Managed care programs administered by private health insurers have been available to Medicare beneficiaries since the 1970s, but these programs have grown significantly since the Balanced Budget Act – signed into law by President Bill Clinton in 1997 – created the Medicare+Choice program.
The Medicare Modernization Act of 2003 changed the name to Medicare Advantage, but the concept is still the same: beneficiaries receive their Medicare benefits through a private health insurance plan, and the health insurance carrier receives payments from the Medicare program to cover beneficiaries’ medical costs.
