What 61864 covers

A neurosurgeon places an additional electrode array in a subcortical brain target for neurostimulation, using a twist drill or burr hole. This code is for an array beyond the first during the implantation procedure and describes the pathway without intraoperative microelectrode recording. Such electrode placement is commonly part of deep brain stimulation surgery for movement disorders, including Parkinson disease, essential tremor, or dystonia.

Report 61864 with the first-array code 61863 when the operative documentation supports an additional array placed during the same procedure. The note should identify the number of arrays implanted, the subcortical placement, the surgical approach, and whether intraoperative microelectrode recording was used. CMS classifies 61864 as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period.
