Is there a way to challenge a medical power of attorney decision? If the mpoa decides to move the principle from a better facility to a lesser facility with less access to rehab, nursing and medical care resources which does not give the principle as good of an opportunity for stroke recovery, is there any way to challenge the decision and keep the principle in the better facility? Insurance is not an issue.
Are you sure that the 2nd facility is worse than the 1st? Is it worse in a way that would significantly affect the outcome of the principal?
Less access to rehab or less access to on-site amenities is NOT a good reason. I believe you are going to have to prove that facility #2 is not as good as facility #1 with hard facts like inspection reports or finding unfavorable clauses in the contract.
Regarding stroke recovery, the best way you can deal with stroke recovery is to be as hands-on as much as you can. If the move affected your ability to be as "hands on" as the previous facility, you might have a chance.
Last but not least. Challenging the decision of the MPOA through the "system" is going to cost money. Chances are that money has been spent for deposits and facility fees, etc. Do you really want to spend all that money on challenging a decision when it could be used for care of the principal? If the 2nd facility costs more than the 1st, then you have a chance to make the change from a financial point of view.
I would see if you could mediate/negotiate with the MPOA directly, before going the more costly route, a lawyer or a professional mediator.
P.S. A good facility does not guarantee that the principal will cooperate with what is needed for treatment. In fact, my mother hated the first rehab hospital that she went to because they forced her to walk and they forced her to do things that she didn't want to do. She liked the second facility better that allowed her to say no to PT, etc. At the 2nd facility, we were eventually denied Medicare coverage because she no longer was improving (because she refused to do the PT). Once we got her home, I forced her to do the PT, She improved enough to walk with a walker on her own. Neither facility was going to accomplish that because they had standards for what her age was capable of. They were content if she was bedridden. In their mind, she only needed to walk from her bed to the bathroom.
Did you ask? If so, what did the MPoA tell you?
If you didn't ask, please do. If you did and they didn't respond to you... you're out of the loop of authority and they're not obligated to tell you anything.
Second guessing is usually unhelpful on many fronts.
