A15.7
BillablePrimary respiratory tuberculosis
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This is tuberculosis that first develops in the lungs and respiratory system, typically occurring when someone is initially infected with the tuberculosis bacteria. It represents the primary infection site rather than a reactivation of old tuberculosis.
Coding Tips
- •Verify documentation specifies this is primary TB (initial infection) rather than reactivation TB, as this distinction affects treatment and prognosis coding
- •Ensure the site is confirmed as respiratory/pulmonary; if TB has spread to other organs, use additional codes for extrapulmonary manifestations
