Medicare won't pay for my wifes electric wheelchair because she is on hospice. Any advice?

Another possibility is to check your local community's senior center to see if they have or are aware of a "loan closet" which has various assistive devices.

There is a possibility though that hospice may be uncomfortable with a chair that hasn't been ordered through them because of any potential liability issues. We ran into this situation, I believe when my father wanted to bring in his own walker.

Have you discussed this with the hospice nurse? Did she have the power chair before she went on hospice? I believe that this is the kind of equipment that is rented, rather than owned, and if she already has one then continuing the monthly payments is not a long-term investment. It may or may not be something that Hospice can cover, but I would certainly discuss it with them, and go through any appeal process if you need to. You might also see if you could make monthly rental payments to the vendor yourself, if you get turned down by Hospice and you feel this is a significant part of her quality of life at this time.

My heart goes out to you. It is heart wrenching to have a spouse on hospice. I am sorry you have this battle to fight on top of that. Whether you win or lose, being the best advocate you can be on her behalf is a loving thing to do.

Once you go on Hospice, all care and equipment needed goes through the Hospice agency and not your primary. The patient would not be expected to make use of a long-term investment item like a power chair.
