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.
