dannygirl,
I'm not involved in any controversy over this. I just want to point out that Kristi has correctly stated what that link says, as well as what our experience was.
Keep in mind that the hospital may take a while to sort out what you owe. That was our experience from a short hospital stay for my wife, who is actually British but was not ordinarily resident in the UK at the time. The hospital did not seem to be sure what to charge, and it certainly did not know how to deal with my US insurance cover. We eventually got a bill, and the hospital eventually got paid. In the end, everyone was happy.
