Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 61863 covers

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.
