VA Presumptive Conditions: Complete Guide Series
Plain-English guides to VA presumptive service connection: what a presumption is, which exposures and service periods create one, and what the VA's own regulations say about Agent Orange, burn pits, Gulf War illness, Camp Lejeune, radiation, chronic conditions within one year of discharge, and former prisoners of war.
Overview
Start here: presumptive conditions basics.
For most claims, a veteran has to show a medical link between a current condition and something that happened in service. For some conditions and some service periods, the VA presumes that link instead. These are called presumptive conditions.
Every guide in this series is built strictly from the VA's own published guidance at VA.gov and the federal regulations in Title 38 of the Code of Federal Regulations. Each article links to the exact source it relies on.
These guides are educational. They explain what the VA's rules say - they are not legal or claims advice, and they are not a substitute for an accredited representative, who can advise you about your specific claim.
