What 63661 covers
This procedure removes percutaneously placed epidural leads from a spinal cord stimulation system. Neurosurgeons and pain specialists commonly perform it when leads have migrated, fractured, become infected, or are no longer needed. The code concerns the electrode array, not removal or replacement of the pulse generator in its pocket. Fluoroscopy, when performed, is included in the service.
Report 63661 when the percutaneous array is extracted; use a revision code when the lead is repositioned or otherwise revised instead. The operative note should identify the percutaneous approach and document which leads were removed and why. Related postoperative visits are included in the 10-day global period. For multiple procedures in one 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 available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
