What 57155 covers

CPT 57155 covers placement of a uterine tandem through the cervix into the uterine cavity and vaginal ovoid applicators around the cervix, when that applicator arrangement is used for intracavitary brachytherapy. A radiation oncologist or another qualified physician typically performs the placement, often in an operating room or procedure setting with anesthesia. The applicators position the radioactive source for treatment of gynecologic malignancies, including cervical cancer.

Report the placement when the documented procedure uses a uterine tandem and/or vaginal ovoids; the record should identify the applicator arrangement and its placement for brachytherapy. The code represents applicator placement, not radiation dose delivery. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted; co-surgeons are permitted, while team surgery is not permitted.
