A15.9

What This Code Means

This code describes tuberculosis that affects the lungs or respiratory system, but the specific type or location within the respiratory tract has not been clearly documented. It is used when a patient has confirmed TB of the lungs without more detailed information about which part is affected.

Coding Tips

• •Use this code only when the documentation confirms respiratory TB but lacks specificity; if more detail is available (such as TB of the lung, bronchus, or trachea), use a more specific code from the A15 category
• •Ensure the patient has confirmed tuberculosis diagnosis and that the infection site is documented as respiratory; this code requires confirmation of TB status and should not be used for suspected or ruled-out cases
