The key point of prices being published in a machine accessible and machine readable format isn't the numbers. What numbers are published can be haggled over in future laws. But the requirement for some numbers to be published is a big win. FWIW, the move to digital health records was basically realized through Medicare demanding it. Providers can't afford to go without Medicare payments; like Texas and California, so goes Medicare, so goes the market.
