Hey Rose, have you tried contacting your local Medicaid office? or your State Dept of Human Services or Dept of Health?

I know your friend wants to stay at home and his condition doesn't sound that bad yet but just in case..my state has an adult foster home program for nursing level of care clients. It is a Medicaid-subsidized program. It keeps people out of institutions and the clients get to stay in a home-like environment. It's not everyone's cup of tea and it might not even be available in your state, but just thought I would share it as an option.
