Requiring explicit written consent to receive each service (after mandatory price disclosure) would also be welcome. I broke my ankle a few years ago, and half the bills sent to me I didn't recognize what they were for. In one particularly egregious example, some doctor literally spent less than 30 seconds near my ER bed, did not even look at the injury or the charts, and billed my insurance $700. And I've never seen him after that, received no prescriptions, no recommendations, and no treatment of any kind.
