This reference uses VA rating codes. For a code from a medical record, check ICD-10-CM and the service date. A clinical code alone does not establish a VA rating or a matching VA diagnostic code.
Nontuberculosis mycobacterium infection
Infectious diseases, immune disorders and nutritional deficiencies · 38 CFR § 4.88b
Diagnostic Code 6312 is the VASRD entry for Nontuberculosis mycobacterium infection. VA applies the controlling criteria, shared formulas, and special instructions shown in 38 CFR Part 4. VMC presents this material for education and reference; it does not determine a Veteran's diagnosis, service connection, or evaluation.

Source-verified VASRD criteria
How VA rates this — Inactive nonpulmonary tuberculosis — protected August 19, 1968 cases
These percentages summarize the regulatory criteria already mapped to this diagnostic code. They do not predict a Veteran's individual evaluation or establish service connection.
For 2 years after date of inactivity, following active tuberculosis, which was clinically identified during service or subsequently
Thereafter, for 4 years, or in any event, to 6 years after date of inactivity
Thereafter, for 5 years, or to 11 years after date of inactivity
Thereafter, in the absence of a schedular compensable permanent residual
Special rating instructions
- Note 1: Continue the rating of 100 percent for the duration of treatment for active disease followed by a mandatory VA exam. If there is no relapse, rate on residuals. Any change in evaluation based upon that or any subsequent examination shall be subject to the provisions of § 3.105(e) of this chapter. Note 2: Confirm the recurrence of active infection by culture, histopathology, or other diagnostic laboratory testing. Note 3: Rate under the appropriate body system any residual disability of infection which includes, but is not limited to, skin conditions and conditions of the respiratory, central nervous, musculoskeletal, ocular, gastrointestinal, and genitourinary systems and those residuals listed in § 4.88c.
- Note 1: Continue the rating of 100 percent for the duration of treatment for active disease followed by a mandatory VA exam. If there is no relapse, rate on residuals. Any change in evaluation based upon that or any subsequent examination shall be subject to the provisions of § 3.105(e) of this chapter. Note 2: Confirm the recurrence of active infection by culture, histopathology, or other diagnostic laboratory testing. Note 3: Rate under the appropriate body system any residual disability of infection which includes, but is not limited to, skin conditions and conditions of the respiratory, central nervous, musculoskeletal, ocular, gastrointestinal, and genitourinary systems and those residuals listed in § 4.88c.
- Thereafter: Rate residuals under the specific body system or systems affected.
- Following the total rating for the 1 year period after date of inactivity, the schedular evaluation for residuals of nonpulmonary tuberculosis, i.e. , ankylosis, surgical removal of a part, etc., will be assigned under the appropriate diagnostic code for the residual preceded by the diagnostic code for tuberculosis of the body part affected. For example, tuberculosis of the hip joint with residual ankylosis would be coded 5001-5250. Where there are existing residuals of pulmonary and nonpulmonary conditions, the evaluations for residual separate functional impairment may be combined.
- Where there are existing pulmonary and nonpulmonary conditions, the total rating for the 1 year, after attainment of inactivity, may not be applied to both conditions during the same period. However, the total rating during the 1-year period for the pulmonary or for the nonpulmonary condition will be utilized, combined with evaluation for residuals of the condition not covered by the 1-year total evaluation, so as to allow any additional benefit provided during such period.
- Following the total rating for the 2-year period after date of inactivity, the schedular evaluation for residuals of nonpulmonary tuberculosis, i.e. , ankylosis, surgical removal of a part, etc., if in excess of 50 percent or 30 percent will be assigned under the appropriate diagnostic code for the specific residual preceded by the diagnostic code for tuberculosis of the body part affected. For example, tuberculosis of the hipjoint with residual ankylosis would be coded 5001-5250.
- The graduated ratings for nonpulmonary tuberculosis will not be combined with residuals of nonpulmonary tuberculosis unless the graduated rating and the rating for residual disability cover separate functional losses, e.g., graduated ratings for tuberculosis of the kidney and residuals of tuberculosis of the spine. Where there are existing pulmonary and nonpulmonary conditions, the graduated evaluation for the pulmonary, or for the nonpulmonary, condition will be utilized, combined with evaluations for residuals of the condition not covered by the graduated evaluation utilized, so as to provide the higher evaluation over such period.
- The ending dates of all graduated ratings of nonpulmonary tuberculosis will be controlled by the date of attainment of inactivity.
- These ratings are applicable only to veterans with nonpulmonary tuberculosis active on or after October 10, 1949.

Evidence information
When reviewing the criteria, useful evidence categories can include diagnosis and treatment records, objective testing identified by the schedule, documented frequency/duration/severity when the criteria use those concepts, and functional effects described in medical or lay evidence. The relevant evidence depends on the actual claim and medical facts.
VMC does not diagnose conditions, guarantee a percentage, or advise anyone to exaggerate symptoms.
