Official Description

Insertion of epicardial electrode(s); endoscopic approach (eg, thoracoscopy, pericardioscopy)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33203 involves the insertion of epicardial electrode(s) through an endoscopic approach, specifically utilizing techniques such as thoracoscopy or pericardioscopy. Epicardial electrodes, also referred to as leads, are critical components used in cardiac pacing and defibrillation. These electrodes are strategically placed on the outer surface of the heart muscle to facilitate electrical stimulation, which is essential for managing various cardiac conditions. Unlike traditional methods that require an open chest incision, the endoscopic approach minimizes trauma to the chest wall and surrounding tissues, leading to potentially quicker recovery times and reduced postoperative complications. The procedure is performed with the chest cavity opened to expose the heart, allowing for precise placement of the electrodes in designated areas of the heart muscle. The choice of electrode placement depends on the type of device being utilized, whether it is a single or dual chamber permanent pacemaker or a pacing cardioverter defibrillator. This code specifically pertains to the insertion of the epicardial leads only, excluding the generator component of the device, which is typically implanted separately. The endoscopic technique represents a significant advancement in cardiac procedures, offering a less invasive option for patients requiring epicardial pacing solutions.
