Surgeon did laparotomy with "excision of left retroperitoneal adnexal mass". "Because of the complex nature of the cyst and chance that it could be mucinous cystadenoma, we opted to proceed with an appendectomy." Pathology showed hemorrhagic copus luteal cyst and adherent fallopian tube, not mucinous cystadenoma. No histologic abnormalites of appendix. I'm not confident of dx's I've listed to link to appendectomy: V50.49-prophylactic organ removal or V71.89- suspected condition not found. Any advice?
