Common records
VA identifies DD214 or separation records, service treatment records, and medical evidence related to the condition as common forms of supporting evidence. VA may obtain some materials with the veteran’s authorization.
Lay statements
A veteran or another person with direct knowledge may provide a written statement. VA describes Form 21-10210 and Form 21-4138 among available options.
Original disability claims
VA generally considers evidence of a current disability, an in-service event, injury, or disease, and a connection between them. Certain presumptions may alter how service connection is established.
Increased, secondary, and supplemental claims
The evidence VA discusses differs by claim type. Increased-rating claims concern changes in severity; secondary claims concern another condition linked to an existing service-connected disability; supplemental claims involve new and relevant evidence.
