Summary & Overview
CPT 50580: Percutaneous Nephroscopy/Nephrolithotomy, Kidney and Ureter
CPT code 50580 denotes percutaneous nephroscopy/nephrolithotomy: an endoscopic, incision-based procedure to inspect the kidney and ureter, perform ureteropyelography, and remove stones or foreign bodies. This procedure is clinically important for definitive management of obstructing renal or ureteral calculi and for diagnostic evaluation when less invasive imaging is insufficient. Nationally, it influences utilization patterns in urology, hospital procedural capacity, and payer coverage determinations for surgical stone management.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the procedural scope captured by the code. The publication also outlines expected benchmarks and policy-relevant considerations: common service settings (operating room or procedure suite), clinical indications such as stone removal or foreign body extraction, and typical imaging support like fluoroscopic ureteropyelography.
This summary equips clinicians, billing teams, and policy analysts with a clear understanding of what CPT code 50580 represents, why it matters within surgical urology, and which major national payers are relevant for coverage and billing discussions. Data not available in the input: detailed payer-specific reimbursement rates, associated taxonomies, and linked ICD-10 diagnosis codes.
Billing Code Overview
CPT code 50580 describes a percutaneous nephroscopy or nephrolithotomy procedure in which an endoscope is inserted through an incision in the skin over the kidney or renal pelvis to directly visualize the kidney and ureter. The procedure may include irrigation or instillation of saline for improved visualization, radiologic ureteropyelography with contrast injection, and removal of foreign bodies or renal/ureteral stones.
-
Service type: Percutaneous endoscopic evaluation and intervention of the kidney and ureter
-
Typical site of service: Operating room or procedure suite with access to fluoroscopy and endoscopic equipment (inpatient or outpatient surgical settings)
Clinical & Coding Specifications
Clinical Context
A 56-year-old patient presents with recurrent flank pain, hematuria, and imaging evidence of a 1.2 cm obstructing renal pelvic calculus in the proximal right collecting system. Conservative measures and extracorporeal shock wave lithotripsy were unsuccessful. The urology team schedules a percutaneous nephroscopy under general anesthesia. The provider makes a small incision through the skin and subcutaneous tissue overlying the kidney, dilates a tract into the renal pelvis, and inserts a nephroscope to visually inspect the renal collecting system and ureter. Saline irrigation is used to distend the pelvicalyceal system for improved visualization. Contrast may be injected to perform a ureteropyelogram to delineate anatomy and stone position. Using endoscopic graspers or baskets, the provider fragments and removes the stone and retrieves fragments; he also inspects for retained foreign bodies or residual calculi. Typical intraoperative workflow includes preoperative cystoscopy and placement of a ureteral catheter if needed, fluoroscopic imaging for tract creation and localization, nephrostomy tube placement or ureteral stent at procedure end, and postoperative monitoring in a surgical recovery area. Typical site of service is an operating room or ambulatory surgery center with fluoroscopy capability. The service type is a surgical endoscopic procedure of the kidney/renal pelvis (percutaneous nephroscopy) indicated for stone removal, foreign body retrieval, or diagnostic evaluation of the collecting system.
