Hidden Costs of Medicare Advantage

President Obama has proposed cutting more than $100 billion in subsidies over 10 years, a contentious component of health-care reform that will be fought in earnest as the bills move through Congress. But unlike some issues that touch off partisan sparring, Medicare Advantage has an unlikely band of bipartisan defenders who have already battled to restore $10 billion of the proposed reductions. In a health-care debate defined by big numbers and confusing details, the prospect of losing benefits such as a free gym membership through the Silver Sneakers program is tangible, and it has spooked some seniors, who are the nation's most reliable voters and have been most skeptical about reform.
