Sequelae of respiratory and unspecified tuberculosis

This code signifies the long-term, residual effects or complications arising from a past episode of respiratory or unspecified tuberculosis. These sequelae are not active tuberculosis but rather permanent changes to organ systems, such as pulmonary fibrosis, bronchiectasis, or chronic respiratory insufficiency, directly attributable to the prior infection.

Use this code when a patient presents with a chronic condition that is a direct consequence of a previously treated or resolved tuberculosis infection. Documentation should clearly link the current condition to a past history of tuberculosis, indicating that the active infection is no longer present. This code is appropriate for conditions like post-tuberculosis bronchiectasis or extensive pulmonary scarring.

• Always sequence this code after the specific manifestation of the sequela (e.g., J47.0 for bronchiectasis).
• Do not use this code if the patient has active tuberculosis; instead, use codes from categories A15-A19.
• Ensure documentation explicitly states "sequela of tuberculosis" or clearly links the current condition to a past tuberculosis diagnosis.
