Summary & Overview
CPT 50548: Laparoscopic Nephroureterectomy, Kidney and Ureter Removal
CPT code 50548 identifies a laparoscopic nephroureterectomy — the surgical removal of a kidney together with its entire ureter via minimally invasive laparoscopic technique. This procedure is commonly used for definitive management of upper urinary tract malignancies or other conditions necessitating en bloc removal of the kidney and ureter. Nationally, accurate coding of complex urologic oncology procedures affects episode costs, facility utilization, and quality reporting for surgical care.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage policies and billing rules for major payers influence site-of-service decisions, preauthorization requirements, and allowable reimbursement for laparoscopic versus open approaches.
Readers will find a concise overview of clinical context for CPT code 50548, common billing considerations, and nationally relevant benchmarks where available. The publication outlines payer coverage patterns, expected sites of service, and the procedural scope captured by the code. Data not available in the input will be noted where applicable. The material is intended for coding professionals, revenue cycle staff, and clinical leaders seeking a clear, national-level reference on this specific urologic procedure code.
Billing Code Overview
CPT code 50548 describes a laparoscopic nephroureterectomy, a surgical procedure in which the provider removes an entire kidney and its ureter using minimally invasive laparoscopic techniques. The procedure represents a definitive operative treatment for conditions requiring removal of the kidney and ureter as a single specimen.

Clinical & Coding Specifications
Clinical Context
A 62-year-old female with a history of recurrent symptomatic upper urinary tract infections, long-standing nonfunctioning right kidney on nuclear renal scan, and chronic flank pain is scheduled for a laparoscopic nephroureterectomy. Preoperative evaluation includes CT urogram demonstrating a shrunken, fibrotic right kidney and distal ureteral thickening without obvious intravesical tumor. The patient is admitted to an ambulatory surgery center or inpatient hospital surgical suite based on comorbidities and anesthesia needs. Under general endotracheal anesthesia, the urology surgeon establishes a pneumoperitoneum, places laparoscopic ports, mobilizes the colon, ligates renal hilum vessels, and liberates the kidney with complete removal of the ipsilateral ureter down to the bladder cuff. The specimen is retrieved via an extraction bag; a bladder cuff may be managed laparoscopically or through a small incision. Typical intraoperative documentation includes indication, laterality, procedure performed as 50548, estimated blood loss, intraoperative findings, any complications, and disposition. Postoperative care involves pain control, monitoring for urine leak or bleeding, incentive spirometry, and follow-up imaging or pathology review as indicated.
