Question:

Reportability/Histology--Liver: Are primary hepatic neuroendocrine neoplasm and primary hepatic neuroendocrine tumor (PHNET) reportable? What are the specific histology codes?

Discussion:

Answer:

Primary hepatic neuroendocrine tumor (PHNET) is reportable as are other digestive system NETs. There is no specific histology code for PHNET. We suggest you assign 8240/3. Use text fields to document the details.

Unless you can obtain clarification, do not report primary hepatic neuroendocrine neoplasm with no further information. If this term is being used as a synonym for PHNET, document this in the registry's policies and procedures, and report these cases.
