Once a nursing home patient is approved for Medicaid, what is the possibility of moving the patient to another facility?

My mother, who has Alzheimer's, now is having problems swallowing her food. I have already called the Ombudsman due to issues at this medicaid nursing home. Not enough staff, poorly trained staff, etc.. This nursing home is close by and I can visit my mother every day. However, the care is not always adequate and I have lost more than a few days of sleep when issues arise. At this point, I have also talked to her doctor regarding the care. Her doctor is affiliated with this nursing home. I believe the care has also had an affect on the Alzheimer's. At this point, I'm debating whether I should even call hospice. Once a patient is on medicaid, does any one know the possibility of transferring a patient to another medicaid facility?
