Some unplanned medical tourism including an emergency appendectomy:
"Our insurance doesn’t cover us when we’re overseas, so we ended up paying out of pocket for all of it. That thought scared me at first, but all told, our bill was, conservatively, about 1/30th what we would have paid out of pocket in the US. In fact it was considerably lower than what we would have paid in copays in the US even *with* insurance."
It doesn't have to be like this.
