C7A
Header — not billableMalignant neuroendocrine tumors
The ICD-10 code for malignant neuroendocrine tumors is C7A.
C7A is a non-billable header code. It groups related conditions but cannot be used on its own for reimbursement — select one of the 3 more specific codes below.
Clinical notes
Code also
Two codes may be needed to fully describe a condition, but unlike Code First/Use Additional Code, the sequencing order is not mandated by convention.
- any associated multiple endocrine neoplasia [MEN] syndromes (E31.2-)
Excludes2 (not included here)
An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.
Use additional code
This code represents an underlying condition. When a related manifestation is also present, coding convention calls for an additional code to be listed after this one.
- code to identify any associated endocrine syndrome, such as:
- carcinoid syndrome (E34.00)
Documentation support
General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.
- •This is a non-billable header code. Documentation must support a more specific child code before this diagnosis can be reported on a claim.
- •If the associated manifestation or related condition noted above is also documented, an additional code should be reported alongside this one.
- •As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
