The PACT Act presumptive conditions: what toxic-exposure veterans can claim
The PACT Act made dozens of burn-pit, Agent Orange, and other toxic-exposure conditions presumptive — so eligible veterans don't have to prove the exposure caused them. Here's how the presumption works and who qualifies.
The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics (PACT) Act, signed into law on August 10, 2022, is the largest expansion of VA disability benefits for toxic-exposed veterans in decades. Its central change is that it makes a long list of conditions “presumptive” for veterans with qualifying service.
What “presumptive” means for your claim
Normally a veteran must prove a “nexus” — a medical link — between their military service and their current condition. When a condition is presumptive, the VA accepts that the qualifying service caused it, so you generally only need to show two things: that you have the diagnosed condition, and that you served in a qualifying time and place. That removes the single hardest part of most toxic-exposure claims.
Which conditions and exposures are covered
The PACT Act added more than 20 presumptive conditions tied to burn pits and other airborne hazards — including several respiratory illnesses and cancers — for Gulf War and post-9/11 veterans. It also added hypertension (high blood pressure) and monoclonal gammopathy of undetermined significance (MGUS) as Agent Orange presumptives, and expanded the list of locations and time periods recognized for Agent Orange and Gulf War exposure. The VA maintains the authoritative, current list of qualifying conditions and locations.
What to do next
If you have a condition on the presumptive list and qualifying service, you may be able to file or re-file even if you were previously denied. Filing an Intent to File first locks in your effective date and can protect up to a year of back pay while you gather evidence. Check the official VA list below for the conditions and locations that apply to you.
