Malignant neoplasm of external upper lip

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Cancer that starts on the outer surface of the upper lip.

Coding Tips

  • •Distinguish between external (outer) lip and inner lip surfaces, as they have different codes
  • •Verify laterality (left vs. right) if documented, though this code does not require laterality specification
