Asthma VA Disability Rating
DC 6602 | 38 C.F.R. § 4.97 | M21-1, Part IV.ii.7
OVERVIEW
Asthma is rated under DC 6602 based on pulmonary function test (PFT) results, specifically FEV-1 and FEV-1/FVC ratios, or based on the frequency and type of treatment required. Veterans exposed to burn pits, sandstorms, and airborne hazards during deployments may develop asthma or constrictive bronchiolitis. The PACT Act (Public Law 117-168) established presumptive service connection for certain respiratory conditions related to toxic exposures.
RATING CRITERIA (4 LEVELS)
100% — FEV-1 less than 40% predicted, or FEV-1/FVC less than 40%
Severe airflow limitation, or more than one attack per week with episodes of respiratory failure, or requires daily use of systemic corticosteroids or immunosuppressive medications.
60% — FEV-1 of 40-55% predicted, or FEV-1/FVC of 40-55%
Moderate to severe airflow limitation, or at least monthly visits to physician for required care of exacerbations, or intermittent courses of systemic corticosteroids.
30% — FEV-1 of 56-70% predicted, or FEV-1/FVC of 56-70%
Moderate airflow limitation, or daily inhalational or oral bronchodilator therapy, or inhalational anti-inflammatory medication.
10% — FEV-1 of 71-80% predicted, or FEV-1/FVC of 71-80%
Mild airflow limitation, or intermittent inhalational or oral bronchodilator therapy.
KEY EVIDENCE TO GATHER
-Pulmonary function tests (PFTs) showing FEV-1 and FEV-1/FVC ratios
-Deployment records showing exposure to burn pits, sandstorms, or airborne hazards
-VA Airborne Hazards and Open Burn Pit Registry enrollment
-Treatment records showing inhaler prescriptions, nebulizer use, or steroid courses
-Pre-service and post-service PFTs showing decline in lung function
SECONDARY CONDITIONS (3 MAPPED)
DC 6847
Chronic airway inflammation can contribute to upper airway collapse during sleep.
DC 7346
Asthma medications (especially inhaled corticosteroids) can worsen GERD, and GERD can worsen asthma in a bidirectional relationship.
DC 9413
Chronic breathing difficulty causes anxiety and panic-like symptoms.
C&P EXAM TIPS (4)
1.PFT results are the primary rating tool — ensure you have current PFTs within the last 12 months.
2.Do NOT use your inhaler before the PFT if you want the test to reflect your baseline lung function. Discuss with your doctor.
3.If you were exposed to burn pits, register at the VA Airborne Hazards and Open Burn Pit Registry.
4.Document daily medication use — daily bronchodilator therapy supports a minimum 30% rating regardless of PFT values.
DOLLAR IMPACT
Asthma at 30% (daily inhaler use) provides $552/mo. At 60% with intermittent steroid courses, $1,432/mo. PACT Act presumptives make this condition significantly easier to service-connect for post-9/11 veterans.
