Coverage in case of emergency is called "catastrophic coverage." If that's what you want, it's available on the health insurance exchanges for anyone under 30.

Coverage in case of emergency is called "catastrophic coverage." If that's what you want, it's available on the health insurance exchanges for anyone under 30. In my zip code, plans start at $90/mo for a 26yo with no family. (In comparison, bronze plans start at $133/mo.) If you'd rather bet that you won't get an expensive injury (a dangerous idea, in my opinion—emergency health care is expensive in the US), you can just pay the no-insurance fine. But it's not the way I would go.
