                              On Appeal from the Board of Veterans' Appeals

(Argued August 22, 2019                                                            Decided December 19, 2019)

      Alyse E. Galoski, with whom Kaitlyn C. Degnan was on the brief, both of Providence,
Rhode Island, for the appellant.

Ann Flynn, Chief Counsel; and James B. Cowden, Deputy Chief Counsel, were on the brief, all of
Washington, D.C., for the appellee.

         Before BARTLEY, Chief Judge, and PIETSCH and MEREDITH, Judges.

         BARTLEY, Chief Judge: Veteran Justiniano Delrio appeals through counsel a
September 19, 2017, Board of Veterans' Appeals (Board) decision denying entitlement to a total
disability evaluation based on individual unemployability (TDIU) on an extraschedular basis prior
to October 11, 2006, the effective date of his grant of service connection for fibromyalgia. Record
(R.) at 2-15.1 This appeal, over which the Court has jurisdiction pursuant to 38 U.S.C. §§ 7252(a)
and 7266(a), was referred to a panel of the Court, with oral argument, to address whether the
effective date of an extraschedular award of TDIU can be earlier than the date of service connection
for the disability or disabilities upon which the TDIU award was based. We conclude that it
cannot. Nevertheless, because the Board provided inadequate reasons or bases for its conclusion
that the veteran was not entitled to TDIU prior to October 11, 2006, based on his service-connected
post-traumatic stress disorder (PTSD) alone, we must set aside that portion of the September 2017



         1
            In the same decision, the Board granted entitlement to TDIU on an extraschedular basis from October 11,
2006, to July 28, 2015. R. at 15. To the extent that that determination is favorable to the veteran, the Court will not
disturb it. See Medrano v. Nicholson, 21 Vet.App. 165, 170 (2007) ("The Court is not permitted to reverse findings
of fact favorable to a claimant made by the Board pursuant to its statutory authority.").
Board decision and remand that matter for further development, if necessary, and readjudication
consistent with this decision.


                                             I. FACTS
       Mr. Delrio served on active duty in the U.S. Army from July 1974 to July 1976, with
subsequent service in the Army National Guard. R. at 841-42, 924. He also served on active duty
from January to July 1991. See R. at 1602.
       This appeal stems from a July 1996 claim for service connection for PTSD. R. at 2659-62.
In June 2005, a VA regional office (RO) granted that claim and assigned a 10% evaluation, R. at
1911-14, 1917-23, based, in part, on a March 2003 VA examination that noted memory problems,
disorientation, confusion, depression, avoidant behavior, and social isolation. R. at 1959-60. As
relevant here, the examiner opined that the veteran's "avoidant non-social behavior" and lumbar
and cervical spine disabilities "reduce[d] his employability." R. at 1960.
       Mr. Delrio timely appealed that 10% evaluation and was subsequently afforded additional
VA PTSD examinations in November 2005 and August 2008. The November 2005 examiner
recorded psychiatric symptoms similar to those noted in March 2003, R. at 437-38, and concluded
that those symptoms caused an "inability to function in a social as well as economic setting" due
to "fear of friendship, anger, depression[,] and asocial behavior," R. at 438-39. The August 2008
examiner stated that the veteran's PTSD caused a "[d]ecline in functioning and quality of life" but
opined that the condition did not cause total occupational and social impairment or occupational
and social impairment with deficiencies in most areas. R. at 1560. Based on these examinations
and other evidence of record, see, e.g., R. at 178-83, 312-20, 2330, Mr. Delrio was ultimately
awarded a higher initial evaluation of 30% effective September 8, 1999—the date he was first
diagnosed with PTSD—and an increased 50% evaluation effective July 29, 2015—the date of
another VA examination showing worsening. R. at 70-96, 287-307.
       Meanwhile, during his appeal of the PTSD evaluation, Mr. Delrio submitted a statement in
support of claim (SSC) in October 2006 requesting service connection for Gulf War Illness with
multiple joint pain and fibromyalgia. R. at 1739-41. The RO granted him service connection for
fibromyalgia in July 2007, assigning a 10% evaluation effective October 11, 2006, the date the RO
received the SSC. R. at 1596-612. He filed another SSC in October 2008 requesting an increased




                                                 2
rating, R. at 1533, and was ultimately awarded an increased 40% fibromyalgia evaluation effective
October 29, 2008, the date VA received his request, R. at 287-307.
         In June 2013, the Board, while processing those appeals, determined that the record had
reasonably raised the issue of entitlement to TDIU and remanded that inextricably intertwined
issue for initial development and adjudication. R. at 1176, 1179. Although not noted by the Board,
the evidence of record at that time included an April 1996 employer disability evaluation finding
that the veteran was unable to engage in stress situations or interpersonal relations due to a
"mental/nervous impairment," R. at 2044-45; a November 1996 statement from a former
supervisor indicating that the veteran's performance had recently declined and that he had become
less willing to complete work tasks, R. at 2461; a July 1997 Social Security Administration (SSA)
decision awarding disability insurance benefits based, in part, on major depression, R. at 2326-34;
and an August 2003 VA PTSD community care note documenting the veteran's report that his last
employer "encouraged him to retire due to increased anger and irritability which affected his
work," R. at 513.
         The RO denied entitlement to TDIU in September 2015, R. at 287-307, and the case was
returned to the Board. In December 2016, the Board awarded TDIU on a schedular basis effective
July 29, 2015, the date that the veteran's combined disability evaluation met the numeric evaluation
requirements of 38 C.F.R. § 4.16(a).2 R. at 92-95. The Board remanded for extraschedular referral
the issue of entitlement to TDIU prior to that date, R. at 95-96, and the VA Compensation Director
subsequently determined that an extraschedular TDIU award was not warranted for that period,
R. at 34-38. In April 2017, the Appeals Resource Center issued a Supplemental Statement of the
Case denying extraschedular TDIU prior to July 29, 2015, R. at 22-33, and the case was sent back
to the Board for appellate consideration.
         In September 2017, the Board issued the decision currently on appeal. R. at 2-15. The
Board reviewed the evidence of record and awarded extraschedular TDIU effective October 11,
2006, the effective date of Mr. Delrio's grant of service connection for fibromyalgia, because the


