CPT® Code 95961

Functional cortical and subcortical mapping by stimulation and/or recording of electrodes on brain surface, or of depth electrodes, to provoke seizures or identify vital brain structures; initial hour of attendance by a physician or other qualified health care professional

Functional cortical and subcortical mapping is a specialized neurosurgical procedure aimed at identifying critical areas of the brain that control essential motor and sensory functions. This process is crucial for ensuring that surgical interventions do not inadvertently damage these vital regions. During the procedure, the patient is typically sedated, and a craniotomy is performed to access the brain. Once the area of interest is exposed, the patient is awakened to allow for real-time mapping of brain activity. Electrodes are strategically placed on the surface of the brain or inserted into deeper brain tissues to stimulate specific regions. This stimulation helps provoke seizures or elicits responses that indicate the function of various brain areas. The information gathered during this initial hour of mapping is invaluable, as it guides the subsequent surgical procedure, allowing the surgeon to navigate around critical structures effectively. The CPT® Code 95961 is specifically designated for reporting the first hour of this mapping process conducted by a physician or other qualified healthcare professional, while additional hours of mapping are reported using CPT® Code 95962.
