Summary & Overview
CPT 50230: Nephrectomy, Kidney Removal
CPT code 50230 represents nephrectomy, the surgical removal of a kidney or part of a kidney. This code is used for reporting major urologic surgery and is relevant nationally due to the clinical complexity, perioperative resource use, and implications for hospital and outpatient surgical reimbursement. Nephrectomy is performed for indications including renal tumors, severe renal trauma, and selected nonmalignant diseases.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for CPT code 50230, typical sites of service, and the service type. The publication summarizes payer coverage considerations, common modifiers used with surgical codes, and typical clinical pathways associated with nephrectomy. It also highlights benchmarking topics such as utilization patterns, site-of-service variation, and coding considerations that affect claim adjudication and billing trajectories.
This summary is written for a national audience and provides clinicians, coding professionals, and policy analysts with the clinical and billing context needed to interpret CPT code 50230 in operational and policy discussions.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old male with a history of smoking and incidental imaging finding of a 4.5 cm enhancing mass in the right renal cortex consistent with a renal cell carcinoma. He presents to a urology clinic for evaluation. Preoperative workup includes renal function testing (serum creatinine, eGFR), chest imaging for metastasis staging, and cross-sectional abdominal CT or MRI. The patient is evaluated by a urologist and a preoperative anesthesia team, and informed consent is obtained for nephrectomy. Depending on tumor size and location, a surgeon may plan a partial nephrectomy (nephron-sparing) or a radical nephrectomy (complete kidney removal). The procedure is typically performed in an inpatient operating room or ambulatory surgical center with general endotracheal anesthesia. Intraoperative considerations include potential vascular control, tumor excision with negative margins, and possible reconstruction of the renal parenchyma. Postoperative workflow includes PACU monitoring, pain control, fluid management, serial renal function tests, DVT prophylaxis, pathology review, and discharge planning with outpatient follow-up and oncologic surveillance.
