The PACT Act: VA Presumptive Conditions Explained

Most toxic-exposure claims don't die on the diagnosis and they don't die on the service record. They die on the nexus, the medical opinion tying the two together. The PACT Act's whole point is that for a long list of conditions, you don't have to prove that link at all. The law supplies it.

Watch the full breakdown, then keep reading for the lists, the forms, and the reopen route.

What "presumptive" actually means

Ordinary service connection has three legs. You need a current diagnosed disability, something in service that could have caused it, and evidence linking the two. That's 38 C.F.R. § 3.303, which says service connection means the facts, shown by evidence, establish that the disability was incurred coincident with service.

A presumption replaces the third leg with a rule. 38 C.F.R. § 3.307(a) puts it plainly: a listed disease "will be considered to have been incurred in or aggravated by service under the circumstances outlined in this section even though there is no evidence of such disease during the period of service." And for the PACT Act's toxic-exposure conditions, 38 U.S.C. § 1120(a) uses the mandatory verb: a listed disease becoming manifest in a covered veteran shall be considered to have been incurred in or aggravated during service.

Shall. Not may.

What the PACT Act is

The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act (Pub. L. 117-168) was signed on August 10, 2022. Heath Robinson was an Ohio National Guard combat medic who served in Kosovo and Iraq and died in 2020 of a toxic-exposure-linked illness; his wife Danielle and their family led the fight to pass it.

The VA calls it "perhaps the largest health care and benefit expansion in VA history," and reports that in the law's first year it completed 458,659 PACT Act-related claims, "delivering more than $1.85 billion in earned benefits to Veterans and their survivors."

One thing to clear up right away: the phase-in is finished. The old schedule of conditions arriving in 2023, 2024 and 2025 was superseded when the VA accelerated all of them. VA.gov now says the PACT Act "is here to stay, and Veterans and survivors can file for benefits anytime."

The three exposure groups

Toxic-exposure presumptions sort into three groups, and which one you're in matters, because the covered places and dates are different for each.

Group one: burn pits and airborne hazards

This group turns on where and when you served, not on whether anyone wrote "burn pit" in your file. Two service windows:

Serve in one of those places in the right window with one of the listed conditions, and the connection is presumed. The conditions fall into two lists. First, cancers. VA.gov lists eleven categories, and the wording is deliberately broad, covering these cancers of any type:

Second, the breathing conditions: twelve of them, covering the lungs, the sinuses and the airways:

The Gulf War lane with no diagnosis at all

There's a second Gulf War route that a lot of veterans never hear about, and it is the one for people whose tests keep coming back normal. Under the undiagnosed-illness framework, a veteran who served in the Southwest Asia theater on or after August 2, 1990 (or in Afghanistan after September 19, 2001) and who has been ill for at least six months can be service-connected without a diagnosis at all.

What it covers: chronic fatigue syndrome, fibromyalgia, functional gastrointestinal disorders, medically unexplained chronic multisymptom illness, and signs and symptoms like cardiovascular problems, muscle and joint pain and headaches. It also covers certain infectious diseases (brucellosis, Q fever, malaria, West Nile virus) appearing within a year of separation. No causation proof required.

Group two: Agent Orange, widened

The Agent Orange presumption is older than the PACT Act, but the PACT Act widened it in two directions. It added hypertension and MGUS (monoclonal gammopathy of undetermined significance) as presumptive conditions, and it added qualifying locations: Thailand, Laos, Cambodia, Guam, American Samoa, Johnston Atoll and others, each with its own date range.

That second part matters more than it sounds. A veteran who was denied years ago because their service wasn't in Vietnam may be inside the presumption now purely because the map changed.

Group three: radiation

Radiation-exposed veterans have their own presumptive cancer list at 38 C.F.R. § 3.309(d). The PACT Act added qualifying sites to it: the Enewetak Atoll cleanup (1977–1980), Palomares, Spain (1966–1967), and Thule, Greenland (1968).

The catch-all: exposure your record already tracks

The location lists are not the only way in. 38 U.S.C. § 1119 says that in adjudicating a covered veteran's claim, the Secretary may consider any record of the veteran in an exposure tracking record system. The statute defines "toxic exposure risk activity" by cross-reference rather than by listing examples, so this isn't a second list to check yourself against. It's a route for a documented exposure that doesn't fit a named country and date.

