Each spring, the White House releases budget recommendations and plans for the government agencies, and by fall, it's up to Congress to decide what the appropriations laws will actually be.
(For example, the President can "announce" a tax on billionaires, but it's entirely up to the Hill to actually pass it.)

On the CMMI side, a diabetes prevention program has been on extended status as a pilot program, but would be made permanent, just like any other benefit. A judicial proposal would allow more appeals (ALJ system) to be "on the record" rather than court. Medicare would be part of a national program to "eliminate hepatitis C" in as much as these drugs would be copay-free.
