Skull Surgery to Repair a Brain Fluid Leak

Montana rates for HCPCS 62100

The skull is opened so the surgeon can find and seal a leak of the fluid that surrounds the brain, repairing the tough membrane that normally holds that fluid in. It covers leaks that escape into the sinuses and drip from the nose, and leaks that drain from the ear. Sealing the tear stops the fluid loss and closes off a route for infection.
