eCQM Value Sets for 2021 Reporting Available in VSAC

NLM VSAC Publishes Updated Electronic Clinical Quality Measure Value Sets for 2021 Reporting


On May 07, 2020, The National Library of Medicine (NLM) Value Set Authority Center (VSAC), in collaboration with the Office of the National Coordinator for Health Information Technology (ONC) and Centers for Medicare & Medicaid Services (CMS), published the eCQM annual update for the 2021 reporting period for Eligible Hospitals and Critical Access Hospitals (CAH), and the 2021 performance period for Eligible Professionals and Eligible Clinicians. CMS updates the specifications annually to align with current clinical guidelines and code systems, so they remain relevant and actionable within the clinical care setting. These updated eCQMs are used to electronically report 2021 clinical quality measure data for CMS quality reporting programs. Measures will not be eligible for 2021 reporting unless and until they are proposed and finalized through notice-and-comment rulemaking for each applicable program.

Where to Find the Updated eCQM Measure Specifications

The updated eCQM specifications are available on the eCQI Resource Center for Eligible Hospitals and Critical Access Hospitals and Eligible Professionals and Eligible Clinicians under the 2021 Reporting/Performance Year. Other eCQM resources, including the Guide for Reading eCQMs, eCQM Logic and Implementation Guidance, tables of eCQMs, and technical release notes, are also available at the same locations. The Guide to Reading eCQMs and eCQM Logic and Implementation Guidance have been updated based on end user feedback and CMS continues to update these guides to assist stakeholders in understanding and implementing eCQMs.

Pre-Rulemaking Information

The eCQI Resource Center includes information about CMS pre-rulemaking eCQMs. CMS pre-rulemaking eCQMs include measures that are developed, but specifications are not finalized for reporting in a CMS program. At this time, there are two pre-rulemaking eCQM for Eligible Professionals and Eligible Clinicians and no pre-rulemaking eCQMs for Eligible Hospitals and Critical Access Hospitals. These measures will not be eligible for CMS quality reporting until they are proposed and finalized through notice-and-comment rulemaking for each applicable program. Please visit the pre-rulemaking eCQM pages for Eligible Hospitals and Critical Access Hospitals and for Eligible Professionals and Eligible Clinicians to learn more. The pre-rulemaking eCQM value sets for use in the pre-rulemaking eCQMs are available through the VSAC.

Hospital Hybrid Measures Information

The eCQI Resource Center includes information about CMS hybrid measures for eligible hospitals and critical access hospitals. A hybrid measure is a quality measure that uses both claims data and clinical data from electronic health records (EHRs) for calculating the measure. Please visit the new hybrid measures page on the eCQI Resource Center to learn more. The hybrid measure value sets for use in the hybrid measures are available through the VSAC.

Quality Data Model Update

CMS has published a guidance update for the Quality Data Model (QDM) version 5.5. The referenced document clarifies some of the definitions and fixes minor errata noted in the document initially published to the eCQI Resource Center in August 2019.
