More than three decades ago, emergency rooms could kick you out if doctors didn’t think you could pay. You might be suffering from a stroke, a gunshot wound or a broken spine, but if your insurance wasn’t good enough, many hospitals could slam the door in your face. This hot-potatoing of patients caused gruesome and unnecessary deaths before the practice was outlawed in 1986. Today, if you go to the hospital with an emergency, doctors pretty much have to treat you. If you have insurance, great. But even if you can’t pay, they’ll patch you up all the same. You’ll just leave the hospital with potentially crippling medical debt.
