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.
