Asthma is one of the top conditions covered under the PACT Act — and one of the most underrated by veterans who don't know how VA evaluates it. Over 500,000 veterans currently have service-connected asthma, and the 2022 PACT Act dramatically expanded who qualifies by adding burn pit and toxic exposure presumptives. VA rates asthma under Diagnostic Code 6602 at 0%, 10%, 20%, 50%, or 60% — but the key to getting the right rating isn't just having a diagnosis. It's having the right pulmonary test results and documentation of how asthma limits your daily life. This guide explains exactly what VA looks for, what evidence you need, and how to file — whether you're applying for the first time or appealing a denial.
VA rates asthma under 38 CFR Part 4, Section 4.97, Diagnostic Code 6602 (Bronchial asthma). The rating system focuses on two things: pulmonary function test (PFT) results and functional impairment — how much asthma limits your ability to work, exercise, and function daily.
This is the critical point veterans miss: VA doesn't rate you based on how often you use an inhaler or how bad you feel during attacks. It rates based on measurable lung function compared to normal values. If you haven't had recent PFTs, your rating will almost certainly be lower than it should be.
| Rating | What VA Looks For | 2026 Monthly Pay (Veteran Only) |
|---|---|---|
| 60% | FEV-1 less than 40% predicted; or FEV-1/FVC less than 40%; or more than one attack per week with episodes of respiratory failure; or requires daily use of systemic (oral or parenteral) corticosteroids | $1,395.93 |
| 50% | FEV-1 of 40%–55% predicted; or FEV-1/FVC of 40%–55%; or at least monthly visits to physician for persistent symptoms; or use of oral/injected corticosteroids more than 3 times per year | $1,075.16 |
| 30% | FEV-1 of 56%–70% predicted; or FEV-1/FVC of 56%–70%; or daily inhalational or oral bronchodilator therapy; or inhalational anti-inflammatory medication | $508.05 |
| 10% | FEV-1 of 71%–80% predicted; or FEV-1/FVC of 71%–80%; or intermittent inhalational or oral bronchodilator therapy | $175.51 |
| 0% | Asthma confirmed but PFT results are within normal range (above 80% predicted) and no regular medication required | $0 (no pay; still service-connected) |
Note: 2026 VA disability rates above are for a veteran with no dependents. Rates increase with dependents.
A veteran with an asthma diagnosis but no pulmonary function test results on file will typically be rated 0% — even if their asthma is severe. The same veteran who submits a PFT showing FEV-1 of 60% will be rated 30%. It's not about having worse asthma. It's about having documented evidence of lung function impairment. Get PFTs before your C&P exam.
If you've never heard of a pulmonary function test, here's a plain-English explanation: it's a breathing test done at a pulmonologist's or respiratory therapy office. You breathe into a machine that measures how much air you can move in and out of your lungs and how fast you can do it.
The two numbers VA cares about most are:
These numbers directly map to DC 6602 ratings. If your PFT shows FEV-1 at 62%, you're in the 30% rating range. If it shows FEV-1 at 48%, you're in the 50% rating range. Request PFTs from your pulmonologist or primary care physician before filing.
The PACT Act of 2022 was a landmark expansion of VA disability presumptives, and asthma was one of the biggest beneficiaries. Under the PACT Act, veterans exposed to specific toxic hazards are presumed to have service-connected asthma — meaning VA cannot require you to prove that your military service caused your asthma. Exposure + diagnosis = entitlement.
The practical impact has been dramatic: asthma approvals among post-9/11 veterans went from under 1% of the VA caseload to approximately 15% of new presumptive claims processed in 2022–2024, according to VA data.
For burn pit exposure, you don't need to prove you stood next to a specific burn pit. You need to show you served in a covered location during the covered period. Your DD-214 and service records are usually sufficient. VA also maintains a Burn Pit Registry — if you've already registered, your record is already in the system.
For Camp Lejeune, documentation of housing records or military orders showing assignment to the base during the covered period is the primary evidence.
To get the right rating — not just approved, but correctly rated — you need the following evidence in your file:
As explained above, PFT results are the primary basis for DC 6602 ratings. Without them, your rating will default to 0%. Get current PFTs from a pulmonologist or respiratory specialist. Make sure the report includes FEV-1 as a percentage of predicted value and the FEV-1/FVC ratio. If your results improved with a bronchodilator (as often happens), the pre-bronchodilator results typically determine your rating.
VA will schedule a C&P exam to evaluate your asthma. The examiner will review your PFT results, assess your symptoms, and document functional limitations. The C&P exam report becomes part of your official rating decision. We cover C&P exam preparation in detail below.
Document all medications you take for asthma: rescue inhalers, maintenance inhalers, oral steroids, nebulizers, biologics. Frequency of use matters — daily use of a bronchodilator supports a 30% rating; use of oral corticosteroids more than three times per year supports a 50% rating. Get records of any ER visits or hospitalizations for asthma attacks.
What triggers your asthma? Exercise? Cold air? Dust? Allergens? How does it limit work, recreation, and daily activities? Buddy statements from coworkers who have witnessed asthma episodes, a written statement from you describing daily limitations, and documentation of any job accommodations or missed work due to asthma all strengthen your claim.
Need Pulmonary Documentation Support?
Getting strong asthma evidence before your C&P exam matters enormously. REE Medical connects veterans with pulmonologists and respiratory specialists experienced in VA documentation — they know how to measure and document asthma severity in the FEV-1 language that drives DC 6602 ratings.

