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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

57155 billing questions

When should 57155 be chosen over 57156?

Use 57155 for placement of a uterine tandem and/or vaginal ovoids. Code 57156 describes placement of a vaginal brachytherapy device without that tandem-and-ovoid arrangement.

Does 57155 include radiation treatment delivery?

No. It reports applicator placement; report the appropriate brachytherapy delivery service separately when radiation is delivered and the requirements for that service are met.

Can modifier 50 be appended when applicators are placed on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.

How does the 0-day global period affect same-day care?

Same-day preoperative and postoperative care is included in 57155. The code has no postoperative global days beyond the date of service.

Can an assistant surgeon report services with 57155?

CMS applies a statutory restriction to assistant-at-surgery payment for this code. Co-surgeons are permitted, but team surgery is not.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
