What 63664 covers
This service revises an implanted spinal cord stimulation paddle or plate electrode when the existing lead must be repositioned or replaced. The surgeon exposes the lead through a laminotomy or laminectomy to access the electrode; intraoperative imaging may be used. Neurosurgeons and orthopedic spine surgeons commonly perform the procedure in a facility setting for patients whose implanted paddle lead requires surgical correction.
Report 63664 for revision of the paddle electrode, not removal alone or work on the pulse generator. The operative report should identify the existing paddle lead and describe the revision performed, including the surgical exposure and whether the lead was repositioned or replaced. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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% multiple-procedure reduction. Modifier 50 is not appropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
