Citation Nr: 1328282 Decision Date: 09/05/13 Archive Date: 09/16/13 DOCKET NO. 09-46 749A ) DATE ) ) On appeal from the Department of Veterans Affairs Regional Office in Oakland, California THE ISSUES 1. Whether there is new and material evidence to reopen a claim of entitlement to service connection for hearing loss. 2. Entitlement to service connection for left ear hearing loss. 3. Whether there is new and material evidence to reopen a claim of entitlement to service connection for tinnitus. 4. Entitlement to a rating higher than 50 percent for posttraumatic stress disorder (PTSD), other than during times when the Veteran had a temporary 100 percent rating for this disability under the provisions of 38 C.F.R. § 4.29 because of hospital treatment exceeding 21 days. 5. Entitlement to a total disability rating based on individual unemployability (TDIU). REPRESENTATION Veteran represented by: C. Kempton Letts, Esq. WITNESSES AT HEARING ON APPEAL The Veteran and his spouse ATTORNEY FOR THE BOARD C. Kedem, Counsel INTRODUCTION The Veteran served on active duty from March 1968 to January 1970. This appeal to the Board of Veterans' Appeals (Board/BVA) is from a January 2009 rating decision in which the Department of Veterans Affairs (VA) Regional Office (RO) declined to reopen the Veteran's claims of entitlement to service connection for bilateral (right and left ear) hearing loss and tinnitus, denied entitlement to a TDIU, and other than permitting a temporary total (100 percent) evaluation for his service-connected PTSD because of a hospitalization exceeding 21 days, denied an evaluation higher than 50 percent for this disability. In November 2012, in support of these claims, the Veteran testified at a hearing at the RO before the undersigned Veterans Law Judge of the Board (Travel Board hearing). A transcript of the hearing is of record. During the hearing the Veteran submitted additional evidence and waived his right to have the RO initially consider it, preferring instead to have the Board do so in the first instance. 38 C.F.R. § 20.1304(c) (2012). The issues of whether there is new and material evidence to reopen the claim for service connection for tinnitus and entitlement to a TDIU require further development, so the Board is remanding these claims. FINDINGS OF FACT 1. A March 2004 rating decision denying service connection for bilateral hearing loss is a final and binding determination based on the evidence then of record; although relevant evidence was added to the record within a year of that decision, the RO considered that additional evidence and all other evidence then of evidence in a subsequent statement of the case (SOC), and in response the Veteran failed to submit a timely substantive appeal (VA Form 9 or equivalent statement) to complete the steps necessary to perfect his appeal of this claim to the Board. 2. But regarding his left ear, additional evidence received since that March 2004 rating decision is not cumulative and redundant and raises a reasonable possibility of substantiating his claim of entitlement to service connection for hearing loss, at least in this particular ear. 3. Regarding his right ear, however, the additional evidence received since the March 2004 rating decision is cumulative and redundant and does not raise a reasonable possibility of substantiating his claim of entitlement to service connection for hearing loss in this other ear. 4. His left ear hearing loss did not originate during his military service, or within one year of his discharge, or even for many ensuing years, and it is unrelated to his service, including especially to any noise exposure he experienced in service and consequent injury (acoustic trauma). 5. His service-connected PTSD causes occupational and social impairment with deficiencies in most areas such as work, school, family relations, judgment, thinking, or mood. CONCLUSIONS OF LAW 1. The unappealed March 2004 rating decision that denied the Veteran's claim of entitlement to service connection for bilateral (left and right ear) hearing loss is final and binding based on the evidence then of record. 38 U.S.C.A. § 7105 (West 2002); 38 C.F.R. §§ 3.104(a), 3.160(d), 20.200, 20.1103 (2012). 2. But there is new and material evidence since that decision to reopen the claim for service connection for hearing loss in the left ear, though not also as concerning the alleged hearing loss in the right ear. 38 U.S.C.A. § 5108 (West 2002); 38 C.F.R. § 3.156(a) (2012). 3. It still is not shown, however, the left ear hearing loss is the result of disease or injury incurred in or aggravated by his military service or that it may be presumed to have been incurred during his service. 38 U.S.C.A. §§ 1101, 1110, 1112, 1113, 5103, 5103A, 5107 (West 2002); 38 C.F.R. §§ 3.102, 3.159, 3.303, 3.307, 3.309, 3.385 (2012). 4. The criteria are met for a higher 70 percent rating for the PTSD, though no greater rating. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 4.1, 4.2, 4.3, 4.7, 4.10, 4.21, 4.125, 4.130, Diagnostic Code 9411 (2012). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS Veterans Claims Assistance Act of 2000 (VCAA) As provided by the VCAA, VA has duties to notify and assist claimants in substantiating claims for VA benefits. 38 U.S.C.A. §§ 5100, 5102, 5103, 5103A, 5107, 5126 (West 2002 & Supp. 2012); 38 C.F.R. §§ 3.102, 3.156(a), 3.159 and 3.326(a) (2012). Upon receipt of a complete or substantially complete application for benefits, VA is required to notify the claimant and his or her representative, if any, of any information, and any medical or lay evidence, which 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). To this end, 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 obtain; and (3) that the claimant is expected to provide. Ideally, this notice should be provided prior to an initial unfavorable decision on a claim by the RO as the Agency of Original Jurisdiction (AOJ). Mayfield v. Nicholson, 444 F.3d 1328 (Fed. Cir. 2006); Pelegrini v. Principi, 18 Vet. App. 112 (2004). If, however, for whatever reason it was not, or the notice provided was inadequate or incomplete, the issuance of a fully compliant VCAA notification followed by readjudication of the claim, including in a statement of the case (SOC) or supplemental SOC (SSOC), is sufficient to "cure" the timing defect in the provision of this notice. See Mayfield v. Nicholson, 499 F.3d 1317, 1323 (Fed. Cir. 2007) (Mayfield IV); Prickett v. Nicholson, 20 Vet. App. 370 (2006). In Dingess v. Nicholson, 19 Vet. App. 473 (2006), the U. S. Court of Appeals for Veterans Claims (Court/CAVC) held that, upon receipt of an application alleging entitlement to service connection, 38 U.S.C. § 5103(a) and 38 C.F.R. § 3.159(b) require VA to review the information and evidence presented with the claim and provide the claimant 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. So this consist of notice of both what is required to establish underlying entitlement to service connection (i.e., (1) Veteran status, (2) proof the Veteran has the alleged disability, and (3) a relationship between the disability and his military service), but also as concerning a "downstream" (4) disability rating and (5) effective date for the award of benefits in the eventuality service connection is granted. In Kent v. Nicholson, 20 Vet. App. 1 (2006), the Court clarified VA's duty to notify in the context of petitions to reopen previously denied claims. With respect to such claims, VA must both notify a claimant of the evidence and information that is necessary to reopen the claim and of the evidence and information necessary to establish entitlement to the underlying claim for the benefit that is being sought. To satisfy this requirement, VA is required to look at the bases for the denial in the prior decision and provide the claimant a notice letter describing what evidence would be necessary to substantiate those elements required to establish entitlement to service connection that were found insufficient in the previous denial. VA's Office of General Counsel issued informal guidance interpreting Kent as requiring the notice to specifically identify the kind of evidence that would overcome the prior deficiency rather than simply stating the evidence must relate to the stated basis of the prior denial. See VA Gen. Couns. Mem., para. 2, 3 (June 14, 2006). But a VCAA notice error is not presumptively prejudicial, even when shown to have occurred, rather, must be judged on a case-by-case basis. And as the pleading party attacking the agency's decision, the Veteran, not VA, bears this evidentiary burden of proof of not only establishing error, but, above and beyond that, showing how it is unduly prejudicial, meaning outcome determinative of his claim. Shinseki v. Sanders, 129 S. Ct. 1696 (2009). Here, the VCAA duty to notify was satisfied by way of a letter sent to the Veteran in June 2008 that fully addressed all three notice elements. The letter informed him of the evidence required to substantiate his claims and of his and VA's respective duties in obtaining this necessary supporting evidence. He also was apprised of the applicable provisions regarding disability ratings and effective dates. As well, he was advised of the reasons his service- connection claims were previously denied and informed of the type of evidence needed to reopen these finally-decided claims. VA also as mentioned has a duty to assist the Veteran in the development of his claims. This duty includes assisting him in the procurement of relevant records such as his service treatment records (STRs), post-service VA and private medical records, records from other Federal agencies such as the Social Security Administration (SSA), and providing him an examination for a medical opinion when necessary to decide his claim. 