What Is Presumptive Service Connection?
Under normal service connection (38 C.F.R. 3.303), you need three things: a current diagnosis, an in-service event or exposure, and a medical nexus connecting the two. Presumptive service connection (38 C.F.R. 3.307, 3.309) eliminates the nexus requirement. If you served in a qualifying location during a qualifying period and you have a listed condition, the VA presumes it is connected to your service. You still need a current diagnosis, but you do not need a doctor to write a nexus letter linking it to service.
PACT Act (Public Law 117-168)
The PACT Act, signed August 10, 2022, is the most significant expansion of VA health care and benefits in decades. It establishes presumptive service connection for conditions linked to toxic exposures including burn pits, Agent Orange, and radiation. The PACT Act concedes toxic exposure for any veteran who served in a covered location during a covered period.
Burn Pit / Airborne Hazards Presumptives
Veterans who served in Southwest Asia, the Gulf War theater, or other designated locations after August 2, 1990, are covered. Conditions include:
Agent Orange Presumptives
Veterans who served in Vietnam (1962-1975), Thailand (specific Royal Thai Air Force bases), or locations where Agent Orange was tested or stored are covered. The PACT Act added several new conditions to the list in 2022-2024.
Gulf War Illness Presumptives
Veterans who served in the Gulf War theater (Southwest Asia) on or after August 2, 1990, may qualify for presumptive coverage for undiagnosed illness or medically unexplained chronic multi-symptom illness (MUCMI) under 38 C.F.R. 3.317.
Camp Lejeune Water Contamination
Veterans and family members who lived or worked at Camp Lejeune for at least 30 days between August 1, 1953, and December 31, 1987, are covered for conditions linked to contaminated water.
Radiation Exposure
Veterans who participated in nuclear weapons testing or were exposed to ionizing radiation during service are covered for specific cancers and other conditions.
How to File a Presumptive Claim
Filing a presumptive claim is the same 21-526EZ form as any other claim. The difference is in what evidence you need. For presumptive conditions: you need proof of service in a qualifying location (DD-214, deployment orders, personnel records) and a current medical diagnosis. You do NOT need a nexus letter from a doctor. The VA presumes the nexus. If the VA denies a presumptive claim by requiring a nexus letter, that is an error you can appeal.
