Not billable
Is C80 billable?
No — C80 is a non-billable header code. C80 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 3 billable codes beneath C80.

Excludes1 — never code together
The conditions below can never be reported together with C80 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- malignant carcinoid tumor of unspecified site (C7A.00)
- malignant neoplasm of specified multiple sites- code to each site
