Exploratory Opening of the Skull

Wisconsin rates for HCPCS 61304

The skull is opened so the brain can be inspected directly when the cause of a problem cannot be established any other way, for example after a severe head injury or when bleeding or swelling is suspected. This version covers the large upper part of the brain. Whatever is found can then be dealt with during the same operation.
