The Center for Health Care Strategies (CHCS) prepared this compendium of Medicaid fact sheets to provide Aligning Forces for Quality (AF4Q) alliances with an overview of opportunities to improve health care quality presented by their state Medicaid program and its beneficiaries. It presents information on Medicaid nationally, followed by individual state Medicaid profiles for each of the 15 AF4Q communities. These fact sheets will be updated periodically to reflect ongoing changes in the Medicaid environment.
