What 63663 covers
A surgeon revises an existing percutaneous electrode array used for spinal cord neuromodulation, repositioning or adjusting the lead and replacing it when needed. This work may be considered when a patient’s stimulation coverage changes or the array has shifted. Neurosurgeons and physicians specializing in pain procedures commonly perform the revision in an operating room or other procedural setting. Fluoroscopic guidance, when used, is included in the service.
Select this code for revision of a percutaneously placed array, not for removal alone, initial array placement, or revision of a surgically placed paddle array. The operative report should identify the existing array and describe the revision or replacement performed. Related postoperative visits during the 10-day global period are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
