CPT® Code 63655

The procedure described by CPT® Code 63655 involves a laminectomy for the implantation of neurostimulator electrodes, specifically a plate or paddle, into the epidural space. This surgical intervention is primarily aimed at treating chronic back and/or leg pain through the use of spinal cord stimulation. The underlying principle of this procedure is to alleviate pain by delivering electrical stimulation to the spinal cord, which activates pain-inhibiting neurons and produces a tingling sensation that effectively masks pain sensations. The process begins with the creation of an incision over the spine, followed by the dissection of soft tissue to expose the lamina, which is a bony structure of the vertebra. A portion or the entirety of the lamina is then excised to gain access to the epidural space. Once this access is achieved, the electrode plate or paddle is carefully positioned within the epidural space and secured to the spine. After placement, the patient is awakened to test the device, ensuring proper functionality and that the stimulation effectively alleviates pain. This procedure is a critical step in the overall management of chronic pain, providing patients with a potential long-term solution to their discomfort.
