It looks like my Mom needs to go into assisted living. She has some savings but what happens when her money runs out?

I think your first step should be contacting Medicaid to see how and if mom is qualified. Once you have that information, you'll be in a better position to investigate possibilities.

Why is she under observation at the Hospital? What are her impairments? You say "they" are recommending 24/7 care, what level of care?

She doesn't qualify for Medicare funded rehab because she hasn't had a qualifying 3 night admission to a hospital. Can you talk to the discharge planners about next steps?

Often there is a social worker at the hospital who can give you some guidance, tell you who processes the Medicaid claims, and get the ball rolling. When you say savings, do you mean a couple hundred or thousands? What is her monthly income. There are guidelines on those. Depending on that, she may have to do spend down, which I cannot explain very well. Others here have done it and can help explain that. Good luck.

My mother is borderline and can not make it in assisted living, I fear for the staff and others because she is extremely aggressive and impossible. What are my o[tions?

Has she had an inpatient psychiatric evaluation to see if medication can help?
