CPT® Code 0411T

Insertion or replacement of permanent cardiac contractility modulation system, including contractility evaluation when performed, and programming of sensing and therapeutic parameters; ventricular electrode only

The CPT® Code 0411T refers to the procedure involving the insertion or replacement of a permanent cardiac contractility modulation (CCM) system, specifically focusing on the ventricular electrode only. This procedure is primarily indicated for patients suffering from moderate to severe chronic heart failure. The CCM system is designed to enhance cardiac muscle contractility by delivering electrical impulses during the absolute refractory period of the cardiac cycle. These impulses are non-excitatory, meaning they do not alter the heart's rhythm but instead modulate the strength of the muscle contractions, thereby improving overall cardiac function. The procedure begins with a small incision made in the right pectoral region, where a pocket is created to house the pulse generator. Access to the heart is achieved through the right subclavian, cephalic, or axillary vein using a plastic sheath. Through this sheath, electrodes, also known as pacemaker lead wires, are inserted and guided under fluoroscopy to the heart. The positioning of the sensing lead occurs in the right atrium, while two CCM transmission leads are placed in the upper and middle regions of the right ventricular septum. After connecting the leads to the pulse generator, their location and functionality are tested to ensure proper operation. If necessary, a contractility evaluation is performed, and the pulse generator is programmed to establish the appropriate sensing and therapeutic parameters. Finally, the pulse generator is securely placed in the previously created pocket, and the incision is closed with sutures. This procedure is distinct from other related codes, such as 0408T, which covers the insertion or replacement of the entire CCM system, including both the pulse generator and transvenous electrodes, and 0409T, which pertains solely to the pulse generator. Code 0410T is specific to the insertion or replacement of the atrial electrode only, while 0411T is dedicated to the ventricular electrode insertion or replacement.