38 U.S.C.A. § 5103A; 38 C.F.R. § 3.159(c). The Board finds that all necessary development has been accomplished, and therefore appellate review may proceed without prejudicing him, at least as concerning the claims being decided. See Bernard v. Brown, 4 Vet. App. 384 (1993). The record contains his STRs, VA clinical records, private medical records, and VA examination reports. Regarding examination, when VA undertakes to provide a medical examination, it must ensure the examination is adequate. Barr v. Nicholson, 21 Vet. App. 303, 312 (2007). As to these claims being decided, the examinations provided and opinions obtained are adequate, as they were based on a review of the pertinent evidence of record, clinical evaluations, as well as comprehensive interviews of the Veteran, and the examination reports contain explanatory rationales for the opinions rendered. Accordingly, the Board finds that VA's duty to assist in obtaining VA examinations and opinions concerning these claims has been met. 38 C.F.R. § 3.159(c)(4). Significantly, neither the Veteran nor his representative has identified, and the record does not otherwise indicate, any additional existing evidence that is necessary for a fair adjudication of these claims that has not been obtained. Hence, no further notice or assistance to the Veteran is required to fulfill VA's duty to assist him in the development of these claims. Smith v. Gober, 14 Vet. App. 227 (2000), aff'd 281 F.3d 1384 (Fed. Cir. 2002); Dela Cruz v. Principi, 15 Vet. App. 143 (2001); see also Quartuccio v. Principi, 16 Vet. App. 183 (2002). Standard of Review After the evidence has been assembled, it is the Board's responsibility to evaluate the entire record. 38 U.S.C.A. § 7104(a) (West 2002). When there is an approximate balance of evidence regarding the merits of an issue material to the determination of a matter, the benefit of the doubt in resolving each such issue shall be given to the claimant. 38 U.S.C.A. § 5107; 38 C.F.R. §§ 3.102, 4.3 (2012) (reasonable doubt to be resolved in Veteran's favor). In Gilbert v. Derwinski, 1 Vet. App. 49, 53 (1990), the Court stated that "a Veteran need only demonstrate that there is an 'approximate balance of positive and negative evidence' in order to prevail." To deny a claim on its merits, the preponderance of the evidence must be against the claim. See Alemany v. Brown, 9 Vet. App. 518, 519 (1996), citing Gilbert, 1 Vet. App. at 54. New and Material Evidence Service connection will be granted if it is shown the Veteran suffers from disability resulting from an injury sustained or a disease contracted in the line of duty during active military service, or for aggravation during service of a pre-existing condition beyond its natural progression. 38 U.S.C.A. § 1110; 38 C.F.R. § 3.303(a). That an injury occurred in service alone is not enough; there must be chronic (i.e., permanent) disability resulting from that injury. If there is no showing of a resulting chronic condition during service, or this is legitimately questionable, then a showing of continuity of symptomatology after service is required to support a finding of chronicity and the claim. 38 C.F.R. § 3.303(b). The U. S. Court of Appeals for the Federal Circuit (Federal Circuit Court) has clarified, however, that this notion of continuity of symptomatology as an alternative means of showing chronicity of disease or injury in service to alternatively link the currently claimed disability to service only pertains to chronic diseases listed in 38 C.F.R. § 3.309(a). See Walker v. Shinseki, 708 F.3d 1331 (Fed. Cir. 2013). Although Walker indicated that hearing loss in general is not one of the conditions identified by § 3.309(a) and chronic, per se, so generally not subject to this continuity of symptomatology pleading and proof exception, VA accepts that a particular type of hearing loss - namely, sensorineural hearing loss - is covered by this VA regulation as an organic disease of the nervous system. The Veterans Benefits Administration's (VBA's) M21-1MR has a section titled "Determining Impaired Hearing as a Disability," which includes the following note: "Sensorineural hearing loss is considered an organic disease of the nervous system and is subject to presumptive service connection under 38 CFR 3.309(a)." M21-1MR III.iv.4.B.12.a. The VA Manual has the force and effect of a VA regulation. Furthermore, as an organic disease of the nervous system, sensorineural hearing loss also may be presumed to have been incurred in service if manifested to a compensable degree (meaning to at least 10-percent disabling) within one year of separation from service. This presumption is rebuttable by affirmative evidence to the contrary, however. 38 U.S.C.A. §§ 1101, 1112, 1113; 38 C.F.R. §§ 3.307, 3.309(a). So service connection may be established either by showing direct service incurrence or aggravation or by using applicable presumptions, if available. See Combee v. Brown, 34 F.3d 1039, 1043 (Fed. Cir. 1994). Service connection is permissible for any disease diagnosed after discharge, when the evidence, including that pertinent to service, establishes the disease was incurred in service. 38 C.F.R. § 3.303(d). In sum, to establish entitlement to service connection, the following must be shown: (1) the existence of a present disability; (2) in-service incurrence or aggravation of a relevant disease or an 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, 1167 (Fed. Cir. 2004). As specifically concerning claims of entitlement to service connection for hearing loss, the threshold for normal hearing is from zero to 20 decibels, and higher threshold levels indicate some degree of hearing loss. Hensley v. Brown, 5 Vet. App. 155, 157 (1993) (citing Current Medical Diagnosis & Treatment, Stephen A. Schroeder, et. al. eds., at 110-11 (1988)). According to VA standards, however, impaired hearing only will be considered to be an actual ratable disability when the auditory threshold in any of the frequencies 500, 1000, 2000, 3000, or 4000 Hertz is 40 decibels or greater; or when the auditory thresholds for at least three of these frequencies are 26 decibels or greater; or when speech recognition scores using the Maryland CNC Test are less than 94 percent. 38 C.F.R. § 3.385. But for service connection, it is not required that a hearing loss disability by these standards of 38 C.F.R. § 3.385 be demonstrated during service, or even within the one-year presumptive period following discharge, although a hearing loss disability by these standards of § 3.385 must be currently present to have a ratable disability. If there is current ratable hearing loss disability, then service connection is possible if this current disability can be adequately linked to the Veteran's military service as opposed to other unrelated factors. Ledford v. Derwinski, 3 Vet. App. 87, 89 (1992). Service connection for hearing loss may be granted where there is competent and credible evidence of acoustic trauma due to significant noise exposure in service, post-service audiometric findings meeting regulatory requirements for hearing loss disability for VA purposes (i.e., 38 C.F.R. § 3.385 ), and a medically sound basis upon which to attribute the post-service findings to the injury in service, as opposed to intercurrent causes. Hensley, 5 Vet. App. at 159. A claim of entitlement to service connection generally must be accompanied by medical evidence establishing the claimant currently has the claimed disability or, at the very least, showing he has at some point since the filing of his claim. Absent proof of present disability, there can be no valid claim. See, e.g., Gilpin v. West, 155 F.3d 1353 (Fed. Cir. 1998) (38 U.S.C. § 1110 requires current symptomatology at the time the claim is filed in order for a Veteran to be entitled to compensation); Degmetich v. Brown, 104 F.3d 1328 (Fed. Cir. 1997) (38 U.S.C. § 1131 requires the existence of a present disability for VA compensation purposes); Brammer v. Derwinski, 3 Vet. App. 233, 225 (1992) (noting that service connection presupposes a current diagnosis of the claimed disability); Chelte v. Brown, 10 Vet. App. 268 (1997) (observing that a "current disability" means a disability shown by competent medical evidence to exist at the time of the award of service connection). There are instances when the type of disability claimed is what is considered a simple condition, allowing for lay evidence to establish its existence. So medical evidence is not always or categorically required when the determinative issue involves either medical diagnosis or etiology, but rather such issue may, depending on the facts of the particular case, be established by competent and credible lay evidence under 38 U.S.C.A. § 1154(a). See Davidson v. Shinseki, 581 F.3d 1313 (Fed. Cir. 2009). But that said, although claimants may be competent to provide the diagnoses of simple conditions, such as a broken leg, separated shoulder, pes planus (flat feet), varicose veins, tinnitus (ringing in the ears), etc., they are not competent to provide evidence on more complex medical questions beyond simple observations, such as concerning cancer. See Jandreau v. Nicholson, 492 F.3d 1372, 1377 (Fed. Cir. 2007) (indicating lay evidence can be competent and sufficient to establish a diagnosis of a condition 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 Colantonio v. Shinseki, 606 F.3d 1378, 1382 (Fed. Cir. 2010) (recognizing that in some cases lay testimony "falls short" in proving an issue that requires expert medical knowledge); Waters v. Shinseki, 601 F.3d 1274, 1278 (Fed. Cir. 2010) (concluding that a Veteran's lay belief that his schizophrenia had aggravated his diabetes and hypertension was not of sufficient weight to trigger VA's duty to seek a medical opinion on the issue). Turning now to the relevant facts and procedural history of this case. In a March 2004 rating decision the RO denied the Veteran's claim of entitlement to service connection for bilateral hearing loss because he did not have sufficient hearing loss to be considered a ratable disability according to VA regulation. See 38 C.F.R. § 3.385. He was properly notified of that March 2004 rating decision, but although he initiated an appeal, he did not perfect it. In other words, he filed a timely notice of disagreement (NOD), resultantly was provided an SOC, but did not then in response also file a timely substantive appeal (VA Form 9 or equivalent statement) to complete the steps necessary to perfect his appeal to the Board. See 38 C.F.R. § 20.200. Thus, that March 2004 rating decision is final and binding on him based on the evidence then of record. 38 C.F.R. §§ 3.104(a), 3.160(d), 20.302, 20.1103 (2012). The Board sees that a December 2004 audiogram report was added to the record within a year of that March 2004 rating decision. The report showed left ear hearing loss, so is relevant, but the RO considered this additional evidence in a February 2005 SOC. Hence, it was then incumbent on the Veteran to perfect a timely appeal upon receipt of that SOC by also filing a timely VA Form 9 or equivalent statement, but he clearly did not, so mere receipt of that additional audiogram report during the one-year he had for timely appealing that March 2004 rating decision does not vitiate the finality (res judicata) of that decision. See 38 C.F.R. § 3.156(b). Generally, when a claim is disallowed, it may not be reopened and allowed, and a claim based on the same factual basis may not be considered. 