Asthma

Asthma is rated under 38 CFR § 4.97, Diagnostic Code 6602. The VA evaluates FEV-1 and FVC pulmonary function test results, frequency of attacks, and how often you require systemic corticosteroids.

VA Rating Levels

10%

FEV-1 of 71–80% predicted, or FVC of 71–80% predicted, or at least one attack per year requiring systemic corticosteroids.

30%

FEV-1 of 56–70% predicted, or FVC of 56–70%, or 1–4 attacks per year requiring systemic corticosteroids.

60%

FEV-1 of 40–55%, or FVC of 40–55%, or more than 5 attacks per year requiring systemic corticosteroids, or daily oral corticosteroid use.

100%

FEV-1 less than 40% predicted, or FVC less than 40%, or chronic bronchospasm requiring daily systemic corticosteroids or immunosuppressive medications.

Exam Tips & Key Evidence

  • Pulmonary function testing (spirometry) is essential — make sure your C&P exam includes it
  • Burn pit exposure is a common service nexus for asthma — file under PACT Act if applicable
  • Albuterol use alone is not enough if FEV-1 is normal — document attack frequency
  • Asthma worsened by GERD is secondary to GERD condition if service-connected
