D3A.00 — Benign carcinoid tumor of unspecified site
Is D3A.00 billable?
Yes, but D3A.00 is an unspecified code. D3A.00 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D3A.00 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting D3A.00 — the more specific alternatives are listed below.

Use additional code — inherited from D3A
Report an additional code alongside D3A.00 to fully describe the condition. D3A.00 is sequenced first.
- code to identify any associated endocrine syndrome, such as:
- carcinoid syndrome (E34.00)
Excludes2 — not included here — inherited from D3A
The conditions below are not part of D3A.00, but a patient may have both at the same time. When documentation supports it, D3A.00 and the excluded code may both be reported.
- benign pancreatic islet cell tumors (D13.7)
Code also — inherited from D3A
Two codes may be needed to describe the condition fully. Whether D3A.00 is sequenced first depends on the reason for the encounter.
- any associated multiple endocrine neoplasia [MEN] syndromes (E31.2-)
