CPT® Code 0682T

Removal of pulse generator only, permanent implantable synchronized diaphragmatic stimulation system for augmentation of cardiac function

The procedure described by CPT® Code 0682T involves the removal of a pulse generator that is part of a permanent implantable synchronized diaphragmatic stimulation (SDS) system. This system is designed to augment cardiac function, particularly in patients suffering from moderate to severe heart failure while maintaining preserved ventricular synchrony. The SDS system works by stimulating the diaphragm in synchronization with the cardiac cycle, which helps modify chest pressure. This modification facilitates better filling and emptying of the heart, ultimately improving blood flow without placing additional stress on the heart muscle. The device itself 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 impulses to stimulate a specific area of the diaphragm, which does not interfere with normal breathing. The procedure for removing the pulse generator is indicated when there is a need to discontinue the use of the device without replacing it. This may occur due to various reasons, including complications or the decision to cease therapy. It is important to note that this code specifically pertains to the removal of the pulse generator only, without any replacement or relocation of the device.
