Adrianna's gall bladder surgery

My daughter, Adrianna, is scheduled to have her gall bladder removed on November 18, 2016. She has health insurance through my work for most of the cost. I received a call yesterday inforiming me that I have to pay 1/3 of the fee for the facility the surgery will be performed at before the 18th. If I had been given more notice, that wouldn't have been a problem but the surgery is next Friday and I am her sole financial provider right now. Please help if you can. I would really appreciate it.
