2025 CPT code 61867
(Active) Effective Date: N/A Surgery - Surgical Procedures on the Nervous System Surgery Feed
Stereotactic implantation of a neurostimulator electrode array in a subcortical site (e.g., thalamus, globus pallidus) with intraoperative microelectrode recording; first array.
Modifiers may be applicable to indicate specific circumstances, such as increased procedural services (22), bilateral procedures (50), or reduced services (52). Refer to current CPT guidelines for proper modifier usage.
Medical necessity for this procedure is determined by the patient's specific diagnosis and the severity of symptoms.The procedure is typically considered for patients who have not responded adequately to medication or other less invasive therapies.
The surgeon is responsible for the entire procedure, from patient preparation and anesthesia to electrode placement, testing, and wound closure.This includes using stereotactic imaging, interpreting microelectrode recordings, and ensuring proper device function.
In simple words: A surgeon uses a special technique to precisely place a brain stimulator device into a specific area deep within the brain. A small hole is made in the skull, and the device is guided to the correct spot using 3D imaging. During the procedure, tiny electrical recordings are made to confirm the device is in the right place. This helps control certain movement disorders.
This procedure involves a twist drill, burr hole, craniotomy, or craniectomy for the stereotactic implantation of a neurostimulator electrode array in a subcortical site of the brain, such as the thalamus, globus pallidus, subthalamic nucleus, periventricular, or periaqueductal gray region.Intraoperative microelectrode recording is used to assist with precise placement of the array. This code is for the first array implanted.
Example 1: A patient with Parkinson's disease undergoes implantation of a deep brain stimulation electrode array in the subthalamic nucleus using stereotactic guidance and intraoperative microelectrode recording to control tremors and rigidity., A patient with essential tremor undergoes implantation of a neurostimulator electrode array in the thalamus to alleviate tremor symptoms using intraoperative microelectrode recording for precise placement., A patient with dystonia undergoes implantation of a neurostimulator electrode array in the globus pallidus with intraoperative microelectrode recording to improve motor control.
Documentation should include the operative report detailing the procedure, including the target site, the type of electrode array used, the use of intraoperative microelectrode recording, and any complications. Preoperative imaging studies and neurological evaluations supporting the medical necessity of the procedure should also be documented.
