"They would not release her to us for some unknown reason.
So I filed an appeal while waiting for her release."
If this is all documented......seems to me you will eventually be absolved of all expenses.
In no way am I an authority on the subject so just offering an opinion.
Sorry to hear of the aggravation on top of all the stress I know you must be going through, BK. If it means anything at all, I admire and respect you for looking after Mom!
Please give her a big hug from us!
