Now Available: Updated eCQM Data Element Repository (DERep) for CY2023 Reporting and Performance Periods

July 21, 2022

The Centers for Medicare & Medicaid Services (CMS) has updated the Electronic Clinical Quality Measure (eCQM) Data Element Repository (DERep) to provide information for eCQMs used in CMS quality reporting and incentive programs for the calendar year (CY) 2023 reporting and performance periods. The eCQM DERep provides information on the data elements associated with eCQMs and their definitions. Each data element also includes the associated value set or the direct reference code (DRC), the Quality Data Model (QDM) datatype, the QDM attributes, and QDM entities used by that data element. eCQMs for 2023 reporting and performance period use QDM v5.6. The intent of the eCQM DERep information is to improve clarity for those implementing eCQMs.

Please send any comments, suggestions, or questions regarding the eCQM DERep to For more information on eCQM development and implementation, see the Electronic Clinical Quality Improvement (eCQI) Resource Center.
