A veteran whose spirometry looks fine can still hold a 30 percent asthma rating, because the criteria are written in the alternative: the lung number or the medication standard, whichever produces more. A daily controller inhaler by itself meets the 30 percent line, and three or more courses of oral steroids a year reaches 60. The claim often lives in the pharmacy record, not the breathing test.
How VA rates asthma
Bronchial asthma is rated under diagnostic code 6602 in the respiratory schedule (38 CFR 4.97). The rating turns on two things measured together: your pulmonary function test numbers and how much medication it takes to control the disease. VA uses whichever of the two produces the higher evaluation.
The percentage levels
- 10 percent: FEV-1 of 71 to 80 percent predicted, or the ratio of FEV-1 to FVC of 71 to 80 percent, or intermittent inhalational or oral bronchodilator therapy.
- 30 percent: FEV-1 of 56 to 70 percent, or the FEV-1 to FVC ratio of 56 to 70 percent, or daily inhalational or oral bronchodilator therapy, or inhalational anti-inflammatory medication.
- 60 percent: FEV-1 of 40 to 55 percent, or the ratio of 40 to 55 percent, or at least monthly visits to a provider for required care of exacerbations, or intermittent (at least three per year) courses of systemic (oral or parenteral) corticosteroids.
- 100 percent: FEV-1 less than 40 percent, or the ratio less than 40 percent, or more than one attack per week with episodes of respiratory failure, or daily use of high dose systemic corticosteroids or immuno-suppressive medications.
The medication rule is the quiet path to 30 percent
This is the part veterans miss most. You do not need a low FEV-1 to reach 30 percent. Daily inhalational or oral bronchodilator therapy, or inhalational anti-inflammatory medication, each independently meets the 30 percent medication standard on its own. A veteran on a daily oral bronchodilator qualifies just as a veteran on a daily inhaler does. A veteran whose breathing tests look reasonable on a calm day can still rate 30 percent, because the criteria are written in the alternative: meet the lung number or meet the medication standard, and the higher result governs.
Make sure the test is done right
The rating relies on post-bronchodilator FEV-1 numbers, and the exam should record which medications you take and how often. If the pulmonary function test was done on a good day, or a daily controller inhaler is not written into the record, the rating can land below where the medication standard would put it.
Asthma and burn pit exposure
The PACT Act made asthma a presumptive condition for veterans who served around airborne hazards and burn pits, when it was diagnosed within the regulatory window after service. For a qualifying veteran, that presumption supplies the connection without a separate nexus opinion.
The nuances most veterans miss
- Daily inhalational or oral bronchodilator therapy alone meets 30 percent, even when the breathing tests look fair. Both the inhaled and oral daily routes satisfy the medication standard independently.
- VA uses the higher of the lung number or the medication standard, so both belong in the record.
- Systemic corticosteroid courses push the rating up, so document how often oral steroids are used for flares.
- Asthma can be PACT Act presumptive for burn pit and airborne hazard exposure within the regulatory window.
- The test must be post-bronchodilator and recorded properly, because a single good-day reading can understate the disease.
