CPT® Code 0416T

The procedure described by CPT® Code 0416T involves the relocation of a skin pocket for an implanted cardiac contractility modulation (CCM) pulse generator. This procedure is performed when there is a need to reposition a previously implanted permanent CCM system, which includes a transvenous electrode that can be either an atrial or ventricular lead. The CCM system is designed to enhance cardiac muscle contractility by delivering electrical impulses during the absolute refractory period of the cardiac cycle. These impulses are non-excitatory, meaning they do not alter the heart's rhythm but instead modulate the strength of muscle contractions. The process begins with making an incision in the skin to access the pulse generator of the CCM system. The transvenous lead electrode is then disconnected from the pulse generator and repositioned under fluoroscopic guidance to ensure optimal placement. After the lead is correctly positioned, it is reconnected to the pulse generator, and the incision is sutured closed. In cases where the pulse generator itself needs to be relocated, a new skin pocket is created by making an incision near the existing pulse generator site. The pulse generator, along with the electrodes, is then carefully tunneled to the new pocket location, and the incision is subsequently closed with sutures. This procedure is essential for maintaining the functionality of the CCM system and ensuring effective treatment for patients with specific cardiac conditions.
