Adult Health Care Quality Measures

Initial Core Set of Adult Health Care Quality Measures for Medicaid-Eligible Adults

The Affordable Care Act (Section 1139B) requires the Secretary of HHS to identify and publish a core set of health care quality measures for adult Medicaid enrollees. The law requires that measures designated for the core set be currently in use. To aid in the assessment of the quality of care for Medicaid-eligible adults, the law calls for HHS to:

  1. Develop a standardized reporting format for the core set of measures:
  2. Establish an adult quality measurement program;
  3. Issue an annual report by the Secretary on the reporting of adult Medicaid quality information;
  4. Publish updates to the initial core set of adult health quality measures that reflect new or enhanced quality measures.  

In January 2012, HHS published an initial core set of for voluntary use by Medicaid. These measures reflect the diverse populations served by Medicaid. 

Updated Adult Core Set 

The 2019 Adult Core Set was released in a November 2018 Informational Bulletin. Section 1139B of the Social Security Act, as amended by Section 2701 of the Affordable Care Act, notes that the Secretary shall issue updates to the Adult Core Set beginning in January 2014 and annually thereafter. CMS worked with the National Quality Forum's (NQF) Measures Application Partnership (MAP) to review the Adult Core Set and to identify ways to improve it. A background report contains information on the MAP's review process, selection criteria, and feedback to CMS.

The Adult Core Set includes several measures focused on behavioral health. These along with similarly focused measures from the Child Core Set have been identified as a Behavioral Health Core Set. Similarly, measures from the Adult and Child Core Sets’ focused on maternal and perinatal health have been identified as a Core Set of Maternal and Perinatal Health Measures for Medicaid and CHIP (Maternity Core Set).

State data derived from the core measures are part of CMS’s annual Child and Adult Core Set measure reporting, which includes publication of chart packs and datasets that highlight publicly reportable measures. 

How States Voluntarily Report Medicaid Adult Core Set Measures

States can voluntarily collect the 2019 Adult Core Set measures by using the 2019 Technical Specifications and Resource Manual. A summary of updates to the adult core set technical specifications and resource manual for FFY 2019 is also available.

Adult Medicaid Quality Measurement Program

By January 1, 2013, a Medicaid Quality Measurement Program will be established to fund the development, testing, and validation of emerging and innovative evidence-based adult health quality measures. As specified in the legislation, this program is to be established in the same manner as the Pediatric Quality Measures Program.

Technical Assistance and Analytic Support Program

CMS is committed to supporting states’ efforts to measure and improve the quality of health care for children and adults enrolled in Medicaid and CHIP. To increase the number of states consistently collecting, reporting, and using the Medicaid Adult Core Set measures, CMS established the Technical Assistance and Analytic Support (TA/AS) Program with an award of a contract to Mathematica Policy Research. Mathematica – teamed with the National Committee for Quality Assurance and the Center for Health Care Strategies – works with CMS to support states’ adult health care quality measurement and improvement efforts. The overarching goals are to increase the number of states consistently collecting and uniformly reporting the voluntary core measures set, and to help states understand how to use these data to improve the quality of care for adults. As part of the technical assistance effort, CMS will share promising practices for collecting the core measures with states. For more information, see the Technical Assistance and Analytical Support Program fact sheet.

Annual Reporting on the Quality of Health Care for Adults Enrolled in Medicaid

CMS annually releases information on state progress in reporting the Adult Core Set measures and assesses state-specific performance for measures that are reported by at least 25 states and which met internal standards of data quality. Information about performance on frequently-reported health care quality measures in the Adult Core Set is provided below, in addition state-specific quality information can also be viewed in the Quality of Care section of the State Medicaid & CHIP Profiles web page.
