Open-air burn pits, sand and dust, and fuel and solvent fumes were a constant feature of deployments to Southwest Asia and later contingency operations. The PACT Act, signed in 2022, recognized that exposure by making a list of conditions presumptive for veterans with qualifying service.
This guide explains what the presumption does, which respiratory conditions are on the list, and what the claim looks like when a presumption is unavailable.
What a presumption actually does
A presumption removes one element of the claim. Where it applies, the VA presumes the in-service exposure and the medical link between exposure and condition. The veteran must still establish a current diagnosis and qualifying service.
That is why a presumptive claim can still be denied: not because the link was rejected, but because the diagnosis or the service dates and locations did not match.
Respiratory conditions on the presumptive list
The PACT Act added a set of respiratory conditions for veterans with qualifying burn pit and airborne hazards exposure. Among them:
- Asthma diagnosed after service
- Chronic rhinitis
- Chronic sinusitis
- Chronic bronchitis
- Emphysema
- Chronic obstructive pulmonary disease
- Granulomatous disease, interstitial lung disease, pleuritis, pulmonary fibrosis, and sarcoidosis
Qualifying service
Eligibility turns on where and when a veteran served. The VA publishes the covered locations and date ranges, which include Gulf War era service in Southwest Asia and post-9/11 service in a broader set of countries. Because the lists have been amended, the current VA page is the authoritative reference rather than any summary.
Veterans can also complete the VA's Airborne Hazards and Open Burn Pit Registry questionnaire, which documents exposure history.
When no presumption applies
Service outside the covered locations or periods does not end the claim. Direct service connection under 38 CFR 3.303 remains available where the evidence shows the condition was incurred in or caused by service, and 38 CFR 3.303(d) covers diseases first diagnosed after discharge.
In those cases the claim depends on a medical opinion that explains the exposure, the mechanism, and the timeline. Deck logs, unit histories, personnel records showing deployment locations, and buddy statements describing the exposure all become relevant.
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 respiratory condition and your service or an already service-connected disability.
Gulf War undiagnosed illness
38 CFR 3.317 provides a separate pathway for qualifying Persian Gulf veterans with chronic disability from an undiagnosed illness or a medically unexplained chronic multisymptom illness. Respiratory signs and symptoms are explicitly among the manifestations the regulation lists.
This route matters for veterans whose symptoms are well documented but have never resolved into a specific diagnosis.
How these claims are rated
A presumption establishes service connection; it does not set the evaluation. Asthma is still rated under Diagnostic Code 6602 on pulmonary function testing or medication requirements, and rhinitis and sinusitis under their own criteria. See asthma ratings and the C&P exam and rhinitis and sinusitis ratings explained.
Documenting exposure for the file
Even where a presumption applies, a well-documented exposure history strengthens the file and helps prevent disputes over qualifying service. Completing the VA's Airborne Hazards and Open Burn Pit Registry questionnaire, gathering deployment orders, and collecting buddy statements describing burn pit locations and frequency of exposure are all reasonable steps.
These records also matter for any condition not on the presumptive list, since they form the exposure half of a direct service connection claim.
Presumptive conditions beyond the respiratory list
The PACT Act presumptive list also includes certain cancers and other conditions outside the respiratory system. A veteran filing a respiratory claim under this presumption should review the full current list on VA.gov, since related conditions may also qualify and can sometimes be filed together.
Frequently asked questions
What does the PACT Act presume for burn pit exposure?
For veterans with qualifying service, the PACT Act presumes both the in-service exposure to burn pits and airborne hazards and the medical link between that exposure and a listed condition, removing the need to separately prove those elements.
Which respiratory conditions are on the PACT Act presumptive list?
Asthma diagnosed after service, chronic rhinitis, chronic sinusitis, chronic bronchitis, emphysema, COPD, and several interstitial and granulomatous lung diseases are included.
Can a claim still be denied if a presumption applies?
Yes. A presumptive claim can still be denied where the current diagnosis or the qualifying service dates and locations do not match what the presumption requires, even though the exposure and nexus elements are presumed.
What if my service does not qualify for the presumption?
The claim can still proceed under direct service connection, which requires a medical opinion connecting the current condition to documented exposure, deployment records, and the claimed timeline.
Does a presumption set the disability rating?
No. A presumption establishes service connection only. The evaluation is still assigned under the applicable diagnostic code, such as Diagnostic Code 6602 for asthma, based on the actual severity shown in the record.
