         Before GREENBERG, TOTH, and FALVEY, Judges.

         FALVEY, Judge: The appellant, Llewellyn R. Miller, through counsel appeals a May 7,
2018, Board of Veterans' Appeals (Board) decision that denied service connection for a bilateral
foot disability and gastroesophageal reflux disease (GERD), both including as secondary to a
service-connected disability, and that denied service connection for chronic fatigue syndrome,
including as caused by an undiagnosed illness. 1 Mr. Miller's appeal is timely and within our
jurisdiction.2
         This matter was submitted to a panel of this Court, with oral argument, to address the proper
remedy when a VA medical examiner fails to address the veteran's reports of his medical history

           Record (R.) at 2-20; The Board also denied service connection for right ear hearing loss, remanded a claim
for service connection for a low back disability, and granted service connection for left ear hearing loss. Because Mr.
Miller makes no arguments about these issues, see Pederson v. McDonald, 

, 283 (2015) (en banc)
("this Court, like other courts, will generally decline to exercise its authority to address an issue not raised by an
appellant in his or her opening brief"), and we are without jurisdiction to address the remand, see Breeden v. Principi,

, 478 (2004) (a Board remand "does not represent a final decision over which this Court has
jurisdiction"), or disturb the grant of benefits, see Medrano v. Nicholson, 

, 170-71, (2007) (noting
that Court is not permitted to reverse Board's favorable findings of fact), the Court will not address these matters on
appeal.

and symptoms and the Board does not address the credibility of those statements or otherwise find
the veteran not credible. Because we presume that the Board reviewed all relevant evidence and
we may review its implicit findings of fact, including implicit credibility determinations, we hold
that when the examiner fails to address the veteran's lay evidence, and the Board fails to find the
veteran not credible or not competent to offer that lay evidence, the proper remedy is for VA to
obtain a new examination.


                                             I. BACKGROUND
        Ordinarily, we would describe the content of a veteran's statements or other evidence—
such as medical examinations—in detail. But because this matter deals with the proper remedy for
when an examiner skips over those statements, the substance of the statements or the exam is not
all that relevant to our analysis. It is not what the exams address but what they omit that brings us
here. Thus, we focus only on the facts needed to understand how we got here and where Mr.
Miller's case will be going.
        Mr. Miller served on active duty in the Navy from June 1988 to July 1994.3 In April 2011,
he sought service connection for stiffness in his joints, fatigue, and stomach illness, asserting that
these disabilities began in 1993 while he was still in service.4 In September 2011, he provided
more details about his symptoms. 5 He explained when he began experiencing heartburn and
indigestion and how he first treated these and other symptoms, including foot problems, with over-
the-counter medications. He also asserted that many of his symptoms were caused by his service
during the Persian Gulf War.6
        Thus, in April 2012, a VA examiner evaluated Mr. Miller using the "Gulf War General
Medical Examination Disability Benefits Questionnaire" (April 2012 exam) used by VA for claims
related to the presumptions available to veterans with qualifying Persian Gulf War service. 7
Following this examination, the regional office (RO) denied his GERD and fatigue claims in a

at 1434-1510; see also 38 U.S.C § 1117 (establishing presumptions for veterans with qualifying Persian
Gulf War service).

June 2012 rating decision.8 Mr. Miller responded in June 2012 with a Notice of Disagreement and
by filing a new claim for a bilateral foot disability.9 And the RO also denied his claim for a bilateral
foot disability.10
          Eventually, Mr. Miller's claims made it to the Board for the first time. Along the way, he
submitted various statements describing the symptoms of his disabilities.11 In December 2016, the
Board remanded his foot, GERD, and fatigue claims, 12 leading to a gastrointestinal (GI)
examination to address GERD and another medical examination to address his foot claim, both in
March 2017.13
          In addressing GERD, the examiner opined that this disability was unrelated to service
because Mr. Miller's in-service GI symptoms had resolved and he was not evaluated for additional
GI issues until 2009. As for the bilateral foot disability, the examiner explained that it was
unrelated to service because it did not bother him in service. In both opinions, it is inescapable that
the examiner did not acknowledge Mr. Miller's statements that he has had foot pain and GI issues
since service and that he self-medicated for both problems while in service.
          After the March 2017 examinations, Mr. Miller's claims returned to the Board, leading to
the decision here on appeal. In that decision, the Board found that VA had satisfied its duty to
assist in part, because the VA medical examinations were adequate. Mr. Miller disagrees. He asks
us to find all three examinations inadequate and to reverse the Board's finding that VA had satisfied
its duty to assist.

