This is both hilarious and crazy.
It turns out that hospitals are completely capable of reporting prices over the phone. Ninety-five percent of facilities could tell you the price of parking. Only 15%, however, could give you the price of an ECG. The prices ranged from $137 to $1200. I have no idea how such a variance could be justified.
They also seemed to offer free or discounted parking almost all of the time. So they can be sensitive to consumer demand. Just, apparently, not for actual care.
