C44.40
BillableUnspecified malignant neoplasm of skin of scalp and neck
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code represents a cancer of the skin on the scalp or neck area where the specific type of skin cancer has not been identified or documented. It is used when a malignant (cancerous) skin tumor is confirmed but the histological subtype (such as melanoma or carcinoma) is not specified.
Coding Tips
- •Do not use this code if the specific type of skin cancer is documented (e.g., melanoma, basal cell carcinoma, squamous cell carcinoma) - use the more specific subtype code instead
- •Verify documentation specifies the location as scalp and/or neck; if the cancer is on a different body part, select the appropriate anatomical site code from the C44 category