                                                   A. Legal Landscape
          Before we set out to consider whether Mr. Miller seeks the appropriate relief, we will
review what makes an examination adequate and how the Secretary's duty to assist comes into
play. The Secretary has a duty to assist claimants in obtaining evidence necessary to

                                                               3
their claim for a benefit.14 Part of this duty to assist requires that the Secretary provide a medical
examination or obtain a medical opinion "when such an examination or opinion is necessary to
make a decision on the claim."15 And once the Secretary seeks to provide an examination, he must
provide an adequate one or, at a minimum, tell the claimant why one cannot be provided.16
        As for our review, the adequacy of a medical examination is a finding of fact that we review
under the "clearly erroneous" standard.17 "A finding is 'clearly erroneous' when although there is
evidence to support it, the reviewing court on the entire evidence is left with the definite and firm
conviction that a mistake has been committed."18 And "[a]n opinion is adequate where it is based
upon consideration of the veteran's prior medical history and examinations and also describes the
disability in sufficient detail so that the Board's evaluation of the claimed disability will be a fully
informed one."19
        The bottom line is that "VA medical examiners and private physicians offering medical
opinions in veterans benefits cases are nothing more or less than expert witnesses."20 Thus, their
opinions "are adequate when they sufficiently inform the Board of a medical expert's judgment on
a medical question and the essential rationale for that opinion." 21 This includes addressing a
veteran's reports of symptoms and medical history.
        One of our frequently cited cases for this requirement is Barr v. Nicholson.22 In that case,
the Board denied service connection for varicose veins because it found that the veteran was not
competent to report that his varicose veins had started in service.23 We held that the Board erred

and explained why a lay individual could report the onset of varicose veins.24 But we were not
done.
         We also addressed the adequacy of a medical examination that the Board relied on to deny
that appellant's claim. We found the examination inadequate because the examiner could not
access the claimant's medical records and "did not indicate whether he considered Mr. Barr's
assertions of continued symptomatology." 25 Despite finding the examination inadequate, we
remanded the case to the Board for it to make credibility determinations about the appellant's
assertions of his continued varicose vein symptomology. 26 As we noted, credibility was a
determination the Board would have reached only after finding the veteran competent to report his
symptoms—something it did not do because it erroneously found him not competent to report
varicose veins.27 Further, the credibility determination was particularly warranted in Barr because,
if his statements were credible, the veteran may have been entitled to service connection under 38
C.F.R. § 3.303(b)—a presumptive theory of service connection.28 Despite remanding for the Board
to address credibility, Barr also tied the adequacy of an examination to whether the examiner
considers a veteran's reports of symptoms.29
         We relied on this part of Barr in McKinney v. McDonald to find a hearing loss examination
inadequate. 30 In McKinney, besides other claims, VA denied the appellant service connection for
bilateral hearing loss.31 Like in Barr, the main question for the Court was not the adequacy of a
medical examination. Instead, the focus was on whether hearing loss noted upon entry qualified as
a preexisting disability under 38 U.S.C. § 1111.32 After finding that the Board erred in concluding

