D00.03
BillableCarcinoma in situ of gingiva and edentulous alveolar ridge
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes abnormal cells found in the gums or the ridge of bone where teeth are missing that have the potential to become cancer if not treated. These cells are confined to the surface layer and have not yet invaded deeper tissues.
Coding Tips
- •Verify documentation specifies the location as gingiva (gums) or edentulous alveolar ridge (toothless jaw bone area) to ensure correct code selection
- •Confirm this is carcinoma in situ (pre-cancerous/non-invasive) and not invasive carcinoma, as invasive cases require different coding