38 C.F.R. § 20.1103. A claim on which there is a final decision may be reopened if new and material evidence is submitted. 38 U.S.C.A. § 5108. "New" evidence means existing 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). The threshold for determining whether new and material evidence raises a reasonable possibility of substantiating a claim is "low." See Shade v. Shinseki, 24 Vet. App. 110, 117 (2010). Furthermore, in determining whether this low threshold is met, VA should not limit its consideration to whether the newly submitted evidence relates specifically to the reason why the claim was last denied, but instead should ask whether the evidence could reasonably substantiate the claim were the claim to be reopened, either by triggering the VA Secretary's duty to assist or through consideration of an alternative theory of entitlement. Id., at 118. Moreover, the Veteran need not present evidence as to each element that was a specified basis for the last disallowance, but merely new and material evidence as to at least one of the bases of the prior disallowance. Id., at 120 (noting that the assistance of 38 C.F.R. § 3.159(c)(4) would be rendered meaningless if new and material evidence required a claimant to submit medical nexus evidence when he has provided new and material evidence as to another missing element). The evidence submitted to reopen a claim is presumed to be true for the limited purpose of determining whether it is new and material to the claim, but VA does not have to consider the inherently incredible to be credible or to blindly accept, as true, assertions that are beyond the competence of the person making them. Duran v. Brown, 7 Vet. App. 216, 220 (1994); Justus v. Principi, 3 Vet. App. 510, 513 (1992). The evidence of record at the time of the March 2004 rating decision and that submitted within a year of it included the STRs showing a shift in thresholds but no material hearing loss and a VA audiologic examination report dated in January 2004 indicating the following results: HERTZ 500 1000 2000 3000 4000 RIGHT 5 15 15 15 20 LEFT 10 15 15 10 20 Speech recognition was 94 percent bilaterally, so in each ear. The results of a subsequent December 2004 audiogram, so later that same year, were as follows: HERTZ 500 1000 2000 3000 4000 RIGHT 15 20 20 25 25 LEFT 15 20 20 30 35 Speech recognition was 96 percent in the right ear and 92 percent in the left ear. Thus, as those results indicate, the Veteran did not have sufficient hearing loss in his right ear to be considered an actual ratable disability according to § 3.385, much less as a result or consequence of his military service. He did however have sufficient hearing loss in his left ear when considering his speech recognition score during the December 2004 evaluation (since it was less than 94 percent). The determinative question then became whether the hearing loss in his left ear was the result of his military service. See Watson v. Brown, 4 Vet. App. 309, 314 (1993) ("A determination of service connection requires a finding of the existence of a current disability and a determination of a relationship between that disability and an injury or a disease incurred in service."). The accompanying report indicated that military noise exposure could not be ruled out as a causative factor of his hearing loss. The RO considered this evidence in the February 2005 SOC but ultimately determined the left ear hearing loss was unrelated to the Veteran's military service, including to the perforated eardrums he had had in service, since no evidence then of record related (at least definitively enough) his slight left ear hearing loss to his service that had ended more than three decades earlier. The additional evidence since received includes the report of a more recent April 2008 audiologic examination with the following results: HERTZ 500 1000 2000 3000 4000 RIGHT 15 25 25 25 35 LEFT 20 20 30 30 40 Speech discrimination was 96 percent in the right ear and 92 percent in the left ear. But aside from reaffirming the Veteran had sufficient hearing loss in his left ear to be considered a ratable disability according to § 3.385, this additional examiner indicated that the type and degree of noise exposure the Veteran had experienced in service was sufficient to have caused the type of hearing loss he now has. Ultimately, though, this examiner indicated the pattern of left ear hearing loss shown was "less typical" of noise-induced hearing loss. In December 2008, so later that same year, the Veteran had another VA audiologic examination. Audiometric results were as follows: HERTZ 500 1000 2000 3000 4000 RIGHT 15 20 15 15 20 LEFT 20 20 25 25 35 Speech discrimination was 94 percent in the right ear and 96 percent in the left ear. The examiner indicated the current hearing loss was due to the aging process and not to the Veteran's service, as there was no hearing loss in service and since noise-induced hearing loss did not have a delayed onset. The additional evidence received since the RO's March 2004 rating decision still does not tend to establish the Veteran has sufficient hearing loss in his right ear to be considered an actual ratable disability according to the threshold minimum requirements of 38 C.F.R. § 3.385. Hence, just as when this component of his claim was previously considered, he has not established he has the alleged disability, that is, at least as concerning this particular ear (his right ear). Obviously then, without this required proof of current disability involving this ear, there necessarily cannot be attribution of this for all intents and purposes nonexistent disability and any disease, injury or event during or coincident with his military service like repeated exposure to extremely loud noise. Consequently, absent the required new and material evidence as concerning this ear, not just since the RO's prior, final and binding, March 2004 decision, but also since even receipt of the petition to reopen this claim, the claim as it relates to this ear cannot be reopened. See McClain v. Nicholson, 21 Vet. App. 319 (2007) (clarifying that this requirement of current disability is satisfied when the claimant has the disability at the time the claim for VA disability compensation is filed or during the pendency of the claim and that a claimant may be granted service connection even though the disability resolves prior to VA's adjudication of the claim). Conversely, not only is there affirmation he has sufficient hearing loss in his other ear (his left ear) to be considered a ratable disability by VA standards, again, meaning according to the threshold minimum requirements of 38 C.F.R. § 3.385, but there also is at least suggestion of a possible correlation between the hearing loss in this ear and an event - namely, noise exposure - which occurred during his military service. And although there is seeming difference of opinion concerning this, at least some of the evidence submitted since the RO's March 2004 decision tends to support this notion, so is new and material to the claim at least as concerning this other ear (the left ear). Specifically, although the December 2008 VA audiologic examiner opined that current hearing loss was not due to service and instead due to the aging process, meaning simply getting older, the April 2008 private examiner offered a contrary opinion partially favorable to the Veteran's claim indicating that the type of in-service noise exposure he had described could have caused his current hearing loss - although the type and pattern of left ear hearing loss shown admittedly was less typical of noise-induced hearing loss. This private examiner therefore concluded at least partially, albeit not entirely, favorable to the claim, which is still sufficient reason to reopen the claim in light of the holding in Shade. The Board is aware that the April 2008 opinion is similar to that offered by the December 2004 examiner, but it is more decisive and reasoned. Thus, it is qualitatively different from the December 2004 opinion and does not constitute cumulative evidence. Service Connection During the March 1968 military induction examination, no hearing loss was shown, and the Veteran's PULHES physical profile amounted to a "picket fence" (i.e., all 1's), indicating a high level of medical fitness. See generally Hanson v. Derwinski, 1 Vet. App. 512, 514 (1991) (explaining the military medical profile system). He began serving on active duty that same month. A January 1969 notation in the STRs revealed ear trouble caused by a blast concussion, and there was slight hemorrhaging of both eardrums. In February 1969 bilateral perforated tympanic membranes (eardrums) were noted. A February 1969 audiogram indicated the following results: HERTZ 500 1000 2000 3000 4000 LEFT 25 25 25 25 That month, the STRs indicated decreased hearing and bilateral tympanic membrane perforations. But by the time of his separation examination, the Veteran's ears were found to be normal, and his eardrums not perforated. As well, no hearing loss was found; indeed, the PULHES physical profile indicated a "1" for hearing, indicating the highest level of hearing. His military service ended in January 1970. There is no subsequent mention of hearing loss in either ear, either in the way of a relevant subjective complaint or objective clinical finding, for more than the next three decades (so greater than 30 years). During VA examination in January 2004, audiometric results were as follows: HERTZ 500 1000 2000 3000 4000 LEFT 10 15 15 10 20 Speech recognition on the left was 94 percent. The foregoing does not represent hearing loss as defined by VA regulation. 38 C.F.R. § 3.385. The Veteran described noise exposure in service to include as secondary to the blast that had caused his eardrum perforation. On physical examination, however, his tympanic membranes (eardrums) were described as normal. The examiner did not offer any opinion regarding the etiology of hearing loss, as none was found. December 2004 audiometric results were as follows: HERTZ 500 1000 2000 3000 4000 LEFT 15 20 20 30 35 Speech recognition was 92 percent on the left. The foregoing speech recognition score represents left ear hearing loss. 38 C.F.R. § 3.385. The accompanying report indicated that military noise exposure could not be ruled out as a causative factor of the Veteran's hearing loss. So there was not exclusion of his service as the source of the hearing loss in this ear, but there equally was not definitive indication of this purported relationship either. At most there was just suggestion, instead, of this possibility. An April 2008 private audiologic examination report indicated the following results: HERTZ 500 1000 2000 3000 4000 LEFT 20 20 30 30 40 Speech discrimination was 92 percent on the left. The examiner indicated that the type and degree of noise exposure experienced by the Veteran in service was sufficient to have caused the type of hearing loss suffered by him currently. But the examiner also stated that the configuration of left ear hearing loss was "less typical" of noise-induced hearing loss. So he seemingly ultimately disassociated the Veteran's left ear hearing loss from his military service. In December 2008, the Veteran was afforded another VA audiologic examination. Audiometric results were as follows: HERTZ 500 1000 2000 3000 4000 LEFT 20 20 25 25 35 Speech discrimination was 96 percent on the left. Thus, no left ear hearing loss was present for VA compensation purposes. 