires VA to notify the claimant that, to substantiate a claim, the claimant must provide, or ask VA to obtain, medical or lay evidence demonstrating a worsening or increase in severity of the disability. 38 U.S.C.A. §5103(a); 38 C.F.R. § 3.159(b); Vazquez-Flores v. Peake, 22 Vet. App. 37 (2008), vacated and remanded sub nom. Vazquez-Flores v. Shinseki, 580 F.3d 1270 (Fed. Cir. 2009). 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. Finally, the notice must provide examples of the types of medical and lay evidence that the Veteran may submit (or ask the VA to obtain) that are relevant to establishing her or his entitlement to increased compensation. However, the notice required by section 5103(a) need not be specific to the particular Veteran's circumstances; that is, VA need not notify a Veteran of alternative diagnostic codes that may be considered or notify of any need for evidence demonstrating the effect that the worsening of the disability has on the particular Veteran's daily life. Vazquez-Flores v. Shinseki, 580 F.3d 1270 (Fed. Cir. 2009). The notice must be provided prior to an initial unfavorable decision by the agency of original jurisdiction (AOJ). Mayfield v. Nicholson, 444 F.3d 1328 (Fed. Cir. 2006); Pelegrini v. Principi, 18 Vet. App. 112 (2004). In this case, the Veteran is challenging, in part, the initial evaluation assigned following the grant of service connection for bilateral hearing loss. In Dingess, the Court held that, in cases where service connection has been granted and an initial disability rating and effective date have been assigned, the typical service-connection claim has been more than substantiated, it has been proven, thereby rendering section 5103(a) notice no longer required because the purpose that the notice is intended to serve has been fulfilled. Id. at 490-91. See also VAOPGCPREC 8- 2003 (December 22, 2003). Thus, VA's duty to notify has been satisfied with respect to the issue of entitlement to a higher initial evaluation for bilateral hearing loss. With respect to the claim for service connection for a bilateral knee disorder, the RO provided the Veteran with a notification letter in August 2004, prior to the initial decision on the claim in April 2005. Therefore, the timing requirement of the notice as set forth in Pelegrini has been met and to decide the appeal would not be prejudicial to the claimant. Moreover, the requirements with respect to the content of the notice were met in this case. The August 2004 letter informed the Veteran of the information and evidence needed to substantiate his claim for service connection and notified him of the division of responsibilities in obtaining such evidence. The Veteran was provided an explanation concerning how a disability rating is determined for a service-connected disorder and the basis for determining an effective date upon the grant of any benefit sought, in compliance with Dingess, 19 Vet. App. at 490-491, in a February 2007 statement of the case (SOC). The Board notes that the February 2007 notice was not provided prior to the April 2005 rating decision. Such an error can be effectively "cured" by providing any necessary notice and then readjudicating the claim in a SOC or supplemental statement of the case (SSOC). Mayfield v. Nicholson, 499 F.3d 1317 (Fed. Cir. 2007)(Mayfield IV); Prickett v. Nicholson, 20 Vet. App. 370 (2006). In this case, the RO provided the notice in the February 2007 SOC and readjudicated the claim in various SSOCs dated in July 2009, February 2010, April 2010, March 2012, and February 2013. Moreover, any questions regarding disability ratings and effective dates are rendered moot because the claim is denied in the decision below. Accordingly, the Board concludes that there is no prejudicial error in the timing of the February 2007 notice. See Shinseki v. Sanders, 129 S. Ct. 1696 (2009) (reversing prior case law imposing a presumption of prejudice on any notice deficiency). In addition, the duty to assist the Veteran has also been satisfied in this case. The Veteran's service treatment records, as well as all identified and available post- service medical records, including Social Security Administration (SSA) records, are in the claims file and were reviewed by both the RO and the Board in connection with the claim. The Veteran has not identified any other outstanding records that are pertinent to the issue being decided herein. 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. McLendon v. Nicholson, 20 Vet. App. 79 (2006). In this case, the Veteran was afforded VA audiology examinations in October 2006, March 2010, and December 2011; a VA joints examination in September 2006; and a VA general medical examination in November 2012. Additionally, the September 2006 VA examiner provided an addendum opinion in December 2006. The Board finds that the medical opinions obtained in this case are adequate, as they are predicated on a full reading of the available service treatment records contained in the Veteran's claims file. They consider all of the pertinent evidence of record and provide a complete rationale for the opinions stated. Accordingly, the Board finds that VA's duty to assist with respect to obtaining a VA examination or opinion with respect to the issues on appeal has been met. 38 C.F.R. § 3.159(c)(4). Moreover, during the course of the appeal, the Compensation and Pension (C&P) hearing examination worksheets were revised to include a discussion of the effect of the Veteran's hearing loss disability on occupational functioning and daily activities. See Revised Disability Examination Worksheets, Fast Letter 07-10 (Dep't of Veterans Affairs Veterans, Apr. 24, 2007); see also 38 C.F.R. § 4.10 (2012). In Martinak v. Nicholson, 21 Vet. App. 447 (2007) the Court held that in addition to dictating objective test results, a VA audiologist must fully describe the functional effects caused by a hearing disability in his or her final report. Martinak, 21 Vet. App. at 455. In this case, the December 2011 VA examiner specifically addressed the effect of the Veteran's hearing loss on his occupational functioning and daily activities. In this regard, he noted that the Veteran's hearing loss had no significant occupational impact despite the Veteran's complaints that he had difficulty in all listening situations. He also noted the Veteran's reports that he had significant difficulty hearing conversations in background noise, over the phone, or when he was unable to see the speaker's face. Moreover, in Martinak, the Court noted that, even if an audiologist's description of the functional effects of the appellant's hearing disability was somehow defective, the appellant bears the burden of demonstrating any prejudice caused by a deficiency in the examination. There have been no allegations of any prejudice caused by a deficiency in the examination here. There is also no objective evidence indicating that there has been a material change in the severity of the Veteran's service-connected bilateral hearing loss disability since he was last examined. 38 C.F.R. § 3.327(a) (2012). 