C7A.0 — Malignant carcinoid tumors
Is C7A.0 billable?
No — C7A.0 is a non-billable header code. C7A.0 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 21 billable codes beneath C7A.0.

Use additional code — inherited from C7A
Report an additional code alongside C7A.0 to fully describe the condition. C7A.0 is sequenced first.
- code to identify any associated endocrine syndrome, such as:
- carcinoid syndrome (E34.00)
Excludes2 — not included here — inherited from C7A
The conditions below are not part of C7A.0, but a patient may have both at the same time. When documentation supports it, C7A.0 and the excluded code may both be reported.
Code also — inherited from C7A
Two codes may be needed to describe the condition fully. Whether C7A.0 is sequenced first depends on the reason for the encounter.
- any associated multiple endocrine neoplasia [MEN] syndromes (E31.2-)
