Personal history of tuberculosis

This code indicates that a patient has a documented history of having tuberculosis (TB) in the past, and the active infection has been successfully treated and resolved. It signifies that the patient is no longer experiencing active TB disease but has a prior diagnosis of the condition.

Apply this code when a patient presents for follow-up care, screening, or treatment for other conditions, and their medical record clearly indicates a past diagnosis and successful treatment of tuberculosis. It is used to document a significant past medical history that may influence current health status or treatment decisions.

• Do not use this code for active tuberculosis; use codes from Chapter 1 (A15-A19) for current infections.
• Ensure documentation specifies "personal history of" and not just "exposure to" TB.
• This code can be used as a secondary diagnosis to provide context for other presenting conditions.
