Summary & Overview
CPT 50955: Endoscopic Ureteral Biopsy via Established Tract
CPT code 50955 represents an endoscopic biopsy of the ureteral system performed through an existing access tract to the skin and ureter. This diagnostic procedure is used to sample lesions in the ureter, renal pelvis, or kidney when tissue diagnosis is required. Nationally, accurate coding and site-of-service designation for this procedure affect clinical documentation, utilization monitoring, and payer adjudication for specialized urologic and interventional procedures.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical intent and common service settings, benchmark considerations for payer coverage and claim adjudication, and the clinical context in which the procedure is typically performed. The publication highlights typical sites of service (inpatient hospitals and outpatient surgical centers), common clinical indications for biopsy of ureteral lesions, and practical notes on documentation elements that influence billing and claims processing.

Billing Code Overview
CPT code 50955 describes an endoscopic biopsy of the ureteral system performed through an existing percutaneous or surgical tract. The procedure involves examination of the kidney, renal pelvis, and ureter with an endoscope passed through an opening already established between the skin and ureter to obtain tissue for diagnosis of ureteral lesions.
-
Service type: Endoscopic ureteral biopsy (diagnostic biopsy via pre-established tract)
-
Typical site of service: Hospital inpatient or outpatient surgical center where percutaneous or surgically created access to the ureter and renal collecting system is present
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of intermittent, painless gross hematuria and an indwelling ureteral stent presents for evaluation of a suspicious ureteral lesion identified on CT urogram. The urologist performs a ureteroscopy through a previously created percutaneous nephrostomy-to-ureter tract to visualize the renal pelvis and ureter and obtain targeted biopsies of the lesion under endoscopic guidance. The patient is brought to an ambulatory surgical center or hospital procedure suite, placed under general or regional anesthesia, and positioned for endoscopic access. The provider inspects the kidney, renal pelvis, and ureter through the existing skin-to-ureter tract, identifies the lesion, obtains tissue with biopsy forceps, and submits specimens for pathology. Hemostasis is confirmed and the nephrostomy or stent is managed per intraoperative findings. Typical documentation includes preoperative diagnosis, indication for biopsy, description of the established tract, anesthesia type, findings, number and site of biopsies, specimen labeling, complications (if any), and disposition.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Normally expected services by the defining provider | Use for a standard, uncomplicated procedure performed by the primary surgeon when reporting professional services. |
22 | Increased procedural services | Use when documentation supports substantially greater work than typical (extensive adhesiolysis, prolonged operative time) for the biopsy through an established tract.
