What 63650 covers
The clinician advances a neurostimulator electrode array through a percutaneous needle into the epidural space, positioning it to deliver spinal cord stimulation. Pain medicine physicians, anesthesiologists, and neurosurgeons commonly perform the procedure for patients with persistent pain, including during a temporary stimulation trial before a permanent system is considered. The lead may connect to an external stimulator during a trial or to an implanted pulse generator for ongoing therapy.
Report 63650 for percutaneous epidural array placement, rather than the open laminectomy approach in 63655. The operative or procedure note should support the percutaneous approach, epidural placement, and array work performed. Related postoperative visits during the 10-day global period are included. When multiple procedures occur in one session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

63650 billing questions
How is 63650 different from 63655?
63650 describes percutaneous placement through a needle. Use 63655 for epidural electrode placement through a laminectomy approach.
Can 63650 be reported with an implanted pulse generator code?
It may be reported with 63685 when percutaneous lead placement and pulse generator insertion are performed as part of the same permanent system procedure. A temporary trial typically uses an external stimulator rather than an implanted generator.
Should modifier 50 be appended for bilateral placement?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this service.
Are postoperative visits included?
Related postoperative visits during the 10-day global period are included in the procedure's payment.
Can an assistant surgeon or co-surgeon be billed?
Medicare does not pay an assistant at surgery for 63650. Co-surgeons and team surgery are not permitted.
What documentation supports 63650?
Document the percutaneous approach, epidural electrode array placement, and the clinical purpose, such as a spinal cord stimulation trial or permanent lead placement.
