What 59320 covers
An obstetrician-gynecologist places a reinforcing suture around the cervix through the vagina during pregnancy when cervical insufficiency creates concern for pregnancy loss or preterm birth. The procedure is typically performed in an operating room or procedure setting, often with anesthesia. This code identifies the vaginal route, rather than abdominal placement.
Report 59320 for vaginal placement; documentation should identify the pregnancy, clinical indication, route, and cerclage performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. If another procedure is performed in the same session, the highest-valued procedure is paid in full and the others are reduced to 50%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