("Once evidence is determined to be competent, the Board must determine whether such evidence
is also credible.").
         28
           Since then, the Federal Circuit has clarified that § 3.303(b) applies only to the chronic diseases enumerated
in 38 C.F.R. §3.309(a), thus making it inapplicable to varicose veins and limiting parts of Barr. Walker v. Shinseki,

that the veteran was not entitled to the presumption of soundness and reversing that determination,
we turned to the hearing loss examination.
       We found that examination inadequate for two reasons. First, the examiner failed to provide
an adequate rationale for why she would have to resort to speculation to render a nexus opinion;
and second, the examiner failed to consider the veteran's testimony when formulating her
opinion.33 In recounting the testimony, we noted that "[t]he Board did not make a finding that this
testimony was not credible." 34 And then, relying on Barr for its "finding that a medical
examination that ignores lay assertions regarding continued symptomatology is inadequate
because it fails to take into account the veteran's prior medical history," we held that the
examination in McKinney was likewise inadequate.35 But, instead of remanding to the Board for a
credibility determination, we ordered that the Board obtain a new medical examination.36 This
different remedy gives us the dispute at hand.
                                           B. The Parties' Arguments
       Although Mr. Miller and the Secretary agree that this matter must be remanded, they don't
agree about why. The Secretary says that we should remand because the Board failed to determine
Mr. Miller's credibility and to address his lay statements. Mr. Miller says that it wasn't the Board
that failed to address his statements, but the VA examiners. He points out that neither the March
2017 foot examination nor the March 2017 GI examination addresses his reports of symptoms.
Thus, he argues that, rather than let the Board discuss his credibility, we should reverse its finding
that VA satisfied its duty to assist because VA provided inadequate medical examinations and
order new medical examinations.
       In the end, the Secretary does not dispute that the examinations fail to address testimony
from the veteran. That the examinations are inadequate given the veteran's reports is not a
contentious issue here. Thus, our opinion does not dissect the legal considerations involved in
determining whether an examiner appropriately considered a veteran's statements. Instead, the
dispute here is about the remedy—do we remand for credibility-related reasons or bases or do we

reverse and remand for new examinations? To answer this question, we must resolve which of our
cases is controlling here, McKinney v. McDonald37 or Barr v. Nicholson.38
       This is because the Secretary's argument—that we should remand for a credibility
determination—finds support in Barr, while Mr. Miller's—that we should reverse the duty to assist
determination and remand for new examinations—finds support in McKinney. And so, this is how
the remedy dispute arises. We have two precedential decisions that, at first blush, appear to support
different results. To aid our resolution of this case, we asked the parties to provide supplemental
briefing addressing whether there is a conflict between these two cases. Although the parties agree
that the two can be reconciled, they remain at odds about the result of this case.
       The Secretary argues that the Court should remand for the Board to make an initial
credibility determination. Essentially, the Secretary tries to get the same result as in Barr. He
makes the case that the Board needs to determine whether Mr. Miller is credible before VA gives
him an examination. He also advocates for a narrow reading of McKinney, one that focuses on our
determination that the examination for hearing loss was inadequate because the examiner failed to
explain why she would have to resort to speculation to offer a nexus opinion. Finally, he explains
that there is no support for the Court to conclude that the Board made an implicit credibility
determination and that remanding for a new examination where the Board is silent about credibility
would lead to wasted resources, because the examinations would be unnecessary if the Board first
finds the veteran not credible.
       On the other hand, Mr. Miller maintains, as he did in his opening brief, that McKinney is
controlling here. He argues that McKinney should be read as holding that an examination is
inadequate if the examiner fails to consider the veteran's reports of symptoms and that the Court
does not need to remand for a credibility determination if there is no indication that the Board
found the veteran not credible. Instead, he argues that we may conclude that the Board found the
veteran credible, because we presume that the Board reviewed all the evidence but, at the same
time, we require that the Board discuss only the relevant evidence. Thus, he reasons that the Board
would only be obliged to offer an explanation if it did not find a claimant credible. He further
points out that the Secretary's argument—that the Board must first determine credibility—flips the



