Billable

Carcinoma in situ of oral cavity, unspecified site

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

What This Code Means

Abnormal cells in the mouth that have the potential to become cancer but are not yet invasive, at an unspecified location in the oral cavity.

Coding Tips

  • •This is a pre-cancerous condition (carcinoma in situ), not invasive cancer
  • •If the specific site in the oral cavity is documented, use a more specific D00.0x code rather than the unspecified code
