Evidence for a VA Disability Claim

Start with the three pieces of a direct-service claim

A condition can be real and still be denied if VA cannot establish one of the required parts. Presumptions may supply part of the connection for some conditions and service circumstances. Check the rules for the exact condition rather than assuming every claim needs the same evidence.

• Current condition: a diagnosis, symptoms, test results, or other evidence of a current disability.
• In-service event: service treatment records, personnel records, deployment records, incident reports, or credible lay statements.
• Connection: medical or other competent evidence that links the current condition to service.

Gather service and medical records

Useful records may include your DD-214, service treatment records, personnel or deployment records, VA treatment records, private doctor and hospital records, imaging, lab results, prescriptions, and specialist reports. Identify dates and locations so VA can request records it is responsible for obtaining. For private records, provide the information or authorization VA requests and follow up if the records do not arrive.

You can request copies of military records and VA health records through the official VA tools. Keep your own copies and make a simple list of what was submitted and when. Do not assume a record is in the claim file just because a clinic has it.

What a nexus letter can—and cannot—do

A nexus opinion is a medical opinion that explains whether a current condition is linked to an in-service event or another service-connected condition. A useful opinion identifies the records and history considered, explains the medical reasoning, and addresses relevant facts that point the other way. A bare conclusion or a copied template may not answer VA's question.

A nexus letter is not required in every claim, and no phrase guarantees approval. VA may request its own medical opinion or C&P exam. If you submit a private opinion, make sure it is accurate, signed by a qualified clinician, and consistent with the medical record.

Buddy statements and other lay evidence

You, family members, fellow service members, coworkers, and others may describe events they witnessed or changes they observed. A buddy statement can explain symptoms, timing, limitations, or an in-service event in the writer's own words. Lay evidence is not a substitute for every medical diagnosis, but VA must review it with the other evidence.

Use specific examples and dates when possible. A statement should be truthful, firsthand where possible, and consistent with the rest of the file. VA Form 21-10210 is the Lay or Witness Statement form.

Organize evidence and meet requests

Label uploads by condition and type, keep confirmation receipts, and respond to VA's evidence requests by the deadline in the notice. If you are using a Fully Developed Claim, understand what you are certifying and what evidence VA may still gather. If you later receive a denial, compare the reasons section with the evidence VA says it reviewed.
