Veterans with at least 90 days continuous Active Duty service who receive a diagnosis of specific diseases within defined timeframes and achieve at least a 10% disability evaluation within those periods qualify for presumptive service-connection.
IMPORTANT NOTES:
- Only conditions explicitly listed qualify for presumptive service-connection under 38 CFR 3.307(a) — not all diseases diagnosed within one year.
- Veterans may still seek service-connection for unlisted conditions through the standard claims process.
- National Guard and Reservists with 90+ days service do NOT automatically qualify unless VA grants service-connection linked to Active Duty Training or Inactive Duty Training periods.
