Pulmonary Tuberculosis: How VA Rates Active & Inactive TB Under 38 CFR 4.97

Active tuberculosis of the respiratory system is evaluated under Diagnostic Code 6731 in 38 CFR 4.97. When active disease is confirmed by positive sputum culture, molecular testing, or clinical diagnosis requiring intensive anti-mycobacterial drug therapy, the VA assigns a mandatory 100% disability rating under 38 CFR 4.88b. This total disability rating continues for the entire duration of active infection and clinical treatment.

Under 38 CFR 4.88c, when pulmonary tuberculosis is determined to be inactive (disease arrest achieved following completion of therapy), the 100% evaluation continues without reduction for a full one-year period from the date of inactivity. This statutory floor protects recovering veterans as they regain lung capacity and general physical health, prohibiting any premature rating reduction during the initial year of remission.

Following the expiration of the one-year post-inactivity window, the veteran is re-evaluated under Diagnostic Code 6730 (chronic pulmonary tuberculosis, inactive). The evaluation is based on permanent structural and functional pulmonary residuals: severe lung volume loss, extensive fibrocalcific scarring, cavitary lesions, thoracoplasty surgical collapse, or lobectomy. Residuals are rated using the objective pulmonary function test criteria for restrictive or obstructive disease in 38 CFR 4.97.

For veterans whose service connection for inactive tuberculosis was established prior to August 19, 1968, 38 CFR 4.89 provides exceptional graduated statutory floors: a 100% rating for two years following inactivity, followed by a 50% rating for the subsequent four years, and a permanent 30% rating for the next five years. While this applies only to a closed historical veteran population, modern adjudicators must recognize and preserve these protected grandfathered statutory evaluations.

Tuberculosis possesses special presumptive status under 38 CFR 3.309(a). Active tuberculosis that manifests to a compensable degree (10% or greater) within three years from the date of military separation is presumed to be service-connected, even if no symptoms were noted in military service treatment records. This extended three-year presumptive window recognizes the slow incubation and latent reactivation of Mycobacterium tuberculosis infections contracted during military service.
