D01
D01 — Carcinoma in situ of other and unspecified digestive organs
Non-billable headerICD-10-CM
D01 is a non-billable header ICD-10-CM code for carcinoma in situ of other and unspecified digestive organs. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- melanoma in situ (D03.-)
Other codes that can never be billed with D01
These codes carry an Excludes1 note pointing at D01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D01 alone.
Risk adjustment
D01 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
