In simple words: This code indicates a type of tuberculosis that affects the respiratory system, but is not described by other, more specific tuberculosis codes.It can include TB of the mediastinum (the area separating the lungs), the nose, throat, or sinuses.

This code encompasses other forms of respiratory tuberculosis not specifically classified elsewhere, including mediastinal tuberculosis, nasopharyngeal tuberculosis, tuberculosis of the nose, and tuberculosis of any nasal sinus.

Example 1: A patient presents with cough, fever, and night sweats.A chest X-ray reveals lesions in the mediastinum, and sputum culture confirms Mycobacterium tuberculosis.The patient is diagnosed with mediastinal tuberculosis., A patient with a history of tuberculosis develops persistent nasal congestion and discharge.Examination reveals granulomas in the nasal passages, and biopsy confirms tuberculosis of the nose. , A patient experiences chronic sinusitis unresponsive to conventional treatment.A CT scan shows sinus opacification, and tissue sampling identifies Mycobacterium tuberculosis, indicating tuberculosis of the sinus.

Documentation should specify the type and site of respiratory tuberculosis, such as "mediastinal tuberculosis," "tuberculosis of nose," or "tuberculosis of sinus."
