I'm sure it's different from state to state and facility to facility. For example, let's say grandma fractures a hip and has to go to skilled nursing for a few weeks for care and observation. At which point can she go back to memory care, if at all? What does a memory care resident have to be able to do for themselves to stay in memory care?
The Memory Care where my Dad had lived, I noticed some patients were bedridden. The facility did offer physical therapy to their Memory Care residents and probably had programs for example if someone broke a hip.
If a resident went to the hospital (and rehab) full payment was due despite the fact that the resident wasn't there. The only option was to vacate the room and hope there would be an opening when needed. (And some contracts require a 30 day notice before vacating (and stopping the bills).
One issue described to me was an inability to handle an aggressive resident. From my observation, they tried very hard to work things out and keep most residents. Is there a particular concern you have?
