When a proposal to encourage end-of-life planning touched off a political storm over “death panels,” Democrats dropped it from legislation to overhaul the healthcare system. But the Obama administration will achieve the same goal by regulation, starting Jan. 1. Under the new policy, outlined in a Medicare regulation, the government will pay doctors who advise patients on options for end-of-life care, which may include advance directives to forgo aggressive life-sustaining treatment. Congressional supporters of the new policy, though pleased, have kept quiet. They fear provoking another furor like the one in 2009 when Republicans seized on the idea of end-of-life counseling to argue that the Democrats’ bill would allow the government to cut off care for the critically ill.
