Tuberculosis of larynx, trachea and bronchus

This code represents an active tuberculous infection affecting the voice box (larynx), windpipe (trachea), and/or the larger airways leading into the lungs (bronchi). This form of tuberculosis is often secondary to pulmonary tuberculosis but can occur in isolation.

Use this code when documentation explicitly states a diagnosis of tuberculosis involving the larynx, trachea, or bronchus. This diagnosis is typically confirmed by microbiological studies (e.g., sputum culture, PCR) or histopathological examination of tissue biopsies from the affected areas.

• Differentiate from latent tuberculosis infection, which is coded elsewhere.
• Always look for documentation of the specific anatomical site(s) involved to ensure accurate coding.
• Code any associated pulmonary tuberculosis or other manifestations of tuberculosis separately, following sequencing guidelines.
