I agree, I've never seen a one line EOB and a measly $48 discount, it makes me think there may be more bills coming unless they now lump whatever happens in the ER into a single charge.
I do remember back in 2017/2018 when I was still working Anthem sent out letters to everyone letting them know that they were reducing benefits on ER charges for non emergency care. We were all very upset because neither the company or Anthem would provide a detailed list of what would and would not be considered an emergency.
Needless to say they took a lot of flack about it and may have made some minor changes to the policy. I'm not sure if this applies to the OP's situation but it might.
Regardless, I would have your daughter call and negotiate with them and don't agree to any kind of payment plan. She wants a cash price to pay it on the spot or they can go pound sand. Tell her to threaten to post the bill on Facebook and other social sites, neither Anthem nor the hospital will want that publicity
