REPRESENTATION Appellant represented by: Veterans of Foreign Wars of the United States ATTORNEY FOR THE BOARD T. L. Anderson, Associate Counsel INTRODUCTION The Veteran had active service from January 1942 to October 1945. This matter previously came before the Board of Veterans' Appeals (Board) from November 2005 and March 2009 rating decisions by the above Department of Veterans Affairs (VA) Regional Office (RO). FINDINGS OF FACT 1. On January 15, 2009, the Board issued a decision denying reinstatement of service connection for asthma, and referred to the RO a claim of CUE in an October 1960 rating decision which had severed service connection for asthma. 2. The issues of reinstatement of service connection for asthma and whether there was CUE in the October 1960 rating decision are sufficiently related such that adjudication of the two issues together would ensure due process. 3. In an October 1960 rating decision, the RO severed service connection for asthma. The Veteran did not appeal that decision, and it became final. 4. The October 1960 rating decision, which severed service connection for asthma, was reasonably supported by the evidence then of record; it is not shown that the applicable statutory or regulatory provisions existing at that time were ignored or incorrectly applied; and the appellant has failed to allege any kind of error of fact or law in that decision which, when called to the attention of later reviewers, compels the conclusion, as to which reasonable minds could not differ, that the result would have been manifestly different but for the error. 5. An August 2005 rating decision denied reinstatement of service connection for asthma, and the Veteran did not appeal that decision. 6. The evidence associated with the claims file subsequent to the August 2005 decision was not previously submitted for consideration, relates to an unestablished fact necessary to establish the claim, and raises a reasonable possibility of substantiating the claim, so as to warrant reopening the claim. 7. The competent and probative evidence preponderates against a finding that the Veteran's has a current diagnosis of asthma, or that asthma is due to any incident or event in military service. CONCLUSIONS OF LAW 1. The criteria for vacating the Board decision issued on January 15, 2009, have been met. 38 U.S.C.A. § 7104(a) (West 2002 & Supp. 2010); 38 C.F.R. § 20.904 (2010). 2. The October 1960 rating decision severing service connection for asthma is final. 38 U.S.C.A. § 7105(c) (West 2002 & Supp. 2010); 38 C.F.R. §§ 3.104, 3.160(d), 20.302, 20.1103 (2010). 3. The October 1960 rating decision which severed service connection for asthma was not clearly and unmistakably erroneous. 38 U.S.C.A. §§ 5109A, 7105 (West 2002 & Supp. 2010); 38 C.F.R. § 3.105(a) (2010). 4. The August 2005 rating decision, which denied reinstatement of service connection for asthma, is final. 38 U.S.C.A. § 7105 (West 2002 & Supp. 2010); 38 C.F.R. § 20.302 (2010). 5. The evidence received subsequent to the August 2005 rating decision is new and material, and the claim for service connection for asthma is reopened. 38 U.S.C.A. § 5108 (West 2002 & Supp. 2010); 38 C.F.R. § 3.156 (2010). 6. Asthma was not incurred in or aggravated by service. 38 U.S.C.A. § 1101, 1110, 1154, 5103(a), 5103A, 5107 (West 2002 & Supp. 2010); 38 C.F.R. §§ 3.102, 3.159, 3.303, 3.304 (2010). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS I. Duty to Notify and Assist The Veterans Claims Assistance Act of 2000 (VCAA) enhanced VA's duty to notify and assist claimants in substantiating their claims for VA benefits, as codified in pertinent part at 38 U.S.C.A. §§ 5103, 5103A, 5107, 5126 (West 2002 & Supp. 2010); 38 C.F.R. §§ 3.102, 3.159, 3.326(a) (2010). Upon receipt of a complete or substantially complete application for benefits, VA is required to notify the claimant and his representative of any information, and any medical or lay evidence, that is necessary to substantiate the claim. 38 U.S.C.A. § 5103(a); 38 C.F.R. § 3.159(b); Quartuccio v. Principi, 16 Vet. App. 183 (2002). Proper notice from 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; and (3) that the claimant is expected to provide. 38 C.F.R. § 3.159(b)(1) (2010). This notice must be provided prior to an initial unfavorable decision on a claim by the RO. Mayfield v. Nicholson, 444 F.3d 1328 (Fed. Cir. 2006); Pelegrini v. Principi, 18 Vet. App. 112 (2004). In addition, the decision of the U.S. Court of Appeals for Veterans Claims (Court) in Dingess v. Nicholson, 19 Vet. App. 473 (2006) requires more extensive notice in claims for compensation, e.g., as to potential downstream issues such as disability rating and effective date. In claims to reopen, VA must both notify a claimant of the evidence and information that is necessary to reopen the claim and notify the claimant of the evidence and information that is necessary to establish entitlement to the underlying claim for the benefit that is being sought. Kent v. Nicholson, 20 Vet. App. 1 (2006). To satisfy this requirement, the Secretary is required to look at the bases for the denial in the prior decision and to provide the claimant with a notice letter that describes what evidence would be necessary to substantiate those elements required to establish service connection that were found insufficient in the previous denial. If complete notice is not provided until after the initial adjudication, such a timing error can be cured by subsequent legally adequate VCAA notice, followed by readjudication of the claim, as in a Statement of the Case (SOC) or Supplemental SOC (SSOC). Moreover, where there is an uncured timing defect in the notice, subsequent action by the RO which provides the claimant a meaningful opportunity to participate in the processing of the claim can prevent any such defect from being prejudicial. Mayfield v. Nicholson, 499 F.3d 1317, 1323-24 (Fed. Cir. 2007); Prickett v. Nicholson, 20 Vet. App. 370, 376 (2006). The U.S. Supreme Court has held that an error in VCAA notice should not be presumed prejudicial, and that the burden of showing harmful error rests with the party raising the issue, to be determined on a case-by-case basis. Shinseki v. Sanders, 129 S. Ct. 1696 (2009). In this case, the appellant has not demonstrated any prejudicial or harmful error in VCAA notice, and, as discussed herein, the Board has identified none. The U.S. Court of Appeals for Veterans Claims has held that the statutory and regulatory provisions pertaining to VA's