CPT® Code 0155T

Deleted

The procedure described by CPT® Code 0155T involves the laparoscopic implantation or replacement of gastric stimulation electrodes specifically located in the lesser curvature of the stomach. This surgical intervention is primarily indicated for the treatment of morbid obesity, particularly in patients who may also be diabetic. Gastric stimulation works by reducing food intake and delaying the process of gastric emptying, which can aid in weight management and improve metabolic control in these patients. 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 surgically implanted into a subcutaneous pocket created in the abdominal wall, typically beneath the rib cage, ensuring it is securely positioned. The two lead wires, equipped with electrodes, are then inserted into the muscle wall of the lesser curvature of the stomach using laparoscopic instruments. These leads are carefully tunneled under the skin and connected to the generator, allowing for the delivery of electrical stimuli to the stomach. The stimulation can be administered in various forms, including long pulses in continuous cycles or pulse trains that oscillate on and off for brief intervals. For cases requiring laparoscopic revision or removal of gastric stimulation electrodes, CPT® Code 0156T should be utilized.
