Sequelae of tuberculosis (B90)

The ICD-10 code B90 and its subcodes classify the lasting effects, or sequelae, of tuberculosis after the active infection has resolved. These codes help document specific long-term conditions caused by tuberculosis in different organs and systems.

These codes specify sequelae of tuberculosis affecting various parts of the body: B90.0 covers late effects on the central nervous system, often referred to as sequelae of tuberculosis or late effects of CNS tuberculosis; B90.1 addresses sequelae in the genitourinary system, known as late effects of genitourinary tuberculosis; and B90.2 records joint and bone complications, sometimes called post-bacterial arthropathy or post-tuberculous reactive arthritis. For other organs not specifically listed, B90.8 is used. The code B90.9 pertains to respiratory and unspecified tuberculosis sequelae, including conditions such as tuberculous bronchiectasis, post-infective pleural fibrosis, and thickening of the pleura. Using these detailed ICD-10 codes ensures accurate identification of tuberculosis-related complications, improving clarity in medical records and supporting proper patient care.
