This is the most succinct discussion of the so-called doc fix (change in the standard growth rate for Part B payments) that I have seen from Ezra Klein's blog. He both gets at what the SGR is, sets it in some context compared to other recent legislation, identifies the fact that addressing it has been delayed many times since 1998 (true bipartisanship!) and how it is not a persuasive means of attacking the reform bill just passed. Rep. Ryan was welcome to bravely lead the charge to fix the SGR back when Republicans controlled the House, Senate and White House.
In fact, it would be a great chance for the President to gain some cred on spending/deficits by proposing a long term SGR fix and paying for it. If you are looking for suggestions, wrap up some more med mal reforms, the estate tax along with this and go from there.