duty to notify and to assist under the VCAA do not apply to allegations of clear and unmistakable error in prior RO or Board decisions, because a CUE motion is not a claim or an appeal, but is a collateral attack upon a previous final decision. Livesay v. Principi, 15 Vet. App. 165, 178 (2001) (en banc); Simmons v. Principi, 17 Vet.App. 104, 109 (2003). With regard to the service connection claim, VA sent the Veteran a letter in October 2005 informing him of the types of evidence needed to substantiate his claim and its duty to assist him in substantiating his claim under the VCAA. The letter included attachments which informed him that VA would assist him in obtaining evidence necessary to support his claim, such as medical records, employment records, or records from other Federal agencies. He was advised that it is his responsibility to provide or identify, and furnish authorization where necessary for the RO to obtain, any supportive evidence pertinent to his claim. See 38 C.F.R. § 3.159(b)(1). Although no longer required, the appellant was also asked to submit evidence and/or information in his possession to the RO. The Board also notes that a June 2005 letter sent in response to a previous claim for service connection for asthma explained the bases for the severance of service connection for asthma and what type of evidence would be considered new and material. Finally, the April 2006 SSOC included a section which describes how VA determines disability ratings and effective dates. The Board acknowledges that the content of the October 2005 letter did not fully comply with the requirements of 38 U.S.C.A. § 5103(a) and 38 C.F.R. § 3.159(b), as later amended, regarding VA's duty to notify and assist. However, the Board finds that any error in notice is non-prejudicial. Although the Veteran did not receive Dingess notice until after initial adjudication of the claim (as the initial rating decision occurred prior the Court's ruling in Dingess), it is clear that he was provided with the opportunity to participate in the processing of his claim, so as to render any defect in notice non-prejudicial. For example, the November 2005 rating decision, January 2006 SOC, and April and October 2006 SSOCs explained the basis for the RO's action, and the SOC and SSOCs provided him with additional 60-day periods to submit more evidence. In addition, the Veteran has demonstrated through his correspondence and submission of additional evidence that he was aware of the type of evidence required to substantiate his claim. Moreover, the benefit being sought is not being granted in this case, so the Board will not reach the issue of disability rating or effective date discussed by the Court in Dingess. It appears that all obtainable evidence identified by the Veteran relative to his claim has been obtained and associated with the claims file, and that neither he nor his representative has identified any other pertinent evidence, not already of record, which would need to be obtained for a fair disposition of this appeal. It is the Board's conclusion that the Veteran has been provided with every opportunity to submit evidence and argument in support of his claim, and to respond to VA notices. Additionally, the Veteran has demonstrated knowledge of, and has acted upon, the information and evidence necessary to substantiate the pending claim. See, e.g., Dalton v. Nicholson, 21 Vet. App. 23, 30 (2007) (Court was convinced that the appellant and representative had demonstrated actual knowledge of the information and evidence necessary to establish the claim). Moreover, the Veteran has not identified any evidence which he would have submitted if Dingess notice had been provided earlier. With regard to VA's duty to assist, VA obtained the Veteran's service treatment records (STRs) and was afforded a VA examination in July 2006. The Veteran also submitted private treatment records. Accordingly, we find that VA has satisfied its duty to assist the Veteran in apprising him as to the evidence needed, and in obtaining evidence pertinent to his claim under the VCAA. Therefore no useful purpose would be served in remanding this matter for yet more development. Such a remand would result in unnecessarily imposing additional burdens on VA, with no additional benefits flowing to the Veteran. The Court of Appeals for Veteran Claims has held that such remands are to be avoided. See Soyini v. Derwinski, 1 Vet. App. 540, 546 (1991); Sabonis v. Brown, 6 Vet. App. 426, 430 (1994). II. Vacatur On January 15, 2009, the Board issued a decision that reopened and denied the Veteran's claim of entitlement to reinstatement of service connection for asthma. In the Introduction to that decision, the Board also noted that the Veteran's representative had raised a contention, in his December 2008 Informal Hearing Presentation (IHP), that the October 1960 rating decision which had severed service connection for asthma was a product of clear and unmistakable. Since the RO had not adjudicated the CUE issue, the issue of whether the 1960 rating decision had constituted CUE was referred by the Board to the RO. Subsequently, the RO issued a rating decision in March 2009 in which it found that the October 1960 rating decision was not clearly and unmistakably erroneous. The Veteran perfected his appeal as to that issue, and it is now before the Board. In October 2010, the Veteran's representative submitted a request that the Board's January 2009 decision be vacated, and that the issues of whether the October 1960 rating decision constituted CUE and whether new and material evidence had been received to reopen a claim of entitlement to reinstatement of service connection for asthma be considered together. In this motion, the Veteran's representative argued that the two issues are inextricably intertwined, citing to Smith v. Gober, 236 F.3d 1370, 1373 (Fed. Cir. 2001) (noting that where the facts underlying separate claims are "intimately connected," the interests of judicial economy and avoidance of piecemeal litigation require that the claims be adjudicated together) and Harris v. Derwinski, 1 Vet. App. 180, 183 (1991) (two or more issues are inextricably intertwined if the resolution of one could have significant impact on the other). An appellate decision may be vacated by the Board at any time upon the request of the appellant or his representative, or on the Board's own motion, when there has been a denial of due process. 