The PACT Act: toxic-exposure benefits explained

The PACT Act (the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act) is the largest expansion of VA health care and benefits in the department's history. Signed into law in August 2022, it adds more than 20 presumptive conditions for veterans exposed to burn pits, Agent Orange, radiation, and other toxic substances — and expands who is eligible for VA health care.

What "presumptive" means (and why it matters)

Normally, to get service-connected disability pay you have to prove your illness was caused by your service. A presumptive condition is a legal shortcut: if you have a qualifying diagnosis and you served in an eligible time and place, the VA presumes the connection — you don't have to prove causation. That removes the hardest part of most claims.

You still need two things: (1) a current medical diagnosis of a listed condition, and (2) proof of qualifying service (dates and locations, usually from your records).

Who qualifies — the three main exposure groups

1. Burn pits & other post-9/11 exposures

Generally eligible if you served on or after September 11, 2001 in (or in the airspace above) Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, Yemen, and certain other locations. The Act added roughly a dozen respiratory illnesses and a range of cancers to the presumptive list for this group.

2. Agent Orange & other herbicides (Vietnam era)

Generally eligible if you served January 9, 1962 – May 7, 1975 in Vietnam, Thailand, Laos, Cambodia, Guam, American Samoa, Johnston Atoll, and other listed areas. Recently added presumptives include hypertension (high blood pressure) and monoclonal gammopathy of undetermined significance (MGUS).

3. Radiation exposure

Adds coverage for participants in the cleanup responses at Enewetak Atoll, Palomares (Spain), and Thule Air Force Base (Greenland) during the specified periods.

Secondary conditions — commonly missed

A service-connected condition can cause or worsen other conditions, which can be rated too (this needs a medical opinion linking the two — a "nexus"). Common examples veterans overlook:

• Sleep apnea secondary to a service-connected respiratory or weight-related condition
• Depression or anxiety secondary to chronic pain or a serious illness
• Erectile dysfunction secondary to hypertension, diabetes, or PTSD medication

Free toxic-exposure screening

Every veteran enrolled in VA health care is entitled to a free toxic-exposure screening — ask for it at your next VA appointment or when you enroll.

How to file

1. Gather your diagnosis and your service dates/locations.
2. Consider submitting an Intent to File first — it can set your effective date while you prepare the full claim.
3. File at VA.gov (PACT Act), or work with a free, accredited Veterans Service Officer (VSO) — never pay a percentage of your back pay to file an initial claim.