         2
            Section 4.16(a) states that TDIU will be awarded when a veteran is "unable to secure or follow a
substantially gainful occupation as a result of service-connected disabilities" and either has a single disability "ratable
at 60[%] or more" or one disability "ratable at 40[%] or more, and sufficient additional disability to bring the combined
rating to 70[%] or more." 38 C.F.R. § 4.16(a) (2019); see Youngblood v. Wilkie, 31 Vet.App. 412, 416 (2019). If a
veteran is "unemployable by reason of service-connected disabilities, but . . . fail[s] to meet the percentage standards
set forth in paragraph (a)," the rating agency may refer the case to the Compensation Service Director for consideration
of extraschedular TDIU. 38 C.F.R. § 4.16(b); see Cantrell v. Shulkin, 28 Vet.App. 382, 387 (2017).



                                                            3
evidence of record demonstrated that his service-connected PTSD and fibromyalgia collectively
rendered him unemployable. R. at 15. However, the Board denied extraschedular TDIU prior to
that date because, "[a]t that time, PTSD was [the veteran's] only service-connected disability, and
it was not of such severity as to render him unable to secure or maintain substantially gainful
employment." R. at 13. As relevant here, the Board explained that, although the March 2003 and
November 2005 VA examiners "opined that the [v]eteran's PTSD interfered with employment,"
they "did not state that his PTSD symptoms actually rendered him unable to obtain and maintain
substantially gainful employment." R. at 14. The Board also pointed out that the August 2008
VA examiner had "stated that the [v]eteran's PTSD symptoms, which were consistent with his
PTSD symptoms for the entire period on appeal up to that point, did not result in deficiencies at
work or total occupational and social impairment." Id. The Board therefore found that a
preponderance of the evidence was against awarding extraschedular TDIU based on service-
connected PTSD alone prior to October 11, 2006. Id. This appeal followed.


                                          II. ANALYSIS
                    A. TDIU Based on PTSD Alone Prior to October 11, 2006
                1. The Parties' Arguments & the Secretary's Concession of Error
       Mr. Delrio argues that the Board erred in denying entitlement to TDIU based on PTSD
alone prior to October 11, 2006, because it failed to articulate a clear standard for what constitutes
a substantially gainful occupation under § 4.16(b). Appellant's Brief (Br.) at 7-10; Reply Br. at
12-14. He also asserts that the Board provided inadequate reasons or bases for that portion of its
decision because, inter alia, it improperly characterized the March 2003 and November 2005 VA
examiners' silence as to whether the veteran was unemployable as evidence that he was, in fact,
employable; adopted the August 2008 VA examiner's negative opinion as its own without
reconciling that opinion with the other evidence of record or otherwise conducting an independent
analysis of whether PTSD precluded substantially gainful employment; and overlooked material
evidence that was potentially favorable to him. Appellant's Br. at 14-23; Reply Br. at 6-12.
       The Secretary initially disputed each of those contentions and urged the Court to affirm the
Board decision. Secretary's Br. at 14-27. However, shortly before oral argument, the Secretary
informed the Court that his position had changed and that he now concedes that the Board provided
inadequate reasons or bases for its decision because its TDIU analysis did not comply with the



                                                  4
Court's March 2019 decision in Ray v. Wilkie, 31 Vet.App. 58 (2019). Secretary's August 13,
2019, Notice to the Court. He asks the Court to vacate and remand the decision on appeal so that
the Board can readjudicate entitlement to TDIU prior to October 11, 2006, in accordance with Ray
and order any development it deems necessary in light of that precedent. Id. At oral argument,
the Secretary clarified that he is only conceding the Ray error and, although he generally contends
that the veteran's other reasons-or-bases arguments may require the Board to reassess the evidence
in accordance with Ray, he continues to oppose the veteran's arguments as a basis for remand.
Oral Argument (Arg.) at 40:16-41:42.
                                2. The Board's Failure to Comply with Ray
        The Court agrees with the Secretary that the Board's TDIU analysis does not comport with
Ray. In that case, the Court held that the phrase "unable to secure and follow a substantially gainful
occupation" in § 4.16 has economic and noneconomic components, the latter of which focuses on
the individual veteran's ability to perform the physical and mental acts necessary for such an
occupation. Ray, 31 Vet.App. at 73; see Van Hoose v. Brown, 4 Vet.App. 361, 363 (1993)
(clarifying that, for TDIU purposes, "[t]he question is whether the veteran is capable of performing
the physical and mental acts required by employment" (emphasis omitted)). The Court explained
that, for the Board to adequately address the noneconomic component of § 4.16, it must give
"attention" to factors that may affect the veteran's "mental ability to perform the activities required
by the occupation at issue," such as "the veteran's limitations, if any, concerning memory,
concentration, ability to adapt to change, handle work place stress, get along with coworkers, and
demonstrate reliability and productivity." Ray, 31 Vet.App. at 73 (citing Gleicher v. Derwinski,
2 Vet.App. 26, 28 (1991); Washington v. Derwinski, 1 Vet.App. 459, 465 (1991)). The Court
noted, however, that "discussion of any factor is only necessary if the evidence raises [its potential
applicability]." Id.
        The evidence of record in this case suggests that Mr. Delrio's service-connected PTSD
caused memory, concentration, and stress management issues that interfered with his ability to
work.3 See, e.g., R. at 2044-45 (former employer's April 1996 assessment that the veteran was

