What 58580 covers
This procedure treats uterine leiomyomas by delivering radiofrequency energy through an instrument passed through the cervix. Intraoperative ultrasound guides placement and monitors treatment of the targeted fibroids. Gynecologists typically perform it as a uterine-sparing treatment in a surgical setting. Unlike myomectomy, the technique ablates fibroid tissue rather than excising it.
Report the code for the transcervical radiofrequency procedure; it covers treatment of one or more fibroids and includes the intraoperative ultrasound guidance and monitoring. Documentation should identify the radiofrequency technique and support treatment of uterine fibroids. The procedure has a 10-day global period, including related postoperative visits during that period. When it is performed with other procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this uterine procedure. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.
