Diagnostic Code 6732 · 38 CFR §4.97
This diagnostic code covers chronic pulmonary tuberculosis classified as inactive with advancement unspecified. Inactive TB means the infection is no longer actively replicating, but residual lung damage (scarring, cavities, fibrosis) may cause permanent impairment. The VA provides a graduated rating schedule following the mandatory total rating period for previously active TB, eventually rating based solely on residual lung damage.
| Rating | Criteria |
|---|---|
| 50% | Inactive TB with significant residual pulmonary impairment. Substantial fibrosis or cavitary disease visible on imaging with meaningful PFT deficits. Applies during the graduated rating period following the mandatory total rating. |
| 30% | Inactive TB with moderate residual impairment. Some fibrotic changes with mild PFT reduction. May apply after the graduated step-down period. |
| 0% | Inactive TB with no residual pulmonary impairment. Disease fully arrested with normal PFTs and stable imaging. |
Sputum cultures or other microbiological evidence of TB (active cases). Chest imaging showing TB-related changes (cavities, fibrosis, calcifications). PFTs documenting residual impairment. Treatment records showing completed anti-TB regimen. Documentation of service in TB-endemic areas or close-contact exposure.
TB has a unique graduated rating schedule. Active TB receives a mandatory 100% rating that continues for a specified period after the disease is determined inactive. The rating then steps down gradually based on residual damage. This graduated approach is different from other respiratory conditions that are rated solely on current PFT results.
While uncommon, TB exposure can occur during deployments to regions with high prevalence (parts of Africa, Asia, Eastern Europe) or in confined military settings. Some veterans are diagnosed with latent TB that reactivates years later. The VA recognizes these service connections.
