Brain Wave Monitoring During Non-Brain Surgery

Maine rates for HCPCS 95955

This service records and monitors brain wave activity using electrodes on the scalp while a person undergoes a surgery that does not involve opening the skull, such as an operation on the arteries in the neck. It helps the surgical team detect early warning signs that blood flow or oxygen to the brain may be reduced during the operation, so they can respond quickly. The monitoring continues throughout the relevant portion of the surgery.
