A18.4
BillableTuberculosis of skin and subcutaneous tissue
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This is a form of tuberculosis that affects the skin and the tissues just beneath the skin surface, causing lesions or sores. It occurs when the tuberculosis bacteria spreads to these outer body areas rather than staying in the lungs.
Coding Tips
- •Verify documentation specifies tuberculosis involvement of skin/subcutaneous tissue; do not use this code for other skin conditions or non-tuberculous infections
- •This code may require an additional code to identify the site of infection (e.g., face, trunk, extremity) if the documentation provides this level of specificity
Excludes 2 — Not included here, may code separately
