Question:

CS Extension/CS Mets at Dx--Peritoneum: How are these fields coded for extraovarian peritoneal carcinomas presenting with multiple peritoneal implants? See Discussion.

Discussion:

Patient presented with large omental cake and multiple peritoneal implants including implants on the rectosigmoid serosa and right ovary. Path revealed papillary serous adenocarcinoma consistent with peritoneal primary.

Per AJCC Manual, extraovarian peritoneal carcinoma is usually staged with the ovarian staging classification.

We understand that the CS Manual will eventually be revised to include staging for extraovarian peritoneal primaries. In the meantime, how do we use the existing CS scheme for peritoneum to code these cases?

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Code CS Extension 99 [unknown] and CS Mets at DX 99 [unknown].