        3
          The Court acknowledges that the Board in part addressed this evidence, R. at 14, and that the veteran
challenges the adequacy of the Board's reasons or bases for affording minimal or no probative weight to the evidence,
Appellant's Br. at 15-19; Reply Br. at 11-12. However, as noted above, the Secretary concedes that the Board may
need to reevaluate the evidence to comply with Ray. Thus, the Court will not address each of the veteran's
reasons-or-bases arguments at this time. He is free to raise these specific arguments below and the Board is required



                                                         5
unable to engage in stress situations or interpersonal relations due to a "mental/nervous
impairment"), 2461 (former supervisor's November 1996 statement regarding the veteran's
declining work performance), 178-83 (November 1996 private psychiatric records describing the
veteran's social isolation, nonexistent interpersonal relationships, memory problems, and
diminished attention and concentration), 2330 (July 1997 SSA decision noting evidence of severe
depression, impaired judgment and insight, and a limited capacity to cope with stress, relate to
others, and persist in a task), 1959-60 (March 2003 VA psychiatric examination reflecting
complaints of memory problems, disorientation, confusion, depression, avoidant behavior, and
social isolation that "reduce[d] his employability"), 513 (veteran's August 2003 report that his last
employer "encouraged him to retire due to increased anger and irritability which affected his
work"), 438-39 (November 2005 VA psychiatric examiner's opinion that the veteran's PTSD
"interfere[d] with employment and social functioning due to his fear of friendship, anger,
depression[,] and asocial behavior" and that his PTSD caused an "inability to function in a social
as well as economic setting").
        Because Ray mandates that the Board discuss each of those limitations, when raised, in
order to adequately address the noneconomic component of TDIU, the Board's failure to do so in
this case renders inadequate its reasons or bases for denying TDIU based on PTSD alone prior to
October 11, 2006. See 31 Vet.App. at 73-74; Caluza v. Brown, 7 Vet.App. 498, 506 (1995)
(explaining that, to satisfy its statutory reasons-or-bases requirement, the Board must analyze the
credibility and probative value of evidence, account for evidence it finds persuasive or
unpersuasive, and provide reasons for its rejection of material evidence favorable to the claimant),
aff'd per curiam, 78 F.3d 604 (Fed. Cir. 1996) (table); Schafrath v. Derwinski, 1 Vet.App. 589,
592 (1991) (mandating that the Board discuss all provisions of law and regulation that are made
"potentially applicable through the assertions and issues raised in the record"). The Court therefore
accepts the Secretary's concession of error and will remand the case for the Board to issue a
decision that complies with Ray. See Tucker v. West, 11 Vet.App. 369, 374 (1998) (holding that
remand is the appropriate remedy "where the Board has incorrectly applied the law, failed to
provide an adequate statement of reasons or bases for its determinations, or where the record is
otherwise inadequate").


to consider them. See Kay v. Principi, 16 Vet.App. 529, 534 (2002) (stating that, on remand, the Board must consider
additional evidence and argument in assessing entitlement to the benefit sought).



