About 59121: Open ectopic pregnancy treatment with organ preservation
Reports open abdominal surgery for a tubal or ovarian ectopic pregnancy when the pregnancy is treated without removing the affected tube or ovary.
An obstetrician-gynecologist typically reports this for open abdominal surgery to treat a tubal or ovarian ectopic pregnancy while preserving the affected tube or ovary. The operation may involve opening the tube or ovary and removing the ectopic gestational tissue; the defining distinction is that salpingectomy and oophorectomy are not performed. The service is generally provided in an operating room when surgical treatment is needed.
The operative report should identify the ectopic site, the open approach, the treatment performed, and preservation of the tube or ovary. This code has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