The free toxic-exposure screening

Every veteran enrolled in VA health care gets a toxic-exposure screening, with a follow-up at least every five years. It is a conversation, not an exam: it asks about burn pits and other airborne hazards, Gulf War-related exposures, Agent Orange, radiation, Camp Lejeune contaminated water, and other exposures. You can ask for it in person or by telehealth. If you're not enrolled in VA health care, enrolling is the step that opens it.

What you still have to prove

The presumption is generous but it isn't automatic. Two things stay your job.

1. The diagnosis. The condition has to be diagnosed and in the record. You don't need to prove what caused it; you need a doctor to have named it.
2. The service. The right place in the right window, shown by your DD-214, deployment orders, or service personnel and treatment records. If your records are thin, buddy statements and unit records can pin down where and when.

Then you file. For a new claim that's VA Form 21-526EZ, and the one thing worth writing in plain words is that you are claiming the condition as presumptive under the PACT Act, naming your exposure group. That single sentence points the rater at the right rule.

Three traps

If you were denied before the law changed

This is the second move most veterans miss. If the VA denied your claim before your condition became presumptive, the reason for that denial, usually no proven nexus, no longer exists. That's a change in law, and it's a basis to have the claim looked at again.

The VA has said that if it denied a claim in the past and thinks you may be eligible now, it will try to contact you, and in the same breath, that "you don't need to wait for us to contact you before you file a Supplemental Claim." Treat the outreach as a courtesy, not a plan.

One reason not to wait: reopening on a change-in-law basis can set an earlier effective date than a brand-new claim would, and an earlier effective date can mean retroactive back pay. The rules there are case-specific, so file and let the VA set the date rather than trying to compute it yourself.

Survivors

If a veteran died of a condition that is presumptive now, the family has a claim. A surviving spouse, dependent child, or parent may qualify for Dependency and Indemnity Compensation (a monthly payment) and, depending on circumstances, Survivors Pension, accrued benefits, burial benefits, CHAMPVA health care, education and training benefits, and VA-backed home loans.

And the reopening route works the same way for survivors. A DIC claim denied before the law changed can be filed again on the same change-in-law basis. Free help filing is available from accredited Veterans Service Organizations and county veterans service officers; you never have to pay to file an initial claim.

Camp Lejeune is a separate thing

People often file Camp Lejeune under "PACT Act," and it's worth separating. Camp Lejeune contaminated water has its own VA presumption, and it is older than the PACT Act: under 38 C.F.R. § 3.307(a)(7), a veteran, reservist or National Guard member with no less than 30 days (consecutive or not) at Camp Lejeune between August 1, 1953 and December 31, 1987 is presumed to have been exposed to the contaminants in the water supply, with the disease list at § 3.309(f).

The PACT Act's Camp Lejeune piece was the Camp Lejeune Justice Act, which created a route to sue in federal court. That's a lawsuit, not a VA rating: a different process, a different filing, and it doesn't replace the disability claim.

The other presumptive paths

Toxic exposure isn't the only presumption in the regulations. 38 C.F.R. § 3.309 also carries chronic diseases with a one-year window after service, tropical diseases, and diseases specific to former prisoners of war, that last list with no time limit at all. If your condition isn't on a toxic-exposure list, it may still be presumptive under one of those.

Your next moves

1. Find your group: burn pits and airborne hazards, Agent Orange, or radiation. Or check the § 1119 route if a documented exposure doesn't fit a named location.
2. Check your condition against the live list at VA.gov, not against a copy.
3. Get the diagnosis into your medical record, and pull the DD-214 or orders that show where and when you served.
4. File VA Form 21-526EZ and say in plain words that you are claiming it as presumptive under the PACT Act.
5. Denied before the law changed? File VA Form 20-0995 and cite the change in law. Don't wait for the VA to call.
6. If you're enrolled in VA health care, ask for your toxic-exposure screening.

Thin service records are the most common thing standing between a veteran and a presumption they already qualify for. If someone you served with can put you at the place and time, that statement is competent evidence.
