The $716 billion in Medicare "cuts" that got so much attention in the presidential election have already begun sinking their teeth into healthcare providers. There are widespread jitters that any further cuts as part of a year-end deal to stave off sequestration or strike a "grand bargain" for a long-term fiscal deal would deeply gouge some providers, if not put them out of business. Providers say the stakes are higher than ever, and some are digging in their heels. The hospital industry stands to gain the most from the law's health insurance expansions. But it's also on the hook for about a third of the $716 billion in Medicare savings.