                                                         6
                               3. Other Reasons-or-Bases Errors
       Although the Court has already determined that this case must be remanded to correct the
Ray error conceded by the Secretary, we are compelled to address three other reasons-or-bases
errors committed by the Board that, without our intervention, appear likely to recur on remand.
See Quirin v. Shinseki, 22 Vet.App. 390, 396 (2009) (holding that, to provide guidance to the
Board, the Court may address an appellant's other arguments after determining that remand is
warranted); see, e.g., McCray v. Wilkie, 31 Vet.App. 243, 258-59 (2019).
       First, the Board incorrectly characterized the March 2003 and November 2005 VA
examiners' silence as to Mr. Delrio's unemployability as evidence that his PTSD did not render
him unemployable. R. at 14. As the Court has previously explained, the absence of evidence on
a particular question cannot be construed as negative evidence against a claimant unless there is a
foundation in the record that demonstrates that such silence has a tendency to prove or disprove a
relevant fact. See Fountain v. McDonald, 27 Vet.App. 258, 272 (2015); Horn v. Shinseki,
25 Vet.App. 231, 239 n.7 (2012); Buczynski v. Shinseki, 24 Vet.App. 221, 224 (2011). The logic
underlying this rule is that silence in a given record only tends to prove nonoccurrence if "'the
records were kept in such a way that the matter would have been recorded had it occurred.'" AZ v.
Shinseki, 731 F.3d 1303, 1317 (Fed. Cir. 2013) (quoting 5 Jack B. Weinstein & Margaret A.
Berger, Weinstein's Federal Evidence § 803.09 (2d ed. 2012) (emphasis omitted)).
       Consequently, the foundation for drawing a negative inference from a record's silence is
ordinarily established by showing that "'a record was regularly kept' for the type of event in
question" or that it was "reasonable to expect the event to have been recorded." Id. at 1316-17
(quoting FED. R. EVID. 803(7), (10)(B)). Absent such a foundation, the absence of evidence
"provides neither positive nor negative support" for a claim because such silence does not
necessarily have the tendency to prove or disprove a relevant fact. Fagan v. Shinseki, 573 F.3d
1282, 1289 (Fed. Cir. 2009); see AZ, 731 F.3d at 1318 ("[W]here an alleged sexual assault . . . is
not reported, the absence of service records documenting the alleged assault is not pertinent
evidence that the assault did not occur."); Horn, 25 Vet.App. at 239 n.7 (concluding that the Board
erred in relying on a lack of service records documenting a medical condition because "there is no
evidentiary foundation, or even a logical reason to suppose," that the condition would have been
recorded during the veteran's treatment); Buczynski, 24 Vet.App. at 224 (holding that a doctor's
failure to assess the repugnance of a condition was "not a situation where the silence in regard to



                                                7
a condition can be taken as proof that a doctor did not observe the symptom" because there did
"not appear to be any medical reason why a doctor would be expected to comment on the
repugnance of a condition").
       Here, the Board found that the March 2003 and November 2005 VA examiners' opinions
weighed against an award of TDIU based on PTSD alone prior to October 11, 2006, because the
examiners opined only that the veteran's PTSD interfered with employment and "did not state that
his PTSD symptoms actually rendered him unable to obtain and maintain substantially gainful
employment." R. at 14. The Board did not, however, lay the necessary foundation for construing
the examiners' silence on that issue as substantive evidence against Mr. Delrio. Significantly, the
Board did not identify a section in either examination report that specifically addressed the
veteran's unemployability nor did the Board otherwise explain why it would have been reasonable
to expect that the examiners would have commented on that issue in examinations that were not
expressly provided for TDIU purposes. See AZ, 731 F.3d at 1316-17; Moore v. Nicholson,
21 Vet.App. 211, 219 (2007) (holding that, although "[t]he requirement that medical examiners
provide a report adequate for a rating decision will frequently require them to discuss . . . how the
disability manifests itself in the claimant's ordinary activities, which include employment," "it does
not require medical examiners to offer opinions on the general employability of a claimant"), rev'd
on other grounds sub nom. Moore v. Shinseki, 555 F.3d 1369 (Fed. Cir. 2009). Absent such an
evidentiary foundation, the examiners' silence would not have a tendency to prove whether the
veteran's PTSD rendered him unemployable, and the Board was therefore prohibited from
characterizing their silence on the issue as substantive evidence against entitlement to TDIU. See
AZ, 731 F.3d at 1318; Fagan, 573 F.3d at 1289; Horn, 25 Vet.App. at 239 n.7; Buczynski,
24 Vet.App. at 224. To the extent that the Board did just that, it erred.
       Second, the Board's assessment of the March 2003, November 2005, and August 2008 VA
medical examinations appears to be based, in part, on a misunderstanding of the distinct roles of
medical examiners and adjudicators in the veterans benefits system. Medical examiners are
"nothing more or less than expert witnesses" who provide opinions on medical matters. Nieves-
Rodriguez v. Peake, 22 Vet.App. 295, 302 (2008); see Gabrielson v. Brown, 7 Vet.App. 36, 40
(1994) (noting that a medical opinion is "only that, an opinion" providing medical evidence). Their
function is to provide VA adjudicators—who generally lack the expertise and competence to opine
on medical matters, see Kahana v. Shinseki, 24 Vet.App. 428, 438 (2011) (Lance, J., concurring);