38 C.F.R. § 3.385. In any event, the examiner indicated that any current hearing loss was due to the aging process and not to service, as there was no hearing loss in service and noise-induced hearing loss did not have a delayed onset. The Veteran contrarily asserts that his left ear hearing loss was caused by noise exposure in service to include noise from the blast that caused perforated eardrums. Although lay persons are competent to provide opinions on some medical issues, see Kahana v. Shinseki, 24 Vet. App. 428, 435 (2011), the specific issue in this case, namely the etiology of his hearing loss, falls outside the realm of common knowledge of a lay person. See Jandreau v. Nicholson, 492 F.3d 1372, 1377 n.4 (Fed. Cir. 2007) (lay persons not competent to diagnose cancer). Thus, his lay assertions regarding the origins of his left ear hearing loss do not constitute competent evidence on this critical and dispositive issue. Whether he suffers from current left ear hearing loss sufficient to meet the threshold minimum requirements of § 3.385 is equivocal, as the latest audiometric testing results reflect normal hearing - or at least less hearing loss than is required by this governing VA regulation. However, as several prior tests revealed ratable left ear hearing loss for VA compensation purposes, the Board will resolve this doubt in his favor and assume he has sufficient hearing loss in this ear to be considered a ratable disability and satisfy the threshold minimum requirements of § 3.385. 38 U.S.C.A. § 5107; 38 C.F.R. § 3.102. There still has to be attribution of the hearing loss in this ear to his military service, however, and it is in this equally critical respect that the evidence is less favorable to his claim. The December 2004 examiner opined that military noise exposure could not be ruled out as a causative factor of the Veteran's hearing loss. This opinion is not decisive and on its own perhaps too speculative to be probative, as medical evidence that is speculative, general, or inconclusive in nature cannot support a claim. See 38 C.F.R. § 3.102 (noting that reasonable doubt does not include resort to mere speculation or remote possibility); see also Obert v. Brown, 5 Vet. App. 30, 33 (1993); Tirpak v. Derwinski, 2 Vet. App. 609, 611 (1992); and Bostain v. West, 11 Vet. App. 124, 127-28 (1998), quoting Obert, 5 Vet. App. at 33 (and collectively finding that a medical opinion expressed in terms of "may" also implies "may or may not" and is too speculative to establish medical nexus); Warren v. Brown, 6 Vet. App. 4, 6 (1993) (similarly finding that a doctor's statement framed in equivocal terms such as "could have been" is not probative). See, too, Beausoleil v. Brown, 8 Vet. App. 459, 463 (1996); Libertine v. Brown, 9 Vet. App. 521, 523 (1996). There are indeed even other precedent cases discussing the lesser probative value of opinions like this that are equivocal, in various contexts, which essentially state that it is possible that what posited is true. See, e.g., Stegman v. Derwinski, 3 Vet. App. 228, 230 (1992); Perman v. Brown, 5 Vet. App. 227, 241 (1993); Winsett v. West, 11 Vet. App. 420, 424 (1998). See, too, Bloom v. West, 13 Vet. App. 185, 187 (1999) (a medical opinion based on speculation, without supporting clinical data or other rationale, does not provide the required degree of medical certainty). Statements like this, which are inconclusive as to the origin of a disorder, generally cannot be employed as suggestive of a linkage between the disorder and the Veteran's military service. Warren, 6 Vet. App. at 6; Sklar v. Brown, 5 Vet. App. 104, 145-6 (1993). The same is true when an examiner concedes he cannot comment on etiology "without resorting to mere speculation." However, these types of opinions also cannot be used to rule out this purported correlation, either. Ultimately, noncommittal opinions like this amount to "nonevidence," neither for nor against the claim, because as explained, according to the holding in Bloom, service connection may not be based on speculation or remote possibility. See again also 38 C.F.R. § 3.102 (when considering application of the benefit-of-the-doubt doctrine, reasonable doubt is one within the range of probability, as distinguished from pure speculation or remote possibility). But having said all of that, consider as well that a "absolutely accurate" determination of etiology is not a condition precedent to granting service connection, nor is "definite" or "obvious" etiology. See Alemany v. Brown, 9 Vet. App. 518, 519 (1996). That is to say, use of cautious language does not always express inconclusiveness in a doctor's opinion. Rather, the opinion should be viewed in its full context and not characterized solely by the medical professional's choice of words. See Lee v. Brown, 10 Vet. App. 336, 338 (1997). Moreover, more recent case law suggests that caution must be exercised when referring to medical reports and opinions as "nonevidence" and that, instead, the probative value or weight (competency and credibility) of the evidence should be assessed. Notably for instance, in Hogan v. Peake, 544 F.3d 1295 (Fed. Cir. 2008), the Federal Circuit Court indicated a determination regarding service connection requires consideration of all pertinent medical and lay evidence, including medical opinions that do not state definitively when a particular disorder or condition began; therefore, classifying a medical opinion as "non-evidence" is "troubling." In Fagan v. Shinseki, 573 F.3d 1282 (Fed. Cir. 2009), the Federal Circuit Court more recently held that an examiner's statement, which recites the inability to come to an opinion, provides neither positive nor negative support for service connection; therefore, it is not pertinent evidence regarding service connection. The remainder of the report, however, must be considered as evidence of whether the disability was incurred in service. An even more recent precedent case also admonished the Board for relying on medical opinions that also were unable to establish this required linkage, that is, without resorting to mere speculation, as cause for denying the Veteran's claims. See Jones v. Shinseki, 23 Vet. App. 382 (2010). In Jones, the Court noted it was unclear whether the examiners were unable to provide this requested definitive medical comment on etiology because they actually were unable to since the limits of medical knowledge had been exhausted or, instead, for example, needed further information to assist in making this determination (e.g., additional records and/or diagnostic studies) or other procurable and assembled data. The Court in Jones acknowledged there are instances where a definitive opinion cannot be provided because required information is missing or can no longer be obtained or current medical knowledge yields multiple possible etiologies with none more likely than not the cause of the claimed disability. See Clemons v. Shinseki, 23 Vet. App. 1, 6 (2009) (noting the Board need not obtain further medical evidence where the medical evidence "indicates that determining the cause is speculative"). The Court in Jones held, however, that in order to rely upon a statement that an opinion cannot be provided without resort to mere speculation, it must be clear that the procurable and assembled data was fully considered and the basis for the opinion must be provided by the examiner or apparent upon a review of the record. Ultimately, the most that can be deduced from the December 2004 examiner's opinion is that military noise exposure could not be excluded as the source or cause of the Veteran's hearing loss, but this is not necessarily tantamount to saying it is the reason for his hearing loss, only that it is a possible reason, which, as explained, is insufficient to establish the required cause-and-effect correlation needed to show entitlement to service connection for this claimed disability. The April 2008 private examiner's opinion weighs against the claim because, although noise exposure admittedly could have caused the Veteran's left ear hearing loss, the particular configuration of his left ear hearing loss was "less typical" of noise-induced hearing loss, so not ultimately this etiology. The December 2008 VA examiner, despite finding no ratable left ear hearing loss according to VA regulation (§ 3.385), opined that any current hearing loss was due to the aging process and not to the Veteran's service, as there was no hearing loss in service and since noise-induced hearing loss did not have a delayed onset. The Veteran had a greater than 20-decibel loss in certain relevant frequencies during his service when examined in February 1969, in particular a 25-decibel loss in the 500, 1000, 2000 and 4000 Hertz frequencies (3000 was not measured), which, according to the holding in Hensley, indicates he had some measure of hearing loss in this ear during his service, seemingly contradicting what the December 2008 VA compensation examiner concluded. If only considering this, it would tend to undermine this VA examiner's opinion, but he also indicated that noise-induced hearing loss does not have a delayed onset. Therefore, even if accepting the indication of hearing loss during service was the result of noise exposure, so noise-induced, including especially because of the blast injury causing perforation of the Veteran's tympanic membranes (eardrums), it is not shown he continued to have hearing loss for the remainder of his service or even for many ensuing years, indeed, decades. So any hearing loss he experienced in service was acute and transitory, not instead chronic or permanent, and service connection is only granted for chronic residual disability. Notably, he had additional hearing evaluations subsequent to that trauma in service during which there was no further indication of hearing loss, including in this specific ear. So the VA examiner's ultimate determination that the Veteran's hearing loss in this ear is instead age related is consistent with this other evidence in the file, which shows far more recent onset of the current hearing loss. See Nieves-Rodriguez v. Peake, 22 Vet. App. 295, 301 (2008) (holding that a medical opinion should contain a conclusion and a reference to supporting data with a " reasoned medical explanation connecting the two."); Prejean v. West, 13 Vet. App. 444, 448-9 (2000) (holding that 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). For these reasons or bases, the most probative evidence weighs against the Veteran's claim of entitlement to service connection for left ear hearing loss. Because the preponderance of the evidence is against the claim, service connection for left ear hearing loss is denied. 