38 C.F.R. 20.904 (2010). In deference to the representative's thoroughly articulated argument , and in order to assure a full measure of due process to the Veteran's claim and appeal, the Board has decided to vacate our January 15, 2009, decision and address the issues of CUE and reinstatement of service connection together. Under 38 U.S.C.A. § 7252, only a decision of the Board of Veterans' Appeals is appealable to the United States Court of Appeals for Veterans Claims (Court). This vacatur is in the nature of a preliminary order and does not constitute a decision of the Board on the merits of the appeal. 38 C.F.R. § 20.1100(b) (2010). The merits of the issue set forth above are considered de novo in the decision below. III. Whether Severance of Service Connection Constituted CUE A. Applicable Law Pursuant to 38 C.F.R. § 3.104(a), "[a] decision of [an RO] shall be final and binding on all field offices of [VA] as to conclusions based on the evidence on file at the time VA issues written notification in accordance with 38 U.S.C. § 5104." 38 C.F.R. § 3.104(a). Such a final decision may be subject to revision, however, in the presence of clear and unmistakable error, as described in 38 C.F.R. § 3.105. Thus, a prior final RO decision will be accepted as correct unless CUE can be shown. 38 C.F.R. § 3.105(a). Clear and unmistakable (CUE) is defined as "a very specific and rare kind of 'error.' It is the kind of error, of fact or of law, that when called to the attention of later reviewers compels the conclusion, to which reasonable minds could not differ, that the result would have been manifestly different but for the error." Fugo v. Brown, 6 Vet. App. 40, 43 (1993) (emphasis in original). The Court has propounded a three-pronged test to determine whether CUE was present in a prior determination: (1) either the correct facts, as they were known at the time, were not before the adjudicator (i.e., more than simple disagreement as to how the facts were weighed or evaluated) or the statutory or regulatory provisions extant at the time were incorrectly applied; (2) the error must be undebatable and of the sort which, had it not been made, would have manifestly changed the outcome at the time it was made; and (3) a determination that there was CUE must be based on the record and law that existed at the time of the prior adjudication in question. Russell v. Principi, 3 Vet. App. 310, 313-14 (1992). If a claimant-appellant wishes to reasonably raise CUE, there must be some degree of specificity as to what the alleged error is and, unless it is the kind of error which, if true, would be CUE on its face, persuasive reasons must be given as to why the result would have been manifestly different but for the alleged error. It must be remembered that there is a presumption of validity to otherwise final decisions, and that where such decisions are collaterally attacked, and a CUE claim is undoubtedly a collateral attack, the presumption is even stronger. Id.; see also Grover v. West, 12 Vet. App. 109, 111- 112 (1999); Daniels v. Gober, 10 Vet. App. 474, 478 (1997); Caffrey v. Brown, 6 Vet. App. 377, 383-384 (1994); Damrel v. Brown, 6 Vet. App. 242, 245 (1994). Generally, CUE exists when either the correct facts, as they were known at the time, were not before the decision maker(s), or the statutory and regulatory provisions extant at the time were incorrectly applied. See 38 C.F.R. § 20.1403(a); Sorakubo v. Principi, 16 Vet. App. 120 (2002). A simple disagreement with how the RO evaluated the facts is not sufficient to raise a valid claim of CUE. Luallen v. Brown, 8 Vet. App. 92, 95 (1995). In addition, the mere misinterpretation of facts does not constitute CUE. See Thompson v. Derwinski, 1 Vet. App. 251, 253 (1991). Moreover, the Court has held that a failure to fulfill the duty to assist does not constitute CUE. See Crippen v. Brown, 9 Vet. App. 412, 424 (1996); Caffrey v. Brown, supra. B. Facts and Analysis The Veteran first filed a claim of entitlement to service connection for asthma in December 1945. He was subsequently afforded a VA examination in May 1946 at which the VA examiner assessed asthma by history only, with attacks occurring every three months on average. Consequently, the RO granted service connection for bronchial asthma in a May 1948 rating decision. In a December 1959 proposed rating decision, the RO advised the Veteran of its intention to sever service connection for that disability. In the October 1960 rating decision now on appeal, the RO determined that the grant of service connection for asthma had been clearly and unmistakably erroneous, and effectuated the proposed severance. The RO found that bronchial had asthma pre- existed the Veteran's service in the Army and there was no evidence showing that the condition was permanently aggravated during service. The Veteran did not file a timely appeal of the severance. Consequently, the October 1960 rating decision became final. See 38 U.S.C.A. § 7105; 38 C.F.R. § 20.302. The Veteran now alleges that the October 1960 rating decision contained CUE. For the reasons discussed below, the Board finds that the October 1960 rating decision severing service connection for asthma was not clearly and unmistakably erroneous. First, the correct facts, as they were known at the time, were available to the RO. The RO had in its possession the Veteran's STRs and the reports of several VA examinations, and cited to that medical evidence in detail in its December 1959 proposed rating decision. There is no contention by the Veteran that the RO did not have access to any pertinent evidence. Rather, the Veteran's representative essentially contended in the December 2008 IHP that the RO did not place enough weight on the entrance examination which was negative for asthma, and that the Veteran's statements regarding his pre-service bout of asthma in November 1941 did not constitute clear and unmistakable evidence to rebut the presumption of soundness on entry into service. In its 1960 rating decision, the RO determined that the Veteran's statements to the effect that he had received treatment for and was diagnosed with asthma in November 1941, prior to entering active service, constituted clear and unmistakable evidence that the condition existed prior to service, despite the negative entrance examination report. The RO specifically cited to the negative entrance examination in its 1959 proposed rating decision. It appears the RO evaluated and weighed the evidence and ultimately determined that the Veteran's statements were the most probative evidence