Question 20200080
Inquiry Details
References:
ICD-O-3.2
Question:
Reportability/Histology--Pancreas: Is a diagnosis of insulin-producing (insulinoma) epithelioid neoplasm reportable if made 2021 and later? If so, is the histology coded as 8151/3 per the ICD-O-3.2 Coding Table? See Discussion.
Discussion:
The ICD-O-3.2 Implementation Guidelines and ICD-O-3.2 Coding Table indicate that insulinoma, NOS has changed behavior from /0 to /3 for cases diagnosed 2021 and later. However, the ICD-O-3.2 Implementation Guidelines do not indicate whether this change applies to tumors described as above. Insulinomas are generally neuroendocrine tumors/neoplasms, so it seems any neuroendocrine tumor described as an insulinoma should be collected as 8151/3, but does that apply to an epithelioid tumor/neoplasm also described as insulinoma?
This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales.
Answer:
If the diagnosis includes insulinoma, it is reportable and coded 8151/3. Insulin-producing epithelioid neoplasm alone, without mention of insulinoma, is not reportable.
