For tumors diagnosed prior to 2007:
For cases diagnosed on or after 1/1/98: Code the Histology field to 8323/3 [adenocarcinoma, mixed cell]. The case is coded using the mixed histology rule A in the Coding Complex Morph Dx's.
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.
