PACT Act: Complete Guide to Toxic Exposure VA Claims
The PACT Act is the largest expansion of toxic exposure benefits in VA history. This guide maps the whole system: burn pits, Agent Orange, radiation, and more.
The PACT Act is the most significant expansion of veteran benefits for toxic exposure in decades. Signed into law in August 2022, it broadened who the VA presumes was exposed to harmful substances in service and which conditions it will connect to that exposure without a separate nexus opinion. For millions of veterans, conditions the VA once denied are now presumptive, which means faster, stronger claims.
This pillar is the map for the entire toxic exposure topic. It explains what the PACT Act changed, the core idea of presumptive service connection, the major exposure categories, and how to file. Each section links to a deeper guide so you can go straight to your situation.
01
What the PACT Act is
The PACT Act, formally the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act, is a law that expanded VA health care and disability benefits for veterans exposed to toxic substances during service. It added new presumptive conditions, expanded the list of locations and eras that qualify for presumed exposure, and required the VA to improve toxic exposure screening.
02
The idea of presumptive service connection
The core concept is presumption. Normally a veteran must prove a current condition, an in service event, and a medical link between them. For presumptive conditions, the VA accepts the link automatically. If you have qualifying service and a listed condition, you do not have to prove the exposure caused it. This removes the hardest part of a toxic exposure claim.
03
Who the PACT Act covers
The PACT Act reaches several groups of veterans exposed to airborne hazards and other toxins.
- Post 9/11 veterans exposed to burn pits and airborne hazards in Southwest Asia and other theaters
- Vietnam era veterans exposed to Agent Orange, with expanded qualifying locations
- Veterans exposed to radiation through testing or cleanup activities
- Veterans and families connected to contaminated water at Camp Lejeune
- Gulf War veterans with qualifying chronic conditions
04
Burn pits and airborne hazards
One of the largest expansions covers burn pits, the open air pits used to dispose of waste at military sites, which released toxic smoke. The PACT Act made many cancers and respiratory conditions presumptive for veterans who served in qualifying locations during the Gulf War and post 9/11 eras. The burn pit guide covers the conditions and the qualifying service in depth.
05
Agent Orange
Agent Orange was a herbicide used during the Vietnam War. The VA has long recognized presumptive conditions for exposed veterans, and the PACT Act expanded both the list of conditions and the qualifying locations beyond Vietnam. If you served in a covered location and have a listed condition, the claim is presumptive.
06
Radiation exposure
Veterans exposed to ionizing radiation, through atmospheric nuclear testing, the occupation of Hiroshima and Nagasaki, or certain cleanup and testing activities, may have presumptive conditions, largely specific cancers. The radiation guide explains the qualifying activities and the conditions the VA presumes are related.
07
Camp Lejeune
Veterans, family members, and workers exposed to contaminated drinking water at Camp Lejeune between 1953 and 1987 have specific presumptive conditions for VA disability purposes, and a separate legal claims process exists as well. The Camp Lejeune guide explains both paths and how they differ.
08
Gulf War Illness
Many Gulf War veterans experience chronic multisymptom illness that does not fit a standard diagnosis. The VA can grant these as qualifying chronic disabilities for veterans who served in the Southwest Asia theater, without a specific diagnosis in many cases. The Gulf War guide covers how these claims work.
09
How to file a toxic exposure claim
You file a toxic exposure claim on VA Form 21-526EZ, the same form used for other disability claims. For a presumptive condition, you show qualifying service or exposure and a current diagnosis, and the VA supplies the link. The filing guide walks through the steps and the evidence that makes these claims move quickly.
10
If you were denied before
If the VA denied a condition before the PACT Act that is now presumptive, it is often worth filing again. A condition that failed for lack of a nexus may now be granted automatically under the new presumptions. Many veterans have reopened old denials successfully since the law took effect.
11
Why this matters for your rating
Toxic exposure conditions can carry significant ratings, and because presumptive claims remove the nexus fight, they are among the cleaner ways to raise a combined rating. A granted presumptive cancer or respiratory condition, or an Agent Orange presumptive, can also open the door to secondary claims and higher overall compensation.

Where to start
Start by matching your service to an exposure category, then check whether your condition is presumptive. If it is, the claim is often straightforward.
