If you breathed the air near a burn pit in Iraq, Afghanistan, the Gulf, or a dozen other places, Congress may have already done the hardest part of your VA claim for you. The 2022 PACT Act — formally the Sergeant First Class Heath Robinson Honoring our PACT Act — added more than twenty conditions to the VA’s presumptive list for burn-pit and airborne-hazard exposure. For those conditions, you do not have to prove that your service caused them. The VA presumes it.
That single word — presumptive — is worth more than any nexus letter you could buy. This guide covers who qualifies (by location and time period), the full list of presumptive conditions, why you do not need a nexus letter, exactly how to file, the mistakes that get these claims bounced, and what to do if you are denied.
Why this matters so much
In an ordinary claim you have to prove three things: a current diagnosis, an in-service event, and a medical link between them. The link — the nexus — is where most claims die. A presumptive condition eliminates the nexus requirement entirely. Prove the diagnosis and the qualifying service, and the regulation supplies the rest.
Who qualifies: location + time period
Burn-pit presumptions turn on where and when you served. There are two main eligibility groups.
Gulf War era (on or after August 2, 1990)
Service in the Southwest Asia theater of operations on or after August 2, 1990. That theater includes:
- Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, and the United Arab Emirates
- The neighboring waters and the airspace above these locations
Post-9/11 era (on or after September 11, 2001)
Service on or after September 11, 2001 in the above locations or in:
- Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, and Yemen
If your DD-214, deployment orders, or travel/pay records put you in one of these places during the relevant window, the VA presumes you were exposed to fine particulate matter and burn-pit emissions. You do not have to prove you stood next to a specific pit.
The presumptive conditions (23+)
The PACT Act presumptive list splits into cancers and other illnesses. If you have a current diagnosis of any of these and qualifying service, you have a presumptive claim.
Presumptive cancers
- Brain cancer
- Gastrointestinal cancer of any type
- Glioblastoma
- Head cancer of any type
- Kidney cancer
- Lymphatic cancer of any type
- Lymphoma of any type
- Melanoma
- Neck cancer of any type
- Pancreatic cancer
- Reproductive cancer of any type
- Respiratory (breathing-related) cancer of any type
Presumptive illnesses
- Asthma (diagnosed after service)
- Chronic bronchitis
- Chronic obstructive pulmonary disease (COPD)
- Chronic rhinitis
- Chronic sinusitis
- Constrictive bronchiolitis or obliterative bronchiolitis
- Emphysema
- Granulomatous disease
- Interstitial lung disease (ILD)
- Pleuritis
- Pulmonary fibrosis
- Sarcoidosis
Several of these have their own rating guides
The respiratory conditions on this list are rated under 38 CFR § 4.97 and the airway codes. If your presumptive condition is asthma, rhinitis, sinusitis, or sleep-related, walk the rating schedule on the asthma, rhinitis, and sinusitis condition guides so you know which tier your diagnosis supports.
Why you don’t need a nexus letter
The VA codified the burn-pit presumptions in the particulate-matter regulation, 38 CFR § 3.320, alongside the broader presumptive framework in § 3.309. For a presumptive condition, the regulation does two things automatically:
- It concedes the exposure. Qualifying service in a covered location during the covered period = presumed exposure to fine airborne particulate matter. No exposure proof required.
- It presumes the connection. If you have a listed condition and the qualifying service, the condition is presumed to be related to that exposure — the nexus is built into the law.
That is the difference between a presumptive claim and a direct claim. In a direct claim you would pay for a private nexus opinion and hope the C&P examiner agrees. In a presumptive claim, the nexus argument is already won before you file. For the bigger picture of how presumptive service connection fits next to the other routes, see the four paths to service connection.
How to file a PACT Act claim
- Get the diagnosis documented. A current diagnosis of the listed condition from a VA or private provider. Make sure the diagnosis language matches a listed condition.
- Pull your service records. DD-214, deployment orders, or any record showing you were in a covered location during the covered window. This is what triggers the presumption.