                                                  8
Colvin v. Derwinski, 1 Vet.App. 171, 172 (1991), overruled on other grounds by Hodge v. West,
155 F.3d 1356 (Fed. Cir. 1998)—with the medical information and analysis necessary to decide a
claim. See 38 C.F.R. § 4.1 (2019) ("For the application of [the rating] schedule, accurate and fully
descriptive medical examinations are required. . . ."); 38 C.F.R. § 4.10 (2019) (assigning to medical
examiners "the responsibility of furnishing . . . full description of the effects of disability upon the
person's ordinary activity"). It is the responsibility of VA adjudicators, not medical examiners, to
make the findings of fact and law necessary to decide a claimant's entitlement to disability benefits.
See Withers v. Wilkie, 30 Vet.App. 139, 146 (2018) ("[E]xaminers provide evidence; they are not
permitted to opine on legal or adjudicative matters."); Moore, 21 Vet.App. at 218 ("The medical
examiner provides a disability evaluation and the rating specialist interprets medical reports in
order to match the rating with the disability."); 38 C.F.R. § 3.100(a) (2019) (delegating the
Secretary's authority "to make findings and decisions . . . as to entitlement of claimants to benefits"
to, inter alia, VA "adjudicative personnel"); 38 C.F.R. § 4.2 (2019) ("It is the responsibility of the
rating specialist to interpret reports of examination . . . so that the current rating may accurately
reflect the elements of disability present."). Given this division of responsibilities, the Board errs
when it relies on a medical examiner's opinion on a purely adjudicative matter. See, e.g., D'Aries
v. Peake, 22 Vet.App. 97, 106 (2008) (per curiam) ("[T]he benefit of the doubt doctrine is a legal
construct to be applied by an adjudicatory body . . . , not by a medical professional when rendering
an opinion."); Moore, 21 Vet.App. at 218 (noting that it is the duty of VA adjudicators, not medical
examiners, to apply the appropriate legal standard); Sizemore v. Principi, 18 Vet.App. 264, 275
(2004) (faulting a VA examiner for "expressing an opinion on whether the appellant's claimed in-
service stressors have been substantiated, [which] is a matter for determination by the Board and
not a medical matter").
        In the context of TDIU, "applicable regulations place responsibility for the ultimate TDIU
determination on the VA, not a medical examiner." Geib v. Shinseki, 733 F.3d 1350, 1354 (Fed.
Cir. 2013). Specifically, "TDIU is to be awarded based on the 'judgment of the rating agency' that
the veteran is 'unable to secure or follow a substantially gainful occupation as a result of service-
connected disabilities.'" Floore v. Shinseki, 26 Vet.App. 376, 381 (2013) (quoting 38 C.F.R.
§ 4.16(a)). That determination is not medical in nature, and it is not the province of medical
examiners to opine on whether a veteran's service-connected disabilities preclude substantially
gainful employment. See Geib, 733 F.3d at 1354; Floore, 26 Vet.App. at 381; see generally Ray,



                                                   9
31 Vet.App. at 71-74 (detailing the economic and noneconomic components of the substantially-
gainful-employment inquiry). Of course, medical examiners may assist VA adjudicators in
making that determination by providing detailed descriptions of the veteran's disabilities and any
functional limitations that they cause. See Withers, 30 Vet.App. at 142. But the authority to make
the ultimate determination of whether a veteran meets the § 4.16 standards for TDIU belongs
exclusively to the VA adjudicator and may not be delegated out to one of the agency's medical
examiners. See Geib, 733 F.3d at 1354; Floore, 26 Vet.App. at 381.
       With this framework in mind, we return to the decision currently on appeal. As noted
above, the Board found that the March 2003 and November 2005 VA examinations weighed
against entitlement to TDIU based on PTSD alone prior to October 11, 2006, because the
examiners "did not state that [the veteran's] PTSD symptoms actually rendered him unable to
obtain and maintain substantially gainful employment." R. at 14. Although neither examiner
actually opined on that adjudicative issue, see R. at 437-39, 1959-61, the Board's apparent
expectation that they would evinces a misunderstanding of the distinctive responsibilities of
medical examiners and adjudicative personnel and demonstrates that the Board misapplied the law
for determining whether the veteran's PTSD rendered him unable to secure and follow a
substantially gainful occupation. See Geib, 733 F.3d at 1354; Floore, 26 Vet.App. at 381.
       Similarly, to the extent that the Board found that the August 2008 VA medical examination
weighed against an award of TDIU based on PTSD alone prior to October 11, 2006, because the
examiner opined that the veteran did not meet the schedular criteria for a 100% evaluation for
PTSD, R. at 14, the Board erred in equating the examiner's finding that the veteran's PTSD did not
cause total occupational and social impairment with an inability to obtain and maintain
substantially gainful employment. See Roberson v. Principi, 251 F.3d 1378, 1385 (Fed. Cir. 2001)
("Requiring a veteran to prove that he is 100[%] unemployable is different than requiring the
veteran to prove that he cannot maintain substantially gainful employment."). Although the Board
should consider an examiner's findings regarding the manner and extent to which a veteran's PTSD
symptoms affect his or her ability to work when deciding entitlement to TDIU, see Withers,
30 Vet.App. at 142, the Board cannot uncritically adopt an examiner's assessment of the veteran's
level of disability as its own without reconciling that assessment with the other evidence of record,
see Gabrielson, 7 Vet.App. at 40. Nor can the Board outsource to a medical examiner its
independent responsibility to make an adjudicative determination as to entitlement to a claimed



