Understand what the VA looks for at each rating level — loading conditions…
A group of lung diseases that block airflow and make it hard to breathe, including emphysema and chronic bronchitis. The VA rates COPD based on lung function tests (FEV-1, FEV-1/FVC, or DLCO) measuring how well your lungs work.
The VA rates this condition based on objective clinical measurements and test results. The examiner will use standardized tests or lab values to determine the severity of your condition rather than relying primarily on subjective symptom reports.

Rating criteria are defined in 38 CFR 4.97, DC 6604. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.
Your lung function tests show FEV-1 less than 40 percent predicted, or FEV-1/FVC less than 40 percent, or DLCO (SB) less than 40 percent predicted, or maximum oxygen consumption less than 15 ml/kg/min (with cardiorespiratory limit), or cor pulmonale (right heart failure), or right ventricular hypertrophy, or pulmonary hypertension, or you need outpatient oxygen therapy.