of record as to when his asthma began. As noted above, a disagreement with how the RO evaluated the facts is inadequate to support a claim of CUE. Luallen, 8 Vet. App. at 95 (1995); see also 38 C.F.R. § 20.1403(d)(3). Further, there is no indication that the regulatory provisions existing at the time of the rating decision were misapplied. The Veteran's representative argues that, conceding that asthma did pre-exist active service, the RO did not consider whether it was aggravated by service, nor did the RO identify the nature of the error in the original 1948 grant of service connection in its October 1960 rating decision. However, the Board notes that the RO described the basis for its finding that the grant of service connection in 1948 was clear and unmistakable error in the December 1959 proposed severance rating decision. Moreover, it is clear from the July 1960 letter to the Veteran, wherein he was informed of the proposed severance, that the RO had considered aggravation. Specifically, the letter stated that there was no evidence showing that the Veteran's asthma was permanently aggravated during service, and cited to the post-service VA examination findings in support of that conclusion. Therefore, because the October 1960 rating decision was supported by the evidence of record as analyzed under the law in effect at the time, that rating decision, which severed service connection for asthma, was within the bounds of sound judgmental discretion. Under those circumstances, the Board finds that the October 1960 rating decision was not a product of CUE. IV. New and Material Evidence to Reopen the Claim As discussed above, service connection was originally granted for asthma, with an effective date of October 24, 1945, in a May 1948 rating decision. However, in July 1960, VA sent the Veteran notice of a proposal to sever service connection for asthma, and service connection was ultimately severed in the October 1960 rating decision. The Veteran did not file a timely appeal. Consequently, the October 1960 rating decision became final. See 38 U.S.C.A. § 7105; 38 C.F.R. § 20.302. The Veteran filed requests in February 2002 and May 2005 to reopen his case and reinstate service connection for asthma. However, the RO did not reopen his claim (for failure to provide or identify new and material evidence) in September 2002 and August 2005 rating decisions. Those decisions also became final for lack of an appeal. Most recently, in September 2005, the Veteran filed a request to reopen his claim for service connection for asthma. That request was denied in the November 2005 rating action which is the subject of the instant appeal. Based on the procedural history outlined above, the issue for consideration is whether new and material evidence has been received to reopen the claim. It appears that the RO addressed the asthma claim on the merits in its November 2005 rating decision, January 2006 SOC, and April and October 2006 SSOCs. However, the preliminary question of whether a previously denied claim should be reopened is a jurisdictional matter that must be addressed before the Board may consider the underlying claim on its merits. Barnett v. Brown, 8 Vet. App. 1, 4, (1995), aff'd, Barnett v. Brown, 83 F.3d 130 (Fed. Cir. 1996). Therefore, regardless of the manner in which the RO characterized the issue, the initial question before the Board is whether new and material evidence has been presented. Effective from August 29, 2001, "new" evidence is defined as evidence not previously submitted to agency decision-makers. "Material" evidence means existing evidence that, by itself or when considered with previous evidence of record, relates to an unestablished fact necessary to substantiate the claim. New and material evidence can be neither cumulative nor redundant of the evidence of record at the time of the last prior final denial of the claim sought to be reopened, and must raise a reasonable possibility of substantiating the claim. 38 C.F.R. § 3.156(a). When determining whether the claim should be reopened, the credibility of the newly submitted evidence is presumed. Justus v. Principi, 3 Vet. App. 510 (1992). However, lay assertions of medical causation cannot serve as the predicate to reopen a claim under section 5108. See Moray v. Brown, 5 Vet. App. 211, 214 (1993). In order for evidence to be sufficient to reopen a previously disallowed claim, it must be both new and material. If the evidence is new, but not material, the inquiry ends and the claim cannot be reopened. See Smith v. West, 12 Vet. App. 312, 314 (1999). If it is determined that new and material evidence has been submitted, the claim must be reopened. VA may then proceed to evaluate the merits of the claim on the basis of all evidence of record, but only after ensuring that the duty to assist the Veteran in developing the facts necessary for his claim has been satisfied. See Elkins v. West, 12 Vet. App. 209 (1999), but see 38 U.S.C.A. § 5103A (eliminating the previous requirement of a well-grounded claim). The evidence of record at the time of the last final rating action (August 2005) denying the Veteran's claim of entitlement to service connection for asthma included the STRs; private treatment records from Campbell Health System from June 2002; VA examinations from May 1946, May 1948, May 1953, and August 2002; letters from neighbors and relatives; and a May 2005 letter from the Veteran's family physician, Dr. A.K.G. The STRs show that the Veteran experienced an asthma attack while in active service. In addition, he reported to his treating Army physicians that he had suffered a previous episode of asthma accompanied by an upper respiratory infection in November 1941, prior to entry into active service. The VA examination reports varied in opinion as to whether the Veteran's asthma had pre- existed his entry into service. The most current (August 2002) VA examiner opined that the Veteran did not currently have, and had not ever previously had, asthma. Based upon the above evidence, the claim was denied. Specifically, the RO in August 2005 determined that there was no new and material evidence which tended to substantiate the assertion that chronic bronchial asthma was incurred in or aggravated by active service, a fact necessary to the Veteran's claim for reinstatement of service connection. Evidence added to the record since the time of the last final denial in August 2005 includes a September 2005 statement from Dr. A.K.G., a July 2006 VA examination and