                                                 10
disability evaluation, including TDIU. See Geib, 733 F.3d at 1354; Withers, 30 Vet.App. at 146;
Floore, 26 Vet.App. at 381; Moore, 21 Vet.App. at 218. The Board committed both of those errors
here when it summarily concluded that the August 2008 VA medical examination weighed against
entitlement to TDIU based solely on the examiner's conclusion that the veteran's PTSD did not
warrant a 100% evaluation. R. at 14.
       Finally, the Board did not address material evidence that was potentially favorable to Mr.
Delrio's entitlement to TDIU, including his August 2003 report to a VA social worker that his
former employer "encouraged him to retire due to increased anger and irritability which affected
his work." R. at 513. Because that evidence tends to support his assertions that PTSD rendered
him unable to secure and follow a substantially gainful occupation prior to October 11, 2006, the
Board was obligated to address it. See Caluza, 7 Vet.App. at 506. The Board's failure to do so
further justifies remand. See Tucker, 11 Vet.App. at 374.
                  B. Consideration of Fibromyalgia Prior to October 11, 2006
       The foregoing disposition does not, however, resolve the question of whether the Board on
remand is required to address Mr. Delrio's fibromyalgia when deciding whether he is entitled to
TDIU prior to October 11, 2006. For the following reasons, we conclude that the Board need not
do so because the veteran was not service connected for fibromyalgia prior to that date.
                                   1. The Parties' Arguments
       Mr. Delrio primarily argues that the Board erred in not considering the effects of his
service-connected fibromyalgia when assessing his entitlement to TDIU before October 11, 2006,
because, once VA determined that his fibromyalgia was related to service, the effective date for
the grant of service connection for that condition became "irrelevant" and the only issue left to
resolve was "whether the symptoms of that now-recognized service-connected disability
contributed to [his] inability to engage in substantially gainful employment." Appellant's Br. at
12; see Reply Br. at 1. He asserts that he was prejudiced by the Board's failure to consider his
fibromyalgia symptoms prior to October 11, 2006, because the record reflects that he was first
diagnosed with fibromyalgia in 1991 and that the widespread pain he has experienced since service
contributed to his unemployability, warranting an earlier effective date for TDIU based on the
combined effects of his PTSD and fibromyalgia. Appellant's Br. at 13-14.
       The veteran's argument is premised on Frost v. Shulkin, 29 Vet.App. 131, 138 (2017),
where the Court held that 38 C.F.R. § 3.310—a secondary service connection regulation with some



                                               11
language similar to § 4.16—did not contain an express temporal requirement and therefore did not
preclude a grant of secondary service connection for a disability based on a primary disability that
was service connected at the time of the secondary service connection decision but not at the time
of incurrence of the secondary disability. Appellant's Br. at 10-12; Reply Br. at 1-6. He
extrapolates from Frost that, so long as a disability is service connected at the time that VA decides
entitlement to TDIU based in part on that disability, § 4.16's lack of an express temporal
requirement allows VA to consider the effects of that disability on unemployability throughout the
TDIU period on appeal, regardless of the effective date of service connection for the disability.
Appellant's Br. at 12; Reply Br. at 4.
         Mr. Delrio's argument also relies on the unique characteristics of TDIU and the fact that
§ 4.16(a) refers to "ratable," rather than "rated," service-connected disabilities.4 In his view, these
features of § 4.16 mean that a disability need only be service connectable, not service connected,
to be considered in the TDIU effective date inquiry. Appellant's Br. at 11-12 (arguing that the
term "ratable" "encompasses the possibility of a rating[] and does not demand an established one");
Oral Arg. at 7:16-:57; see Reply Br. at 2-4. As specific support for this proposition, he points to
Gazelle v. Shulkin, 868 F.3d 1006, 1011 (Fed. Cir. 2017), where the U.S. Court of Appeals for the
Federal Circuit (Federal Circuit) held that "ratable" in a special monthly compensation (SMC)
statute means "capable of being rated or estimated," as opposed to actually rated. Reply Br. at 2-
4 (emphasis added).
         The Secretary responds that Frost is distinguishable from the instant case because it
involved secondary service connection under § 3.310 and not TDIU under § 4.16. Secretary's Br.
at 11-14. He argues that TDIU, unlike secondary service connection, is "premised on a specific



         4
           The Court notes that, although Mr. Delrio's argument focuses on the language in 38 C.F.R. § 4.16(a), he is
seeking entitlement to TDIU pursuant to 38 C.F.R. § 4.16(b). Section 4.16(b) does not contain the word "ratable" or
the corresponding instructions for tabulating disability evaluations for TDIU purposes, see Youngblood, 31 Vet.App.
at 417, but that portion of § 4.16(a) is expressly incorporated into § 4.16(b) by reference and § 4.16(b), by its terms,
applies to "all veterans who are unable to secure and follow a substantially gainful occupation by reason of service-
connected disabilities," 38 C.F.R. § 4.16(b) (specifying that paragraph (b) applies to all cases of individuals "who fail
to meet the percentage standards set forth in paragraph (a) of this section"); see Cantrell, 28 Vet.App. at 388 n.5
(noting that "[a]lthough the term 'marginal employment' appears only in § 4.16(a), there is nothing in the regulation
to suggest, nor has the Secretary asserted, that VA is precluded from determining that marginal employment exists for
purposes of referring a case for consideration of extraschedular TDIU under § 4.16(b)"); see generally Vazquez–
Claudio v. Shinseki, 713 F.3d 112, 115 (Fed. Cir. 2013) ("In construing regulatory language, we must read the disputed
language in the context of the entire regulation as well as other related regulatory sections in order to determine the
language's plain meaning.").

