How the VA Rates Asthma

The VA rates bronchial asthma under Diagnostic Code 6602 (38 CFR §4.97, Schedule of Ratings: Respiratory System). Ratings run from 10% to 100% based on pulmonary function test (PFT) results, specifically FEV-1 (forced expiratory volume in one second) and the FEV-1/FVC ratio, and the level of medication required to control symptoms.

Diagnostic Code 6602: Rating Criteria

The VA assigns whichever criterion (the PFT result or the medication requirement) produces the higher rating.

Asthma and the PACT Act

Asthma is one of the respiratory conditions covered by the PACT Act's presumptive list for veterans with qualifying airborne hazard and burn pit exposure during covered periods and locations (including Gulf War era and post-9/11 service). If you served in a covered location, you do not need to separately prove that your service caused your asthma; the presumption does that for you, though you still need a current diagnosis and, in most cases, a qualifying service period.

Evidence: Pulmonary Function Tests

PFT results are the central evidence in an asthma claim. Bring your most recent spirometry results (FEV-1, FEV-1/FVC, and whether post-bronchodilator results were used) to your C&P exam, or request a current PFT from your pulmonologist or primary care provider before filing if your last test is old. The VA rates on the test result that most accurately reflects your disability. If pre- and post-bronchodilator results differ, the VA generally uses whichever is more favorable to the higher rating, per the regulation's own instructions to the rater.

What to Expect at Your C&P Exam

2026 Monthly Compensation Amounts

A 10% VA rating for asthma pays $180.42 per month (2026 rate, veteran alone, no dependents). A 30% rating pays $552.47/month, a 60% rating pays $1,435.02/month, and a 100% rating pays $3,938.58/month. Rates increase with dependents at 30% and above; see the full 2026 VA compensation rate chart.

Secondary conditions to asthma

Asthma frequently travels with other conditions that veterans can also claim on a secondary basis, and the C&P exam even asks about several of them directly.

GERD (acid reflux). Acid reflux and asthma have a well-documented bidirectional relationship — reflux can trigger or worsen asthma symptoms, and asthma coughing or medications can worsen reflux in turn. When a physician's opinion documents this connection, GERD secondary to asthma (or asthma secondary to GERD) is one of the more commonly supported secondary claims for veterans with a respiratory rating.

Allergic rhinitis and sinusitis. Asthma and upper-airway allergic conditions are closely linked, and chronic allergic rhinitis or sinusitis frequently coexists with, or is aggravated by, asthma.

Sleep apnea. Long-term corticosteroid use for asthma can contribute to weight gain, a recognized risk factor for obstructive sleep apnea, giving some veterans a secondary pathway between the two.

Anxiety and depression. Living with a chronic respiratory condition that limits exertion and requires ongoing medication management can trigger or worsen anxiety and depression; a nexus opinion linking the two supports a secondary claim.
