Question:

Histology (Pre-2007)/Behavior Code: What code is used to represent the histology "foci of well differentiated intramucosal carcinoma [carcinoma in situ] arising on the surface of a tubular adenoma"? The pathologist referred to this colon biopsy as "in situ".

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Assign histology code 8210 [adenocarcinoma in a tubular adenoma] and behavior code 2 [in situ]. "In situ" is specified by the pathologist.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