period of time" and a determination as to a TDIU effective date expressly excludes consideration
of disabilities that are not service connected during that specific period. Id. at 12-13.
          2. The Effective Date for TDIU Cannot be Earlier than the Effective Date of
               Service Connection for the Underlying Disability or Disabilities
       Interpretation of a regulation is a legal question that the Court reviews de novo. See Moody
v. Wilkie, 30 Vet.App. 329, 336 (2018) (per curiam).
       We begin our analysis of the parties' dispute from the well-settled position that TDIU is, at
bottom, an evaluation for a service-connected disability or disabilities. See Rice v. Shinseki,
22 Vet.App. 447, 453 (2009) (per curiam) (holding that "a request for TDIU . . . is not a separate
claim for benefits, but rather involves an attempt to obtain an appropriate rating for a disability or
disabilities"). Section 4.16, like other evaluation regulations in part 4 of title 38 of the Code of
Federal Regulations, specifies the criteria that must be met to be entitled to disability compensation
payment at a given rate. Inherent in each of those evaluation regulations, and the statutes that
authorize payment of disability compensation in general, see 38 U.S.C. §§ 1110, 1131, is the
requirement that the disability being evaluated has been determined to be service connected. See
Grantham v. Brown, 114 F.3d 1156, 1158-59 (Fed. Cir. 1997) (characterizing evaluation of a
disability as a downstream issue from service connection of the disability); 38 C.F.R. pt. 4 (entitled
Schedule for Rating Disabilities).       This base temporal requirement in part 4 means that
compensation cannot be paid for a disability, at any evaluation level, before the effective date of
service connection for the disability.
       Mr. Delrio asks us to carve out an exception from this general compensation payment rule
for TDIU, but neither § 4.16's unique characteristics nor its linguistic similarities to the regulation
at issue in Frost justify such an exception. As to the veteran's first contention, the Court agrees
that TDIU is sui generis insofar as it is the only disability evaluation that (1) is based on an
individual's particular circumstances rather than average impairment in earning capacity, see
Pederson v. McDonald, 27 Vet.App. 276, 286 (2015) (en banc) (citing Rice, 22 Vet.App. at 452);
see also 38 C.F.R. § 4.1; and (2) may take into account the cumulative effect of multiple service-
connected disabilities, see Geib, 733 F.3d at 1354 (citing 38 C.F.R. §§ 4.15, 4.16). See Oral Arg.
at 6:43-7:15. But those peculiarities do not overcome the plain language of § 4.16, which expressly
directs that "the existence or degree of nonservice-connected disabilities . . . will be disregarded"
when determining entitlement to TDIU. 38 C.F.R. § 4.16(a); see Van Hoose, 4 Vet.App. at 363
(emphasizing that, when deciding entitlement to TDIU, the "Board's task [is] to determine whether


                                                  13
there are circumstances . . . apart from the non-service-connected conditions and advancing age
which would justify [TDIU]" (emphasis omitted)); Pratt v. Derwinski, 3 Vet.App. 269, 272 (1992)
(holding that the Board "was required to decide, without regard to the non-service-connected
disabilities or his age, whether appellant's service-connected disabilities are sufficiently
incapacitating as to render [the veteran] unemployable"); see also Pacheco v. Gibson, 27 Vet.App.
21, 25 (2014) (en banc) ("If the meaning of [a regulation] is clear from its plain language, that
meaning controls and that is the end of the matter."). Prior to October 11, 2006, fibromyalgia was
a non-service-connected disability, and the Board was therefore required to disregard its effects
when determining whether the veteran's service-connected disabilities precluded substantially
gainful employment.
        Mr. Delrio seeks to avoid this conclusion by arguing that § 4.16(a)'s requirement that a
disability or disabilities be "ratable," rather than "rated," at specified disability levels means that a
disability need not be service connected for the entire period for which TDIU is sought to be
factored into the substantially gainful employment analysis. Appellant's Br. at 11-12; Reply Br.
at 2-4; Oral Arg. at 7:16-:57. But this argument reads too much into the term "ratable."
        As noted above, supra note 2, one of the requirements for an award of TDIU under
§ 4.16(a) is a single disability "ratable at 60[%] or more" or one disability "ratable at 40[%] or
more, and sufficient additional disability to bring the combined rating to 70[%] or more."
38 C.F.R. § 4.16(a). Although Mr. Delrio is correct that the Federal Circuit in Gazelle held that
"ratable" in 38 U.S.C. § 1114(s)—a statute authorizing the payment of SMC where a veteran has
"a service-connected disability rated as total" and, as relevant here, "additional service-connected
disability or disabilities independently ratable at 60[%] or more"—means "'capable of being rated
or estimated,'" 868 F.3d at 1011 (quoting WEBSTER'S THIRD NEW INTERNATIONAL DICTIONARY
VOLUME II, 1884 (1986)), he overlooks that the Federal Circuit qualified that definition by holding
that a disability or disabilities is only "ratable" at a given level if rated at or above that level
individually or through application of the combined ratings table in 38 C.F.R. § 4.25(b), id. at
1011-12. Applying that considerably narrower definition of "ratable" to the facts of Gazelle, the
Federal Circuit held that section 1114(s) "unambiguously requires the veteran's additional
disabilities be rated at least at [60%] based upon the combined ratings table and not the addition
of individual disability ratings," as the veteran had argued. Id. at 1012 (emphasis added) (emphasis




