By signing the Balanced Budget Act of 1997 (BBA) on August 5, 1997, President Clinton made the most significant changes to Medicare, since its inception in 1965, by adopting market-driven reforms in an effort to balance the federal budget. One of the most significant Medicare reforms in the BBA was the creation of the Medicare+Choice program that provides Medicare beneficiaries access to a wide array of private health plan choices as well as traditional fee-for-service (FFS) Medicare. In addition, Medicare+Choice enables Medicare to further utilize delivery innovations, including preferred provider organizations (PPOs), openended health maintenance organizations (HMOs), point-of-service plans, provider sponsored organizations (PSOs), integrated delivery systems (IDSs) and primary care case management, that have helped the private sector contain costs and expand health care delivery options.