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. VA has further assisted the Veteran and his representative throughout the course of this appeal by providing them with SOCs and various SSOCs, which informed them of the laws and regulations relevant to the Veteran's claims. The Veteran has not made the RO or the Board aware of any additional evidence that needs to be obtained in order to fairly decide the particular claims on appeal. He has been given ample opportunity to present evidence and argument in support of his claims. For these reasons, the Board concludes that VA has fulfilled the duty to assist the Veteran in this case. Hence, there is no error or issue that precludes the Board from addressing the merits of this appeal. Increased Rating Disability ratings are determined by applying the criteria set forth in the VA Schedule for Rating Disabilities, found in 38 C.F.R., Part 4. The rating schedule is primarily a guide in the evaluation of disability resulting from all types of diseases and injuries encountered as a result of or incident to military service. The ratings are intended to compensate, as far as can practicably be determined, the average impairment of earning capacity resulting from such diseases and injuries and their residual conditions in civilian occupations. 38 U.S.C.A. § 1155; 38 C.F.R. § 4.1. 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 that rating. 38 C.F.R. § 4.7. In considering the severity of a disability, it is essential to trace the medical history of the veteran. 38 C.F.R. §§ 4.1, 4.2, 4.41. Consideration of the whole-recorded history is necessary so that a rating may accurately reflect the elements of disability present. 38 C.F.R. § 4.2; Peyton v. Derwinski, 1 Vet. App. 282 (1991). While the regulations require review of the recorded history of a disability by the adjudicator to ensure a more accurate evaluation, the regulations do not give past medical reports precedence over the current medical findings. Where an increase in the disability rating is at issue, as in this case, the present level of the veteran's disability is the primary concern. Francisco v. Brown, 7 Vet. App. 55, 58 (1994). Similarly, where a veteran appeals the initial rating assigned for a disability when a claim for service connection for that disability has been granted, evidence contemporaneous with the claim for service connection and with the rating decision granting service connection would be most probative of the degree of disability existing at the time that the initial rating was assigned and should be the evidence "used to decide whether an [initial] rating on appeal was erroneous . . . ." Fenderson v. West, 12 Vet. App. 119, 126 (1999). If later evidence obtained during the appeal period indicates that the degree of disability increased or decreased following the assignment of the initial rating, "staged" ratings may be assigned for separate periods of time based on facts found. Id.; see also Hart v. Mansfield, 21 Vet. App. 505 (2007) (VA's determination of the "present level" of a disability may result in a conclusion that the disability has undergone varying and distinct levels of severity throughout the entire time period the increased rating claim has been pending). The Veteran's bilateral hearing loss is currently assigned a noncompensable evaluation pursuant to 38 C.F.R. § 4.85, Diagnostic Code 6100. In evaluating service-connected hearing loss, disability ratings are derived by a mechanical application of the rating schedule to the numeric designations assigned after audiometric evaluations are performed. Lindenmann v. Principi, 3 Vet. App. 345, 349 (1992). Evaluations of bilateral hearing loss range from noncompensable to 100 percent based on an organic impairment of hearing acuity, as measured by controlled speech discrimination tests in conjunction with the average hearing threshold, as measured by puretone audiometric tests in the frequencies of 1000, 2000, 3000 and 4000 cycles per second. The rating schedule establishes 11 auditory acuity Levels designated from Level I for essentially normal hearing acuity through Level XI for profound deafness. VA audiological evaluations are conducted using a controlled speech discrimination test together with the results of puretone audiometry tests. The vertical line in Table VI (printed in 38 C.F.R. § 4.85) represents nine categories of the percentage of discrimination based on a controlled speech discrimination test. The horizontal columns in Table VI represent 9 categories of decibel loss based on the puretone audiometry test. The numeric designation of impaired hearing (Levels I through XI) is determined for each ear by intersecting the vertical row appropriate for the percentage of discrimination and the horizontal column appropriate to the puretone decibel loss. The percentage evaluation is found from Table VII in 38 C.F.R. § 4.85 by intersecting the vertical column appropriate for the numeric designation for the ear having the better hearing acuity and the horizontal row appropriate for the numeric designation for the level for the ear having the poorer hearing acuity. For example, if the better ear had a numeric designation of Level "V" and the poorer ear had a numeric designation of Level "VII" the percentage evaluation is 30 percent. See 38 C. F. R. § 4.85. However, whereas here, the veteran is service-connected in only one ear, in order to determine the percentage evaluation from Table VII, the nonservice- connected ear is assigned a numeric designation of Level "I" for evaluation purposes. See 38 C.F.R. § 4.85(f). Regulations also provide that in cases of exceptional hearing loss, i.e., when the puretone threshold at each of the four specified frequencies (1,000, 2,000, 3,000 and 4,000 hertz) is 55 decibels or more, the rating specialist will determine the Roman numeral designation for hearing impairment from either Table VI or Table VIa, whichever results in the higher numeral. Each ear will be evaluated separately. 38 C.F.R. § 4.86(a). The provisions of 38 C.F.R. § 4.86(b) further provide that when the puretone threshold is 30 decibels or less at 1,000 hertz and 70 decibels or more at 2,000, the rating specialist will determine the Roman numeral designation for hearing impairment from either Table VI or VIa, whichever results in the higher numeral. That numeral will then be evaluated to the next higher Roman numeral.

The Veteran was afforded a VA examination in October 2006 in connection with his claim. He reported difficulty understanding speech due to his hearing loss. An audiogram revealed pure tone thresholds, in decibels, as follows: HERTZ A 500 B 1000 C 2000 D 3000 E 4000 (B+C+D+E )/4 Average RIGHT 15 20 25 50 50 36 LEFT 20 35 55 65 65 55 Speech recognition scores were 92 percent in the right ear and 82 percent in the left ear. The examiner noted that the audiogram results from 500 Hertz to 4000 Hertz indicated normal hearing acuity through 2000 Hertz, sloping to a moderate sensorineural hearing loss in the right ear, and normal hearing acuity at 500 Hertz, sloping to moderately severe sensorineural hearing loss in the left ear. During a July 2006 VA audiology consultation, the Veteran reported that he had bilateral hearing loss, but his left ear was worse than the right ear. He indicated that he had the most difficulty understanding his wife when she spoke to him. An otoscopic examination was unremarkable. Audiogram results were not provided; however, the audiologist noted that pure tone audiometry testing indicated normal hearing through 1000 Hertz, sloping to a severe sensorineural hearing loss in the right ear, and normal hearing through 500 Hertz, sloping to a profound sensorineural hearing loss in the left ear. Speech recognition scores were 100 percent for the right ear and 72 percent for the left ear. An August 2006 VA audiology diagnostic study note indicated that an auditory brainstem