I'm not so clear on how that works in the states. Here in Argentina you have a public system that everyone can use. Now, if you want, you can pay for private healthcare and use that if you think it's better, but the public system is still available even then, and there are no limits to what it covers. The public system doesn't care if you can pay it or not, or even if you're a national or a foreigner. Just walk in, show some ID, and you can use it.
