CMS has sent the Medicare Shared Savings Program regulations to the Office of Management and Budget, one of the last stops prior to being published in the Federal Register.  The Medicare Shared Savings Program will govern the administration of Accountable Care Organizations (“ACOs”). The proposed rules, issued in March, contained 127 pages of details and 65 measures related to the formation of an ACO.  Based on the backlash from industry leaders, it is expected that the final rule will contain significant changes.