response (ABR) test was recommended due to the Veteran's asymmetric sensorineural hearing loss. The study revealed results indicating normal neural transmission through auditory brainstem pathways. It was not consistent with retrocochlear pathology. The audiologist placed an order for hearing aids. During a December 2006 private psychiatric evaluation, the Veteran reported that he wore a hearing aid and continued to have difficulty hearing when there were a lot of noises around him. In his SSA disability application filed in January 2007, the Veteran reported that his hearing loss made being in noisy environments difficult and dangerous. He indicated that his last employer terminated his employment due to concerns about his physical and mental capabilities. Specifically, the employer noted the Veteran's back problems, a permanent weight restriction of 10 pounds, and memory difficulty. In a November 2007 statement, the Veteran reported that he was unable to hear customers' orders and needed orders repeated several times when he worked the counter at fast food restaurants for six weeks. He indicated that, in July 2005, he tore his rotator cuff in his left shoulder and was unable to perform his job as an acoustic ceiling installer. Following surgery and rehabilitation, he was unable to return to his old job. He reported that he was provided a psychological evaluation as part of his vocational rehabilitation program, and as a result of the evaluation, it was recommended that he file for SSA disability benefits because his psychiatric symptoms and hearing loss prohibited him from returning to any type of employment. He stated that the problems presented by his psychiatric disorder and hearing loss were a "major factor" in his inability to find and maintain employment. In a September 2009 VA audiology consultation note, the examining audiologist noted that the Veteran was previously diagnosed with bilateral sensorineural hearing loss. He indicated that the results of an audiogram showed normal hearing from 250 to 500 Hertz, sloping to a mild to moderately severe sensorineural hearing loss from 1000 to 8000 Hertz in the right ear, and normal hearing from 250 to 5000 Hertz, sloping to a mild to severe sensorineural hearing loss from 1000 to 8000 Hertz in the left ear. During a March 2010 VA examination, the Veteran reported difficulty hearing conversations. An audiogram revealed pure tone thresholds, in decibels, as follows: HERTZ A 500 B 1000 C 2000 D 3000 E 4000 (B+C+D+E )/4 Average RIGHT 20 35 40 55 65 48.75 LEFT 30 35 55 60 75 56.25 Speech recognition scores were 94 percent in the right ear and 72 percent in the left ear. The examiner noted that the audiogram results showed essentially normal hearing acuity at 250 and 500 Hertz, sloping to a severe sensorineural hearing loss in both ears. He opined that the Veteran's hearing loss had significant effects on his occupational functioning. He indicated that the Veteran's hearing loss caused poor social interactions and hearing difficulty. A December 2011 VA examination audiogram revealed pure tone thresholds, in decibels, as follows: HERTZ A 500 B 1000 C 2000 D 3000 E 4000 (B+C+D+E )/4 Average RIGHT 20 35 45 60 70 52 LEFT 30 40 60 65 80 61 Speech recognition scores were 96 percent for the right ear and 72 percent for the left ear. The diagnosis was bilateral sensorineural hearing loss. The examiner opined that the Veteran's hearing loss impacted the ordinary conditions of daily life, including his ability to work. The Veteran reported difficulty hearing in "all listening situations," especially in background noise, and he often had to ask people to repeat themselves. The examiner noted that he did not consider the Veteran unemployable due to his hearing loss. He noted that many occupations do not rely significantly upon hearing and may be performed despite a hearing loss. He indicated that the Veteran may have difficulty hearing conversations in background noise, on the phone, and when he was unable to see the speaker's face. The foregoing evidence shows that the Veteran is not entitled to an increased evaluation for bilateral hearing loss. The October 2006 VA audiometric findings equate to Level I hearing in the right ear and Level IV hearing in the left ear. See 38 C.F.R. § 4.85, Table VI. When those values are applied to Table VII, it is apparent that the currently assigned noncompensable evaluation for the Veteran's bilateral hearing loss is accurate and appropriately reflects his bilateral hearing loss under the provisions of 38 C.F.R. § 4.85. Likewise, the March 2010 VA audiometric findings equate to Level I hearing in the right ear and Level V hearing in the left ear. See 38 C.F.R. § 4.85, Table VI. When those values are applied to Table VII, it is again apparent that the currently assigned noncompensable evaluation for the Veteran's bilateral hearing loss is accurate and appropriately reflects his bilateral hearing loss under the provisions of 38 C.F.R. § 4.85. Additionally, the December 2011 VA audiometric findings equate to Level I hearing in the right ear and Level V hearing in the left ear. See 38 C.F.R. § 4.85, Table VI. When those values are applied to Table VII, a compensable evaluation is still not warranted. The Board has also considered whether an initial compensable evaluation for bilateral hearing loss is warranted under 38 C.F.R. § 4.86. However, the Veteran's disability does not meet the requirements of 38 C.F.R. § 4.86. In this regard, the available audiometric findings do not show the Veteran to have puretone thresholds of 55 decibels or more at each of the frequencies of 1,000, 2,000, 3,000 and 4,000 hertz or a puretone threshold of 30 decibels or less at 1,000 hertz and 70 decibels or more at 2,000 hertz. Thus, the Board finds that the noncompensable evaluation is appropriate and that there is no basis for awarding a higher initial evaluation. In reaching this decision, the potential application of various provisions of Title 38 Code of Federal Regulations have been considered, whether or not they were raised by the Veteran. Schafrath v. Derwinski, 1 Vet. App. 589 (1991). In particular, the Board has considered the provisions of 38 C.F.R. § 3.321(b)(1). However, in this case, the Board finds that the record does not show that the Veteran's bilateral hearing loss is so exceptional or unusual as to warrant the assignment of a higher rating on an extra- schedular basis. See 38 C.F.R. § 3.321(b)(1) (2012). The threshold factor for extraschedular consideration is a finding that the evidence before VA presents such an exceptional disability picture that the available schedular evaluations for that service-connected disability are inadequate. See Thun v. Peake, 22 Vet. App. 111 (2008). In this regard, there must be a comparison between the level of severity and symptomatology of the claimant's service- connected disability with the established criteria found in the rating schedule for that disability. If the criteria reasonably describe the claimant's disability level and symptomatology, then the claimant's disability picture is contemplated by the rating schedule and the assigned schedular evaluation is therefore adequate, and no extraschedular referral is required. Id., see also VAOGCPREC 6-96 (Aug. 16, 1996). Otherwise, if the schedular evaluation does not contemplate the claimant's level of disability and symptomatology and is found inadequate, VA must determine whether the claimant's exceptional disability picture exhibits