Tuberculosis Infections – ICD 10 Codes & ICD 11 Codes

A disease caused by an infection with bacteria of the Mycobacterium tuberculosis complex. This disease presents with symptoms depending on the site of infection. Transmission is commonly by inhalation of infected respiratory secretions.

Tuberculosis Of The Respiratory System

Definition of Tuberculosis of the respiratory system: This is a progressive or chronic disease resulting from infection with the bacterium Mycobacterium tuberculosis or those in the M. tuberculosis complex: M. bovis, M. africanum, M. canetti, and M. microti. The infection is limited to the respiratory system.
