What 57531 covers
This operation removes the cervix along with surrounding parametrial tissue and a portion of the upper vagina through a vaginal approach. Gynecologic oncologists typically perform it in an operating room for selected patients with early cervical cancer when preserving the uterine body is part of the treatment plan. The operative report should establish the radical extent of the resection and the vaginal approach, rather than a simple cervical amputation or a limited excision for diagnosis or dysplasia.
Report the service when the documented procedure matches that radical vaginal operation. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the following 90 days. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. CMS pricing treats this code as bilateral, so modifier 50 does not increase payment. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
