C44.82
BillableSquamous cell carcinoma of overlapping sites of skin
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This is a type of skin cancer (squamous cell carcinoma) that starts in the flat cells on the surface of the skin and involves two or more adjacent areas of the skin. It is one of the most common types of skin cancer and is often caused by sun exposure.
Coding Tips
- •When squamous cell carcinoma affects multiple adjacent skin sites, use this code rather than coding each site separately; ensure documentation specifies the overlapping nature of the lesion
- •This code requires a fifth character to specify the anatomical site (e.g., C44.821 for eyelid, C44.829 for unspecified overlapping sites); always verify the exact location documented by the provider
