One of my family members has had several hospital stays in the past two years. There were some charges that were considered outside the bounds of "usual and customary" by my insurance company. Are we required to pay those amounts that even the insurance thinks are too high? The insurance paid their portion of what they deemed appropriate but now the hospital is billing us not only the copay percentage but anything else that the insurance company rejected. Do we have any recourse? As a consumer this is really frustrating. It isn't as though prior to a surgery I can have any idea if the anesthesiologist might charge too much and if I can ask them to administer a little less gas to cut the cost.
