Answer:
For tumors diagnosed prior to 2007:
Code histology to 8255 [Adenocarcinoma with mixed subtypes]. ICD-O-3 does not have a code specific to this combination histology. 8255 is the best code available.
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.
