OK. You have a mentally ill person who needs to be in a hospital. Now, what?
Private hospitals will generally take most commercial insurance. They'll also take Medicare if it's not exhausted (Medicare allows for about 180 lifetime days in a private hospital. When those days are used the person must go to a medical surgical hospital.) Sometimes they'll take people with no insurance if they have an agreement with The Community Services' Boards for the area. Under some circumstances the tax payers of Virginia will pay the tab.
Some hospitals out of the area will not take someone unless you guarantee at discharge someone will pick them up.
If the person is retired military or a military dependent...well, there seems to be two kinds of TriCare or whatever they are calling it today. One type you must go to a military hospital if there is one nearby and they have a bed. The other type you may use anywhere.
Medicaid is only accepted at medical surgical hospitals. Well, that's not entirely accurate.. Medicaid allows younger people, I believe under 20, to go to private hospitals.
Ah, then there's FAMIS....not sure exactly what it is...but, seems to be sort of like Medicaid; however, you can only go to a medial surgical hospital. In fact, we're told that if a person with FAMIS goes anywhere else they lose their insurance.
Sooo, there you have it.... I think.
