The Centers for Medicare & Medicaid Services (CMS) has updated the Electronic Clinical Quality Measure (eCQM) Data Element Repository (DERep) for the calendar year (CY) 2027 reporting and performance periods.

The eCQM DERep provides detailed information about the data elements used in eCQMs that support CMS quality reporting and incentive programs. For each data element, the DERep includes:

• A description and clinical context
• The associated value set or direct reference code (DRC)
• The Quality Data Model (QDM) datatype
• Related QDM attributes and entities

eCQMs used for the CY 2027 reporting and performance periods are based on QDM version 5.6. To learn more about eCQM development and implementation, visit the Electronic Clinical Quality Improvement (eCQI) Resource Center.
