Question:

Primary Site/Histology (Pre-2007): What are the correct site and histology codes for "tubal serous adenocarcinoma" identified in a fallopian tube? See Description.

Discussion:

The pathology report of a laparoscopic left salpingo-oophorectomy states: 1.5 cm intraluminal mass left fallopian tube: micro: tubal serous adenocarcinoma, poorly differentiated, infiltrates the muscular wall of the fallopian tube; serosa does not appear to be penetrated. The left ovary is negative for malignancy.

Answer:

For tumors diagnosed prior to 2007:

Code histology as 8441 [serous adenocarcinoma].

The primary site for this case is fallopian tube, not the suggested site code of ovary.

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.
