Funny thing is: if you tell the hospital that you do not have an insurance they will charge you a price that actually sounds reasonable, say $700 for a CT scan (which is still like 2x more than in my home country, but then the US is a high cost of living place), but if you do have insurance they will try to extort as much money as possible from your insurer: initial bill will be like $10k, and then they will settle for, say, $6k.
