The same way anyone else does you go to the hospital. They are required to provide anyone with medical care especially in emergency situations.
Many hospitals in the us simply offer these kinds of medical things for free, if one qualifies.
The difference is at the end of the medical procedures one could get slapped with a medical bill… That one can discard outright. Medical dept is more often than not forgiven or forgotten by the hospital. It could be reported on your credit history but that is also often times overlooked or not calculated by the credit reporting agency.
America basically has universal healthcare. Of course there are very serious situations concerning long term care and unorthodox or experimental procedures that can be denied if they aren’t paid for.
And don’t get me wrong the health care system in America is a travesty and a human and civil rights issue that needs to be resolved!
I’m just saying you’re not gonna die if they can help it.
