Five years after it exploded into a political conflagration over "death panels," the issue of paying doctors to talk to patients about end-of-life care is making a comeback, and such sessions may be covered for the 50 million Americans on Medicare as early as next year. Bypassing the political process, private insurers have begun reimbursing doctors for these "advance care planning" conversations as interest in them rises along with the number of aging Americans. People are living longer with illnesses, and many want more input into how they will spend their final days, including whether they want to die at home or in the hospital, and whether they want full-fledged life-sustaining treatment, just pain relief or something in between.
