Summary & Overview
CPT 0234T: Renal Artery Revascularization with Plaque Removal
CPT code 0234T represents renal artery revascularization with plaque removal performed by open surgical or percutaneous techniques to restore renal blood flow. This procedure addresses hemodynamically significant renal artery stenosis that can contribute to hypertension and renal dysfunction. Nationally, the code is relevant for hospitals and interventional practices managing vascular disease and impacts facility and physician billing for complex endovascular or surgical renal interventions.
Key payers in a national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for renal artery plaque removal, typical sites of service, and which payers commonly cover such procedures. The publication also outlines expected benchmarks and utilization patterns, summarizes recent policy updates affecting coverage and coding practice, and highlights coding nuances that affect claim submission and reimbursement across payers.
This summary is intended to orient clinical administrators, billing professionals, and policy analysts to the purpose and billing context of CPT code 0234T, providing a foundation for deeper review of payer-specific policies, reimbursement benchmarks, and clinical documentation requirements.
Billing Code Overview
CPT code 0234T describes a procedure to restore blood flow in a narrowed or blocked renal artery by removing deposited plaque. The service can be performed via an open surgical approach or percutaneously and involves re-establishing adequate renal arterial perfusion.
-
Service type: Vascular interventional or surgical revascularization of the renal artery
-
Typical site of service: Hospital operating room, hybrid operating suite, or interventional radiology/cardiac catheterization laboratory
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old with long-standing hypertension and worsening renal function who presents with refractory hypertension and unexplained decline in estimated glomerular filtration rate (eGFR). Imaging (renal duplex ultrasound, CT angiography, or MR angiography) demonstrates a hemodynamically significant ostial narrowing of the renal artery consistent with atherosclerotic renal artery stenosis. After multidisciplinary review, the vascular surgeon or interventional radiologist schedules revascularization via percutaneous transluminal renal angioplasty with atherectomy or stent placement to restore renal perfusion and control blood pressure.
The clinical workflow includes pre-procedure evaluation (medical optimization, medication reconciliation, contrast allergy assessment, informed consent), intraprocedural vascular access (commonly femoral or radial), angiography to confirm lesion characteristics, plaque removal or debulking via atherectomy or mechanical thrombectomy as indicated, adjunctive balloon angioplasty and possible stent deployment, completion angiography to document flow restoration, hemostasis and postoperative monitoring for contrast nephropathy, access-site complications, and blood pressure/renal function follow-up. Typical care teams include vascular surgery, interventional radiology, anesthesiology (conscious sedation or general anesthesia if required), nursing, and radiology technologists. Typical site of service is an ambulatory surgery center or hospital outpatient department with endovascular capability; inpatient admission occurs when complications or comorbidities require overnight observation or staged care.
