Top Reasons VA Disability Claims Get Denied

The three elements VA must find

Direct service connection under 38 CFR § 3.303 requires three findings: (1) a current diagnosed disability, (2) an in-service incurrence or aggravation of a disease or injury, and (3) a medical nexus linking the current disability to that in-service event. A denial almost always traces to one of these three boxes being unchecked in the rater's reading of the file.

Presumptive claims under PACT, Agent Orange, Gulf War, and Camp Lejeune relax the nexus requirement when service location and a qualifying condition both appear in the record. Secondary claims under § 3.310 substitute a nexus to an already service-connected condition for the in-service nexus.

1. No current diagnosis in the file

VA cannot grant a condition the medical record does not currently show. A claim filed on lay statements alone — without a treating provider's diagnosis in VA, private, or military treatment records — is the most common single denial driver.

Fix: obtain a current evaluation from a treating provider, then file a Supplemental Claim with the diagnosis as new and relevant evidence. The VA's duty to assist may also require a new C&P exam if the claim is reopened with a credible indication of a current disability.

2. No in-service event documented

If service treatment records (STRs) do not show the event, exposure, or injury, the rater has nothing to anchor in-service incurrence to. Combat veterans get the benefit of § 1154(b) (combat presumption of incurrence), but non-combat veterans need either STR entries, performance evaluations, awards citations, deployment records, or credible lay statements (buddy statements on VA Form 21-10210).

Fix: request a full copy of the STRs and personnel file, gather buddy statements that specifically describe what was seen, and consider whether a presumptive pathway (PACT location, Gulf War theater, Camp Lejeune dates) applies in place of direct documentation.

3. Missing medical nexus

Even with a current diagnosis and in-service event, VA needs a medical opinion that connects them. A 'nexus opinion' from a qualified clinician should state the likelihood (at least as likely as not, more likely than not), identify the evidence reviewed, and provide a rationale.

Fix: a private medical opinion from a treating physician, specialist, or independent medical examiner is often what moves a denial to a grant on a Supplemental Claim. Oakridge Claims coordinates with the veteran on what an adequate nexus opinion needs to address — but we do not author the medical opinion itself; it must come from a qualified independent clinician.

4. Inadequate C&P exam

An inadequate C&P exam under Barr v. Nicholson (21 Vet. App. 303, 2007) is grounds for a Higher-Level Review based on a duty-to-assist error. Common inadequacies: the examiner did not review the C-file, used the wrong DBQ, did not address all symptoms, gave an opinion without rationale, or applied the wrong legal standard ('caused by' instead of 'at least as likely as not').

Fix: request a Higher-Level Review and identify the specific inadequacy in the informal conference. If granted as a duty-to-assist error, the claim is returned for a corrected exam with the original effective date preserved.

5. Misapplied rating criterion

Sometimes the grant is correct but the percentage is wrong. The rater may have selected a diagnostic code that does not capture all symptoms, ignored functional loss under DeLuca v. Brown (8 Vet. App. 202, 1995), or stopped at the schedular ceiling without considering extraschedular referral under § 3.321(b).

Fix: a Higher-Level Review citing the specific rating-schedule paragraph misapplied, or a Supplemental Claim with new evidence of severity (range-of-motion measurements, sleep study AHI, mental-health functional impact statements).

6. Missed deadlines and effective-date traps

Filing a Supplemental Claim more than one year after a prior decision generally moves the effective date to the new filing date rather than preserving the original. Missing the one-year window for HLR or Board appeal eliminates those lanes entirely.

Fix: file an Intent to File (VA Form 21-0966) the day you decide to pursue a claim. It preserves the effective date for one year while evidence is gathered.

Where these claims break down

• ×Filing without a current diagnosis in the medical record.
• ×Submitting lay statements about events the VA never developed in the C-file.
• ×Accepting a C&P exam that did not address all claimed symptoms.
• ×Choosing Higher-Level Review when the file needs new evidence — or vice versa.
• ×Letting the one-year decision-review window expire and losing back pay.
• ×Filing a Supplemental Claim without identifying what is new and what is relevant about the new evidence.
