Senate Minority Leader Harry Reid did not commit to supporting an emerging Medicare “doc fix” bill at his weekly news conference Tuesday, as House Minority Leader Nancy Pelosi and Speaker John A. Boehner continue work on changes to the payment formula for Medicare doctors ahead of March 31, when payments would be cut by 21 percent. “They don’t have a rule yet, the SGR is still a work in progress and I personally am going to wait until we see it, having passed the House, before we start speculating on what we need to do with it, if anything,” Reid said.
