Is Medicaid paying for her care? If so, call her caseworker and find out how it will work from County to County. Each County handles their own Medicaid. When hunting for a place for Mom, if I had gone into the next County, I would have had to apply for Medicaid in that County..
If she is private pay, that makes things better. With both instances, you find a new place and talk to them about transferring Mom. Transferring the first of the month. Not sure if there is any pro-rating done especially if on Medicaid.
I don't know about the county component but when I moved my MIL, I called the place I wanted to move her to and they pretty much took care of everything to arrange it. They had a motivation to get her there ASAP so she could start paying them instead of her prior SNF.
