ICD-10 Code A15.5 – Tuberculosis of larynx, trachea and bronchus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A15.5 – Tuberculosis of larynx, trachea and bronchus
What it is
This code identifies active tuberculosis involving the larynx, trachea, or bronchus. Use it when documentation shows TB infection in these airway structures, not just pulmonary disease.
Clinical signs
Clinical features may include hoarseness, cough, airway irritation, or symptoms of endobronchial disease. Confirm the site of involvement in the record; clinical features vary; refer to documentation.
When to use this code
Use A15.5 when the provider documents tuberculosis of the larynx, trachea, or bronchus as an active diagnosis. It also applies when these airway sites are specifically identified in the assessment, imaging, bronchoscopy, or pathology notes. If the record only says pulmonary TB, do not assume this code.
Do not use for
Do not use this code for latent TB, screening, or a history of tuberculosis. If the airway site is not documented, or the note only supports lung TB without laryngeal, tracheal, or bronchial involvement, check documentation.
Coding tip
Code the most specific documented TB site and verify whether additional TB codes are needed for other involved organs.