- File VA Form 21-526EZ. List the presumptive condition by name. You can note in a short statement that you are claiming under the PACT Act / burn-pit presumption and 38 CFR § 3.320.
- Attend the C&P exam if scheduled. The VA may still examine you to confirm the current diagnosis and rate the severity — not to re-litigate service connection. Walk in prepared with the C&P Exam Prep tool.
Common mistakes that bounce PACT Act claims
- Service couldn’t be confirmed. If your records don’t clearly show the covered location and dates, the presumption doesn’t trigger. Submit the orders, not just the DD-214 summary.
- Diagnosis doesn’t match a listed term. “Breathing problems” isn’t a listed condition; “chronic obstructive pulmonary disease” is. Get the precise diagnosis on paper.
- Filed as direct, not presumptive. Say you’re claiming under the burn-pit presumption so the rater applies the right framework.
What to do if you’re denied
A PACT Act denial is usually a paperwork problem, not a merits problem. Identify which element failed — service confirmation or diagnosis — and refile through the right appeal lane:
- Missing or wrong evidence? File a Supplemental Claim with the new service records or a corrected diagnosis.
- Law clearly applied but VA got it wrong? A Higher-Level Review puts your file in front of a senior reviewer to fix the error of how it was decided.
The full appeals decision tree — which lane, the one-year window, and how to protect your effective date — is in the VA appeals guide. And the full PACT Act walkthrough, including the secondary conditions that often follow a respiratory diagnosis, lives on the PACT Act resource hub.

Quick answers
What is a presumptive condition under the PACT Act?
A presumptive condition is one the VA automatically presumes was caused by your military service if you meet the service requirements — so you do not have to prove the medical link (the "nexus") yourself. The PACT Act of 2022 added more than 20 conditions tied to burn pits and airborne hazards to the presumptive list. For these conditions, the VA concedes exposure based on where and when you served and presumes the condition is service-connected.
Who qualifies for burn pit presumptions?
Two broad groups. Gulf War era veterans who served on or after August 2, 1990 in the Southwest Asia theater of operations (including Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia, and the UAE), and post-9/11 veterans who served on or after September 11, 2001 in additional locations including Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, and Yemen. If you served in those places during those windows, exposure to burn pits and fine airborne particulate matter is presumed.
Do I need a nexus letter for a PACT Act presumptive condition?
No. That is the entire point of a presumptive. For the listed conditions, the VA presumes both the exposure (based on your qualifying service) and the connection between that exposure and your condition. You still need a current diagnosis of the listed condition and proof of qualifying service, but you do not need a private medical opinion linking the two — the regulation does that for you.
What conditions are presumptive under the PACT Act?
More than 20, in two buckets. Cancers: brain cancer, gastrointestinal cancer of any type, glioblastoma, head cancer of any type, kidney cancer, lymphatic cancer of any type, lymphoma of any type, melanoma, neck cancer of any type, pancreatic cancer, reproductive cancer of any type, and respiratory cancer of any type. Other illnesses: asthma (diagnosed after service), chronic bronchitis, COPD, chronic rhinitis, chronic sinusitis, constrictive or obliterative bronchiolitis, emphysema, granulomatous disease, interstitial lung disease, pleuritis, pulmonary fibrosis, and sarcoidosis.
How do I file a PACT Act claim?
File VA Form 21-526EZ listing the presumptive condition. Attach your diagnosis (private or VA medical records) and your service records showing qualifying location and dates (DD-214, deployment orders). You do not need a nexus letter. The VA may schedule a C&P exam to confirm the current diagnosis and severity, but the service-connection link is presumed.
What if my PACT Act claim is denied?
Common reasons: the VA could not confirm your qualifying service dates or location, your diagnosis did not exactly match a listed condition, or the claim was filed under direct (not presumptive) service connection. Fix the gap and file a Supplemental Claim with the missing service records or a corrected diagnosis. If the law clearly applied and the VA misapplied it, a Higher-Level Review is the faster lane.