       37

                                                 7
system on its head. After all, veterans are examined before they get to the Board. Thus, the duties
of the examiner or the adequacy of the examination cannot be controlled by what the Board
determines about the veteran's credibility down the line. And, he also asks us to consider that an
examiner's opinion about the plausibility of lay contentions could inform the Board's credibility
determination, thus further supporting his argument that a new examination should be ordered
before the Board tackles credibility.
                                                 C. Barr and McKinney
         With strikingly different views of the law, we start our analysis where we find common
ground. There is no question that adequately informing the Board of the veteran's disability while
considering prior medical history requires addressing the veteran's lay reports of
symptomatology. 39 Thus, a "VA examiner's failure to consider [the veteran's] testimony when
formulating her opinion renders that opinion inadequate."40 This is something that both Barr and
McKinney agree on—an examination is inadequate if the medical professional fails to consider the
veteran's own lay reports of symptoms.
         That said, the Secretary is mistaken when he reads Barr to hold that we must remand for
the Board to address the credibility of the veteran's testimony every time the examiner fails to
address that testimony in an examination. The central issue in Barr was whether the veteran was
competent to report that he had varicose veins. Because the Board found he was not competent, it
did not reach the issue of his credibility. This is because, it is only "once evidence is determined
to be competent, [that] the Board must determine whether such evidence is also credible."41 And
so, when the Board erroneously determined that the veteran was not competent to report his
symptoms, it stopped considering the credibility or weight of that evidence. Thus, we remanded
for the Board to complete its credibility determination as it related to the Board's analysis of
presumptive service connection and remanded for VA to provide a new and adequate examination
that considered the veteran's lay statements about his continued symptomatology or to explain why
it would not provide one.

; citing Layno v. Brown, 

(1994) ("Competency, however,
must be distinguished from weight and credibility. The former is a legal concept determining whether testimony may
be heard and considered by the trier of fact, while the latter is a factual determination going to the probative value of
the evidence to be made after the evidence has been admitted.").



                                                           8
       By contrast, in McKinney, nothing stopped the Board from reaching credibility.42 Thus,
when we found that the examiner did not consider the veteran's reports of his hearing symptoms,
we ordered a new examination.43 There was nothing for the Board to do about the veteran's reports.
       The Secretary argues that the only prejudicial error in that part of McKinney was that the
Board relied on an opinion where the examiner failed to explain why she could not offer a
definitive nexus opinion. However, this argument does not hold up with what we said in McKinney.
       Indeed, we discussed both the examiner's failure to explain why she could not give her
opinion without resorting to mere speculation and, cited Barr and other relevant case law, to
conclude that "the VA examiner's failure to consider Mr. McKinney's testimony when formulating
her opinion renders that opinion inadequate." 44 In the end, we concluded that "because the
examiner did not provide a clear rationale for her opinion or consider relevant evidence in
formulating her opinion, the Court holds that the Board erred in relying on that opinion to deny
Mr. McKinney's claim."45
       Thus, it is simply not true that McKinney led to a new opinion only because of a lack of
rationale.46 Instead, either reason—lack of rationale or failure to consider relevant evidence—
supported a new medical opinion. And so, we read Barr and McKinney to say that an examiner
must address the veteran's relevant statements and, if the examiner fails to address the veteran’s
reports of his or her medical history and the Board is silent about the credibility of the veteran’s
lay statements, the Court will order a new examination absent an indication that the Board did not
reach credibility. This means that when we review a Board decision reliant on a medical opinion
that does not address the veteran's own reports of symptoms, we will order a new examination if
the Board never impugned the veteran's credibility.
       This dovetails with our musculoskeletal rating precedent. For example, in Sharp v. Shulkin
we ordered a new examination based on the examiner's failure to adequately elicit evidence about
the frequency, severity, duration, or functional loss manifestation of the veteran's flare-ups. We
explained that "case law and VA guidelines anticipate that examiners will offer flare opinions


       

