File a complaint with Health and Human Services [1]. It is clear they are not acting in good faith. Take snapshots of the URL with the Internet Archive for notarization [2].
Thanks for posting this. I just looked to see if my local hospital had prices available. They have a webpage set up, but they give you a dummy link! Outrageous! I will absolutely be making a complaint.
I'm also going to post a review online, since poor reviews seem to get attention from them.
