On May 12, 2011, the House Energy and Commerce Committee Subcommittee on Health approved H.R. 1683, the State Flexibility Act of 2011, legislation to repeal the maintenance of eligibility requirements first implemented by the American Recovery and Reinvestment Act and later extended and expanded in the ACA.  The Congressional Budget Office (CBO) estimates that Medicaid spending would decline by roughly $1.5 billion over the period of 2012-2021, and CHIP spending would decline by approximately $8.8 billion over that period, as states tighten eligibility standards.