accompanying October 2006 addendum, and an independent medical evaluation from Dr. C.N.B. Dr. A.K.G.'s statement supports the Veteran's contention that environmental factors to which he was exposed in active service caused or at least exacerbated his asthma; and Dr. C.N.B.'s report states that the Veteran did not have asthma prior to service, that the condition began in service, and that the Veteran continues to experience recurrence of asthmatic symptoms. The evidence added to the record since the previous August 2005 denial constitutes new and material evidence. It addresses the existence of a current disability and the relationship between active service and the disability, which are unestablished facts necessary to substantiate the claim. Further, the new evidence is not redundant, as there have been no previous records containing a definitive explanation addressing the issue of causation of the Veteran's asthma. Finally, it does raise a reasonable possibility of substantiating the claim. Therefore, the Board finds that the criteria under 38 C.F.R. § 3.156(a) have been satisfied, and the claim is reopened. Because the RO considered the merits of the underlying service connection claim in the November 2005 rating action, and also in the January 2006 SOC, and April and October 2006 SSOCs that are part of the pending appeal, the Board may proceed with appellate review at this time without prejudicing the Veteran. See Bernard v. Brown, 4 Vet. App. 384, 393-94 (1993). V. Service Connection on the Merits A. Applicable Law Service connection may be granted for disability which is the result of disease or injury incurred in or aggravated by service. 38 U.S.C.A. § 1110 (West 2002 & Supp. 2010); 38 C.F.R. § 3.303(a) (2010). Where there is a chronic disease shown as such in service or within the presumptive period under 38 C.F.R. § 3.307 so as to permit a finding of service connection, subsequent manifestations of the same chronic disease at any later date, however remote, are service connected, unless clearly attributable to intercurrent causes. This rule does not mean that any manifestation in service will permit service connection. To show 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, as distinguished from merely isolated findings or a diagnosis including the word "chronic." When the disease identity is established, there is no requirement of evidentiary showing of continuity. When the fact of chronicity in service is not adequately supported, then a showing of continuity after discharge is required to support the claim. 38 C.F.R. § 3.303(b). Service connection may be granted for disease that is diagnosed after discharge, when all the evidence, including that pertinent to service, establishes that the disease was incurred in service. 38 U.S.C.A. § 1113(b); 38 C.F.R. § 3.303(d). The Court of Appeals for Veterans Claims has held that, in order to prevail on the issue of service connection, 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 present disease or injury. Hickson v. West, 12 Vet. App. 247, 253 (1999). It is the Board's responsibility to evaluate the entire record on appeal. See 38 U.S.C.A. § 7104(a). When there is an approximate balance in the evidence regarding the merits of an issue material to the determination of the matter, the benefit of the doubt in resolving each such issue shall be given to the claimant. 38 U.S.C.A. § 5107(b); 38 C.F.R. § 3.102. In Gilbert v. Derwinski, 1 Vet. App. 49, 53 (1990), the Court of Appeals for Veterans Claims held that an appellant need only demonstrate that there is an "approximate balance of positive and negative evidence" in order to prevail. The Court has also stated, "It is clear that to deny a claim on its merits, the evidence must preponderate against the claim." Alemany v. Brown, 9 Vet. App. 518, 519 (1996), citing Gilbert. B. Facts and Analysis In this case, the Veteran contends that he has a current diagnosis of asthma which was caused by his active military service in the Army. A review of the Veteran's STRs shows that his January 1942 entrance medical examination was normal, with the exception of first degree pes planus and hemorrhoids. There is no indication or notation of respiratory problems or asthma. Next, while in active service, the Veteran was hospitalized for approximately 10 days in February 1943 for acute bronchial asthma. The form entitled "Clinical Record Brief" states "No E.P.T.E. [i.e., did not exist prior to entry]" in the space to indicate whether the illness or injury was incurred in the line of duty. Further review of the records from his hospitalization reveals that he was admitted with asthmatic symptoms, and gave a history of recurrences of wheezing and shortness of breath with each cold with which he had suffered since the pre-service onset in November 1941. At that time, he had an illness characterized by fever, malaise, weakness, headaches, and cough. In addition, with this illness, he had wheezing and shortness of breath, and was told that he had asthma. A Progress Note dated February 15, 1943, reported that the patient had been completely asymptomatic since admission. A February 18, 1943, Progress Note stated that the history pointed to a mild asthma presumably secondary to bacterial antigen and that, because such an individual is very apt to develop sensitivity to other antigens, and considering the discomfort of wearing a gas mask, his job responsibility should be reclassified. In a Final Summary entry dated February 20, 1943, the treatment provider wrote that the Veteran's history suggested bronchial asthma, presumably due to sensitization to bacterial antigens. There were no further recorded incidents of asthma while the Veteran was in service. His October 1945 separation examination report has a notation of the hospitalization for asthma in February 1943, but is otherwise normal. Under the "Lungs" category, the report states that they were normal, but also states, "Asthma, LD (Line of Duty), no E.P.T.S.," indicating that the condition was incurred during active service and not prior to service. Following service, the Veteran filed a claim for entitlement to service connection for asthma in December 1945. Then, he was afforded several VA examinations shortly after separation from service. First, after a normal physical examination, the May 1946 VA examiner diagnosed asthma by history only, with attacks occurring every three months on average. Next, during a May 1948 VA examination, there was equal and full expansion of the lungs, which