LOADING
Respiratory Condition / Sinusitis VA Disability Rating is rated by the U.S. Department of Veterans Affairs under DC 6510-6514 of 38 C.F.R. § 4.97 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.
Chronic sinusitis (DC 6510-6514) rates from 0-50%. 10% for one or two incapacitating episodes per year requiring prolonged antibiotic treatment. 50% following radical surgery with chronic osteomyelitis or near constant sinusitis with frequent headaches and purulent discharge.
Respiratory Condition / Sinusitis (DC 6510-6514) is evaluated under 38 C.F.R. § 4.97 using the respiratory rating framework. Because it is rated by analogy to the general schedule, the 4 levels below describe the body-system criteria the VA applies — the percentage assigned to Respiratory Condition / Sinusitis depends on the specific findings (range of motion, frequency, severity, or functional loss) documented at the C&P exam and in the medical record.
Rating criteria reference 38 C.F.R. Part 4 (Schedule for Rating Disabilities). This entry has not yet undergone editorial review against the live regulation text — consult the authoritative source directly before relying on the criteria shown.
