Summary & Overview
CPT 50574: Percutaneous Endoscopic Renal Evaluation with Biopsy
CPT code 50574 denotes a percutaneous endoscopic renal and ureteral evaluation with biopsy, a procedure used to visualize the renal pelvis and ureter and to obtain renal tissue for diagnostic purposes. Nationally, this code is relevant for managing complex urologic diagnoses where direct visualization and histologic sampling of renal tissue influence treatment planning and staging. The code applies to procedures commonly performed in ambulatory surgery centers and hospital operating rooms by urology teams.
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, common settings of care, and typical procedure elements tied to CPT code 50574. The publication also summarizes common modifiers and coding considerations, payer coverage patterns, and benchmarking elements relevant to facility and professional billing. Policy and reimbursement trends that affect utilization and documentation expectations are highlighted, along with operational notes on service lines and typical billing scenarios.
This executive summary prepares clinicians, billing professionals, and policy analysts to understand the code’s clinical role, where it is typically performed, and the payer landscape that influences coverage and reimbursement at a national level.
Billing Code Overview
CPT code 50574 describes a percutaneous endoscopic examination of the kidney and ureter with biopsy. In this procedure an endoscope is inserted through a small incision in the skin over the kidney or renal pelvis to visualize the renal collecting system and ureter and to obtain a tissue sample from the kidney for pathologic analysis. The procedure may include irrigation or instillation of saline to improve visualization and may include ureteropyelography or radiologic study of the ureter and renal pelvis with contrast injection.

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with persistent hematuria, flank pain, and a suspicious renal mass identified on CT scan. After urology consultation, percutaneous kidney endoscopy with biopsy is scheduled. The patient is brought to an ambulatory surgery center (ASC) or hospital operating room (OR). Under conscious sedation or general anesthesia, the interventional urologist or endourologist makes a small flank incision and inserts a rigid or flexible endoscope through the skin into the renal pelvis. Irrigation with saline is used for visualization. Targeted tissue is obtained via biopsy forceps for histopathology. Contrast may be instilled to perform ureteropyelography to delineate collecting system anatomy and to evaluate for ureteral involvement. Specimens are submitted to pathology; intraoperative fluoroscopy or radiographs may be used. Typical postprocedure workflow includes recovery in PACU, vital sign monitoring, pain control, urine output observation, discharge instructions if in ASC or admission for observation if complications or comorbidities exist.