38 C.F.R. § 3.303; see also 38 U.S.C.A. § 5107; 38 C.F.R. § 3.102; Alemany, supra. Increased Rating Disability evaluations are determined by evaluating the extent to which a Veteran's service-connected disability adversely affects his ability to function under the ordinary conditions of daily life, including employment, by comparing his symptomatology with the criteria set forth in the Schedule for Rating Disabilities (Rating Schedule). 38 U.S.C.A. § 1155; 38 C.F.R. §§ 4.1, 4.2, 4.10 (2012). In evaluating a disability, the Board considers the current examination reports in light of the whole recorded history to ensure that the current rating accurately reflects the severity of the condition. The Board has a duty to acknowledge and consider all regulations that are potentially applicable. Schafrath v. Derwinski, 1 Vet. App. 589 (1991). The medical as well as industrial history is to be considered, and a full description of the effects of the disability upon ordinary activity is also required. 38 C.F.R. §§ 4.1, 4.2, 4.10. A "staged" rating is appropriate for an increased-rating claim when the factual findings show distinct time periods when the service-connected disability exhibited symptoms that would warrant different ratings. Hart v. Mansfield, 21 Vet. App. 505 (2007). 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 required for that rating. Otherwise, the lower rating will be assigned. 38 C.F.R. § 4.7. All reasonable doubt material to the determination is resolved in the Veteran's favor. 38 C.F.R. § 4.3. In view of the number of atypical instances it is not expected, especially with the more fully described grades of disabilities, that all cases will show all the findings specified. Findings sufficiently characteristic to identify the disease and the disability therefrom, and above all, coordination of rating with impairment of function will, however, be expected in all instances. 38 C.F.R. § 4.21. The schedular criteria, effective as of November 7, 1996, incorporate the American Psychiatric Association 's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). 38 C.F.R. §§ 4.125, 4.130, Diagnostic Code 9411. A 50 percent rating is warranted for occupational and social impairment with reduced reliability and productivity due to such symptoms as: flattened affect; circumstantial, circumlocutory, or stereotyped speech; panic attacks more than once a week; difficulty in understanding complex commands; impairment of short- and long-term memory (e.g., retention of only highly learned material, forgetting to compete tasks); impaired judgment; impaired abstract thinking; disturbances of motivation and mood; difficulty in establishing and maintaining effective work and social relationships. Id. A higher 70 percent rating requires occupational and social impairment with deficiencies in most areas, such as work, school, family relations, judgment, thinking, or mood, due to such symptoms as: suicidal ideation; obsessional rituals which interfere with routine activities; speech intermittently illogical, obscure, or irrelevant; near- continuous panic or depression affecting the ability to function independently, appropriately and effectively; impaired impulse control (such as unprovoked irritability with periods of violence); spatial disorientation; neglect of personal appearance and hygiene; difficulty in adapting to stressful circumstances (including work or a work-like setting); and inability to establish and maintain effective relationships. Id. The criteria for a 70 percent rating are met if there are deficiencies in most of the areas of work, school, family relations, judgment, thinking, and mood. Bowling v. Principi, 15 Vet. App. 1, 11-14 (2001). Whereas the highest possible schedular rating of 100 percent requires total occupational and social impairment due to such symptoms as: gross impairment in thought processes or communication; persistent delusions or hallucinations; grossly inappropriate behavior; persistent danger of hurting self or others; intermittent inability to perform activities of daily living (including maintenance of minimal personal hygiene); disorientation to time or place; memory loss for names of close relatives, own occupation, or own name. 38 C.F.R. 4.130, Diagnostic Code 9411. In assessing the evidence of record, it is important to note that the Global Assessment of Functioning (GAF) scores have been considered. The GAF score is a scaled rating reflecting the "psychological, social, and occupational functioning on a hypothetical continuum of mental health- illness." Richard v. Brown, 9 Vet. App. 266, 267 (1996) (citing DIAGNOSTIC AND STATISTICAL MANUAL OF MENTAL DISORDERS, 4th ed. (DSM-IV) at 32). A GAF score of 39 to 40 indicates "some impairment in reality testing or communication (e.g., speech is at times illogical, obscure, or irrelevant) or major impairment in several areas, such as work or school, family relations, judgment, thinking, or mood (e.g., depressed man avoids friends, neglects family, and is unable to work; child frequently beats up other children, is defiant at home, and is failing at school)." Id. A GAF score of 41-50 indicates "serious symptoms (e.g., suicidal ideation, severe obsessional rituals, frequent shoplifting) OR any serious impairment in social, occupational, or school functioning (e.g., no friends, unable to keep a job)." Id. A GAF score of 51-60 indicates "Moderate symptoms (e.g., flat affect and circumstantial speech, occasional panic attacks) OR moderate difficulty in social, occupational, or school functioning, (e.g., few friends, conflicts with peers or co-workers)." Id. GAF scores that are between 61 and 70 reflect some mild symptoms (e.g., depressed mood and mild insomnia) or some difficulty in social, occupational, or school functioning (e.g., occasional truancy, or theft within the household), but generally functioning pretty well, and has some meaningful interpersonal relationships. Id. As evidenced by use of the phrase "such symptoms as", the list of symptoms in the rating criteria is meant to be mere examples of symptoms that would warrant a particular evaluation, so are not meant to be exhaustive, and the Board need not find all or even some of the symptoms to award a specific evaluation. If the evidence shows the Veteran suffers symptoms or effects that cause occupational or social impairment equivalent to what would be caused by the symptoms listed in the diagnostic code, the appropriate equivalent rating will be assigned. Mauerhan v. Principi, 16 Vet. App. 436, 442-3 (2002). The Federal Circuit Court has embraced the Mauerhan Court's interpretation of the criteria for rating psychiatric disabilities. Sellers v. Principi, 372 F.3d 1318, 1326 (Fed. Cir. 2004). Although the Veteran's symptomatology is the primary consideration, the Veteran's level of impairment must be in "most areas" applicable to the relevant percentage rating criteria. Vazquez-Claudio v. Shinseki, 2012-7114 (Fed. Cir. Apr. 8, 2013). Factual Background The Veteran has a 50 percent rating for his PTSD. 38 C.F.R. § 4.130, Diagnostic Code 9411. In February 2008, the Veteran reported that his longest period of employment was for 32 years. His most recent job was as a substitute teacher, and he reported that for the previous three years he had been working on a part-time basis. He was also in receipt of a pension. He had received treatment for alcohol and drug abuse, although the latter was less of a problem. He reported significant problems getting along with his wife and child. He reported serious anxiety and tension and that he was taking psychotropic medication. He denied suicidal ideation as well as a history of attempts. An April 2008 note from MM, Ph.D., a private psychologist, indicated that the Veteran had episodes of significant depression. He was anxious and uncomfortable in crowds. He experienced sleep disturbances and nightmares, and he had frequent intrusive thoughts associated with his combat experiences. He was hypervigilant and experienced guilt. There was episodic alcohol abuse, which caused considerable conflict in his relationships. Dr. MM opined that a higher rating was warranted, to include a TDIU rating. A June 2008 VA notation indicated that the Veteran was participating in a substance abuse therapy group. In June and July 2008, the Veteran admitted himself for inpatient PTSD treatment. The Veteran described feelings of isolation and apathy. He could not tolerate losing. The Veteran indicated that he had a low mood, and his ability to concentrate was poor. He had poor sleep and experienced nightmares. He had difficulty with chronic irritability. He was hypervigilant and highly anxious. He felt detached from others, and his only significant attachment was to his spouse. The Veteran had intrusive recollections of combat and suffered from flashbacks. Running kept him "sane" and was a religion to him. The Veteran was interested in running, reading, and writing. The Veteran denied suicidal ideation but indicated that his drinking might have been a slow suicide wish. He denied hallucination, delusions, or paranoia. The Veteran stated that he was a retired mailman and currently worked as a substitute teacher on a part-time basis. The Veteran had been involved in outpatient PTSD and substance abuse treatment. On discharge, the diagnosis was of chronic PTSD, recurrent moderate major depressive disorder secondary to PTSD, and alcohol dependence that was in remission for approximately four months. The examiner assessed a GAF score of 40 and indicated that the highest GAF applicable in the last year was 40. In July 2008, the Veteran's wife wrote that the Veteran began to isolate himself from others by provoking