other related factors, such as those provided by the extraschedular regulation (38 C.F.R. § 3.321(b)(1)) as "governing norms" (which include marked interference with employment and frequent periods of hospitalization). The evidence in this case does not show such an exceptional disability picture that the available schedular evaluation for the service-connected disability is inadequate. A comparison between the level of severity and symptomatology of the Veteran's assigned rating with the established criteria found in the rating schedule shows that the rating criteria reasonably describe the Veteran's disability level and symptomatology. As discussed above, there are higher ratings available under the diagnostic code, but the Veteran's disability is not productive of such manifestations. As such, it cannot be said that the available schedular evaluation for the disability is inadequate. The Board further observes that, even if the available schedular evaluation for the disability is inadequate (which it manifestly is not), the Veteran does not exhibit other related factors such as those provided by the regulation as "governing norms." The record does not show that the Veteran has required frequent hospitalizations for his bilateral hearing loss, and there is nothing in the record to indicate that the Veteran's hearing loss causes impairment with employment over and above that which is contemplated in the assigned schedular rating. See Van Hoose v. Brown, 4 Vet. App. 361, 363 (1993) (noting that the disability rating itself is recognition that industrial capabilities are impaired). Indeed, as noted above, the Veteran reported that his hearing loss made it difficult to hear customers' orders while working at the counter of a fast food restaurant and, in combination with his psychiatric symptoms, his hearing loss prevented him from finding and maintaining employment; however, the evidence of record suggests that the Veteran's usual employment was installing acoustic ceilings and he was unable to work due to physical limitations from orthopedic disabilities. In fact, in his January 2007 SSA disability benefits application, the Veteran indicated that his last employer terminated his employment due to concerns about his physical and mental capabilities. Specifically, the employer noted the Veteran's back problems, a permanent weight restriction of 10 pounds, and memory difficulty. He did not mention that his employer had concerns regarding his hearing loss. Moreover, the December 2011 VA examiner noted that he did not consider the Veteran unemployable due to his hearing loss. He acknowledged that the Veteran may have difficulty hearing conversations in background noise, on the phone, or when he was unable to see the speaker's face, but he noted that many occupations do not rely significantly upon hearing and may be performed despite hearing loss. Based on the foregoing, the Board finds that the requirements for an extraschedular evaluation for the Veteran's service-connected bilateral hearing loss under the provisions of 38 C.F.R. § 3.321(b)(1) have not been met. Bagwell v. Brown, 9 Vet. App. 337 (1996); Shipwash v. Brown, 8 Vet. App. 218 (1995); Thun v. Peake, 22 Vet. App. 111 (2008). Service Connection The Veteran contends that he has a current bilateral knee disorder resulting from an injury in service. Specifically, he reported that he was thrown off of a tank during his service in Vietnam. Additionally, he reported that he had other injuries to his knees from the "physical wear and tear from jumping from helicopters, humping 80 pound field transport packs..., and being constantly wet for 9 months while in Vietnam..." See March 2004 statement. Service connection may be established for disability resulting from personal injury suffered or disease contracted in line of duty in the active military, naval, or air service. 38 U.S.C.A. §§ 1110, 1131. That an injury or disease occurred in service is not enough; there must be chronic disability resulting from that injury or disease. If there is no showing of a resulting chronic condition during service, then a showing of continuity of symptomatology after service is required to support a finding of chronicity. 38 C.F.R. § 3.303(b). Service connection may also be granted for any disease diagnosed after discharge, when all the evidence, including that pertinent to service, establishes that the disease was incurred in service. 38 C.F.R. § 3.303(d). The term "chronic disease," whether as manifest during service or manifest to a compensable degree within a presumptive window following service, applies only to those disabilities listed in 38 U.S.C.A. § 1101 and 38 C.F.R. § 3.309(a). Walker v. Shinseki, No. 2011-7184, slip op. at 13 (U.S. Fed. Cir. Feb. 21, 2013). Service connection for certain diseases, such as arthritis, may be also be established on a presumptive basis by showing that it manifested itself to a degree of 10 percent or more within one year from the date of separation from service. 38 C.F.R. §§ 3.307(a)(3), 3.309(a). In order to establish entitlement to service connection for a disability, the Veteran must show: (1) the existence of a present disability; (2) in-service incurrence or aggravation of a disease or injury; and (3) a causal relationship between the present disability and the disease or injury incurred or aggravated during service. Shedden v. Principi, 381 F.3d 1163, 1166-67 (Fed. Cir. 2004). In determining whether service connection is warranted for a disability, 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 the claim, in which case the claim is denied. See 38 U.S.C.A. § 5107(b) (West 2002); 38 C.F.R. § 3.102 (2012). In considering the evidence of record under the laws and regulations as set forth above, the Board concludes that the Veteran is not entitled to service connection for a bilateral knee disorder. A January 1963 enlistment examination documented a normal evaluation of the lower extremities. In an associated report of medical history, the Veteran denied having, or having a history of, arthritis or rheumatism; bone, joint, or other deformity; or a "trick" or locked knee. A January 1967 separation examination also documented a normal evaluation of the lower extremities. In an associated report of medical history, the Veteran again denied having, or having a history of, arthritis or rheumatism; bone, joint, or other deformity; or a "trick" or locked knee. During a January 2004 VA psychiatry evaluation, the Veteran complained of knee pain. In a January 2004 statement, the Veteran's employer indicated that the Veteran took as much as one week of time off from work at a time when his knees were bothering him. In a February 2004 VA treatment note, it was documented that the Veteran complained of bilateral knee pain. In a statement received by VA in March 2004, the Veteran reported that he was injured when he was thrown from a tank in October 1965 in Vietnam. He reported that the base was attacked by Viet Cong and stated that he was riding on a tank to counterattack and drive the attackers toward Danang Bay. He indicated that, during the chase, the tank that he was riding on made a sudden, high speed turn which swung the gun turret and knocked him off of the tank. He indicated that he landed on top of some debris and bruised his back and legs. Additionally, he reported that he had other injuries to his knees from the "physical wear and tear from jumping from helicopters, humping 80 pound field transport packs..., and being