My dad lives in a Residential Care Facility and has run out of money. He now has been Medi-Cal approved. How do we get him moved to a Medi-Cal nursing home?

My dad has dementia, is unable to walk. He lives in his bed and/or his chair. He fell in July and had too much money in their savings account to qualify for Medi-Cal. So he was discharged from the hospital to a private pay RCFE (Residential Care Facility for the Elderly) in California and the care is great there. My parents have now spent all their small savings on his care and he now qualified for Medi-cal. I am being told he must be admitted to the hospital to get in the system to be moved to Medi-cal facility. If we move him home where my 81 year old mother lives, he needs so much care that she can not provide, that he will fall (he forgets he can not walk) and my mother will need to call 911 and then he will be in the system? This is all so very emotionally stressful for my mother. This is so confusing. My mother can not care for him and does not have enough money to pay for care givers. He will be evicted from private pay RCFE  12/15! Not sure what to do next.
