I own a house with my brother, but if either of us needs to go into a nursing home, is there a document that will protect the house?

I own a house with my brother in joint tenancy. If one of us has to go into the nursing home is there a document such as a trust that will protect the whole house so hospitals/nursing homes can't file a lien. I have asked several attorneys and come up with different answers. I live in MN. Some tell me to put in trust others says do nothing but I would think this is a questions that they are asked who should I believe.
