CPT® Code 33216

The procedure described by CPT® Code 33216 involves the insertion of a single transvenous electrode for a permanent pacemaker or implantable defibrillator. This procedure is essential for patients who require cardiac pacing or defibrillation due to various heart conditions. Initially, the existing electrode wire(s) of the device are assessed for functionality; if any are found to be defective, they are removed. A new electrode wire is then inserted and carefully positioned within the heart, specifically in either the right atrium or the right ventricle, depending on the patient's needs. This new wire is subsequently reattached to the existing pulse generator, which is the device that delivers electrical impulses to the heart. The procedure necessitates a surgical incision in the upper chest to access a vein, such as the cephalic, subclavian, or jugular vein, through which the electrode wire is advanced into the heart under radiological guidance. This meticulous process ensures that the electrode is correctly placed against the heart wall, allowing for effective pacing or defibrillation. It is important to note that this code specifically pertains to single chamber devices, while a different code, CPT® 33217, is designated for dual chamber devices that utilize two electrode wires.
