What Raters Look For
Based on M21-1 adjudication criteria for Respiratory conditions. These are the factors a VA rater evaluates when assigning a rating percentage.
M21-1 III.iv.4.B- •Pulmonary function test results: FEV1 (% of predicted), FVC, FEV1/FVC ratio, and DLCO
- •Exercise tolerance in METs (metabolic equivalents) if cardiac limitation is also relevant
- •Frequency of exacerbations requiring medical visits, oral steroids, or hospitalization
- •Oxygen therapy use — whether prescribed and under what conditions
- •Sleep study results and AHI score if sleep apnea is claimed
- •Medication regimen: inhalers, systemic steroids, biologics
- •Smoking history (noted but not used to reduce rating)
