CPT® Code 0680T

Insertion or replacement of pulse generator only, permanent implantable synchronized diaphragmatic stimulation system for augmentation of cardiac function, with connection to existing lead(s)

The procedure described by CPT® Code 0680T involves the insertion or replacement of a pulse generator as part of a permanent implantable synchronized diaphragmatic stimulation (SDS) system. This advanced medical device is specifically designed to augment cardiac function, particularly in patients suffering from moderate to severe heart failure while maintaining preserved ventricular synchrony. The SDS system operates by stimulating the diaphragm in synchronization with the cardiac cycle, which helps modify chest pressure. This modification facilitates improved filling and emptying of the heart, ultimately enhancing blood flow without placing additional stress on the heart muscle itself. The system comprises two bipolar active fixation leads that are implanted on the underside of the diaphragm, a pulse generator, and programming software. The pulse generator is responsible for sending small electrical shocks to stimulate a targeted area of the diaphragm, ensuring that normal breathing is not affected. A subcutaneous pocket is created in the abdominal area to securely house the pulse generator, which continuously monitors cardiac activity. It is important to note that this code specifically pertains to the insertion or replacement of the pulse generator only, with the connection to existing leads already in place, thereby streamlining the procedure for patients who have previously undergone implantation of the SDS system.
