CPT® Code 0412T

The procedure described by CPT® Code 0412T involves the removal of a permanent cardiac contractility modulation (CCM) system, specifically focusing on the pulse generator component. The CCM system is utilized in patients suffering from moderate to severe chronic heart failure, a condition characterized by the heart's inability to pump blood effectively. This system works by generating electrical impulses during the absolute refractory period of the cardiac cycle, which enhances the contractility of the heart muscle. Importantly, these impulses are non-excitatory, meaning they do not alter the heart's rhythm but rather modulate the strength of the muscle contractions. The removal of the pulse generator requires a surgical incision to access the device, which is then disconnected from its electrodes and extracted from the body. Following the removal, the incision is typically closed with sutures to ensure proper healing. This procedure is distinct from other related procedures, such as the removal of the transvenous electrodes or the replacement of the pulse generator, which involve additional steps and considerations.
