Condition related to active service
Evidence generally addresses a current disability, an event, injury, or disease during service, and a link between the two.
Veterans disability resource
Veterans Disability Guide.
A practical, evidence-focused overview of service connection, claim preparation, medical examinations, and independent medical review.
Begin with the question
What condition is claimed—and how is it connected?
A well-organized disability claim identifies the current condition, the relevant service event or established service-connected disability, and the evidence that connects them. The needed evidence varies with the type of claim, so the first step is to define the theory clearly.
Updated August 2026 · Based on current VA guidance
Service-connection pathways
Match the evidence to the type of claim.
Condition linked to a service-connected disability
Show the new diagnosis and explain how an established service-connected disability—or its treatment—caused or aggravated it.
Pre-existing or additional condition worsened
Document the relevant baseline, the measurable clinical worsening, its timing, and why service or a service-connected disability accounts for the change.
Qualifying service may establish the relationship
For certain conditions and qualifying service or exposures, VA may presume the nexus. The record still must establish that the veteran meets the applicable criteria.
Service-connected disability has worsened
Current medical or lay evidence should describe increased severity, functional limitations, treatment, and relevant complications.
New and relevant evidence after a decision
Identify evidence not previously considered that tends to prove or disprove a matter at issue in the prior decision.
Evidence file
Organize the record around seven essentials.
Claimed conditions
Use specific diagnoses where known and list each condition separately.
Service records
Gather DD214s, personnel records, service treatment records, orders, awards, and deployment or exposure evidence.
Current medical evidence
Include relevant VA and private records, testing, imaging, medication history, procedures, and specialist assessments.
Chronology
Connect service events, symptom onset, treatment, progression, diagnosis, and current functional effects.
Lay evidence
Use focused statements from the veteran or witnesses to describe observable events, symptoms, timing, and functional change.
Medical nexus
When needed, obtain a clear opinion that applies the medical evidence to the correct service-connection question.
Prior decisions
Review rating decisions, examinations, favorable findings, stated reasons, and missing evidence before adding duplicative material.
Claim process
Prepare, file, respond, and review.
Prepare the claim
Define each condition and theory. Gather the evidence you already have and identify records VA may need help obtaining.
Submit through an appropriate VA channel
VA accepts disability claims online and by other listed methods. VA Form 21-526EZ is used for disability compensation claims filed by mail.
Respond to evidence requests
Monitor communications, provide requested information promptly, and keep copies and confirmation of submissions.
Attend scheduled examinations
VA may request a compensation and pension examination when more medical information is needed. Some claims may be reviewed through the records-based ACE process.
Read the decision closely
Identify the conditions decided, favorable findings, rating and effective date, evidence considered, and the reasons for each determination.
C&P examination
Be accurate, complete, and specific.
- Attend the examination or promptly follow VA instructions if rescheduling is necessary.
- Describe symptoms honestly, including frequency, severity, duration, treatment, flare-ups, and functional limitations.
- Explain what happens on typical and difficult days without minimizing or exaggerating.
- Bring or submit records only as directed; do not assume an examiner has every private or newly submitted document.
- Remember that the examination gathers evidence. The examiner does not make the final benefits decision.
Avoidable problems
Clarity improves the usefulness of the record.
- Claiming symptoms without identifying the diagnosed or suspected condition
- Submitting large record sets without a focused chronology or explanation
- Using inconsistent dates or histories across statements and medical records
- Relying on a conclusion that contains no medical rationale
- Ignoring relevant contrary evidence or alternative causes
- Missing examinations or failing to respond to VA requests
- Sending protected medical information through an insecure channel
Qualified assistance
Accredited representatives can help.
VA states that accredited Veterans Service Organization representatives, attorneys, and claims agents can help with filing or decision review. Accredited VSO representation is free. Verify accreditation through VA before sharing records or paying for claim assistance.
