When it comes to Medicare and Medicaid, the debt deal raises more questions than it answers. The giant health care programs serving some 100 million elderly, low-income and disabled Americans were spared from the first round of cuts in the agreement between President Barack Obama and congressional leaders. But everything’s on the chopping block for a powerful new congressional committee that will be created under the deal to scour the budget for savings. And if that hunt leads to a dead end, the agreement decrees an automatic 2 percent cut to Medicare providers such as hospitals. That’s on top of a 6 percent cut already enacted to finance Obama’s health care law, which is just being phased in.
