CPT® Code 0676T

Add-On Code

Laparoscopic insertion of new or replacement of diaphragmatic lead(s), permanent implantable synchronized diaphragmatic stimulation system for augmentation of cardiac function, including connection to an existing pulse generator; each additional lead (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 0676T involves the laparoscopic insertion of new or replacement diaphragmatic lead(s) as part of a permanent implantable synchronized diaphragmatic stimulation (SDS) system. This system is specifically designed to augment cardiac function, particularly in patients suffering from moderate to severe heart failure while maintaining preserved ventricular synchrony. The primary goal of this procedure is to enhance the heart's ability to pump blood more effectively, thereby improving overall blood flow without placing additional stress on the heart muscle. The SDS system operates by stimulating the diaphragm in synchronization with the cardiac cycle, which modifies chest pressure and facilitates better filling and emptying of the heart. The device itself comprises an implantable pulse generator, bipolar active fixation leads, and programming software. During the laparoscopic procedure, two small incisions, each approximately half an inch in length, are made to allow for the implantation of the bipolar leads on the underside of the diaphragm. Additionally, a small subcutaneous pocket is created in the abdominal area to accommodate the pulse generator, which is responsible for detecting cardiac activity. The leads are then connected to this pulse generator, which delivers a small electrical shock to stimulate a specific area of the diaphragm, ensuring that normal breathing is not affected. It is important to note that this code is used for reporting the placement of the second or any additional lead, while other codes are designated for the implantation or complete replacement of the entire system or for the first lead placement. This structured approach ensures that the procedure is accurately documented and billed, reflecting the complexity and specificity of the intervention performed.
