Having been through several hundred thousand dollars of chargemaster charges with one of the hospitals on this list I can confidently say this info is not consumer-friendly at all.
First of all, did anyone look at the damn PDFs? Do you have any idea what a "HCHG SP EVAL MTN FLUOR SWAL 75" is or a "HCHG XR RIBS BILAT W PA CXR"? Does this really equip the typical healthcare consumer with the ability to "shop 'n save"? No. They are going to ask their health insurance provider if the hospital is in network, and the health insurance bureaucracy has the experts who pour through and negotiate all this crap.
Second, even if you had about a year of your life to educate yourself about the hundreds of myriad codes like this that are involved in various procedures and take it upon yourself to compare hospitals, this would be like comparing hotels based on their rack rate. You might get a sense for things but nobody pays that. Everything is negotiated down. Even for the uninsured who usually either get a 50%+ discount or pay whatever they can pay and kill their credit or go bankrupt. Which is not to imply in any way this is affordable for anyone, just that chargemasters aren't a super useful way to compare pricing even if you could figure it out.
Third, it's a free market fantasy that more "consumer" info will fix this system. Many patients are not in a position to comparison shop anyway. It is the epitome of a market failure.
If you want to fix this system we need Medicare For All.
