CPT® Code 61868

Add-On Code

Twist drill, burr hole, craniotomy, or craniectomy with stereotactic implantation of neurostimulator electrode array in subcortical site (eg, thalamus, globus pallidus, subthalamic nucleus, periventricular, periaqueductal gray), with use of intraoperative microelectrode recording; each additional array (List separately in addition to primary procedure)

The procedure described by CPT® Code 61868 involves the implantation of a neurostimulator electrode array in the subcortical regions of the brain, which are critical areas for managing various functional disorders. This procedure is particularly relevant for patients suffering from conditions such as Parkinson's disease, different types of tremors, multiple sclerosis, medically intractable primary dystonias, and symptoms related to psychotropic medications. Additionally, it addresses issues like bradykinesia, dyskinesia, rigidity, and severe pain associated with cancer or other underlying causes. The process begins with the attachment of a stereotactic frame to the patient's skull, which is essential for precise navigation during the surgery. Advanced imaging techniques, such as MRI or CT scans, are utilized to meticulously map the brain, allowing the surgical team to determine the optimal locations for electrode array placement. The procedure may involve creating twist drill holes or burr holes to access the targeted implantation sites, with careful localization and marking of entry points on the skin. In some cases, a craniotomy or craniectomy may be performed to provide direct access to the brain. Throughout the procedure, the surgical team employs intraoperative microelectrode recording to ensure accurate placement and functionality of the neurostimulator arrays, ultimately aiming to achieve the best possible therapeutic outcomes for the patient.
