CMS’ mission is to ensure health care security for beneficiaries. A major component in achieving this mission is the successful administration of Original Medicare, or Fee-for-Service (FFS) Medicare. Medicare Contracting Reform (or section 911 of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003) is a major component in achieving this mission. Section 911 mandates that the Secretary for Health & Human Services replace the current contracting authority to administer the Medicare Part A and Part B FFS programs, contained under Sections 1816 and 1842 of the Social Security Act, with the new Medicare Administrative Contactor authority. Through the implementation of Medicare Contracting Reform, CMS will establish a premier health plan that allows for comprehensive, quality care and world-class beneficiary and provider service.
