Diagnostic Code 6822 · 38 CFR §4.97
Actinomycosis is a rare bacterial infection caused by Actinomyces species that can affect the lungs (thoracic actinomycosis). It often mimics lung cancer or tuberculosis on imaging. The infection can cause chronic lung damage, abscesses, and fibrosis. Veterans may develop this condition from dental infections spreading to the lungs or from aspiration events during service.
| Rating | Criteria |
|---|---|
| 0% | Infection fully treated with no residual pulmonary damage on imaging or PFTs. |
| 30% | Resolved infection with mild residual scarring and modest PFT impairment. Minor chronic symptoms. |
| 50% | Significant residual lung damage with moderate PFT deficits. May have chronic draining sinuses or require prolonged antibiotic courses. |
| 100% | Active disseminated disease or severe chronic pulmonary destruction causing respiratory failure. |
Biopsy or culture results confirming actinomycosis. Imaging showing pulmonary involvement. Treatment records (typically prolonged antibiotic courses). Current PFTs showing any residual impairment.
Despite sometimes being grouped with mycotic diseases, actinomycosis is actually caused by bacteria (Actinomyces). It requires prolonged antibiotic treatment rather than antifungal medications. The VA rates it separately under DC 6822.
Yes, if you can show the infection developed during service or as a result of service-related conditions such as dental problems, aspiration events, or immunosuppression from service-connected conditions.
