What 58145 covers
Code 58145 represents surgical removal of one or more uterine fibroids through the vagina while preserving the uterus. A typical situation is a leiomyoma that has prolapsed through the cervix into the vaginal canal and can be reached for excision. A gynecologist generally performs the operation in a hospital or ambulatory surgery setting.
Choose this code for the vaginal operative route, rather than an abdominal or laparoscopic approach. The operative report should identify the fibroid and describe the vaginal route and excision performed. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures occur in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this single uterine procedure. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

58145 billing questions
How is 58145 distinguished from abdominal myomectomy codes?
The defining factor is the operative route: 58145 is for vaginal excision. Abdominal myomectomy codes apply when the fibroid is removed through an abdominal incision.
Should modifier 50 be reported?
No. This is a single uterine procedure, not separate right- and left-sided work.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can another procedure be reported during the same session?
A separately performed procedure may be reported when supported, but the standard multiple-procedure reduction applies when multiple procedures are performed in the same session.
What documentation supports reporting 58145?
The operative report should identify the uterine fibroid and document that it was excised through the vaginal route.
