What 50957 covers

A urologist uses a ureteroscope to treat a lesion within the ureter, with the therapeutic work performed endoscopically rather than through an open incision. Fulguration is a typical example of treatment directed at a ureteral lesion. The procedure is generally performed in an operating-room or other procedural facility; the record should identify the lesion and describe the treatment actually carried out.

Select this code when the operative report supports endoscopic treatment, not merely inspection or tissue sampling. Document the treated site, findings, and technique. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies rather than pricing each as an unrelated procedure. For bilateral reporting, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are 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.

50957 billing questions

When is 50957 preferable to the biopsy code 50955?

Use 50957 when the documented work treats a ureteral lesion endoscopically. Use 50955 when the service is ureteroscopic biopsy rather than lesion treatment.

Can diagnostic ureteroscopy be reported separately with 50957?

The diagnostic inspection that leads to treatment during the same operative session is part of the therapeutic endoscopy. Related endoscopies performed together are subject to CMS endoscopy-family pricing.

How should bilateral treatment be reported?

Report modifier 50 when the procedure is performed bilaterally; CMS pays the bilateral procedure at 150%.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.

What documentation supports 50957?

The operative report should identify the ureteral lesion and describe the endoscopic treatment performed, such as fulguration. A report describing inspection or biopsy alone does not support this treatment code.

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.
