Burn Pit Exposure Residuals is rated by the U.S. Department of Veterans Affairs under DC 6699 of 38 CFR § 3.320 across 4 severity tiers (100% -- FEV-1 <40% predicted / 60% -- FEV-1 40-55% / 30% -- FEV-1 56-70% / 10% -- FEV-1 71-80%). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303. This condition is frequently rated as secondary to Chronic Bronchitis or COPD under 38 C.F.R. § 3.310.
