Tuberculosis (A15-A19)
ICD-10 codes A15-A19 classify various types of tuberculosis infections, targeting the respiratory system, nervous system, other organs, and miliary forms that spread throughout the body. These codes help specify the location and nature of the tuberculosis infection for accurate diagnosis and treatment.
The range begins with A15 codes for respiratory tuberculosis, including pulmonary tuberculosis (often called inactive tuberculosis or pulmonary tuberculosis) and tuberculosis affecting the lungs, lymph nodes, larynx, pleura, and other parts of the respiratory tract. For example, A15.0 covers tuberculosis of the lung, while A15.4 represents tuberculosis of intrathoracic lymph nodes, such as tuberculous adenitis. The A17 section classifies tuberculosis of the nervous system, including tuberculous meningitis (A17.0) and tuberculomas of brain and spinal cord (A17.81). Codes under A18 describe tuberculosis affecting other organs like bones and joints (including Pott's disease at A18.01), the genitourinary system, intestines, skin (lupus vulgaris at A18.4), eyes, ears, adrenal glands, thyroid, heart, spleen, and more. Finally, the A19 codes cover miliary tuberculosis, a form of disseminated tuberculosis that can affect multiple or unspecified sites in the body. Using synonyms like disseminated tuberculosis or extrapulmonary tuberculosis alongside specific codes helps clinicians and coders accurately pinpoint the disease location and type for proper patient management.

Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- infections due to Mycobacterium tuberculosis and Mycobacterium bovis
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- congenital tuberculosis P37.0
- nonspecific reaction to test for tuberculosis without active tuberculosis R76.1
- pneumoconiosis associated with tuberculosis, any type in A15 J65
- positive PPD R76.11
- positive tuberculin skin test without active tuberculosis R76.11
- sequelae of tuberculosis B90
- silicotuberculosis J65