were normal to percussion. On auscultation, there was an accentuation of the expiratory phase with occasional high-pitched bronchiolar rale. The examiner diagnosed mild bronchial asthma. There is also notation in the report that this condition had existed prior to service, first appearing in 1941 (consistent with the history the Veteran provided in the STRs). Physical examination results were similar during a May 1953 VA examination. Expansion was equal, tactile fremitus and percussion were normal, and breath sounds were broncho-vesicular with no sonorous or sibilant rales, and no post-tussive rales. The diagnosis was chronic bronchial asthma from history and records. The next indication of respiratory problems is contained in June 2002 records from the Campbell Health System. Thus, there is no documentation showing treatment for asthmatic or respiratory symptoms until almost 57 years after separation from service. In this regard, the Board notes that evidence of a prolonged period without medical complaint or treatment and the amount of time which has elapsed since military service can be considered, along with other factors, as evidence against the claim. Maxson v. Gober, 230 F.3d 1330, 1333 (Fed. Cir. 2000). The Campbell Health System records show that the Veteran underwent a pulmonary function study which was found to be abnormal. Specifically, the report indicates mild vital capacity deficit, minimal volume and flow improvement after bronchodilator at present, mild-to-moderate air trapping, moderate total lung capacity deficit, moderate reduction in diffusing capacity, and flow volume loops that indicated moderate restrictive defect. These findings were consistent with a restrictive ventilator defect suggestive of interstitial lung disease, pulmonary vascular, or occlusive disease. The report stated that some of the vital capacity deficit might be due to cardiac enlargement, interstitial pulmonary fibrosis, chest wall disease, previous lung tissue resection, etc. There is no diagnosis of asthma contained in those records. Two months later, the Veteran was afforded a VA examination, in August 2002. The examiner had access to the claims file. At that examination, the Veteran told the examiner he had no previous history of having had respiratory disease or asthma prior to entering the service. He stated he had been treated one month before the examination for asthma, which had followed on the heels of a bronchial infection. This was the first time he had received any treatment for a respiratory problem in 20 years. Pulmonary function tests showed minimal restrictive ventilatory defect, and were not consistent with any current or prior asthmatic component. According to the examiner, the Veteran's history showed that he had suffered an episode of bronchitis while in the service with a transitory asthmatic affect that was readily contained on medication. The examiner opined that the condition had not been permanently worsened by service. The current examination, however, did show crackling rales in the right lower lung field, posteriorly. Chest X-rays showed eventration of the left hemidiaphragm but was otherwise normal. The lungs were clear. Next, the claims file contains a May 2005 letter from the Veteran's family physician, Dr. A.K.G. The doctor stated that the Veteran has current diagnoses of restricted lung disease and mild intermittent asthma, and that prior to October 1942 he had had no respiratory problems. Further, his first episode of asthma had occurred while he was in the military. The doctor noted the Veteran worked in a dusty environment as an aircraft repairman, and quit smoking in 1957. Finally, according to the doctor, while the Veteran's respiratory status does not require oxygen, it does make him more susceptible to infectious processes. The file also contains letters from the Veteran's sister and neighbor. The letter from his sister, dated in July 2005, states that the Veteran did not have asthma prior to his enlistment in the Army. Further, she asserts that asthma symptoms surely would have shown up had the condition pre-existed service, as the Veteran worked outdoors with livestock. The July 2005 letter from the Veteran's neighbor, C.A.W., echoes the same opinion and assertion that the Veteran did not have asthma prior to service. Next, Dr. A.K.G. wrote another letter dated in September 2005, wherein she asserted that the Veteran developed asthma and restrictive lung disease due to environmental factors to which he was subjected in the military. The doctor said she based this opinion on the history of the Veteran's pulmonary symptoms and medical records. In July 2006, the Veteran was afforded another VA examination. He reported he had experienced a recurrent cough over the years since his first asthma attack. He said he had smoked about 10 cigarettes a day for 10 to 12 years, but quit smoking 50 years ago. Pulmonary function tests were performed and showed an obstructive pattern with no impairment, which could be seen as normal. Concomitant restriction or air trapping could not be ruled out. Chest X-rays were taken and compared to X-rays from August 2005. There was no significant interval change. There was persistent elevation of the left diaphragm with no change and a calcified granuloma in the left lower lung; the lungs were clear of parenchymal infiltrate, and the heart was not enlarged. The examiner, after reviewing the claims file and performing a physical examination including the above tests, diagnosed mild and persistent asthma, by history and medical documents from 1942. Further, the examiner found no evidence that the Veteran had a history of asthma prior to entry into active service. The examiner stated it would be speculation to say whether any environmental exposure in the military led to the Veteran's asthma. The July 2006 VA examiner authored an addendum opinion dated in October 2006 after reviewing sections of the claims file tabbed by the RO. The examiner stated the medical documents in the claims file provided evidence that the Veteran experienced asthmatic symptoms prior to entering service. Further, the examiner stated there was no evidence that the Veteran's asthma was permanently aggravated by military service. She based this opinion on the history provided by the Veteran that his last asthma attack had been in 1946, that he did not currently use an inhaler, that he had had some recent hospitalizations for pneumonia which did require the use of oxygen, and that he had a smoking history