, n.14.
       43

       44
            

(emphasis added).
       46
            

on estimates derived from information procured from relevant sources, including the lay
statements of veterans."47 We then sent the matter back for a new examination addressing the
veteran's reports of his flare-ups. In so doing, we had no concern on whether the Board first found
the veteran's assertion of flare-ups credible. Instead, we ordered a new exam that addressed the
veteran's testimony.48
         We see no reason to differentiate service-connection cases from musculoskeletal
evaluation case law when it comes to the requirement that medical opinions address lay evidence
to adequately inform the Board about the veteran's disability.49 What’s more, we see no reason to
accept the Secretary's invitation to throw lay statements into their own, least favored category. As
it stands, examiners are generally required to address relevant medical or service records without
a prior credibility determination by the factfinder.50
         If we accepted the Secretary's argument, an examiner would be required to address lay
statements only once a factfinder found those statements credible. This would make lay evidence
different from any other evidence that a medical examiner must address. It would also flip the
process on its head—examinations are normally given before credibility is decided—and the
Secretary's proposal would lead to pointless remands before a veteran would have an adequate
examination. We also agree with Mr. Miller that the Board's credibility determination can benefit
from information obtained in a medical opinion.
                                i. Role of Exams in Credibility Determinations
         Although it is the Board that must make a credibility determination, something it may not
outsource to a medical examiner, we have held that the Board should consider whether a favorable
medical opinion corroborates the veteran's assertions of an in-service injury. 51 Thus we have
recognized that medical evidence may play a role in the Board's evaluation of credibility.
         For instance, in Kahana v. Shinseki we held that the Board improperly made its own
medical determination when it determined that the veteran's ACL injury would have required

treatment in service.52 We also held that the Board improperly drafted its questions for a medical
exam about the veteran's knee by including its conclusion that there was no evidence of an in-
service injury in the question for the examiner.53 Even so, our opinion suggested questions to the
Board that would have led to a medical opinion that could help the Board determine whether the
veteran's reports were plausible. 54 We suggested the Board ask "whether there is any medical
reason to accept or reject the proposition that had the appellant had a right knee injury in service,
such injury could have [led] to his current condition" or "what types of symptoms would have been
caused by the type of ACL injury at issue."55 Thus, we laid out specific examples of how a medical
examination could inform the Board's credibility analysis.
        What is more, Judge Lance offered an even more in-depth look at how medical opinions
can inform credibility findings in his Kahana concurrence.56 He explained how the Board might
benefit from a medical opinion in making credibility determinations. He observed that, when
considering the veteran's assertions against the lack of corroborating evidence within service
treatment records, "the Board may reasonably conclude that a compound fracture of a bone would
have been observed and recorded, but would require medical evidence to determine whether a
particular type of cancer would have manifested observable symptoms in service that likely would
have been reported and recorded."57 Indeed, "a medical opinion may help resolve certain kinds of
disputed issues of fact, such as whether a particular injury occurred in service or the precise nature of
an intervening injury after service."58
        These examples reveal the useful role that a medical examiner can play in helping the
Board evaluate the credibility of the veteran's reports. The examiner can better inform the Board's
understanding of the medical feasibility of the veteran's lay statements. If an examiner explains
that the veteran's assertions are generally inconsistent with medical knowledge or implausible, the
Board can weigh that when addressing the veteran's credibility. Or an examiner may explain that

