About 61863: Subcortical neuroelectrode implantation without recording
Reports stereotactic placement of a subcortical neurostimulator electrode array without intraoperative microelectrode recording, commonly for deep brain stimulation.
A functional neurosurgeon uses a twist drill or burr hole to place a neurostimulator electrode array in a subcortical brain target. This approach is used for deep brain stimulation, including treatment plans for movement disorders such as Parkinson disease, essential tremor, or dystonia. The code distinguishes placement performed without intraoperative microelectrode recording from the related technique that uses recording. It describes intracranial electrode placement, not implantation of the pulse generator or extension system.
Report 61863 for the first array when the operative record supports subcortical placement without microelectrode recording; use the additional-array code when another array is placed in the same applicable procedure. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61863 billing questions
When is 61863 chosen instead of 61867?
Use 61863 for subcortical array placement without intraoperative microelectrode recording. When the operative technique includes that recording, 61867 is the corresponding first-array code.
Does 61863 include the pulse generator?
No. It reports placement of the intracranial subcortical electrode array; a separately performed pulse-generator or receiver implantation may be reported with the applicable code, such as 61885.
How is a second array reported?
When another array is placed in the same procedure without microelectrode recording, report the applicable additional-array code, 61864, with 61863.
How is bilateral placement reported?
For bilateral work, report modifier 50; CMS payment for this code with modifier 50 is 150%.
What documentation supports 61863?
The operative report should establish subcortical electrode-array placement, the number of arrays, and that intraoperative microelectrode recording was not used.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days.
