Hello, Bozdickens. I assume you mean a mental hospital. It's hard to say, but I'd think whatever caused the hospitalization is still being treated. Could be all sorts of disorders.
I'm not sure about insurance. The most I've been in the hospital is two weeks or so, if I recall correctly. I would think insurance would cover treatment for a good while.
Who's been in the hospital that long around here? What can you tell us?
