Summary & Overview
CPT 50576: Endoscopic Renal/Pelvic Evaluation with Biopsy or Ablation
CPT code 50576 represents a percutaneous endoscopic examination of the kidney and ureter performed through a skin incision, with possible tissue biopsy, saline irrigation, contrast ureteropyelography, and destruction of abnormal renal tissue. This code captures combined diagnostic and therapeutic maneuvers performed endoscopically on the renal collecting system and adjacent ureteral segments. Nationally, the code is relevant for hospitals and ambulatory surgical centers managing complex urologic conditions that require percutaneous access and direct visualization.
Key payers in typical coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context and service setting for this procedure, common payer considerations, and the types of benchmarks and policy topics that typically accompany coverage and reimbursement reviews for percutaneous renal endoscopic procedures. The publication outlines expected service lines, typical sites of service, and how CPT code 50576 is used in clinical documentation. Where specific payer policies, fee benchmarks, or diagnosis mappings are not provided in the input, the report will note that detailed payer policy language and fee benchmarks are outside the available data and require payer-specific review.
Billing Code Overview
CPT code 50576 describes an endoscopic procedure performed through a skin incision over the kidney or renal pelvis to examine the kidney and ureter. The provider may obtain a tissue biopsy, use saline irrigation or instillation to improve visualization, perform ureteropyelography by injecting contrast for radiologic assessment, and destroy abnormal renal tissue by electrocautery or incision.
-
Service type: Endoscopic renal/ureteral diagnostic and therapeutic procedure (percutaneous nephroscopy/nephrolithotomy–style endoscopic renal evaluation and intervention)
-
Typical site of service: Hospital operating room or ambulatory surgical center with access to fluoroscopy and endoscopic equipment

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with flank pain, gross hematuria, and imaging showing a suspicious mass in the renal pelvis. After noninvasive evaluation (CT urogram and urinalysis) fails to establish a definitive diagnosis, the urologist schedules a percutaneous nephroscopy with possible renal pelvic biopsy and lesion ablation. In the operating room or interventional suite under general anesthesia, the surgeon creates a small incision over the flank, gains percutaneous access to the renal collecting system, and inserts an endoscope to visualize the renal pelvis and ureter. Saline irrigation is used to optimize visualization. Targeted biopsies are taken of suspicious tissue for histopathology. Intrarenal contrast may be instilled for ureteropyelography to delineate anatomy or confirm collecting system integrity. If small abnormal tissue is identified, the surgeon may destroy it using electrocautery (fulguration) or resect/incise tissue endoscopically. Hemostasis is achieved and a nephrostomy tube or ureteral stent may be placed per clinical need. Typical workflow includes preoperative imaging review, informed consent addressing biopsy and possible ablation, intraoperative endoscopic evaluation with biopsy and adjunctive imaging, specimen labeling and pathology submission, and postoperative monitoring for bleeding or infection.
