Emergencies not covered

My father passed out last night, hitting his head in the fall. An ambulance was called to assist, but when we got to the hospital we were told that the hospital was not part of their network on their hospital plan. The paramedic phoned Bestmed and was given the hospitals that are in network, and was told that we had to pay for the emergency room fees, Dr's, medicine, and everything else that is done from the emergency room. We were told ARWYP is not part of the network even though this shows differently on Bestmeds online information. Surely as an emergency, the emergency vi8sit and ambulance etc should be covered? Bestmed was not helpful at all. What is the point of a hospital plan if they do not cover emergencies?
