Great, now just do the same thing for making all hospitals in the state (and later the nation) forced to bill at "in network" rates. then with a final step of capping the premiums paid according to income with the rest automatically covered by social programs, the USA might finally get to something sort of like a sane healthcare system.
Last time my wife went to a hospital in California, they delayed care by like half an hour over insurance and then didn't use it, so she got to spend a few days on the phone half a year later when each doctor who managed to visit the room for a few seconds sent us separate bills at the uninsured rate.
In California, this shouldn't happen. If you go to an in-network hospital, all care providers you see are required to bill you at the in-network rate.
