Headline: CPT code 61863 defines stereotactic placement of a subcortical neurostimulator electrode array without intraoperative microelectrode recording

CPT code 61863 represents a stereotactic neurosurgical implantation in which a portion of the skull is opened or a burr hole created to place a neurostimulator electrode array in a subcortical target without microelectrode recording. The procedure is used to treat chronic, difficult-to-control movement disorders such as tremor, dystonia, involuntary movements, and Parkinson’s disease. Its clinical importance stems from its role in advanced, device-based management of movement disorders when medical therapy is insufficient.
