Toxic exposure
PACT Act presumptive conditions
Every condition VA lists as presumptive for toxic exposure, grouped by exposure, with the locations and date ranges that go with each one. Taken only from VA's own pages and the regulations, and checked August 6, 2026.
This page reports what VA publishes. It doesn't tell you if you qualify.
Only VA can decide eligibility on a specific claim, and nothing here is a recommendation to file or not file. If any of this looks like it applies to you, the right next step is a free accredited representative, who can look at your actual service and records. Find a VSO, or go straight to VA.gov.
What a presumption means
In VA's words: for some conditions VA automatically assumes, or presumes, that your service caused the condition. If you have a presumptive condition, you don't need to prove that your service caused it. You only need to meet the service requirements for the presumption.
That is a real and significant thing. Proving the medical link, the nexus, is the hardest part of most claims, and a presumption removes it. What it does not do is approve anything. You still need:
- A current diagnosis. A condition on the list means nothing without a diagnosed illness.
- Qualifying service. Each exposure track has its own definition of qualifying service, and they are not interchangeable.
- A discharge that isn't dishonorable.
Presumptions are also rebuttable. The regulation applies the exposure presumption unless there is, in its words, affirmative evidence to establish that the veteran was not exposed.
And if your condition or location isn't listed, VA is explicit that you can still apply; you would just need to show the connection the usual way.
Fair warning: VA's own pages don't agree with each other
This is the single biggest accuracy problem on this topic, and most sites paper over it. For burn pits alone, VA publishes at least five different versions of the cancer list across its own pages, and they don't match. Kidney cancer appears by name on some VA pages and is folded under "Genitourinary cancer" on others. Two VA pages give different end dates for Guam and American Samoa.
So the lists here reproduce VA's wording exactly, including VA's own typos, and note which VA page each name came from. A condition missing from one VA page is not necessarily excluded. If your condition is close to something on a list, that is a question for a representative rather than a reason to give up.
The four exposure tracks
These are separate tracks with separate rules, and they get conflated constantly. A condition can be presumptive under more than one.
Look up a condition
129 distinct conditions appear across the four tracks. Most people know their diagnosis and not which statute covers it, so each condition has its own page showing every exposure it's listed under.
If VA denied one of these before
VA states that if it denied your disability claim in the past and it now considers your condition presumptive, you can submit a Supplemental Claim and VA will review the case again. VA adds that it will try to contact you, but that you don't need to wait for it to reach you before filing.
What the PACT Act was
Public Law 117-168, signed August 10, 2022, formally the Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act. It expanded VA health care eligibility for veterans with toxic exposures, added more than 20 presumptive conditions, added presumptive exposure locations for Agent Orange and radiation, and required VA to offer toxic exposure screenings.
For the scale of it, see veterans by the numbers, where VA's own data shows more than two million PACT Act related claims completed and nearly half of all screened veterans reporting at least one potential exposure.
Where MusterVault fits
Toxic-exposure claims run on records: where you served and when, what you were diagnosed with and when. MusterVault keeps those encrypted and organized on your own computer and builds a packet for your representative. It organizes records; it never advises on a claim.
Educational only, not legal, medical, or claims advice. Every entry traces to va.gov, publichealth.va.gov, congress.gov, or ecfr.gov and was checked August 6, 2026. VA revises these pages often, so treat VA's live pages as authoritative over this one. MusterVault is not affiliated with the U.S. Department of Veterans Affairs.
