Short answer · Medically reviewed summary · Last updated: 2026-05-08
Tuberculosis is primarily classified under ICD-10 code A15 for respiratory tuberculosis, while the legacy ICD-9 system designated it under codes 010 through 018 depending on the site of infection. Because Tuberculosis is a complex infectious disease, these codes help healthcare providers and public health agencies accurately track the global prevalence and clinical management of the condition. What are the primary ICD-10 and ICD-9 codes for Tuberculosis? In the current ICD-10 clinical modification, Tuberculosis is categorized under the "A15" series, which covers respiratory Tuberculosis confirmed by bacteriological or histological examination.

Tuberculosis is primarily classified under ICD-10 code A15 for respiratory tuberculosis, while the legacy ICD-9 system designated it under codes 010 through 018 depending on the site of infection. Because Tuberculosis is a complex infectious disease, these codes help healthcare providers and public health agencies accurately track the global prevalence and clinical management of the condition.
What are the primary ICD-10 and ICD-9 codes for Tuberculosis?
In the current ICD-10 clinical modification, Tuberculosis is categorized under the "A15" series, which covers respiratory Tuberculosis confirmed by bacteriological or histological examination. ICD-9 codes, which are still occasionally referenced in older medical records, utilized a broader range (010-018) to distinguish between pulmonary, central nervous system, and other organ-specific forms of Tuberculosis. Proper coding is essential for ensuring that patients receive the correct insurance coverage and that public health surveillance data remains accurate.
How is Tuberculosis classified medically?
Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis. Clinicians use specific diagnostic criteria to differentiate between latent Tuberculosis infection and active Tuberculosis disease. The following list outlines the key clinical distinctions often noted in medical charts:
- Latent TB: The bacteria are present but inactive, and the patient is not contagious (ICD-10 code R76.11).
- Active Pulmonary TB: The most common form, characterized by chronic cough, weight loss, and night sweats (ICD-10 code A15.0).
- Extrapulmonary TB: Infection occurring outside the lungs, such as in the lymph nodes, bones, or meninges (ICD-10 codes A17-A19).
