The chairmen of the U.S. House Ways and Means and the Senate Finance committees want to phase out the way Medicare pays doctors for their services. They're proposing a gradual change to a new system along with a pay freeze and incentives to give up fee-for-service billing. "Enough with the quick fixes. Our proposal is for a new physician payment system that rewards value over volume," Senator Max Baucus of Montana said in a statement. "It will go a long way in improving the efficiency and quality of care for America's seniors."
