The Department of Health and Human Services (HHS) has published a notice with comment period that identifies an initial core set of health quality measures for Medicaid-eligible adults, as required by the ACA. The measures will be available for voluntary use by state Medicaid programs, health insurance issuers and managed care entities that contract with Medicaid, and Medicaid providers. The notice solicits comments on the initial measures, facilitating the use of the measures by states, and identifying priority areas for measure enhancement and development. Comments will be accepted until March 1, 2011.
