"Take a provision in the Baucus bill that would punish any physician whose "resource use" is considered too high. Beginning in 2015, Medicare would rank doctors against their peers based on how much they cost the program—and then automatically cut all payments by 5% to anyone who falls into the 90th percentile or above. In practice, this rule will only apply to specialists.
Since there will always be a missing chair when the music stops, every year one of 10 physicians will be punished if he orders too many tests, performs too many procedures or prescribes too many drugs—whether or not the treatments result in better patient outcomes. The 5% fine is substantial given that Medicare's price controls already pay only 83 cents on the private dollar."
