CPT® Code 63664

Revision including replacement, when performed, of spinal neurostimulator electrode plate/paddle(s) placed via laminotomy or laminectomy, including fluoroscopy, when performed

The procedure described by CPT® Code 63664 involves the revision and potential replacement of a spinal neurostimulator electrode plate or paddle that has been previously implanted via a laminotomy or laminectomy. This procedure is specifically designed for patients experiencing chronic back and/or leg pain, where an implantable spinal cord stimulation system is utilized to alleviate discomfort. The mechanism of action involves the electrical stimulation of the spinal cord, which activates pain-inhibiting neurons and induces a tingling sensation that effectively masks pain sensations. The revision process may include repositioning the existing electrode plate or paddle to optimize pain control or replacing it entirely if necessary. The procedure is performed under fluoroscopic guidance, which allows for precise visualization of the spinal structures during the operation. An incision of 2 to 5 inches is made over the spine to access the electrode plate or paddle, and the surrounding soft tissue is carefully dissected to expose the device. The ultimate goal of this procedure is to ensure that the neurostimulator is correctly placed and functioning effectively, thereby enhancing the patient's quality of life by managing their chronic pain more effectively.
