Fortunately, (or unfortunately, depending upon your point of view) the US is a generous country and won't let you die or suffer in pain on the hospital lawn. You will be billed for the services, and the cost will be astronomical. However there are no debtor prisons or medieval torture chambers to encourage you to pay. So if you are OK with taking advantage of the taxpayers in the country you are visiting you are good to go. It is being irresponsible and selfish, but when has that ever stopped anyone from getting what they want.
