Summary & Overview
CPT 50572: Endoscopic Examination of Kidney, Renal Pelvis, and Ureter
CPT code 50572 represents an endoscopic examination of the kidney and upper urinary tract performed after creating an external opening between the renal collecting system or renal pelvis and the skin. Nationally relevant for urology and interventional nephrology services, this code captures procedures where direct visualization of the kidney, renal pelvis, and ureter is required through a surgically created tract. The code is commonly used in settings that require access to the collecting system for diagnostic inspection, removal of obstruction, or to assist therapeutic interventions.
Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context about the procedure type and typical sites of service, benchmarks and utilization patterns where available, and any notable policy or coding considerations that affect coverage and billing. The publication also outlines common modifiers and payer coverage patterns when available, and summarizes implications for facility and professional claims. Data not available in the input is noted where specific payer rates, taxonomies, or ICD-10 mappings would otherwise be expected.

This procedure is an endoscopic examination of the upper urinary tract performed through a surgically created tract to the collecting system.
-
Service type: Endoscopic examination of the kidney and upper urinary tract via a surgically created nephrostomy or pyelostomy tract

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with recurrent flank pain and imaging-confirmed hydronephrosis presents for creation of a percutaneous nephrostomy tract and diagnostic endoscopic evaluation of the collecting system. The interventional urologist obtains informed consent, places the patient prone in the angiography suite or interventional radiology suite, and uses fluoroscopic and ultrasound guidance to create an external conduit from skin to renal pelvis. After establishing the nephrostomy tract and appropriate dilation, the provider inserts an endoscope through the tract to directly visualize the kidney, renal pelvis, and proximal ureter to evaluate for obstruction, stones, strictures, or tumor. Biopsy, stone extraction, or placement of internal drainage devices may occur during the same encounter depending on findings. Typical site of service is an ambulatory surgery center or hospital operating room/interventional radiology suite. Common clinical workflow elements include pre-procedure imaging review, conscious sedation or general anesthesia administered by anesthesia team, sterile percutaneous access, tract dilation, endoscopic inspection and any adjunctive interventions, and post-procedure monitoring with nephrostomy tube management and discharge planning.
