Gathering Evidence

Gathering evidence for a VA disability claim involves collecting specific military, medical, and lay records to prove that you have a current condition that is linked to your service. The VA has a "duty to assist" you, but providing as much comprehensive documentation as possible can speed up the process.

Medical Evidence Logs (Symptom Logs)

"Medical evidence logs" are detailed records or diaries of your symptoms. They are a powerful tool because the VA considers veterans to be reliable reporters of their own symptoms.

For conditions where symptoms fluctuate (like migraines, chronic pain, or PTSD), consistent logging provides a clear picture of severity, frequency, and duration over time.

Effective symptom logs should detail:

  • Date & Time the symptom occurs.
  • Symptom(s) experienced (e.g., headache, panic attack).
  • Severity (e.g., scale of 1-10, or mild/moderate/severe).
  • Duration of the episode.
  • Impact on daily life (e.g., missed work, bed rest, medication).

Types of Medical Evidence for a VA Claim

The VA requires evidence to establish three things: a current diagnosis, an in-service event, and a medical link (nexus) between the two.

Service Medical Records (SMRs)

These records detail where you served, when you served, and any incidents or injuries that occurred during active duty. You can obtain these by submitting a Standard Form 180 (SF-180) to the National Archives.

VA Medical Records

If you receive care from the VA, these records show the continuity and progression of your condition post-service. You can access these online via your My HealtheVet premium account.

Private Medical Records

Documentation from non-VA healthcare providers is critical. You can submit these yourself or use VA Form 21-4142 to authorize the VA to gather them on your behalf.

Lay Evidence

These include statements from family, friends, or fellow service members (Buddy Statements) who have firsthand knowledge of your condition. Use these official forms:

Disability Benefits Questionnaires (DBQs)

DBQs help collect necessary medical information to process your disability claims. You can use these forms to submit medical evidence from your health care providers. This information helps to support your claims for disability benefits.

Please have your health care provider fill out and submit the appropriate forms for your claimed conditions.

Note: The VA does not pay or reimburse any expenses or costs incurred while completing and/or submitting DBQs.
