Asthma is one of the conditions the PACT Act made presumptive. If you are a "covered veteran" who served in certain countries on or after August 2, 1990, or on or after September 11, 2001, VA presumes that asthma diagnosed after service is service connected, and you do not need a medical opinion linking it to service. If your service does not fit those dates and places, the claim needs direct or secondary evidence, usually a clinician's explanation. The first step after a denial is to find which route your decision actually addressed.
The PACT Act presumption for asthma
The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics (PACT) Act became law on August 10, 2022. It added 38 U.S.C. § 1120, which lists asthma "that was diagnosed after service of the covered veteran" among the diseases presumed to have started in service, "notwithstanding that there is no record of evidence of such disease during the period of such service." A covered veteran, defined in 38 U.S.C. § 1119(c), is one who served at a duty station in, or in the airspace above:
- On or after August 2, 1990: Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, Somalia or the United Arab Emirates.
- On or after September 11, 2001: Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Yemen, Uzbekistan, or any other country VA determines is relevant.
VA's PACT Act page lists asthma diagnosed after service among the presumptive illnesses. A VA regulation, 38 C.F.R. § 3.320, also presumes asthma for fine particulate matter exposure, with a narrower list of qualifying service; the statute's list is broader. The words "deployment" or "burn pits" are not enough by themselves: compare your verified duty stations and dates with the list, and check when your asthma was first diagnosed. If VA denied asthma before the PACT Act, VA's Supplemental Claim page says you can ask for review of a newly presumptive condition.
Why the Board case below had no presumption
In Board decision A25093675, October 29, 2025, VA had already accepted three things: a current asthma diagnosis, the veteran's participation in toxic exposure risk activities as an armor crewman, and acute bronchitis during service. The Board of Veterans' Appeals (the Board) said it was bound by those favorable findings. But the veteran served from May 1977 to May 1980, years before either covered period began, so the asthma presumption could not apply. A conceded toxic exposure is not the same thing as the asthma presumption.
That left one question: was the asthma medically related to the exposures or the in-service bronchitis? An October 2023 VA opinion considered his total exposure and its combined effects and found no link. A February 2024 VA opinion said asthma and bronchitis are separate diagnoses that do not correlate, except that asthma can make bronchitis more likely. There was no competent opinion on the other side, and the veteran's own view of the cause did not count as medical evidence. The Board denied service connection for asthma.
The lesson: when no presumption applies, a denial that already accepts the diagnosis and the exposure is about the medical link, and another test showing that you have asthma will not answer it. A reasoned opinion that addresses the same facts is what was missing. In a different Board case, one private nexus opinion carried an asthma claim after five earlier denials.
Direct and secondary theories
Direct service connection: VA compares an in-service respiratory event, treatment or exposure with the current diagnosis and a clinician's explanation. A service record of coughing does not by itself diagnose asthma, and a normal separation exam does not by itself settle a later medical question. VA's evidence guide explains the medical and lay sources for a direct claim.
Secondary service connection: If you claimed that a service-connected condition caused or worsened your asthma, locate that earlier award and the medical reasoning. Under 38 C.F.R. § 3.310, causing a condition and aggravating it are separate questions. A general study or another veteran's award cannot establish the link in your record.
The asthma condition guide covers the rating criteria. If service connection is already granted and the dispute is the rating level, the asthma evidence guide covers prescriptions, actual use and breathing tests.
Asthma theory and evidence map
| Theory or element | VA's exact finding | Dated source to compare | What is still unknown? |
|---|---|---|---|
| Current asthma diagnosis | Clinician assessment and test report | ||
| Duty stations and dates for § 1120 | Personnel or deployment records | ||
| Date of first asthma diagnosis | First diagnosis and later records | ||
| Direct in-service event, if claimed | Service and treatment records; first-hand account | ||
| Service-connected cause, if claimed | The earlier VA award | ||
| Causation or aggravation opinion, if claimed | Clinician's reasoning, baseline and course | ||
| Evidence VA did not list | Specific record, date, page |
Leave unclaimed theories blank. You can accurately record your service, observations, treatment dates and missing records without writing a clinician's conclusion for them.
Asthma appeals: what the data can and cannot show
In Claim Raven's analysis of 2024 to 2025 Board decisions, asthma was a decided issue in 577 condition records: 43.7% favorable, 41.6% denied and 14.7% remanded. Among 183 denied asthma records with a classified reason, 62.8% concerned the rating level (severity criteria not met) and 14.2% procedural or timeliness grounds, so this label mixes rating disputes with service-connection disputes like the one on this page. These appeals were already disputed before they reached the Board, so the numbers describe patterns rather than odds.
Use the right route for the next step
If you have a record VA did not see, such as proof of a covered duty station, an earlier diagnosis date, or a medical opinion, that is new evidence for a Supplemental Claim. If VA had your covered service in the file and did not apply the presumption, a Higher-Level Review looks at the same record for that error. A presumption change and an earlier denial can raise case-specific effective-date questions, so read VA's decision review FAQ and your letter before choosing. When the gap is the medical link, the no-nexus denial guide explains what kind of evidence answers it.
To check which asthma route your notice addressed, Claim Raven's Raven Eye tool, offered on this page, can explain the passage beside the original text. Claim Raven sells the tool; it cannot verify your service or issue a medical opinion.
