I'm just guessing here, but this sounds like a legal question. You have power of attorney and you want to know what your legal rights are under the law in regards to patient advocacy. You might want to consult an attorney in your area. Again, I'm just guessing, but I would say that laws regarding patient advocacy may differ from state to state. I wish I could be more help, but I would call a lawyer. Many will advise you free of charge.
