Question:

Histology (Pre-2007)--Pancreas: Is a "composite mucinous adenocarcinoma and squamous cell carcinoma" coded to 8560 [adenosquamous carcinoma] or should 8480 [mucinous adenocarcinoma] be coded rather than 8070 [squamous carcinoma] because mucinous adenocarcinoma is a higher histology code than squamous carcinoma?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Assign code 8560 [adenosquamous carcinoma]. According to our pathologist consultant, the mix of adenocarcinoma and squamous carcinoma is adenosquamous carcinoma. Adenosquamous tumors are rare, but known, representing 3-4% of pancreatic carcinomas.

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.