constantly wet for 9 months while in Vietnam..." In a March 2004 private treatment note, the Veteran reported that he had arthritis in his knees. He indicated that he was originally diagnosed with knee problems in the 1970s. An examination of the knees revealed crepitus. The diagnosis was knee pain related to osteoarthritis. March 2004 private x-rays of the bilateral knees showed minimal osteoarthritis in the right knee and an unremarkable left knee. In a statement received by VA in April 2004, the Veteran reported that he was thrown from a truck on the runway at Naval Air Facility in Atsugi, Japan. He stated that he was evacuated from a plane when the brakes caught fire and loaded onto a truck with wooden side and rear rails for a ride to the terminal. He noted that the truck was "not equipped to carry personnel" and had no seats. He also indicated that he was wearing an 80 pound field transport pack and carrying his rifle because he was on his way to join his unit for cold weather training at Mount Fuji. He reported that the driver of the truck made a high speed U- turn on the runway, throwing everyone to one side of the bed of the truck, and the side rail broke. He stated that he fell on his back, and he believed the incident was a "contributing factor" to his current back problems. He did not report that he injured his knees during the accident. In a May 2004 VA treatment note, the Veteran complained of knee pain from osteoarthritis. In a September 2004 VA treatment note, the Veteran complained of right knee pain. During a September 2004 VA posttraumatic stress disorder (PTSD) examination, the Veteran reported that he was "never physically injured" during his Vietnam service. In a statement received by VA in November 2004, J. L. reported that he was also a passenger on the tank that threw the Veteran to the ground in 1965. He reported that the tank was carrying approximately ten Marines at the time of the accident. He stated that the tank turned at a 90 degree angle and the turret rotated hard to the left, turning racks of five gallon water cans around it. He reported that the water cans struck the Veteran in the knees and threw them 20 to 30 feet into the gravel. He reported that he had broken knee caps after being thrown from the tank and he remembered that the Veteran was injured too. He indicated that their knees and hands were "extremely swollen" from the impact of landing at a high speed while wearing full combat gear. He reported that they wrapped their legs and knees and were treated by several corpsmen, but "going to Charlie Medical was out of the question" due to a shortage of men in their company and platoon. During a May 2005 private psychiatric evaluation, the Veteran reported that he injured his back when he was thrown from a tank and later when he was thrown from a truck in Vietnam. He did not mention any knee injuries from the accidents. During a December 2005 hearing before the Decision Review Officer (DRO), the Veteran testified that he injured his knees when he was thrown from a tank in Vietnam. With respect to treatment for his knee injuries in service, he stated, "You kind of have to understand the mindset when you are there, especially in the Marine Corps in the 60's. If I could get up and out of my rack in the morning and do my job, that is what I did. You try to keep things like going to see the corpsman at a minimum... I was never like in a hospital there. I am not really sure since we were the first full Marine division or any military division that went to Vietnam that was even set up yet." With respect to treatment for his knees following service, he reported that he did not seek continuous treatment because "they really didn't bother" him. He indicated that his knee pain "started showing up" in the early 1970s. During a February 2006 private orthopedic evaluation for a workers' compensation claim pertaining to a left shoulder injury, the Veteran reported that he injured his knees in Vietnam. During a September 2006 VA joints examination, the Veteran indicated that he injured his knees during service. He denied any definite trauma with the exception of a chronic, nonspecific injury. An examination of the bilateral knees was unremarkable with the exception of crepitus with passive range of motion in the right knee. X-rays of the left knee revealed tricompartmental osteoarthritis and prepatellar soft tissue swelling. A magnetic resonance imaging (MRI) study of the right knee also showed a small effusion with minor tricompartmental degenerative changes, degeneration of the anterior horn medial meniscus and anterior horn of the lateral meniscus, and a tear involving the posterior horn of the medial meniscus. The diagnosis was bilateral knee pain with tricompartmental osteoarthritis of both knees and a medial meniscus tear and degeneration of the right knee. The examiner noted that these degenerative changes were at least as likely as not related to chronic nonspecific service-related trauma or physical training. She noted that non-specific recurrent trauma, such as marching and running, frequently led to degenerative changes of the major joints of the lower extremities. In a December 2006 VA addendum opinion, the examiner provided the following: Review of the [claims] file again shows an around 20-page detailed report by the [V]eteran which details his activities while in service. These activities include constantly running patrols, ambushes, security details, and large- scale operations. He specifically gives details of an operation where he was blown off of a tank and landed on top of debris and bruised his back and legs, and gives multiple accounts to the same effect, where he was in the middle of gun fire, and he was running to escape being shot, or chasing the enemy, or avoiding explosions. He also specifically gives account of injuries to his back and knees suffered in Vietnam. Physical wear and tear from jumping from helicopters, from humping 80-pound field transport packs on his back, could very well lead to degenerative changes over following years. The VA examiner confirmed that, therefore, it was her opinion that the degenerative changes noted were as least as likely as not secondary to the service-related physical activities. During a March 2007 VA physical medicine rehabilitation consultation, the Veteran reported that he injured his back on two instances during service when he was knocked off of a tank and when he was thrown from a truck. He did not mention injuring his knees during these incidents. He noted that his current service-connected low back symptoms included pain that radiated to his hip area and down to his knees. He indicated that he had osteoarthritis and a possible tear in his right knee. The diagnoses included osteoarthritis of both knees. September 2009 VA x-rays of the bilateral knees revealed normal knees, bilaterally. During a November 2012 VA general medical examination, the examiner noted that the Veteran denied a specific knee injury. She indicated that a review of the claims file did not show a knee injury and noted that September 2009 x-rays showed normal knees. The Veteran reported that his knee symptoms remained unchanged since 2009; therefore, the examiner did not order new x-rays. She also observed that the Veteran used a cane primarily to support his back. The examiner opined that the Veteran's claimed bilateral knee disorder was less likely than not incurred in or caused by the claimed in-service injury, event, or illness. She