About 50557: Percutaneous renal endoscopic lesion treatment
Reports percutaneous endoscopic treatment of a renal lesion by fulguration or excision through nephrotomy or nephrostomy access.
This service covers percutaneous renal endoscopy in which a urologist treats a lesion seen within the kidney through nephrotomy or nephrostomy access, using endoscopic fulguration or excision. It is typically performed in an operating room. Select it for lesion-directed treatment, distinguishing the work from diagnostic inspection, tissue sampling, stone or foreign-body removal, and the separate tumor-resection service.
Document the access route, side, lesion treated, and whether fulguration or resection was performed. When related renal endoscopies are performed together, CMS endoscopy-family pricing applies, so combined procedures are not automatically valued as independent full services. The code has a 0-day global period, which includes same-day preoperative and postoperative care. Modifier 50 is paid at 150% for bilateral procedures. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeon and team-surgery billing are not permitted.

50557 billing questions
How does this differ from renal endoscopy with biopsy?
Report this code when the endoscopic work treats a lesion by fulguration or resection. Use 50555 when the documented service is tissue sampling by biopsy.
How does this differ from renal endoscopy for stone or foreign-body removal?
This code describes lesion-directed fulguration or excision. Code 50561 describes endoscopic removal of a calculus or foreign body.
When is 50562 a closer fit?
Use 50562 for the distinct endoscopic resection of a renal tumor. Choose this code when the documented treatment is lesion fulguration or resection rather than that tumor-resection service.
Can related renal endoscopy services be reported in the same session?
Related endoscopies performed together are subject to endoscopy-family pricing. Document each service performed; CMS pricing rules account for the related procedures.
How is bilateral treatment reported?
For a bilateral procedure, report modifier 50; CMS pays this code at 150%.
What documentation supports assistant-at-surgery payment?
The record must document the medical necessity of the assistant. Co-surgeon and team-surgery billing 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
