Tuberculous pleurisy

This code represents inflammation of the pleura (the membranes surrounding the lungs) specifically caused by Mycobacterium tuberculosis. It is a form of extrapulmonary tuberculosis affecting the pleural space, often presenting with pleural effusion.

Use this code when documentation clearly indicates a diagnosis of pleurisy confirmed to be of tuberculous origin, typically supported by positive pleural fluid cultures, biopsy, or PCR for M. tuberculosis. This diagnosis is often made in patients presenting with chest pain, dyspnea, and a pleural effusion in the context of tuberculosis exposure or active disease.

• Ensure the documentation explicitly states "tuberculous" pleurisy; "pleurisy" alone is insufficient.
• Do not code this with A15.7 (primary respiratory tuberculosis) as per the Excludes1 note.
• Consider sequencing this code after the primary site of tuberculosis if it is a manifestation of a more widespread active disease.
