Squamous cell carcinoma of skin of right ear and external auricular canal

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

What This Code Means

Squamous cell carcinoma, a common type of skin cancer, occurring specifically on the right ear or external ear canal.

  • •Confirm right ear laterality is documented; squamous cell carcinoma has a higher risk of metastasis than basal cell carcinoma.
  • •Document depth of invasion and grade if available, as these factors influence treatment decisions and prognosis.
