CPT® Code 95962

Add-On Code

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; each additional hour of attendance by a physician or other qualified health care professional (List separately in addition to code for primary procedure)

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 brain's surface or inserted into deeper brain structures 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 mapping is invaluable, as it guides the neurosurgeon in planning the subsequent surgical procedure, allowing them to navigate around critical brain structures effectively. The coding for this procedure includes CPT® Code 95961 for the first hour of mapping and CPT® Code 95962 for each additional hour of attendance by a physician or qualified healthcare professional, ensuring accurate billing for the time spent on this essential aspect of the surgical process.