the veteran's reports about symptoms or an in-service injury align with how the disease or disability
is known to develop. Any way you look at it, the Board may benefit from this information in
makings its credibility determinations.59
        Thus, the examiner's obligation to address lay evidence cannot depend on a future finding
of credibility. The examiner must address the veteran's lay statements to provide the Board with
an adequate medical opinion.60 And absent an indication that the Board found that lay evidence
not credible, or had a reason not to address its credibility—such as in Barr where it found the
veteran not competent to report the symptoms—we will conclude that the Board found the lay
evidence credible and order a new examination that addresses this evidence. This does not involve
impermissible fact-finding but is consistent with our long practice of reviewing implicit factual
determinations. We should not remand a matter because the Board failed to expressly find every
piece of evidence credible or explain how it stacked up with the rest of the file.
                                    ii. Our Review of Implicit Fact-Finding
        After all, there "is a presumption that VA considered all of the evidence of record."61 And
"[t]he fact that [evidence] was not specifically mentioned in the Board's decision . . . is insufficient
to overcome this presumption." 62 Thus, the Board does not have to discuss all the evidence, but it
must discuss the relevant evidence.63 And in so doing, it must provide an explanation "for its
rejection of any material evidence favorable to the claimant."64 We note that the Secretary does
not ask us to overrule our own precedent nor, even more implausibly, ignore the Federal Circuit.
Thus, absent some indication to the contrary, we will continue to presume that the Board reviewed
the lay evidence in the record. And this means that, if credibility of some evidence was a relevant
issue for the Board, we would expect some discussion on the matter.
        Put another way, when the record includes the veteran's lay reports, which the Board did
not find to be not credible, we may ordinarily conclude that it made an implicit credibility
determination. If something as fundamental as the veteran's credibility were an issue, we would

expect the Board to say something. And because a determination about credibility is a finding of
fact, we should treat it like other findings of fact. 65
         For example, in McClain v. Nicholson,66 we read the Board's statements about medical
examinations and major depressive disorder to constitute an implicit finding that the veteran
suffered from a disorder due in part to service, although the disorder had resolved before
adjudication of the claim.67 We thus held that we would not overturn this favorable determination,
but remanded the matter "[b]ecause the Board implicitly found that Mr. McClain had depression
at some point during the processing of his claim."68
         And we've had no problems reviewing other implicit factual determinations by the Board.69
In fact, VA can implicitly deny entire claims under the "implicit denial rule." This rule "'provides
that, in certain circumstances, a claim for benefits will be deemed to have been denied, and thus
finally adjudicated, even if the [VA] did not expressly address that claim in its decision.'"70 If VA,
including the Board, can deny whole claims without expressly saying so, and this Court has
reviewed implicit fact-finding and denials, why make an exception now?71 It can’t be that we make
a special rule for implicit credibility determinations only to make denials easier for the Secretary.
Thus, we see no reason to treat credibility any differently.
         When the Board has made its decision without finding that the veteran is not competent to
report symptoms and nothing suggests that the Board failed to review the evidence at issue, we

           The Secretary agrees that we may review the Board's implicit findings of fact, but he asks that we not do
so here. See Miller v. Wilkie, U.S. Vet.App. No. 18-2796 (November 15, 2019: Secretary's Notice of Supplemental
Authorities).

may reasonably conclude that it implicitly found the veteran credible. This is particularly true
when, as here, the Board acknowledges the lay evidence and finds the veteran competent to offer
that evidence. At that point, we must surely expect the Board to say something if it sees something
wrong with the veteran's credibility. And this helps explain why McKinney is the proper rule much
of the time and why the proper remedy is to order a new examination where a VA medical
examiner fails to address the veteran's statements about medical history and the Board does not
address the credibility of those statements.
       In the end, we see no benefit to sending the case back to the Board to provide reasons or
bases for a credibility determination based on the same record. It already reviewed this record
once. It did not find an issue with the veteran's credibility. Although "[t]he Board is required to
provide a written statement of the reasons or bases for its findings and conclusions on all material
issues of fact and law presented in the record,"72 the Board plainly did not find credibility to be a
material issue.
       What is more, the Board's "statement must be adequate to enable a claimant to understand
the precise basis for the Board's decision, as well as to facilitate review in this Court."73 And, where
the Board has not found the veteran to not be credible or otherwise called credibility into question,
neither our review nor the veteran's understanding is generally frustrated when it comes to
credibility. If anything, it would be confusing for the Board to go over the exact same record yet,
suddenly, with no new evidence, divine a reason to question the veteran's credibility. Thus, we hold
that where the examiner failed to address the veteran's lay evidence and the Board fails to find the
veteran not credible or not competent to offer that lay evidence, the proper remedy is for VA to
obtain a new examination.
                                         D. Application to Mr. Miller
       With this clarified, we turn to Mr. Miller's case. There is no question that the March 2017
examinations are inadequate because the examiners failed to consider the veteran's lay statements.
Thus, the Board's determination that the duty to assist was met was clearly erroneous. And now
that we know that the proper remedy is for us to order that VA obtain a new examination, without

