CPT® Code 93653

Comprehensive electrophysiologic evaluation with insertion and repositioning of multiple electrode catheters, induction or attempted induction of an arrhythmia with right atrial pacing and recording and catheter ablation of arrhythmogenic focus, including intracardiac electrophysiologic 3-dimensional mapping, right ventricular pacing and recording, left atrial pacing and recording from coronary sinus or left atrium, and His bundle recording, when performed; with treatment of supraventricular tachycardia by ablation of fast or slow atrioventricular pathway, accessory atrioventricular connection, cavo-tricuspid isthmus or other single atrial focus or source of atrial re-entry

A comprehensive electrophysiologic evaluation, designated by CPT® Code 93653, involves a detailed assessment of the heart's electrical activity through the use of multiple electrode catheters. This procedure is essential for diagnosing and treating various types of arrhythmias, particularly supraventricular tachycardia. The process begins with the insertion and repositioning of these catheters, which are equipped with recording and stimulating electrodes. These electrodes are strategically placed in the right atrium, right ventricle, and left atrium or coronary sinus to monitor and induce arrhythmias. The evaluation includes right atrial pacing and recording, as well as intracardiac electrophysiologic three-dimensional mapping, which allows for a comprehensive understanding of the heart's electrical pathways. During the procedure, the skin is punctured or a small incision is made, typically in the groin area, to access the blood vessels. The catheters are then threaded through these vessels into the heart. The electrophysiologic study aims to induce arrhythmias through pacing at various rates or programmed stimulation, which helps identify the specific arrhythmogenic focus. Once located, catheter ablation is performed to eliminate the source of the arrhythmia, utilizing techniques such as radiofrequency energy, microwave energy, or cryoablation. This thorough evaluation and treatment process is crucial for managing arrhythmias effectively and ensuring patient safety.
