Diagnostic Code 6703 · 38 CFR §4.97
This diagnostic code covers chronic pulmonary tuberculosis classified as active minimal. While active TB is rare in modern military service, it can occur in veterans who served in areas with high TB prevalence (Southeast Asia, Africa, Eastern Europe) or in confined settings like submarines and prisons. The VA assigns a total rating during active disease and for a mandatory period after stabilization, then rates based on residual lung damage.
| Rating | Criteria |
|---|---|
| 100% | Active pulmonary tuberculosis confirmed by sputum culture, imaging, or clinical findings. During the active disease phase and for a specified period following stabilization, a total (100%) rating applies. |
| 50% | Following the mandatory total rating period for active TB, the rating may step down based on residual impairment if the disease is determined to be inactive. Residual damage rated on pulmonary function. |
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.
