CPT® Code 93600

The CPT® Code 93600 refers to the procedure known as Bundle of His recording. This procedure involves the physician obtaining recordings from the bundle of His, which is a critical component of the heart's electrical conduction system. The bundle of His, also known as the atrioventricular bundle, consists of specialized conducting fibers that play a vital role in transmitting electrical impulses from the atria to the ventricles, facilitating coordinated heart contractions. During the procedure, one or more access veins, typically the femoral or jugular veins, are selected for catheter insertion. The skin over these access sites is prepared, and the veins are punctured using a needle, followed by the placement of sheaths to facilitate catheter insertion. Continuous fluoroscopic guidance is employed to insert and advance guidewires from the access veins into the heart. Once the guidewires are in place, catheters are advanced over them and positioned within the heart chambers. After the guidewires are removed, recordings of the electrical activity in the bundle of His are obtained using an electrode-mounted catheter. This test is crucial for assessing the electrical activity within the bundle of His, as any interruption or blockage in this area can lead to irregular heartbeats. The physician subsequently reviews the recordings and generates a written report detailing the findings of the procedure.
