Pricing transparency, for whatever reason, does not exist as a rule in the medical industry. The "charge masters", are a joke that the hospitals themselves admit are useless as indicators of actual prices paid unless you're out of pocket, and then you get to pay them. Even then, the charge masters, as useless as they are, are still kept well hidden from all but the most inquisitive.
I hope you're right about the government not hindering medical pricing transparency. Now we need to get them to mandate it.
