CPT® Code 0413T

The procedure described by CPT® Code 0413T involves the removal of a permanent cardiac contractility modulation (CCM) system, specifically focusing on the transvenous electrode, which can be either atrial or ventricular. The CCM system is utilized in patients suffering from moderate to severe chronic heart failure, a condition where the heart is unable 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 instead modulate the strength of the muscle contractions. The removal process requires a surgical incision to access the pulse generator, which is the device that produces these electrical impulses. Once the pulse generator is exposed, the electrode is disconnected and removed, followed by the closure of the incision with sutures. This procedure is critical for patients who may need to replace or discontinue the use of the CCM system due to various clinical reasons.
