C7A.0 — Malignant carcinoid tumors
C7A.0 is a non-billable header ICD-10-CM code for malignant carcinoid tumors. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above C7A.0
Also inherited, and the opposite of Excludes1: these conditions are not part of C7A.0, but a patient can have both, so you may code both.
Other codes that can never be billed with C7A.0
These codes carry an Excludes1 note pointing at C7A.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C7A.0 alone.

- C18Malignant neoplasm of colon

Risk adjustment
C7A.0 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.
Code history
C7A.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