them into confrontations. The Veteran was unable to express emotion unless drinking. The Veteran's drinking became much worse when he retired. Several incidents that occurred during drunken episodes caused his daughter to prevent him from seeing his grandson. During teaching assignments, the Veteran challenged students who "disrespected" him, and he was not invited back to teach at several schools. The Veteran had trouble concentrating and had nightmares. His sleep, however, had improved with medication. The Veteran's wife suggested that the Veteran's PTSD in conjunction with his alcohol abuse had a negative impact upon his ability to work. On September 2008 VA PTSD examination, the Veteran indicated that he was engaged in substitute teaching. The Veteran admitted to drinking heavily on a weekly basis. The Veteran indicated that he had a few friends and that he ran with his dog. The Veteran asserted that he attended weekly support group meetings but did not consider himself a joiner. The Veteran was dressed appropriately and well groomed. He was fully oriented. He was cooperative, displayed good eye contact, and his speech was clear and coherent. There were no delusions, hallucinations, or other psychotic symptoms. Short term memory was good, but he complained of forgetfulness. His mood was euphoric. He laughed even when discussing traumatic events. He perseverated on thoughts of combat. His sleep was disturbed, and insight and judgment were poor. He was anxious and hypervigilant. The Veteran could become confrontational, even toward children, which happened during teaching. He had difficulty getting along with others due to his short fuse. The Veteran engaged in risky activities but denied being suicidal. The Veteran was isolated and felt emotionally detached. The examiner diagnosed chronic PTSD that he described as moderate, bipolar disorder 1, and alcohol dependence. He assigned a GAF score of 50. The examiner indicated that the Veteran was capable of handling his funds and that he was self medicating with alcohol. She suggested that he had difficulty relating to others as well as rigid thinking and beliefs and that lack of anger control had an impact on his ability to work on a full-time basis. Other symptoms had an impact socially. The Veteran was experiencing difficulty adjusting to aging. In June 2009, the Veteran requested a note from a VA mental health professional stating that he was not suicidal or homicidal so that he could enter an in-patient VA PTSD treatment program. An August 2009 letter from the therapists treating the Veteran's wife indicated that physical altercations between her and the Veteran were usually fueled by alcohol. In October 2009, the Veteran entered the VA in-patient treatment program. The Veteran reported that his most pressing issues were isolation and relational difficulties with his daughter. The Veteran reported a history of several psychotropic medication. On admission, however, he was not taking any medication, and he declined to use psychotropic medication during the admission. The Veteran felt hopelessness and anhedonia. His sleep was disturbed, and he had trouble concentrating. The Veteran denied suicidal ideation but stated that his heavy alcohol use throughout the years may have been a slow death wish. He indicated that he engaged in risky behavior when drinking to include becoming confrontational. There was some psychomotor restlessness. The examiner noted a history of previous in-patient admissions, but none was for acute care associated with PTSD. The examiner noted as well that the Veteran pursued outpatient PTSD treatment for a number of years. The Veteran admitted to excessive drinking although he denied alcohol use in the previous two months. The Veteran's eye contact was good, his speech was normal, he was appropriately dressed and groomed, and there was no evidence of psychosis. He had a restricted affect, dysphoric mood, and mild psychomotor agitation. Insight and judgment were fair. Memory and cognition were intact, and attention and concentration were adequate. The diagnosis was of chronic PTSD, recurrent moderate major depressive disorder secondary to PTSD, and alcohol dependence in remission for two months. The examiner assigned a GAF score of 40. A November 2009 program treatment note indicated that the Veteran's reported PTSD symptoms severely impaired his ability to function socially and occupationally. The note writer indicated that the Veteran's admission GAF score was 40. In a November 2009 statement, a VA addiction therapist who treated the Veteran during his in-patient stay. The therapist indicated that the Veteran had physical altercations with his wife and that he was estranged from his daughter. The addiction therapist indicated that the Veteran saw the program as a way to avoid some of his irrational suicidal thoughts. The Veteran's reckless behavior included excessive drinking, occasional marijuana use, driving while intoxicated, blackouts, and combativeness. The addiction therapist stated that the Veteran's behavior while drunk amounted to a form of suicide. The addiction therapist opined that the Veteran was able to grasp treatment alternatives to drinking but resisted those options. According to him, the Veteran could not be expected to obtain gainful employment due to his PTSD, substance abuse, and depression. In November 2009, two other VA mental health professionals who treated the Veteran during his recent admission indicated that the Veteran experienced the full range of PTSD symptoms to include reexperiencing, avoidance of stimuli associated with painful experiences, increased arousal, numbing of general responsiveness, severe sleep disturbance, increased anxiety, an inability to maintain employment, and an inability to sustain meaningful relationships. The Board notes that prior information in the claims file reveals that the Veteran has been married well in excess of 30 years. The writers indicated that the Veteran's PTSD symptoms were severe since service in Vietnam. In a December 2009 written statement, the Veteran's wife spoke of the Veteran's drinking, lack of motivation, and isolation from family. He drank and behaved inappropriately in the presence of his grandson. He was extremely argumentative and experienced increased trouble sleeping. An undated letter from a VA nurse practitioner indicated that due to the severity of the Veteran's PTSD, he was considered unemployable. His GAF was estimated as 40, and agitation and frequent conflict with family were cited. According to a March 2010 VA progress note, the Veteran indicated that he was stable if he isolated himself. He was no longer working as a substitute teacher because he had been in several confrontations with students. The Veteran was on no medication and continued to run daily. The Veteran was alert and well groomed. Mood was dysphoric, and affect was congruent with mood. The Veteran denied suicidal ideation. There was no psychosis. There was poor judgment with alcohol consumption. Memory impairment was minimal. The diagnosis was of PTSD with chronic periodic alcohol abuse. During a May 2010 VA psychiatric examination, the Veteran asserted that he was unemployable. The Veteran stated that he had been drinking frequently and heavily in recent years. He was becoming more withdrawn, stopped running, and asked his wife to move to a remote area. The Veteran was taking psychotropic medication. On examination, the Veteran was unshaven and had long hair. However, he was neatly dressed and displayed adequate hygiene. Speech was normal, and the Veteran displayed good eye contact. There was no sign of memory impairment. The Veteran indicated that he was depressed but not hopeless. He was motivated for treatment. He did not show any signs of agitation or restlessness, and the Veteran adamantly denied suicidal ideation. The examiner diagnosed PTSD with periodic acute exacerbations and assigned a GAF score of 45. The examiner stated that it was difficult to differentiate symptoms of PTSD from those of the nonservice-connected psychiatric disorders. The examiner indicated that alcohol use specifically was causing interpersonal problems with his wife and caused decreased motivation. The Veteran was fully capable of handling his finances. In June 2010, the Veteran's GAF score was assessed as 55. He reported emotional distancing and reexperiencing. In July 2012, the Veteran's son in law wrote that the Veteran behaved inappropriately around his grandchildren and in a manner that frightened them. During his November 2012 hearing, the Veteran testified that he experienced panic attacks. He stated that he would get disoriented and lost. He stated that his anger management problems had intensified and that he had confrontations with students he was teaching. Discussion The Veteran's confrontational behavior has been linked to his alcohol abuse. But to the extent his PTSD symptoms cannot be distinguished from other psychiatric diagnoses, the Board will consider the symptoms in question as part and parcel of his service-connected PTSD. See Mittleider v. West, 11 Vet. App. 181, 182 (1998) (holding that when it is not possible to separate the effects of a service-connected disability and a nonservice-connected disability, reasonable doubt must be resolved in the appellant's favor and the symptoms in question attributed to the service-connected disability). The Board finds that there was some hyperbole involved in the note of the VA addiction therapist. For example, he spoke of suicidality when the Veteran has consistently denied suicidal ideation. Indeed, just prior to admission he denied suicidal ideation and homicidal ideation. While the Veteran might have likened his drinking to a "death wish," he does not appear to have ever contemplated or attempted suicide. That however notwithstanding, the Board finds that the Veteran's service-connected PTSD more nearly approximates the level necessary for a 70 percent disability evaluation. 