The CPT® Code 93620 refers to a comprehensive electrophysiologic evaluation, which is a detailed study of the electrical activity of the heart, specifically focusing on the right atrium and right ventricle. This procedure involves the insertion and repositioning of multiple electrode catheters, which are specialized tools used to measure and stimulate the heart's electrical signals. The primary goal of this evaluation is to induce or attempt to induce arrhythmia, which is an irregular heartbeat, allowing for a thorough assessment of the heart's electrical conduction system. During the procedure, the physician performs right atrial pacing and recording, right ventricular pacing and recording, and His bundle recording. To initiate the procedure, the skin is punctured or a small incision is made over one or more blood vessels, typically in the groin area. Through this access point, one or more catheters are inserted into the blood vessel(s). These catheters are equipped with recording and stimulating electrodes that are carefully threaded into the right atrium and right ventricle of the heart. Once positioned, the recording electrodes measure and document the electrical activity occurring in the right side of the heart, while the stimulating electrodes are used to pace the heart, simulating various heart rhythms. Additionally, the His bundle, a critical structure that transmits electrical impulses through the heart, is also monitored during this evaluation. The His bundle is located at the junction of the atrioventricular (AV) node and the ventricles, and any disruption in its function can lead to arrhythmias. Following the comprehensive electrophysiologic study, the physician may induce arrhythmia through pacing at different rates or by using programmed stimulation, which involves delivering timed electrical impulses to the heart. Throughout the procedure, the catheters may be repositioned to optimize the induction of arrhythmia and to gather more precise data from various sites within the heart. Upon completion of the study, the catheters are withdrawn, and pressure is applied to the puncture or incision sites to prevent bleeding. The physician then interprets the collected data and generates a written report detailing the findings of the procedure.

The comprehensive electrophysiologic evaluation represented by CPT® Code 93620 is indicated for various clinical scenarios where detailed assessment of the heart's electrical activity is necessary. The following conditions may warrant this procedure:
The procedure associated with CPT® Code 93620 involves several critical steps to ensure a thorough electrophysiologic evaluation of the heart. The following outlines the procedural steps:
After the comprehensive electrophysiologic evaluation is completed, the patient is monitored for any immediate complications, such as bleeding or arrhythmias. The access site is observed for signs of hematoma or infection. Patients are typically advised to rest and may be instructed to avoid strenuous activities for a specified period. Follow-up appointments may be scheduled to discuss the results of the procedure and any necessary treatment plans based on the findings. The physician will provide detailed instructions regarding post-procedure care and any signs or symptoms that should prompt immediate medical attention.
