What 59120 covers
This code describes operative treatment of an ectopic pregnancy implanted in a fallopian tube or ovary when the surgeon removes the affected tube, ovary, or both. An obstetrician-gynecologist typically performs the procedure in an operating room through an abdominal approach. A tubal pregnancy with a damaged tube requiring salpingectomy is a common clinical context; ovarian ectopic pregnancy may require oophorectomy.
Choose the code based on the implantation site, operative approach, and whether a tube or ovary is removed. The operative report should identify the ectopic site, approach, and structures excised; a tube-preserving operation is reported with a different code. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
