ICD-10 Code A15.6 – Tuberculous pleurisy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A15.6 – Tuberculous pleurisy
What it is
A15.6 identifies pleural tuberculosis, meaning Mycobacterium tuberculosis infection involving the pleura. Use it when the record clearly documents tuberculous pleurisy or pleural TB.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include pleuritic chest pain, cough, and pleural effusion, but the diagnosis should be supported by the provider’s statement or confirmed TB evidence.
When to use this code
Use A15.6 when the clinician documents tuberculous pleurisy, pleural tuberculosis, or TB affecting the pleura. It may also apply when pleural involvement is the stated active site of tuberculosis. If the chart only says “pleural effusion” without TB, do not assume this code.
Do not use for
Do not use this code for nonspecific pleurisy, bacterial pleural infection, or pleural effusion of another cause. Check documentation if tuberculosis is not explicitly linked to the pleura.
Coding tip
Code A15.6 only when the record ties tuberculosis to pleural disease; otherwise, query or choose the documented alternative.
