A VA C&P exam is inadequate when it does not let the adjudicator make a fully informed decision: it rests on an inaccurate or incomplete history, does not describe the disability in enough detail to rate it, answers the wrong question, or states a conclusion without reasoning. Once VA provides an exam, it must be adequate (Barr v. Nicholson, 21 Vet. App. 303, 311 (2007)). Reliance on an inadequate exam is a duty-to-assist error, and you raise it in the review lane that fits the case.
The exam is usually the most important document in the file, because the decision almost always follows it. Reading it against the record is where most of the case is won or lost.
This guide is general information for representatives, not legal advice about any particular case.
When VA has to provide an exam at all
In a compensation claim, VA must provide an exam or obtain an opinion when it is necessary to decide the claim (38 C.F.R. § 3.159(c)(4)(i)). It is necessary when the record lacks sufficient competent medical evidence to decide the claim but:
- 1contains competent lay or medical evidence of a current diagnosed disability or persistent or recurrent symptoms,
- 2establishes an in-service event, injury, or disease (or a qualifying presumptive disease in the presumptive period), and
- 3indicates that the disability or symptoms may be associated with service or with another service-connected disability.
For a supplemental claim, this duty applies only once new and relevant evidence is presented or secured (§ 3.159(c)(4)(iii)). No exam where all three elements were in the record is its own duty-to-assist error, separate from an exam that was provided and fell short.
The legal standard for adequacy
Three CAVC decisions supply most of the test.
- Barr v. Nicholson, 21 Vet. App. 303, 311 (2007). Once VA undertakes to provide an exam when developing a service connection claim, even if not statutorily obligated to, it must provide an adequate one or, at a minimum, notify the veteran why one will not or cannot be provided.
- Stefl v. Nicholson, 21 Vet. App. 120, 123 (2007). An opinion is adequate when it is based on consideration of the veteran's prior medical history and examinations and describes the disability in sufficient detail that the adjudicator's evaluation is a fully informed one.
- Nieves-Rodriguez v. Peake, 22 Vet. App. 295, 304 (2008). The probative value of a medical opinion comes from its reasoning: "the factually accurate, fully articulated, sound reasoning for the conclusion," not the bare fact that the examiner reviewed the claims file.
Put together: the examiner must know the facts, address the right question, describe the disability fully, and explain the conclusion.
Defects to look for
- No rationale. A conclusion with data but no explanation connecting the two. This is the most common defect in a negative opinion.
- A wrong or incomplete factual premise. The examiner misstates the in-service event, the onset date, or the treatment history. Note the exam page and the record page that contradicts it.
- The wrong question. A direct-service-connection opinion on a claim filed as secondary, or the reverse.
- Causation without aggravation. Section 3.310 covers disability proximately due to a service-connected condition (§ 3.310(a)) and any increase in severity of a nonservice-connected condition proximately due to it (§ 3.310(b)). An opinion that addresses only causation answers half the question.
- The veteran's own account left out. Lay statements about symptoms, onset, and continuity that the examiner never addresses.
- A rating exam that cannot be rated. Findings missing for the criteria the diagnostic code uses, such as range-of-motion measurements, frequency of attacks, or functional effects during flare-ups.
- Diagnoses recorded but never addressed. An examiner notes a condition the opinion never connects or rules out. Check whether any decision ever decided it; see finding an unadjudicated claim.
What to do about it
Before VA decides
Put the defect in writing and ask for a new exam or an addendum opinion. Identify the exam by date, quote the defect, and cite the record pages that show it. A specific request is easier to act on than "the exam was inadequate."
After VA decides: the three lanes
| Lane | What it does with an inadequate exam |
|---|---|
| Higher-level review (20-0996) | The record is closed: the reviewer may not consider evidence added after the decision under review (§ 3.2601(f)). If the reviewer finds a duty-to-assist error that existed when VA decided the claim and cannot grant the maximum benefit, the claim must be returned for correction and readjudication (§ 3.2601(g)). |
| Supplemental claim (20-0995) | You submit new and relevant evidence, often a private medical opinion that answers the question the VA exam did not. Relevant evidence includes evidence raising a theory of entitlement not previously addressed (§ 3.2501). |
| Board appeal (10182) | Unless the issue can be granted in full, the Board must remand for correction of a duty-to-assist error that occurred before the decision on appeal (38 C.F.R. § 20.802(a)). |
The choice turns on time and control. A higher-level review or Board remand sends the defect back for VA to fix, which usually means another VA exam. A supplemental claim lets you supply the missing opinion yourself. See duty to assist errors and choosing the review lane.
At the Court
If the Board relied on an inadequate exam, that reliance can be argued at the Court of Appeals for Veterans Claims as an error in the Board's decision, with citations to the exam and the record pages that show the defect. See what happens after you file a Notice of Appeal.
Frequently asked questions
What makes a VA C&P exam inadequate?
An exam is inadequate when it does not let the adjudicator make a fully informed decision: an inaccurate or incomplete history, too little detail to rate the disability, the wrong question answered, or a conclusion with no reasoning (Stefl v. Nicholson, 21 Vet. App. 120, 123 (2007); Nieves-Rodriguez v. Peake, 22 Vet. App. 295, 304 (2008)).
Does VA have to give an adequate exam even if it did not have to give one at all?
The CAVC held that once VA undertakes to provide an exam, even if not statutorily obligated to, it must provide an adequate one or tell the veteran why one will not or cannot be provided (Barr v. Nicholson, 21 Vet. App. 303, 311 (2007)).
Is an inadequate C&P exam a duty-to-assist error?
It is generally argued that way, because the duty to assist under 38 C.F.R. § 3.159(c)(4) includes providing an exam or opinion when one is necessary. A higher-level reviewer who finds a duty-to-assist error and cannot grant the maximum benefit must return the claim (§ 3.2601(g)), and the Board must remand unless it can grant in full (§ 20.802(a)).
Can I submit a private opinion in a higher-level review?
The higher-level review record is limited to the evidence of record when VA issued notice of the decision under review (§ 3.2601(f)). A new private opinion goes in through a supplemental claim or a Board docket that accepts evidence.
Does it matter that the examiner reviewed the claims file?
Claims file review alone does not make an opinion adequate. The CAVC has said probative value comes from factually accurate, fully articulated, sound reasoning, not from the fact of file review (Nieves-Rodriguez v. Peake, 22 Vet. App. 295, 304 (2008)).
