The PACT Act, signed in August 2022, is the largest expansion of VA benefits in decades. It added a large set of presumptive conditions for toxic exposure - burn pits, air pollutants, and other hazards - and it widened the service locations and periods that qualify for the older Agent Orange presumption.
For veterans who were told for years that their condition was not presumptive, the Act changed the answer for many of them. This guide covers what changed and who qualifies.
The burn pit and toxic exposure presumptives
For Gulf War era and post-9/11 veterans, the Act created presumptions for a set of cancers and respiratory illnesses tied to burn pits and airborne hazards. The cancer list includes cancers of the head and neck, respiratory system, gastrointestinal system, kidney, and brain, melanoma, and lymphomas. The respiratory list includes chronic sinusitis and chronic rhinitis, asthma diagnosed after service, emphysema, COPD, chronic bronchitis, bronchiolitis, sarcoidosis, and pulmonary fibrosis, among others.
These presumptions work like the Agent Orange ones: qualifying service in specified locations during specified periods plus a current diagnosis, and no causation fight. The VA's PACT Act page lists the current conditions and qualifying periods.
Expanded Agent Orange coverage
The Act also expanded the herbicide side. It added new qualifying locations and periods for the existing Agent Orange presumptive list - including Thailand, Laos, Cambodia, Guam, and American Samoa - and extended some eligibility windows. Veterans previously denied because their service location was not recognized should revisit those decisions.
Our Agent Orange presumptive list guide covers the full list, including type 2 diabetes and hypertension, which remains the most relevant entry for most veterans.
Where veterans start
Every case is different, and there is no obligation at any step. When veterans want to understand what their records actually support, these are the two most common starting points:
- Medical records review
A licensed physician reviews your records for a $250 flat fee and identifies which conditions the available evidence may support. The fee is refunded in full if nothing supportable is identified.
- Nexus letter
When the records support one, a licensed provider writes the medical opinion that addresses the link between your condition and your service or an already service-connected disability.
What the Act does beyond presumptions
The Act expanded toxic exposure screenings - every enrolled veteran now receives periodic exposure questionnaires - and improved how exposure information flows into claims. It also extended health care eligibility to millions of veterans who previously had no path into VA care.
None of that changes the rating rules. Once a condition is service connected, the percentage still comes from the rating schedule - for diabetes, the management scale in our rating guide; for respiratory conditions, the VA's lung function testing.
If you were denied before the Act
A denial from before the Act's presumptions existed can be reopened under the new rules. The argument changes entirely: what was once a causation fight is now a qualifying-service question, and qualifying service is proven with a DD-214 and duty records rather than a medical opinion.
Our guide on why VA claims get denied helps identify what the old decision actually found missing, and a medical records review identifies which theories the current file supports before you refile.
