Should I appeal or refile?

Within one year of the decision, file a Supplemental Claim if you have new evidence, or a Higher-Level Review if you believe there was a clear error. After one year, you generally must file a new claim, which typically comes with a new effective date.

Can more than one of these reasons apply to the same denial?

Yes, especially on multi-condition claims — different contentions can fail for entirely different reasons on the same decision letter, so it's worth reviewing each one separately.

Why Was My VA Claim Denied? The 7 Most Common Reasons

Most VA claim denials trace back to a small number of fixable issues. Here are the 7 most common reasons and how to address each.

By VA Benefits Help Guide Editorial Team

Quick answer

The most common reasons the VA denies a claim are: no current diagnosis, no in-service event, no nexus opinion, missed C&P exam, inadequate C&P exam, insufficient evidence of severity, and pre-existing condition without aggravation evidence.

A denial isn't the end of the road — it's a signal pointing to the exact piece of your claim that needs to be strengthened. The vast majority of denials come down to one of seven fixable problems, and matching the right fix to the actual reason is what separates a successful re-filing from a repeat denial.

1. No Current Diagnosis

Service connection legally requires three elements: an in-service event, a current diagnosis, and a nexus connecting them. No current diagnosis on file means the claim can't be approved regardless of how strong the other evidence is. Fix: get evaluated by a qualified provider before refiling, and make sure the diagnosis is clearly documented in your medical records.

2. No In-Service Event

The VA couldn't find evidence the injury or exposure actually occurred during service. Fix: gather buddy statements, personnel records, deck logs, or unit histories — and for MST claims specifically, alternate markers like documented unexplained transfers or noted behavioral changes can substitute for direct incident records.

3. No Nexus Opinion

No medical professional formally connected the diagnosis to your service. Fix: obtain a private nexus letter from a qualified provider that specifically uses 'at least as likely as not' language and explains the medical reasoning, not just a bare conclusion.

4. Missed C&P Exam

Missing a scheduled exam without rescheduling can trigger an automatic denial under 38 CFR § 3.655. Fix: contact the VA or scheduling contractor to reschedule as soon as possible, and document the specific reason you missed the original appointment.

5. Inadequate C&P Exam

The examiner didn't address every question required by the DBQ for your condition, or reached a conclusion inconsistent with the evidence already in your file. Fix: a Higher-Level Review specifically citing the inadequate exam as the error, since this doesn't require any new evidence to raise.

6. Insufficient Evidence of Severity

You successfully proved service connection, but the rating still came in lower than expected because your symptoms weren't documented clearly enough to support a higher level. Fix: gather more detailed treatment records, a personal symptom journal, and lay statements describing the real-world functional impact.

7. Pre-Existing Condition Without Aggravation Evidence

The VA determined the condition pre-dated your service, most often based on an entrance exam finding. Fix: gather evidence showing the condition was aggravated beyond its natural progression during service — a comparison between your entrance exam findings and later service or post-service records is usually the key piece here.

Conclusion

Every denial has a reason — and almost every reason has a fix. Read the rating decision carefully, identify which of the seven problems applies, and respond with targeted evidence that addresses that specific gap.
