If you have pudding accident, but have to pay out of pocket for medical repair of inside of you, then don't get worried, this stuff is pretty easily handled. First thing to do is call the hospital business office. Tell them you want to talk to someone about your bill. Don't tell them you can't pay quite yet, but question every item on your bill - often there are things on there that they will take off. Now tell them you can't pay the bill. The person there will guilt-trip you and imply that it is not their problem, but is very much their problem. Don't worry about this part and never let the person make you feel bad, because that person is specifically hired to try to extract money from people.
What will happen next is like trying to buy a car in reverse. Once the person realizes you actually can't pay, they will ask you what you can pay, usually offering to wipe out the bill entirely if you pay a reduced amount. This is definitely worth considering if you have a relative or friend you can borrow cash from. If not, ask about any assistance programs they offer, which will usually be none unless the hospital has a "St." in its name. These can often pay your entire bill for you after a little paperwork. The last thing to do is just tell them that you can only afford to pay $25 a month - for emergency care they are required to accept any payment you give them as long as you keep sending the amount to them. Of course this doesn't erase the debt, but it will keep it out of collections until you save up enough to pay.
As far as continuing care, look up local free clinics. Most aren't really free, they just charge on a sliding scale. Some are surprisingly nice and have very good local doctors who do their charity work there. You are still super-duper fucked if you have anything that requires any major procedures, however. You might want to look at reorganizing your bills and getting some private insurance before you're officially diagnosed with anything - insurance companies can still deny for pre-existing conditions for a few more years. Just be aware that private insurance has become much more expensive in the past year so get ready for some sticker shock.
