Question:

Primary Site/Histology (Pre-2007): What codes are used to represent site and histology for BSO specimen with a diagnosis, "Left and right adnexa: poorly differentiated serous carcinoma. Comment: The carcinoma occurs as multiple nodules within adnexal soft tissues. Direct involvement of ovaries is not seen, supporting an extraovarian origin." See discussion.

Discussion:

Per our pathologist consultant, the site should be pelvic peritoneum [C481] and the histology is primary serous papillary carcinoma of peritoneum [8461/3]. Does SEER agree?

Answer:

For tumors diagnosed prior to 2007:

Code the Primary Site to C481 [Specified parts of peritoneum] and the Histology field to 8461/3 [primary serous papillary carcinoma of peritoneum].

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.