Your C&P exam for asthma is typically conducted by a VA-contracted physician or physician assistant. Here's what happens and how to prepare:
Don't minimize your symptoms. This is the most common mistake. Veterans are stoic by nature and tend to describe asthma as "manageable" or "not that bad." The examiner is asking about your worst days and your average burden, not your best days. Describe the real impact:
Bring your PFTs to the exam. If you've already had pulmonary function testing done privately, bring the results. The C&P examiner will incorporate them into the evaluation. PFTs ordered directly by VA through the C&P process can take additional weeks — having them in hand on exam day speeds your rating decision.
Bring your medication list. Every inhaler, every oral steroid course, every nebulizer treatment. Frequency of corticosteroid use directly affects your rating — the examiner needs to document this accurately.
Processing time for initial asthma claims is typically 4–6 months. PACT Act presumptive claims have been processing somewhat faster due to VA's dedicated PACT review lanes.
Asthma can be service-connected as a secondary condition — meaning it was caused or aggravated by a primary service-connected disability. This is especially common in the following scenarios:
Psychological stress is a documented trigger for asthma and respiratory conditions. Veterans with service-connected PTSD who develop or experience worsened asthma may be able to establish a secondary connection. The nexus requires a medical opinion from a physician or psychologist linking the stress response to asthma symptom exacerbation — not always easy to establish, but achievable with the right provider.
Veterans with severe musculoskeletal conditions that limit physical activity may develop exercise-induced asthma or worsened respiratory function due to chronic inactivity. A physician can document this causal chain.
Certain medications used for service-connected conditions — including some beta-blockers used for hypertension — can trigger or worsen asthma. If a VA-prescribed medication caused your asthma to develop or worsen, this is a viable secondary claim pathway.
For all secondary claims, you need a medical nexus letter or DBQ from a physician explicitly linking the primary service-connected condition to the asthma.
The most common reason VA denies or underrates asthma claims:
This usually means no PFT results in your file. The fix: get pulmonary function tests done, then file a Supplemental Claim (VA Form 20-0995) with the new PFT results as new and relevant evidence. The supplemental claim lane is faster than other appeal options and has a strong success rate when genuine new evidence is submitted.
If VA denied service connection entirely, check whether you're eligible under the PACT Act presumptive. Many veterans denied pre-2022 are now eligible for approval under the updated burn pit and toxic exposure presumptives. File a supplemental claim citing the PACT Act and your qualifying service location.
VA sometimes denies asthma as a pre-existing condition not worsened by service. Counter this by documenting worsening during or after service with medical records, buddy statements, and a physician's opinion on aggravation.
Denied? Build a Stronger Supplemental Claim
Denied despite PACT Act eligibility? Or approved at 0% because VA didn't have your PFT results? REE Medical helps build supplemental claim packages with the clinical evidence — pulmonary function testing, DBQs, and nexus opinions — needed to overturn denials and upgrade underratings.

Yes — if your asthma has worsened since your original rating, you can file for a rating increase. The process:
A veteran was rated at 20% for asthma in 2019 based on PFTs showing FEV-1 at 73% (within the 10%–20% range at the time). By 2024, her FEV-1 had dropped to 58% with daily bronchodilator use and two courses of oral steroids per year. She filed for an increase, submitted new PFTs and treatment records, and received a rating upgrade to 50% — adding approximately $890/month in additional disability pay.
Marcus deployed to Iraq from 2008–2009 with the Army. During deployment, he was stationed near open burn pits used to dispose of waste and equipment. Within 18 months of returning home, he developed new-onset asthma — something he'd never had before service. He saw a civilian pulmonologist who confirmed the diagnosis and prescribed a daily maintenance inhaler.
In 2021, Marcus filed a VA disability claim for asthma. He was denied — VA said asthma was not proven to be related to service, citing lack of in-service treatment records. Marcus hadn't seen a doctor during deployment and had no service treatment records documenting respiratory complaints.
After the PACT Act passed in 2022, Marcus filed a supplemental claim. He cited his burn pit exposure (documented on his DD-214 showing Iraq deployment), submitted his pulmonologist's records showing the asthma onset shortly after return, and attached new PFTs showing FEV-1 at 62%. VA approved the supplemental claim under PACT Act presumptive service connection and rated him at 30% under DC 6602.
Marcus's back pay covered from his original 2021 filing date — adding up to 18 months of retroactive compensation once the supplemental claim was approved.
No — especially under PACT Act presumptive. For burn pit and toxic exposure presumptives, you only need to prove you served in a covered location. Asthma that developed or was diagnosed after service is fully eligible as long as exposure is documented and the timeline is consistent.
Yes. The VA rating is based on your lung function and medication requirements, not whether your asthma is "controlled." If you require daily bronchodilator medication, you qualify for at least a 30% rating under DC 6602 regardless of whether your symptoms are well-managed on that medication.
VA does not rate both conditions separately when they overlap — they're rated as a single respiratory condition to avoid "pyramiding" (rating the same disability twice). The rater uses DC 6602 for asthma or DC 6604 for COPD, whichever results in a higher rating. Make sure your documentation covers both conditions and all symptoms.
Yes, they can be separately rated if they are separate conditions that don't overlap in symptoms. Many veterans have both asthma and sleep apnea, and if each has its own distinct service connection, each gets its own rating. Make sure each condition has its own DBQ or medical documentation.
60% is the maximum rating for asthma under DC 6602. However, a veteran with asthma at 60% combined with other service-connected conditions can still have a combined rating of 70%, 80%, 90%, or even 100%.
