Very little, only because I know very little. I tell them to find out, to call the person who does their taxes or call the 1-800 number to find out more about it. It would be great if clinicians had more information on how to direct people, but we don't have that readily accessible unless we dig for it.
The only thing I can tell people who are moving from one place to another is that, before they move, they'd better call and find out what coverage they're going to get when they get there.