indicated that there was no knee injury in service. She further noted that x-rays of the knees were normal and did not show evidence of arthritis. She also reported that her examination of the knees was largely unremarkable; therefore, she was unable to make a diagnosis. On review, the Board concludes that the Veteran's current bilateral knee disorder did not manifest in service or within one year after separation from service. The Veteran's service treatment records do not document any complaints, treatment, or diagnosis pertaining to his knees. With respect to the Veteran's statements that he injured his knees in service, the Board notes that he is competent to report his experience and symptoms in service and thereafter. While lay persons are generally not competent to offer evidence which requires medical knowledge, such as opinions regarding medical causation or a diagnosis, they may provide competent testimony as to visible symptoms and manifestations of a disorder. Jones v. Brown, 7 Vet. App. 134, 137 (1994); Layno v. Brown, 6 Vet. App. 465, 469 (1994); Barr v. Nicholson, 21 Vet. App. 303 (2007); Buchanan v. Nicolson, 451 F.3d 1331 (Fed. Cir. 2006). A veteran can attest to factual matters of which he or had had first-hand knowledge, e.g., experiencing pain in service, reporting to sick call, being placed on limited duty, and undergoing physical therapy. See Washington v. Nicholson, 19 Vet. App. 362, 368 (2005). The Federal Circuit has held that lay evidence is one type of evidence that must be considered, if submitted, when a veteran seeks disability benefits, and competent lay evidence can be sufficient in and of itself for proving the existence of a chronic disease. See Buchanan, 451 F.3d at 1335; 38 C.F.R. §§ 3.303(a), 3.307(b). The Board, however, retains the discretion to make credibility determinations and otherwise weigh the evidence submitted, including lay evidence. Buchanan, 451 F.3d at 1336. Once evidence is determined to be competent, the Board must determine whether such evidence is also credible. See Layno v. Brown, 6 Vet. App. 465 (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 Barr v. Nicholson, 21 Vet. App. 303 (2007). In this case, the Board finds that the Veteran is competent to state that he has had knee problems since his military service. However, his allegations are inconsistent with the contemporaneous record. As previously discussed, there is no evidence of any complaints, treatment, or diagnosis in service, and his lower extremities were documented as being within normal limits at the time of his separation from service. As such, there is actually affirmative evidence showing that he did not have a knee disorder at the time of his separation from service. Additionally, the Veteran has actually admitted that his bilateral knee pain manifested in the early 1970s, following his separation from service. In fact, during a December 2005 DRO hearing, he testified that he did not seek continuous treatment for his knees following service because "they really didn't bother" him. He indicated that his knee pain "started showing up" in the early 1970s. Thus, the Veteran himself has indicated that he did not have any symptomatology or problems during his military service or within one year thereafter. The Board also finds that the Veteran's contentions that he injured his knees after being thrown from a tank and/or a truck during service are inconsistent throughout the record. The Veteran also submitted buddy statements from a fellow Marine in support of his claim that he injured his knees when he was thrown from a tank in Vietnam. However, during a September 2004 VA posttraumatic stress disorder (PTSD) examination, the Veteran himself reported that he was "never physically injured" during his Vietnam service. Likewise, during the November 2012 VA examination, he denied any specific knee injuries. Additionally, in statements dated in April 2004, May 2005, and March 2007, he provided detailed statements discussing the tank and truck accidents; however, in the statements, he alleged that he injured his low back and did not mention any knee injuries. For these reasons, the Board finds that the Veteran's reported history regarding the onset of his bilateral knee disorder to be not credible. Furthermore, there is no documented evidence of any complaints pertaining to his knees until he complained of knee pain during a January 2004 VA psychiatry evaluation. A prolonged period without medical complaint can be considered, along with other factors concerning a claimant's health and medical treatment during and after military service, as evidence of whether an injury or a disease was incurred in service which resulted in any chronic or persistent disability. See Maxson v. Gober, 230 F.3d 1330, 1333 (Fed. Cir. 2000). Thus, the weight of the evidence of record show that his current bilateral knee disorder did not manifest in service or for many decades thereafter. Contemporaneous evidence has greater probative value than history as reported by the Veteran. See Curry v. Brown, 7 Vet. App. 59, 68 (1994). To the extent that the Veteran has opined that his current knee disorder is related to his military service, the Board notes that lay witnesses are competent to opine as to some matters of diagnosis and etiology. The Board must determine on a case by case basis whether a Veteran's particular disability is the type of disability for which lay evidence is competent. See Davidson v. Shinseki, 581 F.3d 1313, 1316 (Fed. Cir. 2009); Kahana v. Shinseki, 24 Vet. App. 428, 433, n. 4 (2011). In this case, the Veteran's testimony indicating that he has a current knee disorder that developed years later as a result of an earlier in-service injury is testimony as to an internal medical process, which extends beyond an immediately observable cause-and-effect relationship that is of the type that the courts have found to be beyond the competence of lay witnesses. Compare Jandreau v. Nicholson, 492 F.3d 1372, 1376 (Fed. Cir. 2007) (lay witness capable of diagnosing dislocated shoulder); Barr v. Nicholson, 21 Vet. App. 303, 308-9 (2007) (lay testimony is competent to establish the presence of varicose veins); with Clemons v. Shinseki, 23 Vet. App. 1, 6 (2009) ("It is generally the province of medical professionals to diagnose or label a mental condition, not the claimant."); Woehlaert v. Nicholson, 21 Vet. App. 456, 462 (2007) (unlike varicose veins or a dislocated shoulder, rheumatic fever is not a condition capable of lay diagnosis); Jandreau, 492 F.3d at 1377, n. 4 ("sometimes the layperson will be competent to identify the condition where the condition is simple, for example a broken leg, and sometimes not, for example, a form of cancer"). Nevertheless, even assuming that the Veteran is competent to opine on this medical matter, the Board finds that the specific, reasoned opinion of the November 2012 VA examiner is of greater probative weight than the Veteran's more general lay assertions. It is the responsibility of the Board to assess the credibility and weight to be given the evidence. See Hayes v. Brown, 5 Vet. App. 60, 69-70 (1993) (citing Wood v. Derwinski, 1 Vet. App. 190, 192-93 (1992)). The probative value of medical evidence is based on the provider's knowledge and skill in analyzing the data, and the medical conclusion the provider reaches; as is true of any evidence, the credibility and weight to be attached to medical opinions are within the province of the Board. See Guerrieri