CPT® Code 0797T

Transcatheter insertion of permanent dual-chamber leadless pacemaker, including imaging guidance (eg, fluoroscopy, venous ultrasound, right atrial angiography, right ventriculography, femoral venography) and device evaluation (eg, interrogation or programming), when performed; right ventricular pacemaker component (when part of a dual-chamber leadless pacemaker system)

The procedure described by CPT® Code 0797T involves the transcatheter insertion of a permanent dual-chamber leadless pacemaker, which is a sophisticated medical device designed to regulate heart rhythms. A leadless pacemaker is a compact pulse generator that contains an integrated battery and electrode, eliminating the need for traditional leads that connect the pacemaker to the heart. This specific procedure is indicated for patients suffering from conditions such as sinus node dysfunction, where the heart's natural pacemaker fails to function properly, and atrioventricular (AV) block, which disrupts the electrical signals between the heart's chambers. The dual-chamber system allows for more precise pacing of both the atrium and ventricle, enhancing the heart's ability to pump blood effectively. In certain clinical scenarios, the ventricular component of the dual-chamber leadless pacemaker may be inserted independently. This can occur when a dual system is being placed in stages or when an existing ventricular component has malfunctioned, making it safer to introduce a new leadless pacemaker without removing the old one. Prior to the insertion, surface EKG electrodes or programming leads may be applied to the patient's chest to facilitate monitoring and programming of the device. The procedure requires careful imaging guidance, which may include fluoroscopy, venous ultrasound, and various angiographic techniques to ensure accurate placement of the pacemaker within the heart. Overall, this advanced procedure represents a significant innovation in cardiac pacing technology, providing a less invasive option for patients requiring heart rhythm management.