38 C.F.R. § 4.130, Diagnostic Code 9411. The Board recognizes that he does not suffer from suicidal ideation, obsessional rituals, abnormal speech, or an inability to function independently. The record does however reflect impaired impulse control as demonstrated by his tendency to become confrontational and an inability to establish effective relationships as apparent from the statements from his wife and son in law. While he has suggested an inability to adapt to stressful circumstances, work-related conflict may well have been related to his abuse of alcohol. In any event, the Board notes that he has been hospitalized twice during the appeal period, and inappropriate behavior or an inability to adapt to an inherently stressful situation was not shown. He indicated that he had panic attacks while testifying during his hearing before the Board. There are no clinical records indicating panic attacks, however. As well, he hinted at disorientation and needing his wife's help to get around, but there is no clinical evidence of that manifestation of mental illness in the record. Despite his apparent exaggeration of symptoms, at least to some extent, the Board finds that his symptoms are nonetheless sufficient to warrant a higher 70 percent evaluation, though not an even higher 100 percent evaluation. The Board makes this finding based on his apparent isolation, with the exception of his wife, and due to his consistently low GAF scores showing mostly major or serious impairment in several areas. Based on his credible symptomatology and GAF scores, the Board concludes that his PTSD disability picture more closely resembles that necessary for a 70 percent evaluation. 38 C.F.R. §§ 4.7, 4.140, Diagnostic Code 9411. The 70 percent evaluation is applicable throughout because his symptoms have been fairly consistent. Hart, supra. An even higher 100 percent evaluation is not warranted because the type of social and occupational impairment contemplated at this extreme level must be totally disabling. He is not totally impaired in these arenas. He is able to handle his finances independently. He has exhibited sufficient insight to seek PTSD treatment. His speech and thought processes have never been characterized as abnormal, and evidence of psychosis is completely absent. Furthermore, he is not in persistent danger of hurting himself or others. His memory is intact, and there is no sign that he is unable to accomplish the activities of daily living independently. The Board emphasizes that he apparently has been able to function adequately even during periods without psychotropic medication. In short, therefore, the criteria for an even higher 100 percent evaluation are not met at any time during the appeal period. Id.; 38 C.F.R. §§ 4.7, 4.140, Diagnostic Code 9411. In making this determination, the Board has considered the provisions of 38 U.S.C.A. § 5107(b) and 38 C.F.R. § 4.3, but there is not such a state of approximate balance of the positive evidence with the negative evidence to otherwise warrant an even more favorable decision. Extraschedular Consideration In exceptional cases an extraschedular rating may be provided. 38 C.F.R. § 3.321 (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. Therefore, initially, 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. Thun v. Peake, 22 Vet. App. 111 (2008). Under the approach prescribed by VA, if the criteria reasonably describe the claimant's disability level and symptomatology, then the claimant's disability picture is contemplated by the rating schedule, the assigned schedular evaluation is, therefore, adequate, and no referral is required. In the second step of the inquiry, however, if the schedular evaluation does not contemplate the claimant's level of disability and symptomatology and is found inadequate, the RO or Board must determine whether the claimant's exceptional disability picture exhibits other related factors such as those provided by the regulation as "governing norms." 38 C.F.R. 3.321(b)(1) (related factors include "marked interference with employment" and "frequent periods of hospitalization"). When the rating schedule is inadequate to evaluate a claimant's disability picture and that picture has related factors such as marked interference with employment or frequent periods of hospitalization, then the case must be referred to the Under Secretary for Benefits or the Director of the Compensation and Pension Service for completion of the third step-a determination of whether, to accord justice, the claimant's disability picture requires the assignment of an extraschedular rating. Id. In Mittleider, the Court held that the benefit-of-the-doubt applies to determinations of whether a symptom should be attributed to a service-connected condition. Id. at 182. So, with this in mind, the Board has considered Mittleider and has attributed all potentially service-connected symptoms to one service-connected condition or another, in considering whether the Veteran is entitled to an extraschedular rating. Turning to the first step of the extraschedular analysis articulated in Thun, the Board finds that the symptomatology and impairment caused by the Veteran's PTSD is specifically contemplated by the schedular rating criteria, so no referral for extraschedular consideration is required. The schedular rating criteria, expressed in Diagnostic Code 9411, specifically provide for disability ratings based on a combination of history and clinical findings. In this case, considering the lay and medical evidence, the Veteran's PTSD has manifested in fraught relationships, isolation, sleep impairment, intrusive thoughts, avoidance of distressing stimuli, and occasional nightmares and flashbacks along with very material psychosocial impairment. These symptoms and areas of impairment are either explicitly part of the schedular rating criteria or are "like or similar to" those symptoms and impairment explicitly listed in the schedular rating criteria. Mauerhan, 16 Vet. App. at 443. The levels of occupational and social impairment are also explicitly part of the schedular rating criteria. Vazquez-Claudio, supra. In addition, the GAF scores are incorporated as part of the schedular rating criteria as they tend to show the overall severity of symptomatology or overall degree of impairment in occupational and social functioning. The schedule is intended to compensate for average impairments in earning capacity resulting from service- connected disability in civil occupations. 38 U.S.C.A. § 1155. "Generally, the degrees of disability specified [in the rating schedule] are considered adequate to compensate for considerable loss of working time from exacerbations or illnesses proportionate to the severity of the several grades of disability." 38 C.F.R. § 4.1. In this case, the problems reported by the Veteran are specifically contemplated by the criteria discussed above, including the effect on his daily life. In the absence of exceptional factors associated with an acquired psychiatric disorder, the Board finds that the criteria for submission for assignment of an extraschedular rating pursuant to 38 C.F.R. § 3.321(b)(1) are not met. See Bagwell v. Brown, 9 Vet. App. 337 (1996); Shipwash v. Brown, 8 Vet. App. 218, 227 (1995). ORDER No new and material evidence having been received, the claim of entitlement to service connection for right ear hearing loss is not reopened and remains denied. New and material evidence having been received, the claim of entitlement to service connection for left ear hearing loss is reopened. But service connection for left ear hearing loss is denied. A higher 70 percent rating is granted for the service- connected PTSD, subject to the statutes and regulations governing the payment of VA compensation. REMAND A remand is required to ensure there is a complete record upon which to decide the Veteran's remaining claims. VA has a duty to make reasonable efforts to assist him in obtaining evidence necessary to substantiate a claim for the benefit sought, unless no reasonable possibility exists that such assistance would aid in substantiating the claim. 38 U.S.C.A. § 5103A(a); 38 C.F.R. § 3.159(c), (d). He claims entitlement to service connection for tinnitus. The record reveals, however, that VA denied entitlement to service connection for tinnitus in a prior March 2004 rating decision. And as he did not perfect an appeal in response to that prior rating decision, it is a final and binding decision based on the evidence then of record. 38 U.S.C.A. § 7105 (West 2002); 38 C.F.R. §§ 3.104(a), 3.160(d), 20.200, 20.1103. So to reopen this claim and warrant further consideration of it on its underlying merits, there has to be new and material evidence. 38 U.S.C.A. § 5108; 38 C.F.R. § 3.156. As already explained, VA has a duty to assist claimants in substantiating their claims for benefits. This duty to assist often requires a VA examination for a medical opinion. 38 C.F.R. § 3.159(c)(4). However, this regulation does not require that the appellant be provided a VA examination until new and material evidence has been submitted. 38 C.F.R. § 3.159(c)(4)(iii). Notably, however, once VA undertakes the effort to provide an examination when developing a service-connection claim, even if not statutorily obligated to do so, it must provide an adequate one, else, notify the Veteran why one cannot or will not be provided. See Barr, 21 Vet. App. at 312. In this case, the Veteran was afforded a VA audiologic examination in December 2008. The examiner indicated, in essence, that tinnitus had many potential etiologies and that she could not opine regarding the etiology of the Veteran's tinnitus "without resorting to mere speculation." But as already discussed, an examination report is not inadequate, per se, merely because an examiner concludes that he or she is unable to offer a nonspeculative opinion. Rather, the Court has held that, if an examiner concludes that a nonspeculative opinion cannot be offered, he or she must explain the basis for such a conclusion or the basis must otherwise be apparent from the evidence. Jones v. Shinseki, 23 Vet. App. 382, 390 (2010). Thus, to be adequate, more than a conclusion needs to be expressed by the examiner that the etiology of a particular condition is not known or is unknowable. Stefl v. Nicholson, 21 Vet. App. 120, 124 (2007). Rather, a sufficient rationale and supporting explanation must be provided that address such matters as whether there is inadequate factual information, whether the question falls within the limits of current medical knowledge or scientific development, whether the cause of the condition in question is truly unknowable, and whether the question is so outside the norm of practice that it is really impossible for the examiner to use his or her medical expertise and training to arrive at an opinion. Jones, supra (to rely on a statement that an opinion cannot be provided without resort to mere speculation, it must be clear that the procurable and assembled data was fully considered and the basis for the opinion must be provided by the examiner or be apparent upon a review of the record.) Here, it is unclear from the record why the VA examiner could not provide a medical opinion without resorting to speculation. The Board merely requires an opinion regarding whether it is at least as likely as not (50 percent or greater likelihood) that the Veteran's tinnitus is related to his service. Thus, while there might be other potential causes, that question must still be answered unless a response is truly beyond the scope of current medical knowledge. Because the December 2008 VA findings concerning tinnitus are inadequate, a new VA examination is in order. Moreover, because the additional matter of entitlement to a TDIU also is at issue, the examiner will be asked to opine regarding the impact of the tinnitus on employability. Further concerning this derivative claim of entitlement to a TDIU, it, too, requires further information. The Veteran alleges that he is unemployable due to his service-connected PTSD especially. Indeed, that disability is now rated higher, as 70-percent disabling, as a result of this decision. However, the Board notes that a review of the record reveals the Veteran has a history of substance abuse and alcohol abuse in particular. Most recently, he worked as a substitute teacher but quit for fear that he would become belligerent. It is unclear whether his reluctance to teach stems from PTSD symptoms or from other nonservice-connected symptoms such as those related to his alcohol abuse or other nonservice-connected conditions. As a general proposition, no compensation shall be paid if the disability resulting from injury or disease in service is a result of the Veteran's willful misconduct or abuse of alcohol or drugs. 