Answer: You should consider this a partial orchiectomy (54522, Orchiectomy, partial, for the open procedure, or 54690, Laparoscopy, surgical; orchiectomy, if performed laparoscopically).
Keep in mind: You will more than likely hit the gender/procedure barrier if you use this code. Your best bet is to go with an unlisted-procedure code (58999, Unlisted procedure, female genital system [nonobstetrical], if the ob-gyn performs the procedure through an abdominal incision, or 49329, Unlisted laparoscopy procedure, abdomen, peritoneum and omentum, if performed with a laparoscope) and then send in the explanation. This will probably get you paid faster.
