What Evidence Does the VA Need to Approve a Disability Claim?
Updated: Oct 5
Many veterans assume that filing a VA disability claim simply requires explaining what happened during military service and describing current symptoms. In reality, the Department of Veterans Affairs evaluates claims based on specific types of evidence.
Understanding what evidence the VA looks for can help veterans build stronger claims and avoid some of the most common reasons for denial.
The Three Core Elements of a VA Disability Claim
For direct service connection, VA generally considers three key elements. Presumptive and secondary claims can follow different evidentiary routes:
• Evidence of a current disability
• Evidence of an in-service event, injury, illness, or exposure
• A medical connection (nexus) between the current condition and military service
The evidence needed depends on the claim and the applicable legal theory. Medical records and competent lay evidence may both matter; a qualifying presumption may establish the connection to service.
You can learn more about these requirements in the article “Three Key Elements of Direct VA Service Connection.”
Medical Evidence
Medical evidence is often the most important part of a VA disability claim.
This may include:
• medical records from VA providers
• records from private doctors or specialists
• diagnostic tests such as imaging or sleep studies
• treatment history and clinical notes
• compensation and pension (C&P) exam reports
A diagnosis is often important, and some conditions have specific diagnostic requirements. But a diagnosed underlying pathology is not universally required; pain causing functional impairment of earning capacity may qualify under Saunders v. Wilkie.
Service Records
Service records help demonstrate that an event or exposure occurred during military service.
These records may include:
• service treatment records
• personnel records
• deployment or duty assignments
• documentation of injuries or illnesses during service
In some cases, the event may not be fully documented in the service record. When that happens, additional evidence may still help support the claim.
Nexus Evidence
A nexus is medical evidence linking the current condition to military service.
This connection may be established through:
• medical opinions from treating physicians
• independent medical evaluations
• VA C&P exam reports
• medical literature supporting the relationship between conditions
Without a clear nexus, the VA may conclude that the condition is not service connected.
Lay Statements
Lay statements can also be important pieces of evidence.
These statements may come from:
• the veteran
• family members
• fellow service members
• coworkers or supervisors
Lay statements often describe symptoms, limitations, or events that may not appear in medical records. While they do not replace medical evidence, they can help provide important context.
Why Claims Are Often Denied
Many VA disability claims are denied because one of the required elements is missing or not clearly supported by the available evidence.
For example:
• a diagnosis may be unclear or incomplete
• service records may not clearly document the event
• the VA may conclude that the medical connection between service and the condition is not established
Understanding what evidence the VA looks for can help veterans identify gaps and strengthen their claims.
