I was in the ER earlier this year. Had an ultrasound done and a BUNCH of labs. $500 copay for the whole visit and insurance eats the rest - regardless of where I am on my deductible.
I'd had the exact same ultrasound done "routinely" 2 days prior, at the same hospital, and similar lab the week before.. I had to pay about $1,300 for the privilege because that all falls to my deductible. (Insurance paid nothing)
So it cost me almost 3x as much to go during the day than it costs during the ER - but my insurance paid out about 6x as much for the ER visit. I wonder how many "ER Abusers" have figured out it's actually cheaper for THEM to go to the ER than "normal doctors"?
