CPT® Code 93619

Comprehensive electrophysiologic evaluation with right atrial pacing and recording, right ventricular pacing and recording, His bundle recording, including insertion and repositioning of multiple electrode catheters, without induction or attempted induction of arrhythmia

A comprehensive electrophysiologic evaluation, designated by CPT® Code 93619, involves a detailed assessment of the electrical activity of the heart, specifically focusing on the right atrium and right ventricle. This procedure is performed without the induction or attempted induction of arrhythmia, meaning that the physician does not intentionally provoke an abnormal heart rhythm during the evaluation. The study encompasses several critical components, including right atrial pacing and recording, right ventricular pacing and recording, and His bundle recording. To facilitate this evaluation, multiple electrode catheters are inserted and repositioned within the heart. The insertion typically occurs through a puncture or small incision made over a blood vessel, often in the groin area. Once the catheters are in place, they are advanced into the right atrium and right ventricle, where they can measure and record the heart's electrical activity. The recording electrodes capture the electrical signals generated by the heart, while the stimulating electrodes are used to pace the heart, allowing for a comprehensive analysis of its function. Additionally, the His bundle recording is crucial as it monitors the electrical impulses traveling through the bundle of His, a collection of heart fibers responsible for conducting impulses from the atrioventricular (AV) node to the ventricles. This evaluation is essential for diagnosing potential conduction abnormalities that may lead to irregular heart rhythms. After the procedure, the catheters are carefully withdrawn, and pressure is applied to the puncture or incision sites to ensure proper healing and minimize bleeding.