a pause for the Board to talk about Mr. Miller's credibility, we will order VA to obtain new
examinations.
         At oral argument, counsel for Mr. Miller suggested that the Board on remand phrase its
questions in the alternative. That is, Mr. Miller's counsel suggested that the Board ask the medical
examiner to offer an opinion on nexus while accepting Mr. Miller's statements as true and then
offer one while rejecting the veracity of Mr. Miller's reports. This proposal makes sense, as it
would leave the Board with an opinion that it can use if other evidence causes the Board to find
Mr. Miller not credible. After all, the Board may still find the veteran not credible. As we have
elaborated on,74 a medical opinion may inform the Board about credibility. This means that if the
Board found facts underlying the medical opinion not credible, it could destroy its probative
value.75 At the same time, not every medical opinion that considers a fact later found not credible
by the Board must lose all its probative value.
         Our cases have held that, where the Board finds the facts supporting the examiner's
conclusion not credible, the resulting medical opinion lacks probative value.76 That said, if the
opinion does not depend on the facts the Board later finds not credible, there should be no reason
for the opinion to have lesser probative value. For example, if a medical doctor explained that none
of a veteran's in-service injuries caused cancer, we see no reason why it would make the opinion
less probative if the Board later found that one of the injuries never occurred. Still, we will leave
it to the Board to craft its own questions. After all, it is VA that has expertise in developing these
claims. 77 And so, we order that VA obtain new examinations for the veteran's foot and GI
disabilities that adequately consider his lay assertions.
                                                     E. Fatigue
         We will also order a new examination addressing whether the veteran's fatigue should be
considered a qualifying chronic disability under 38 U.S.C. § 1117. The Secretary concedes too
much by offering that the Board failed to consider the veteran's statements about his fatigue and
offering a remand for better reasons or bases. We do not perceive a reasons or bases error by the

Board matching the one pushed by the Secretary. Nor does Mr. Miller point us to any evidence
that the Board ignored. Still, although we cannot identify any statements that VA failed to consider
related to fatigue, we agree with Mr. Miller that his fatigue symptoms warrant development under
the provisions covering Persian Gulf War veterans in section 1117. The Board likewise considered
the veteran's claim under these provisions and the April 2012 examination was done using a form
for Persian Gulf examinations.78
        But, as Mr. Miller points out, since the April 2012 examination, we have clarified that
when addressing whether a condition is a medically unexplained chronic multisymptom illness
(MUCMI), "'pathophysiology' and 'etiology' are decisive factors in determining whether an illness
is 'medically unexplained.'"79 In filling out the 2012 examination, however, the examiner failed to
answer whether both the etiology and pathophysiology of Mr. Miller's fatigue are known. Under
Stewart, answers to these questions are required to provide an adequate examination and for VA
to adequately consider whether the veteran's disability qualifies as chronic fatigue syndrome or a
different MUCMI under section 1117. Thus, VA also must provide Mr. Miller with a new medical
examination addressing his fatigue.
                                             F. No Broader Remedy
        Because these claims are being remanded, the Court need not address Miller's additional
arguments that would create no broader remedy than a remand.80 In pursuing his claims on remand,
the veteran will be free to submit additional argument and evidence on the remanded matters, and
he has 90 days to do so from the date of the postremand notice VA provides.81 The Board must
consider any such evidence or argument

7, 2018, Board decision is SET ASIDE, and the matter REMANDED for VA to obtain new
medical examinations for the veteran's claims and for further consideration consistent with this
opinion.
