2025 ICD-10-CM code A15.9
(Active) Effective Date: N/A Certain infectious and parasitic diseases - Tuberculosis 1 Feed
Respiratory tuberculosis, unspecified.
Medical necessity for the diagnosis and treatment of tuberculosis is established by the confirmation of active disease, which poses a significant threat to the patient's health and has the potential for public health transmission.
Clinicians diagnose respiratory tuberculosis based on symptoms (cough, fever, weight loss, night sweats), physical exam, imaging (chest x-ray, CT scan), and laboratory tests (sputum culture, molecular tests). Treatment typically involves a multi-drug regimen.
In simple words: This code indicates that a person has tuberculosis (TB) affecting the respiratory system, but the specific location within the respiratory system isn't specified in the medical record.The diagnosis has been confirmed through lab tests, molecular tests or tissue samples.
This code signifies a diagnosis of respiratory tuberculosis where the specific site or type is not documented or unspecified.It is confirmed bacteriologically, molecularly, or histologically.
Example 1: A patient presents with a persistent cough, fever, and weight loss. Sputum culture confirms Mycobacterium tuberculosis, but the specific site of infection in the respiratory system is not identified. A15.9 is used., A patient with HIV undergoes bronchoscopy which reveals granulomas suggestive of tuberculosis. Molecular testing confirms the presence of Mycobacterium tuberculosis DNA.In the absence of a more specific site, A15.9 is assigned., A patient presents with respiratory symptoms. Histological examination of a lung biopsy reveals caseating granulomas consistent with tuberculosis. If the specific site isn't further defined, A15.9 is applicable.
Documentation should include evidence of diagnostic confirmation (bacteriological, molecular, or histological) of Mycobacterium tuberculosis in the respiratory tract. Clinical findings, imaging results, and treatment details should also be documented.