v. Brown, 4 Vet. App. 467, 470-71 (1993). When reviewing such medical opinions, the Board may appropriately favor the opinion of one competent medical authority over another. See Owens v. Brown, 7 Vet. App. 429, 433 (1995). However, the Board may not reject medical opinions based on its own medical judgment. Obert v. Brown, 5 Vet. App. 30 (1993); see also Colvin v. Derwinski, 1 Vet. App. 171 (1991). In assessing medical opinions, the failure of the physician to provide a basis for his opinion goes to the weight or credibility of the evidence in the adjudication of the merits. See Hernandez-Toyens v. West, 11 Vet. App. 379, 382 (1998). Other factors for assessing the probative value of a medical opinion are the physician's access to the claims file and the thoroughness and detail of the opinion. See Prejean v. West, 13 Vet. App. 444, 448-49 (2000). However, a medical opinion may not be discounted solely because the examiner did not review the claims file. Nieves-Rodriguez v. Peake, 22 Vet. App. 295, 304 (2008). In the September 2006 VA opinion, the examiner opined that the degenerative changes in the Veteran's knees were at least as likely as not related to chronic nonspecific service-related trauma or physical training. She noted that non-specific recurrent trauma such as marching and running frequently led to degenerative changes of the major joints of the lower extremities. In a December 2006 VA addendum opinion, the examiner provided the following: Review of the [claims] file again shows an around 20-page detailed report by the [V]eteran which details his activities while in service. These activities include constantly running patrols, ambushes, security details, and large- scale operations. He specifically gives details of an operation where he was blown off of a tank and landed on top of debris and bruised his back and legs, and gives multiple accounts to the same effect, where he was in the middle of gun fire, and he was running to escape being shot, or chasing the enemy, or avoiding explosions. He also specifically gives account of injuries to his back and knees suffered in Vietnam. Physical wear and tear from jumping from helicopters, from humping 80-pound field transport packs on his back, could very well lead to degenerative changes over following years. The September 2006 VA examiner confirmed that, therefore, it was her opinion that the degenerative changes noted were as least as likely as not secondary to the Veteran's reported service-related physical activities. The September 2006 VA examiner based her opinions on the Veteran's reported history. The Board notes that a medical opinion formed on the basis of the Veteran's reported medical history cannot be rejected without the Board first finding that the Veteran's allegations are not credible. Coburn v. Nicholson, 19 Vet. App. 427, 432 (2005); Buchanan v. Nicholson, 451 F.3d 1331 (Fed. Cir. 2006) (holding the Board cannot determine that a Veteran's statements lack credibility merely based on a lack of such documentation in the service treatment records). Here, as discussed above, the Board finds reason to doubt the credibility of the Veteran's statements. The Board finds the November 2012 VA examiner's opinion to be more probative than the September 2006 VA examiner's opinion. The examiner reviewed the Veteran's reported history as well as the information and evidence in the claims folder, and she provided a thorough and adequate rationale that is supported by the evidence of record. Indeed, the examiner specifically discussed the lack of documentation of any knee injuries in the service treatment records. Moreover, she found that the evidence did not support a current diagnosis pertaining to the bilateral knees. On the other hand, the September 2006 VA examiner did not discuss the fact that the Veteran's service treatment records were negative for any complaints, treatment, or diagnosis of any bilateral knee injuries, including the affirmative findings at the time of the separation examination that revealed normal lower extremities. She also did not acknowledge the decades-long evidentiary gap between the Veteran's separation from service and his first documented complaints regarding his knee pain. Nor did she provide a thorough rationale, such as an explanation of how degenerative changes manifest over following years after initial physical trauma. The value of a physician's statement is dependent, in part, upon the extent to which it reflects "clinical data or other rationale to support his opinion." Bloom v. West, 12 Vet. App. 185, 187 (1999). Thus, a medical opinion is inadequate when it is unsupported by clinical evidence. Black v. Brown, 5 Vet. App. 177, 180 (1995). See also Knightly v. Brown, 6 Vet. App. 200 (1994); Miller v. West, 11 Vet. App. 345, 348 (1998) (medical opinions must be supported by clinical findings in the record and conclusions of medical professionals which are not accompanied by a factual predicate in the record are not probative medical opinions). In this case, and based on the foregoing, the Board attaches the greatest probative weight to the opinion of the November 2012 VA examiner who had the benefit and review of all pertinent medical records and who provided a rationale supported by the record. As the Veteran has a diagnosis of arthritis, section 3.303(b) is applicable. However, arthritis was not diagnosed or identified during service, and the separation examination was normal. Thus, chronicity may be legitimately questioned. Walker, supra. In fact, he did not seek treatment for knee pain until more than 35 years after service. Such evidence clearly establishes that arthritis was not manifest during service or within one year of separation. The evidence also establishes that there is no continuity of symptomatology in regard to arthritis. Therefore, the preponderance of the evidence is against the claim for entitlement to service connection for a bilateral knee disorder. The benefit-of-the-doubt doctrine is therefore not for application, and the claim must be denied. See 38 U.S.C.A. § 5107(b); 38 C.F.R. § 3.102; see also Fagan v. Shinseki, 573 F.3d 1282, 1287 (Fed. Cir. 2009). ORDER An initial compensable evaluation for bilateral hearing loss is denied. Service connection for a bilateral knee disorder is denied. REMAND In this case, the Veteran contends that his current skin rash disorder, variously diagnosed as eczema or psoriasis, is a result of exposure to herbicides during service in Vietnam. As part of the duty to assist a Veteran in developing the facts and evidence concerning a service connection claim, VA must provide an examination for a medical nexus opinion when there is: (1) competent evidence of a current disability or persistent or recurrent symptoms of a disability; (2) evidence establishing that an event, injury, or disease occurred in service or establishing certain diseases manifested during an applicable presumptive period for which he qualifies; and (3) an indication that the disability or persistent or recurrent symptoms of a disability may be associated with his service or a service-connected disability; but (4) insufficient competent medical evidence on file for VA to make a decision on the claim. McLendon v. Nicholson, 20 Vet. App. 79 (2006); see also 38 U.S.C.A. § 5103A (d)(2); 38 C.F.R. § 3.159(c)(4). A review of the service treatment records shows that the Veteran was treated for a skin infection from March 1969 to April 1966. The Veteran also has current diagnoses of