I knew full well the ER visit was going to sting, but I had no idea how much. The amount after insurance was almost exactly what was quoted in this article (almost like they plan that). That pretty much maxed out his OOP max, but I'm not wealthy enough that 5k doesn't make me mad. It shouldn't matter, but it feels worse that it was just a stomach bug, so $2 worth of anti nausea meds (that the hospital charged $150 for) was all we got out of it.
Rationally, I don't really see a way out for (possible) emergencies. That care is expensive, and HDHPs are a bit of a gamble that usually pay off if you're healthy. The OOP max ensures you won't be financially ruined, and 'cadillac plans' or gov care just means you pay far more in premiums or taxes for the majority of the years.
