Summary & Overview
CPT 33572: Coronary Artery Plaque Removal During CABG
CPT code 33572 denotes surgical removal of plaque from a coronary artery performed during a coronary artery bypass graft (CABG) procedure. The service involves accessing the coronary artery, incising the diseased segment, and extracting obstructive plaque to restore arterial patency and reduce the risk of infarction and ventricular damage. This procedure is a specialized component of cardiac surgery and is clinically significant for patients with focal intraluminal plaque complicating CABG.
Key payers commonly analyzed for this code include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides national context for clinical use and payer coverage patterns, noting which payers are included in comparative tables.
Readers will learn the clinical scope of CPT code 33572, the typical settings where the procedure is performed, and what to expect in terms of payer inclusion in analyses. The report outlines benchmarks and policy-relevant considerations tied to surgical cardiac services, summarizes any recent policy updates affecting cardiac procedural coding where available, and situates the code within the broader clinical pathway of CABG. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 33572 describes a surgical procedure in which the provider gains access to a coronary artery during a coronary artery bypass graft operation, incises the affected artery, and removes plaque as necessary. The procedure addresses obstructive atherosclerotic plaque that reduces blood flow or can embolize and cause myocardial infarction and ventricular damage.
-
Service type: Open cardiac surgical plaque removal performed as part of a coronary artery bypass graft procedure
-
Typical site of service: Inpatient hospital operating room or cardiac surgery suite
Clinical & Coding Specifications
Clinical Context
A 67-year-old male with progressive exertional angina and a prior myocardial infarction presents for surgical coronary revascularization. Coronary angiography demonstrates severe atherosclerotic narrowing of the left anterior descending artery with prominent eccentric plaque and areas of calcification. The cardiac surgery team elects to perform coronary artery bypass grafting (CABG) with concomitant coronary endarterectomy of the stenotic segment to restore distal flow.
The clinical workflow: preoperative evaluation includes history, cardiac catheterization, echocardiography, labs, and anesthesia assessment. In the operating room under general anesthesia and cardiopulmonary bypass, the surgeon exposes the target coronary artery, makes a longitudinal arteriotomy, and performs 33572 (coronary endarterectomy) by removing atheromatous plaque and smoothing the lumen. The artery is reconstructed and an appropriate bypass graft (typically using left internal mammary artery or saphenous vein) is anastomosed distal to the endarterectomy site. Postoperative care includes ICU monitoring, antiplatelet and anticoagulation management, hemodynamic support, and cardiac rehabilitation planning.
