CPT® Code 0571T

Insertion or replacement of implantable cardioverter-defibrillator system with substernal electrode(s), including all imaging guidance and electrophysiological evaluation (includes defibrillation threshold evaluation, induction of arrhythmia, evaluation of sensing for arrhythmia termination, and programming or reprogramming of sensing or therapeutic parameters), when performed

The procedure described by CPT® Code 0571T involves the insertion or replacement of a subcutaneous implantable cardioverter-defibrillator (SICD) system that utilizes substernal electrode(s). This type of device is specifically designed to treat ventricular arrhythmias in patients who require an implantable cardioverter-defibrillator (ICD) but have limited access to their venous system. Unlike traditional ICDs, the SICD system does not enter the vascular system or make contact with the beating heart, making it a suitable option for patients with certain anatomical or medical considerations. The procedure includes comprehensive imaging guidance and an electrophysiological evaluation, which encompasses several critical assessments such as defibrillation threshold evaluation, induction of arrhythmia, evaluation of sensing for arrhythmia termination, and the programming or reprogramming of sensing or therapeutic parameters. This thorough evaluation ensures that the device is optimally configured to respond to the patient's specific cardiac needs, enhancing the effectiveness of the SICD system in preventing life-threatening arrhythmias.
