My understanding is they conduct a consult with an occupational therapist and they are the one who decides what aids to daily living are required.
One of the problems I had was the occupational therapist recommended things that would cause substantial devaluation of my house. For example, they wanted to put an elevator lift in my back yard, but to do this, they wanted to concrete my back yard. I don't know anyone out there who wants a concrete back yard. I certainly did not. That would really have affected the resale of my house if I had to move on.
So there are some difficulties with that, but it seems like if there is a need for it, it can get delivered, but whether or not it'll be delivered in a timely fashion is the issue.
