Question:

Histology (Pre-2007): What code is used to represent the histology "papillary adenocarcinoma: mixed serous, endometrioid and mucinous subtypes"? See discussion.

Discussion:

Example: Fallopian tube right (salpingectomy): Primary adenocarcinoma: mixed serous, endometrioid, and mucinous subtypes

Answer:

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.

History:

For cases diagnosed prior to 1/1/98: Code the Histology field to 8480/3 [mucinous adenocarcinoma] because it is the highest histology code.
