What 63685 covers
This service places or replaces the implanted pulse generator or receiver that powers a spinal cord neurostimulator. The surgeon creates or accesses a pocket, commonly in the flank or buttock, and connects the generator to the stimulation leads. Neurosurgeons and pain physicians commonly perform the procedure in an operating room, including after a successful temporary stimulation trial or when an implanted generator needs replacement.
Report the generator or receiver service for the implanted power unit; lead implantation is a separate service when performed and coded. Operative documentation should identify whether the unit was newly implanted or replaced, the pocket work, and its connection to the stimulation system. Related postoperative visits for 10 days 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 for this descriptor and anatomy. Medicare may pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

63685 billing questions
How is this different from spinal electrode implantation?
This code covers the implanted generator or receiver in its pocket. Codes 63650 and 63655 describe spinal electrode implantation, not the generator.
Can the generator and lead procedures be reported together?
Yes, when both the generator or receiver and spinal electrodes are implanted during the encounter, report the applicable code for each service, subject to applicable edits.
When should 63688 be considered instead?
Use 63685 for insertion or replacement of the generator or receiver. Code 63688 describes revision or removal of that implanted component.
Should modifier 50 be appended for a generator on each side?
No. CMS identifies modifier 50 as inappropriate for this descriptor and anatomy; report the generator service without bilateral reporting.
What documentation supports reporting this code?
Document whether the generator or receiver was newly placed or replaced, the pocket procedure, and its connection to the spinal stimulation system.
