CPT 0236T: Aortic Plaque Removal, Open or Percutaneous

CPT code 0236T designates a vascular procedure to restore blood flow in a narrowed or blocked abdominal aorta by removing deposited plaque via open or percutaneous techniques. This code is relevant nationally for vascular surgery, interventional radiology, and hospital reimbursement because it captures a complex, potentially high-resource intervention for aorto-occlusive disease.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, site-of-service considerations, and typical use cases for the code. The publication provides benchmarks where available, summarizes policy considerations that affect coverage and payment, and outlines coding context for hospital and procedural billing workflows.

This summary is intended to clarify what the code represents, how it is used across inpatient and procedural settings, and what stakeholders should know about its clinical purpose and administrative implications. Data not available in the input is noted where relevant in detailed sections.

Billing Code Overview

CPT code 0236T describes a vascular procedure to restore blood flow in a narrowed or blocked abdominal aorta by removing deposited plaque. The procedure can be performed via an open surgical approach or a percutaneous (catheter-based) technique.

Service type: Vascular aortic plaque removal (open or percutaneous aortic endarterectomy/thrombectomy)
Typical site of service: Hospital operating room or interventional suite; may also occur in an inpatient or outpatient hospital setting depending on clinical complexity and site capabilities.

Clinical & Coding Specifications

Clinical Context

A 72-year-old male with progressive exertional leg pain, diminished femoral pulses, and an ankle-brachial index of 0.6 presents after noninvasive vascular testing (ABI, duplex ultrasound, and CTA) demonstrating atherosclerotic occlusive disease with a hemodynamically significant stenosis of the infrarenal abdominal aorta. The vascular surgery team evaluates the patient in the outpatient clinic and determines that revascularization is indicated to restore distal perfusion and relieve symptoms. Preoperative workup includes cardiopulmonary risk assessment, medication optimization (antiplatelet and statin therapy), and informed consent discussing open versus percutaneous options.

In the operating suite or hybrid endovascular suite, the provider performs an aortic endarterectomy or percutaneous transluminal angioplasty with mechanical plaque debulking as indicated by anatomy and surgical judgment. The primary goal is removal of atherosclerotic plaque from the narrowed or occluded abdominal aorta to restore luminal diameter and improve downstream blood flow. Typical intraoperative workflow includes vascular access (open femoral exposure or percutaneous access), arteriography for lesion localization, plaque removal or atherectomy, adjunctive balloon angioplasty, and selective stent placement if required. Post-procedure care involves hemodynamic monitoring, limb perfusion checks, anticoagulation or antiplatelet management, and outpatient follow-up with duplex surveillance.