38 U.S.C.A. §§ 105, 1110. Direct service connection may be granted only when a disability was incurred or aggravated in the line of duty, and not the result of the Veteran's willful misconduct or, for claims filed after October 31, 1990, the result of his abuse of alcohol or drugs. 38 C.F.R. § 3.301. Regarding drug usage, the isolated and infrequent use of drugs by itself will not be considered willful misconduct; however, the progressive and frequent use of drugs to the point of addiction will be considered willful misconduct. Where drugs are used to enjoy or experience their effects and the effects result proximately and immediately in disability or death, such disability or death will be considered the result of the person's willful misconduct. Organic diseases and disabilities that are a secondary result of the chronic use of drugs and infections coinciding with the injection of drugs will not be considered of willful misconduct origin. (See paragraph (d) of this section regarding service connection where disability is a result of abuse of drugs.). Where drugs are used for therapeutic purposes or where use of drugs or addiction thereto, results from a service-connected disability, it will not be considered of misconduct origin. 38 C.F.R. § 3.301(c)(3). So disability resulting from alcohol or drug abuse, since it is willful misconduct, generally cannot be service connected. 38 U.S.C.A. § 105(a); 38 C.F.R. §§ 3.1(m) and (n), 3.301(d), 3.303(c)(3) and (d). VA's General Counsel has confirmed that direct service connection for disability or death that is a result of abuse of alcohol or drugs is precluded for purposes of all VA benefits for a claim, as here, filed after October 31, 1990. See VAOPGCPREC 7-99 (June 9, 1999); VAOPGCPREC 2-98 (Feb. 10, 1998). There is a very limited exception to this general rule. In Allen v. Principi, 237 F.3d 1368 (Fed. Cir. 2001), the Federal Circuit Court held that compensation could not be awarded pursuant to 38 U.S.C.A. § 1110 and 38 C.F.R. § 105(a) either for a primary alcohol/drug abuse disability incurred during service or for any secondary disability that resulted from primary alcohol/drug abuse during service. Id., at 1376. However, the Federal Circuit Court further held that there can be service connection for compensation for an alcohol/drug abuse disability acquired as secondary to, or as a symptom of, a non-willful misconduct, service- connected disability. But in further clarifying this, the Federal Circuit Court explained that claimants may only recover if they can adequately establish that the alcohol or drug abuse disability is secondary to or is caused by their primary service-connected disorder. Id., at 1381. An award of compensation on such a basis would only result where there is clear medical evidence establishing that the alcohol or drug abuse disability is indeed caused by a Veteran's primary service-connected disability, and where the alcohol or drug abuse disability is not due to willful wrongdoing. Id. To summarize, where drug and alcohol abuse is at issue, service connection is precluded "in two situations: (1) for primary alcohol abuse disabilities; and (2) for secondary disabilities (such as cirrhosis of the liver) that result from primary alcohol abuse." Allen, 237 F.3d at1376. Service connection is not precluded if alcohol abuse is secondary to a service-connected disability [such as, here, PTSD.] Id. Even if a Veteran has a service-connected disability, however, service connection would be precluded for the alcohol or drug abuse disability if it is actually due to willful action rather than the result of the service- connected disability. Id., at 1378. As it stands, the record contains no comprehensive examination and opinion regarding whether the Veteran's service-connected PTSD, in and of itself, prevents him from securing or following a substantially gainful occupation. See generally 38 C.F.R. § 4.16(a) (2012). An examination with an opinion answering this question is necessary. To ensure the record is complete, VA clinical records dated from July 14, 2011 to the present must be obtained and associated with the claims file for consideration. See 38 C.F.R. § 3.159(c)(2); Murphy v. Derwinski, 1 Vet. App. 78, 81-82 (1990) (holding that all VA treatment records that could potentially be helpful in resolving a claim must be obtained); see also Dunn v. West, 11 Vet. App. 462, 466-67 (1998); Bell v. Derwinski, 2 Vet. App. 611, 613 (1992) (records generated by VA facilities that may have an impact on the adjudication of a claim are considered in the constructive possession of VA adjudicators during the consideration of a claim, regardless of whether those records are physically on file). Accordingly, these remaining claims are REMANDED for the following additional development and consideration: 1. Obtain and associate with the claims file all VA clinical records dated from July 14, 2011 to the present. Since these records are in the custody of a Federal department or agency, namely VA, the attempts to obtain them are governed by 38 C.F.R. § 3.159(c)(2). Thus, make as many attempts to obtain these records (assuming they exist) as are necessary according to this VA regulation. Also appropriately notify the Veteran if unable to obtain these records after the required attempts. 38 C.F.R. § 3.159(e)(1). 2. Upon receipt of all additional records, schedule an appropriate VA examination to determine whether the Veteran's tinnitus is at least as likely as not (50 percent or greater likelihood) related or attributable to his military service. Based on what the prior VA compensation examiner indicated, the Board is aware that there are a number of possible causes of tinnitus. The examiner, however, must make all efforts to respond to the Board's inquiry regarding this determinative issue of etiology. The term "at least as likely as not" does not mean merely within the realm of medical possibility, rather, that the weight of medical evidence both for and against a conclusion is so evenly divided that it is as medically sound to find in favor of causation as it is to find against it. Because the Veteran also is claiming entitlement to a TDIU, if the examiner finds that the Veteran's tinnitus is at least as likely as not related to his military service, i.e., a service- connected disability in addition to his PTSD, then the examiner must provide an opinion regarding the impact if any of the tinnitus on employability when considered in combination with the PTSD. Explanatory rationale for all opinions and conclusions must be provided. The examination report must indicate whether pertinent records in the claims file were reviewed in conjunction with the examination. In the event that an opinion cannot be rendered without resorting to speculation, the examiner should explain why it would be speculative to respond and why an answer would be beyond the scope of current medical knowledge. So merely indicating he/she cannot respond will not suffice. 3. Also schedule a VA medical examination for an opinion regarding whether it is at least as likely as not (50 percent or greater likelihood) that the Veteran's service-connected PTSD, in and of itself, prevents him from obtaining or maintaining employment that could be considered substantially gainful versus just marginal in comparison. To reiterate, the term "at least as likely as not" does not mean merely within the realm of medical possibility, rather, that the weight of medical evidence both for and against a conclusion is so evenly divided that it is as medically sound to find in favor of that conclusion as it is to find against it. Explanatory rationale for all opinions and conclusions must be provided. The examination report must indicate whether pertinent records in the claims file were reviewed in conjunction with the examination. In the event that an opinion cannot be rendered without resorting to speculation, the examiner should explain why it would be speculative to respond and why an answer would be beyond the scope of current medical knowledge. So merely indicating he/she cannot respond will not suffice. 4. After completing the requested action, and any additional notification and/or development deemed warranted, readjudicate these remaining claims in light of all the evidence of record. If these remaining claims continue to be denied, send the Veteran and his representative an SSOC and give them time to submit additional evidence and/or argument in response before returning the file to the Board for further appellate consideration of these claims. The Veteran has the right to submit additional evidence and argument concerning these claims the Board is remanding. Kutscherousky v. West, 12 Vet. App. 369 (1999). These claims must be afforded expeditious treatment. The law requires that all claims that are remanded by the Board or by the Court for additional development or other appropriate action must be handled in an expeditious manner. See 38 U.S.C.A. §§ 5109B, 7112 (West Supp. 2012). ______________________________________________ KEITH W. ALLEN Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