and obstructive sleep apnea. Finally, there is a December 2008 report by Dr. C.N.B., a private physician retained by the Veteran for an independent medical evaluation. Dr. C.N.B. reviewed the Veteran's claims file but did not physically examine him or take additional history from the Veteran. The doctor opines that the Veteran did not have asthma prior to entering service. He bases this opinion on the physical findings at the Veteran's 1942 entrance examination; namely, the chest measurements on inspiration and expiration, the pulse measurement taken after exercise, and the lack of any notation that the Veteran had difficulty breathing in the examination report. Further, he discredits the report by the Veteran in the STRs that he had an asthma attack in 1941, prior to entering service, as the Veteran is a layperson not qualified to make such diagnoses. Next, Dr. C.N.B. supports the contention that the Veteran has a current diagnosis of asthma that has been longstanding since active service. The doctor challenges the opinion of the August 2002 VA examiner that the Veteran does not have a current diagnosis of asthma. Specifically, Dr. C.N.B. states that the August 2002 pulmonary function test, particularly the albuterol test, was done incorrectly, as the Veteran had the same FEV and FVC prior to and after bronchial dilator therapy, which he says is impossible. An additional criticism was that the 2002 VA examiner's statement that there was no significant obstructive defect is not the same as no obstructive defect, and thus, the change in diagnosis from asthma to no asthma is not well supported. Moreover, the chest films from 2005 and 2006 show an elevated left diaphragm which is consistent with pulmonary scarring, as would be expected in longstanding asthma with recurrent infections. Finally, the 2002 VA examiner did not incorporate the Veteran's history of being exposed to airplane dust while in service, and the 2006 VA examiner did not account for the results of the sputum test conducted in May 1953, which had 6 eosinophils and is consistent with asthma. The Board has first considered whether the Veteran has a current diagnosis of asthma, and concludes that the preponderance of the evidence shows that he does not currently have asthma. In reaching this conclusion, the Board has weighed a number of medical opinions. In cases such as this, where there are conflicting statements or opinions from medical professionals, it is within the Board's province to weigh the probative value of those opinions. In Guerrieri v. Brown, 4 Vet. App. 467, 470-71 (1993), the Court of Veterans Appeals stated: The probative value of medical opinion evidence is based on the medical expert's personal examination of the patient, the physician's knowledge and skill in analyzing the data, and the medical conclusion that the physician reaches. . . . As is true with any piece of evidence, the credibility and weight to be attached to these opinions [are] within the province of the adjudicators . . . . So long as it provides an adequate reason or basis for doing so, the Board does not err by favoring one competent medical opinion over another. See Owens v. Brown, 7 Vet. App. 429, 433 (1995). Greater weight may be placed on one examiner's opinion over another depending on factors such as reasoning employed by the examiners and whether or not, and the extent to which they reviewed prior clinical records and other evidence. Gabrielson v. Brown, 7 Vet. App. 36, 40 (1994). In addition, the thoroughness and detail of a medical opinion are among the factors for assessing the probative value of the opinion. See Prejean v. West, 13 Vet. App. 444, 448-9 (2000). First, the Board acknowledges that the October 1945 separation examination report, as well as the VA examinations from May 1946, May 1948, and May 1953, all appear to support a diagnosis of asthma at that time. However, in determining whether the Veteran has a current diagnosis of asthma, the Board will focus on more recent medical documentation. In support of a current diagnosis of asthma are the opinions of Drs. A.K.G. and C.N.B. By contrast, the August 2002 VA examiner concluded that the Veteran's history and present physical examination were not consistent with a diagnosis of asthma. The Board finds that the opinions of Drs. A.K.G. and C.N.B. are less probative than that of the 2002 VA examiner, for the following reasons. Dr. A.K.G.'s May 2005 letter stated that the Veteran has a current diagnosis of mild intermittent asthma. However, she provides no basis for this diagnosis, such as test results or physical examination findings, nor are there any other records from that doctor which contain such results or findings. In fact, a pulmonary function study from June 2002 from the Campbell Health System, with Dr. A.K.G.'s name at the bottom, indicates no finding of asthma. Thus, Dr. A.K.G.'s opinion is conclusory and appears to be speculative at best. Speculative medical opinions are insufficient to establish service connection. See Stegman v. Derwinski, 3 Vet. App. 228, 230 (1992); Tirpak v. Derwinski, 2 Vet. App. 609, 611 (1992). Next, Dr. C.N.B. concluded that the Veteran has a current diagnosis of asthma on the basis of a review of medical records, without having seen or examined the Veteran. The doctor seems to base this opinion somewhat on the physical examination findings from the 1942 service separation examination as well as the VA examinations from 1946, 1948, and 1953 that followed shortly thereafter. As stated above, the Board does not find these documents to be probative on the question of whether the Veteran has a current diagnosis of asthma. Further, Dr. C.N.B. bases his opinion in part on discrediting the opinion of the 2002 VA examiner. First, he concludes that the pulmonary function test must have been administered incorrectly. However, this is a conclusory statement with no basis other than that the doctor disagrees with the results of the test. It is speculative, and thus cannot be relied upon to form the basis of an opinion regarding whether a current diagnosis exists. See Stegman, 3 Vet. App. at 230 (1992); Tirpak, 2 Vet. App. at 611 (1992). As stated above, Dr. C.N.B. further asserts that the 2002 VA examiner did not take the films showing an elevated left diaphragm into account. However, upon reviewing the 2002 VA examination report, the Board notes that the results of chest X- rays taken in August 2002 which show irregularity of the left hemidiaphragm are attached to the examination