Summary & Overview
CPT 50545: Radical Nephrectomy with Removal of Kidney and Surrounding Structures
CPT code 50545 denotes a radical nephrectomy that removes the kidney along with adjacent tissues such as Gerota's fascia, regional lymph nodes, the adrenal gland, and surrounding fat. This code is used to report extensive renal surgical resections, most commonly for malignant renal tumors or other conditions requiring en bloc removal of the kidney and adjacent structures. Nationally, accurate use of this code affects hospital billing, surgical case mix reporting, and quality measurement for urologic oncology care.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find an explanation of the clinical context for use of CPT code 50545, typical sites of service, and common billing considerations. The publication outlines benchmarks for utilization and payment where available, highlights relevant policy and coding guidance updates that influence claim adjudication, and summarizes clinical scenarios that commonly justify reporting this code. Additionally, the analysis provides guidance on documentation elements and operative details that support appropriate coding and medical necessity determinations. Data not available in the input will be noted as such in relevant sections.
Billing Code Overview
CPT code 50545 describes the surgical removal of a kidney (nephrectomy) including surrounding structures such as Gerota's fascia, nearby lymph nodes, the adrenal gland, and associated perinephric fatty tissue. This procedure represents an extensive radical nephrectomy intended to remove the kidney and adjacent tissues when necessary for oncologic control or other major renal pathology.
Service Type: Inpatient or ambulatory surgical procedure (major abdominal/urologic surgery)
Typical Site of Service: Operating room in a hospital setting or an ambulatory surgical center, with postoperative recovery in a PACU or inpatient ward depending on clinical status.
Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old with a renal mass suspicious for renal cell carcinoma found on imaging who is scheduled for a radical nephrectomy. The patient presents after cross-sectional imaging (CT or MRI) demonstrating a solid enhancing renal lesion with possible perinephric fat involvement or regional lymphadenopathy. Preoperative workflow includes history and physical, laboratory testing (CBC, CMP, coagulation studies), informed consent discussing removal of the kidney and surrounding structures (Gerota's fascia, perinephric fat, regional lymph nodes, possible adrenal gland), anesthetic evaluation, and medication reconciliation. Intraoperative workflow involves a general anesthetic, open or laparoscopic approach to remove the kidney en bloc with associated fatty tissue and regional nodes; possible adrenalectomy if tumor location or intraoperative findings indicate. Postoperative care includes monitoring in PACU, pain control, early ambulation, renal function monitoring, pathology submission of the nephrectomy specimen, and discharge planning with follow-up for oncology or urology as needed.
