CPT® Code 0156T

Deleted

The procedure described by CPT® Code 0156T involves the laparoscopic revision or removal of gastric stimulation electrodes specifically located at the lesser curvature of the stomach. Gastric stimulation electrodes are devices that are surgically implanted to assist in the management of morbid obesity, particularly in patients who may also have diabetes. The primary function of these electrodes is to reduce food intake and delay gastric emptying, which can contribute to weight loss and improved metabolic control. The procedure utilizes a pacing lead system, commonly referred to as a gastric pacemaker, which consists of a generator device and two stimulation leads. The generator is implanted in a subcutaneous pocket created in the abdominal wall, typically beneath the rib cage, while the stimulation leads are inserted into the muscle wall of the stomach. This is achieved through laparoscopic techniques, which involve the use of specialized instruments to minimize invasiveness. The leads are then tunneled under the skin and connected to the generator, allowing for the delivery of electrical stimuli to the stomach. These stimuli can be administered in various patterns, such as long pulses in continuous cycles or pulse trains that oscillate on and off, to effectively manage gastric function. The use of CPT® Code 0156T is specifically designated for cases where there is a need to revise or remove these gastric stimulation electrodes.