report, which would indicate that it was a factor in the examiner's conclusion. By contrast, the August 2002 VA examiner conducted a physical examination of the Veteran, including a pulmonary function test and chest X-rays, and reviewed the claims file, as stated in the report and made apparent by mention of some highlights of the Veteran's medical history. The examiner also took a verbal history from the Veteran. Notably, as previously stated, the Veteran told the examiner he had not been treated for a respiratory problem in 20 years, which buttresses the examiner's opinion that the Veteran does not currently have asthma. The 2002 VA examiner also provided specific narrative support for his opinion. With regard to the 2006 VA examiner's diagnosis of asthma by history, thorough review of the report shows that the diagnosis was made on the basis of medical documentation from 1942 and the Veteran's verbal history rather than on any current testing or physical examination. For example, the examiner stated the pulmonary function test performed as part of the examination could be read as normal. Thus, the examiner made a diagnosis based on history and not current physical symptoms or testing, and the Board does not consider that diagnosis to be probative in determining whether there is a current asthma disorder. For these reasons, Drs. A.K.G. and C.N.B's and the 2006 VA examiner's opinions are found to be less probative than the opinion of the August 2002 VA examiner regarding whether a current diagnosis of asthma exists. Accordingly, the greater weight of the probative evidence is against finding that the Veteran has a current diagnosis of asthma. As a result, the claim must fail. Indeed, in the absence of proof of a present disability there can be no valid claim. Brammer v. Derwinski, 3 Vet. App. 223, 225 (1992). The Board recognizes that the Court has held that the presence of a chronic disability at any time during the claim process can justify a grant of service connection, even where the most recent diagnosis is negative. McClain v. Nicholson, 21 Vet. App. 319 (2007). However, where the overall record (which here includes exhaustive medical evidence as well as history) fails to support a current diagnosis of the claimed disability, that holding is inapplicable. The Board acknowledges that the Veteran is competent to give evidence about what he experienced; for example, he is competent to discuss his current shortness of breath and other experienced symptoms. See, e.g., Layno v. Brown, 6 Vet. App. 465 (1994). Moreover, the Federal Circuit Court has held that in certain situations, lay evidence can even be sufficient with respect to establishing medical matters such as a diagnosis. Specifically, in Jandreau v. Nicholson, 492 F.3d 1372 (Fed. Cir. 2007), the Federal Circuit commented that competence to establish a diagnosis of a condition can exist when (1) a layperson is competent to identify the medical condition, (2) the layperson is reporting a contemporaneous medical diagnosis, or (3) lay testimony describing symptoms at the time supports a later diagnosis by a medical professional. See also Davidson v. Shinseki, 581 F.3d 1313 (2009) (noting that a layperson may comment on lay-observable symptoms). Similarly, the Court of Appeals for Veterans Claims has held that, when a condition may be diagnosed by its unique and readily identifiable features, the presence of the disorder is not a determination "medical in nature" and is capable of lay observation. Barr v. Nicholson, 21 Vet. App. 303 (2007). Furthermore, lay evidence concerning continuity of symptoms after service, if credible, is ultimately competent, regardless of the lack of contemporaneous medical evidence. Buchanan v. Nicholson, 451 F.3d 1331 (Fed. Cir. 2006). However, the resolution of issues which involve medical knowledge, such as the diagnosis of a disability and the determination of medical etiology, requires professional evidence. See Espiritu v. Derwinski, 2 Vet. App. 492, 495 (1992). In the present case, the Veteran asserts that he has asthma that is related to service. Specifically, he asserts that his first attack occurred in service and that he has had recurrent symptoms since that time. Even if his statements can be construed as alleging continuity of symptoms since active service, the absence of documented complaints or treatment for 47 years following military discharge is more probative than his current recollection as to symptoms experienced in the distant past. See Curry v. Brown, 7 Vet. App. 59 (1994). Further, the Veteran stated during the August 2002 VA examination that he had not had respiratory problems in the past 20 years. Therefore, continuity has not here been established, either through the competent medical evidence or through the Veteran's statements. The Board recognizes the sincerity of the Veteran's belief that he has a disability at this time which was caused by active service. However, the resolution of issues which involve medical knowledge, such as the diagnosis of a disability and the determination of medical etiology, require professional evidence. See Espiritu v. Derwinski, supra. The Veteran's lay statements may be competent to support a claim for service connection by supporting the occurrence of lay-observable events or the presence of disability or symptoms of disability subject to lay observation, as discussed above. However, in this case, the weight of the evidence is against a finding that the Veteran has the claimed disability. The physical testing and examinations performed do not show evidence of asthma, and the Veteran himself has stated that there was a period of 20 years during which he experienced no respiratory problems. Thus, the weight of the competent evidence is against a grant of service connection for asthma. Because the preponderance of the evidence is against the claim, there is no reasonable doubt to resolve in the Veteran's favor and the claim must be denied. See 38 U.S.C.A. § 5107(b); 38 C.F.R. § 3.102; Gilbert, supra. The Board appreciates the vigorous advocacy by the Veteran's representative in this case. ORDER The Board's decision of January 15, 2009, is hereby vacated. Clear and unmistakable error was not committed by the RO in the October 1960 rating decision which severed service connection for asthma, and the appeal as to CUE is denied. The reopened claim for service connection for asthma is denied. ___________________________ ANDREW J. MULLEN Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
