In 2007 I was in Texas when I fell really sick. I was rushed to hospital because my throat closed up and walked out with a medical bill of $1,200. I had travel insurance but they where being difficult in paying the claim, so I never did. I am travelling to Hawaii in November this year and I am worried that I will not be allowed into the country due to my outstanding bill?
I know about people who did similar things due to insufficient insurance. No problem for you, especially in different state.
This is one of the reasons your bill was so high: hospital in USA is required to provide emergency care, but then is let high and dry to collect for provided services. You have to pay not only for you, but for many other people who choose not to pay (or could not afford to pay) for the services hospital was required to provide.
Get insurance from different company this time, and let internet know about that bad insurance so people can avoid it.