                                                   14
omitted). One year later, the Court expressly adopted and applied the Federal Circuit's reasoning
in Gazelle, including the definition of "ratable," to § 4.16(a). Moody, 30 Vet.App. at 335-39.
       Gazelle and Moody directly refute Mr. Delrio's construction of "ratable" in § 4.16(a).
Consistent with those cases, TDIU may only be awarded under § 4.16(a) if the veteran has either
(1) one disability "ratable" at 60% or more—i.e., a single disability evaluated as at least 60%
disabling or multiple disabilities treated as "one disability" for TDIU purposes that can be
combined via § 4.25(b) to reach at least 60%; or (2) one disability "ratable at 40[%] or more"—
i.e., a single disability evaluated as at least 40% disabling or multiple disabilities treated as "one
disability" for TDIU purposes that can be combined via § 4.25(b) to reach at least 40%—with
"sufficient additional disability to bring the combined rating to 70[%] or more." 38 C.F.R.
§ 4.16(a). This definition of "ratable" accords not only with our prior observation that "ratable"
and "rated" have different meanings in the VA benefits context, see Gazelle v. McDonald,
27 Vet.App. 461, 467 (2016), aff'd sub nom. Gazelle v. Shulkin, 868 F.3d 1006 (Fed. Cir. 2017),
but also with part 4's base temporal requirement and § 4.16(a)'s prohibition against considering
non-service-connected disabilities in the TDIU inquiry.
       Contrary to Mr. Delrio's contentions, Frost does not compel a different outcome. The issue
in Frost was "whether a veteran [was] precluded, as a matter of law, from obtaining secondary
service connection on a causation basis when the secondary condition was incurred prior to the
grant of service connection for, or diagnosis of, the primary condition." 29 Vet.App. at 134. The
Court held that secondary service connection was available in that situation because § 3.310(a)
does not contain an express temporal requirement and any such requirement would make "little
sense" given the "protracted nature of veterans benefits claims adjudication" and the fact that "a
veteran has no obligation to file a [disability] compensation claim as soon as he or she becomes
aware of [a] disability." Id. at 137-38. Instead, the Court indicated that the only temporal
requirement affiliated with § 3.310(a) "is one of basic logic that the Court has referenced in
previous cases, i.e., that 'there must be a primary service-connected condition for a claimant to
establish entitlement to secondary service connection'"; in other words, "at the time that any
decision establishing entitlement to secondary service connection is rendered, there must be a
primary service-connected condition." Id. at 138 (emphasis omitted) (quoting Smith v. Shinseki,
24 Vet.App. 40, 49 (2010)).




                                                 15
       The essential difference between Frost and this case is that Frost involved § 3.310, a
secondary service connection regulation, whereas Mr. Delrio's appeal involves § 4.16, a disability
evaluation regulation that prescribes a compensation payment rule. This distinction is critical
because, unlike § 3.310, § 4.16 contains the additional base temporal requirement and limit on
consideration of non-service-connected disabilities discussed above. Because entitlement to TDIU
under § 4.16 is subject to these additional "temporal prerequisites," it is fundamentally different
from § 3.310, which was temporally limited only by the requirement that a veteran have a service-
connected disability when entitlement to secondary service connection is decided.                Frost,
29 Vet.App. at 138. Mr. Delrio's arguments based on Frost therefore fail.
       To be clear, the lesson of Frost is not that benefits may be awarded independent of the
effective date of service connection for an underlying disability, as the veteran asserts. Rather,
Frost is limited to its facts and stands for the proposition that, to later support a grant of secondary
service connection, a primary disability need not be service connected or even diagnosed at the
time that a secondary disability is incurred. 29 Vet.App. at 138. Frost is concerned with causation
for secondary service connection purposes; it does not permit or require VA to ignore the effective
date of a grant of service connection when assigning an evaluation based on that service-connected
disability. As such, Frost is inapposite and the veteran's reliance on it is misplaced.
       Accordingly, the Court holds that the effective date of TDIU cannot be earlier than the
effective date of the award of service connection for the disability or disabilities upon which the
award of TDIU is based. To hold otherwise would create the absurd result that a veteran could be
paid compensation at the total disability rate under § 4.16 for a disability prior to the date that a
grant of service connection became effective. As the Court has recognized in prior cases, albeit
without a full analysis, that simply cannot be the case. See Ross v. Peake, 21 Vet.App. 528, 534
(2008) (concluding that the effective date for a schedular award of TDIU based on service-
connected depression with anxiety could not "be earlier than the date of [the veteran's] claim for
secondary service connection for [those conditions]"), aff'd per curiam sub nom. Ross v. Shinseki,
309 F. App'x 394 (Fed. Cir. 2009); Canady v. Nicholson, 20 Vet.App. 393, 398 (2006) (explaining
that, "as a matter of law, the assignment of a [schedular] TDIU rating could not be effective earlier
than the effective date of his award of service connection" for the underlying disability).
Consequently, the Court concludes that, on remand, the Board need not address the effects of the




                                                  16
veteran's fibromyalgia on his ability to secure and follow a substantially gainful occupation prior
to October 11, 2006.
       Mr. Delrio is free on remand, however, to present to the Board any additional arguments
and evidence pertinent to his entitlement to TDIU based on PTSD alone prior to that date. See
Kay, 16 Vet.App. at 534; Kutscherousky v. West, 12 Vet.App. 369, 372-73 (1999) (per curiam
order). The Court reminds the Board that "[a] remand is meant to entail a critical examination of
the justification for [the Board's] decision," Fletcher v. Derwinski, 1 Vet.App. 394, 397 (1991),
and must be performed in an expeditious manner in accordance with 38 U.S.C. § 7112.


                                      III. CONCLUSION
       Upon consideration of the foregoing, the portion of the September 19, 2017, Board decision
denying entitlement to TDIU based on PTSD alone prior to October 11, 2006, is SET ASIDE and
that matter is REMANDED for further development, if necessary, and readjudication consistent
with this decision. The remainder of the Board decision is AFFIRMED.
