What is Service Connection?
The VA's determination that a veteran's disability or condition is related to their military service, which is required to receive VA disability compensation.
Understanding Service Connection
Service connection requires three elements: current disability, in-service event or injury, and a nexus (connection) between them. Connection can be direct, secondary (caused by another service-connected condition), or presumptive (certain conditions presumed connected for specific service periods or locations).
Examples
- 1Direct service connection for hearing loss from artillery
- 2Secondary connection for depression caused by chronic pain
- 3Presumptive connection for Agent Orange exposure in Vietnam
