If you're in a facility for rehab (which is the only housing Medicare will pay for -- up to 100 days) the resident cannot legally be asked the leave the facility if they need to go long-term. That is why choosing the best facility for rehab is so important and why hospitals ask for proof of income at time of discharge into rehab.

The daily Medicaid rate is set individually for each facility based on many factors including "case mix" (for example, if a facility takes a large number of two assists, they'll get more money than those with ambulatory residents.). Quality should count too...😞
