HCPCS 61867

Craniectomy or craniotomy for implantation of neurostimulator electrode, cerebral, in subcortical site (eg, thalamus, globus pallidus, subthalamic nucleus, periaqueductal gray), with microelectrode recording; first array

AI EXPLANATION: Deep brain stimulation electrode implantation is a surgical procedure where a surgeon creates an opening in the skull to place a thin, insulated wire into a targeted area deep within the brain. During the operation, specialized electrical recording instruments monitor and map brain signals to ensure precise placement of the electrode, which will later deliver electrical pulses to help manage symptoms.
