CPT® Code 0675T

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; first lead

The CPT® Code 0675T refers to the laparoscopic insertion of a new or replacement diaphragmatic lead as part of a permanent implantable synchronized diaphragmatic stimulation (SDS) system. This advanced medical procedure 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. The system comprises an implantable pulse generator, bipolar active fixation leads, and programming software, all of which work together to support cardiac function. During the procedure, a minimally invasive laparoscopic technique is employed, involving the creation of two small half-inch incisions through which the bipolar leads are implanted on the underside of the diaphragm. Additionally, a small subcutaneous pocket is formed in the abdomen to accommodate the pulse generator, which is responsible for detecting cardiac activity. The leads are then connected to the 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 applicable when only the first new diaphragmatic lead is placed or when an existing lead is replaced and connected to an already positioned pulse generator. For the implantation or complete replacement of the entire system, CPT® Code 0674T should be reported, while CPT® Code 0676T is designated for the placement or replacement of the second or any additional leads.
