What 58546 covers

A gynecologic surgeon removes uterine fibroids through a laparoscopic approach while preserving the uterus, typically in an operating room. This complex level is selected when the operation involves five or more intramural myomas or the removed myomas meet the 250-gram weight threshold. The surgeon may make incisions in the uterus to remove the fibroids and repair the uterine wall; the operative report should describe the approach and work performed.

Select the level using the documented number of intramural myomas and the total weight of the excised tissue. Record both when available, along with the sites treated, so the basis for this level is clear. CMS assigns a 90-day global period, including 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% reduction. Assistant-at-surgery and co-surgeon payment may be allowed; team-surgery payment is not permitted. Modifier 50 is not appropriate for this uterine procedure.
