Members of the U.S. Senate and House of Representatives will be meeting this month to put together a final health care reform bill. The Senate passed its version on Christmas Eve. The House had already passed its bill. But there are some pretty big differences between the two. One of them: cost. The Senate bill checks in at $871 billion. The House version: Over $1 trillion. Another issue: the so-called public option, a government-run health insurance program. House bill includes it; Senate bill doesn't. So, some compromises need to be made to come up with a final bill. And since that then has to be approved by both Houses of Congress, there are some concerns about whether it will pass.