psoriasis and eczema and is competent to report experiencing a skin rash since service. However, it is unclear whether the current diagnosis is related to the Veteran's military service, to include exposure to herbicide agents. Therefore, the Board must obtain a medical opinion before adjudicating this claim. See McLendon v. Nicholson, 20 Vet. App. 79 (2006); 38 U.S.C.A. § 5103A (d)(2); 38 C.F.R. § 3.159(c)(4). The Board also notes that the Virtual VA paperless claims file contains a statement from the Veteran's representative that includes the issue of entitlement to an initial evaluation in excess of 50 percent for PTSD. The RO previously determined that the issue was not on appeal. Historically, the issue was included in a February 2007 statement of the case (SOC); a March 2007 VA Form 9, Appeal to the Board; a subsequent SSOC dated in July 2009; and a second VA Form 9 dated in August 2009 in which the Veteran indicated that he wanted to appeal all of the issues listed on the SOC and any SSOC that he received. Thereafter, in September 2009, the Veteran submitted another VA Form 9 dated in January 2009 that did not include the issue. Rather, he stated, "I am only appealing these issues: ec[z]ema, claimed as a skin condition[;] residuals of injury, right [and] left knees[;] and hearing loss being held at 0%." However, he did not specifically state that he wanted to withdraw his claim for a higher initial evaluation for PTSD. Thereafter, the RO issued an SSOC in April 2010 that did not include the issue, and the Veteran submitted a fourth VA Form 9 dated in May 2010 that indicated that he wanted to appeal all of the issues listed on the SOC and any SSOC that he received. Thus, it is unclear as to whether the Veteran intended to withdraw the claim or whether he wanted to continue with the already perfected appeal. Therefore, clarification from the Veteran is necessary prior to proceeding with the adjudication of this claim. Moreover, if the Veteran indicates an intent to proceed with his claim for a higher initial evaluation for PTSD, the Board finds that additional development is necessary to ensure that is ready for adjudication. Accordingly, the case is REMANDED for the following action: 1. The RO/AMC must contact the Veteran to determine if he intends to proceed with his claim of entitlement to a higher initial evaluation for PTSD. If he wishes to withdraw the appeal, he must specifically indicate his intent in writing. 2. The RO/AMC should request that the Veteran identify the names, addresses, and approximate dates of treatment for any VA and non-VA health care providers who have treated him for his skin disorder, as well as PTSD if he does not withdraw that issue from the appeal. A specific request should be made for any outstanding VA treatment records dated after March 2012. After obtaining any necessary authorization from the Veteran, the RO/AMC should attempt to obtain copies of pertinent treatment records identified by the Veteran in response to this request that are not already contained in the claims file. Any negative search result should be noted in the record. 3. After the foregoing development has been completed, the RO/AMC should schedule the Veteran for a VA examination to determine the nature and etiology of any skin disorder that may be present. The examiner is requested to review all pertinent records associated with the claims file, including the Veteran's service treatment records, post-service medical records, and statements. It should be noted that the Veteran is competent to attest to observable symptomatology. If there is a medical basis to support or doubt the history provided by the Veteran, the examiner should provide a fully reasoned explanation. It should also be noted that the Veteran served in the Republic of Vietnam during the Vietnam era and is presumed to have been exposed during such service to certain herbicide agents, including Agent Orange. The examiner is requested to review the claims file and to identify any current skin disorder. For each diagnosis identified, the examiner should discuss whether it is at least as likely as not that the disorder manifested in service or is otherwise causally or etiologically related to his military service, to include exposure to herbicide agents. (The term "at least as likely as not" does not mean within the realm of medical possibility, but rather that the medical evidence both for and against a conclusion is so evenly divided that it is as medically sound to find in favor of conclusion as it is to find against it.) A clear rationale for all opinions would be helpful and a discussion of the facts and medical principles involved would be of considerable assistance to the Board. Because it is important "that each disability be viewed in relation to its history [,]" 38 C.F.R. § 4.1, copies of all pertinent records in the appellant's claims file, or in the alternative, the claims file, must be made available to the examiner for review. 4. If the issue of entitlement to a higher initial evaluation for PTSD remains on appeal, the Veteran should be afforded a VA examination to ascertain the current severity and manifestations of that disability. Any and all studies, tests, and evaluations deemed necessary by the examiner should be performed. The examiner is requested to review all pertinent records associated with the claims file and to comment on the severity of the Veteran's service-connected PTSD. The examiner should report all signs and symptoms necessary for rating the Veteran's PTSD under the General Rating Formula for Mental Disorders. The findings of the examiner should address the level of social and occupational impairment attributable to the Veteran's PTSD. In particular, he or she should indicate whether the Veteran has occupational and social impairment with reduced reliability and productivity; occupational and social impairment with deficiencies in most areas, such as work, school, family relations, judgment, thinking, or mood; or, total occupational and social impairment. A clear rationale for all opinions would be helpful and a discussion of the facts and medical principles involved would be of considerable assistance to the Board. Because it is important "that each disability be viewed in relation to its history [,]" 38 C.F.R. § 4.1, copies of all pertinent records in the appellant's claims file, or in the alternative, the claims file, must be made available to the examiner for review. 5. After the above development has been completed, the RO/AMC should review the claims file to ensure that the aforementioned development and remand instructions have been fully and properly executed. Any noncompliance found should be rectified with the appropriate development. 6. Thereafter, the RO/AMC should readjudicate the Veteran's claim of entitlement to service connection for a left foot disorder. If the benefit sought on appeal remains denied, the Veteran and his representative should be furnished a SSOC and afforded the opportunity to review the claims file and submit written arguments on the Veteran's behalf, to include, as appropriate, a VA Form 646, or the equivalent, before the record is returned to the Board for further appellate review, if appropriate. The Veteran has the right to submit additional evidence and argument on the matter 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. 2012). ______________________________________________ JESSICA J. WILLS Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
