Exposure Of The Front Skull Base Outside The Lining

Massachusetts rates for HCPCS 61582

Covers the surgical exposure needed to reach the front of the skull base, made by opening the skull above the eyes, lifting the frontal lobe while leaving the tough membrane covering the brain closed, and cutting through the bony floor beneath. Staying outside that membrane keeps the fluid space around the brain sealed. Treating the tumor or defect found there is billed separately.
