What 50955 covers

A urologist passes an endoscope into the ureter to inspect its lining and obtain tissue from a finding that needs pathologic evaluation. A typical clinical situation is sampling a suspicious upper-tract urothelial lesion. The service is commonly performed in a hospital or ambulatory surgery setting; Medicare recorded facility services for this code in 2024.

Report the code when the documented ureteroscopic service includes biopsy, and support it with the indication, ureter and side examined, endoscopic findings, and tissue-sampling details. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, endoscopy family pricing applies. For bilateral procedures, modifier 50 is paid at 150%. An assistant at surgery is paid only when medical necessity is documented; 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.

50955 billing questions

When should this code be selected instead of diagnostic ureteroscopy?

Use this code when the ureteroscopic service includes biopsy. A diagnostic-only examination without tissue sampling is represented by a diagnostic ureteroscopy code, such as 50951.

Can the biopsy be reported separately from the ureteroscopy?

This code describes ureteroscopy with biopsy. The record should show the endoscopic examination and tissue sampling; do not treat the biopsy as an unrelated service merely because a specimen is sent to pathology.

How does CMS handle related endoscopies performed together?

Endoscopy family pricing applies when related endoscopies are performed together. The code’s payment is subject to that family pricing in the combined service.

How is a bilateral procedure reported?

For a bilateral procedure, report modifier 50; CMS pays the procedure at 150%. Document the ureteral work on both sides.

What assistant or co-surgeon rules apply?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this 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.
