Now Available: Data Element Definitions for CMS eCQMs for 2020 Quality Reporting/Performance Period on the Collaborative Measure Development Workspace, Data Element Repository

October 10, 2019 - 10:45am

The Electronic Clinical Quality Measure (eCQM) Data Element Repository (DERep) located on the Electronic Clinical Quality Improvement (eCQI) Resource Center now includes information on the Centers for Medicare & Medicaid Services (CMS) eCQMs for both 2019 and 2020 reporting and performance periods. The DERep contains definitions for standardized eCQM data elements currently used in CMS quality and value-based programs and clearly presents data element definitions for all eCQMs used in CMS’s quality reporting programs. The DERep provides clarity for clinicians, quality measurement specialists, health information technology (IT) developers/vendors, and IT staff when representing and mapping data required for eCQMs used in these programs.

In December 2018, CMS expanded the eCQI Resource Center to include the Collaborative Measure Development (CMD) Workspace. The CMD Workspace brings together a set of interconnected resources, tools, and processes to promote clarity, transparency, and better interaction across stakeholder communities that develop, implement, and report eCQMs. The CMD Workspace includes a landing page, with information about the five planned modules housed in the Workspace, and the first module to go live, the DERep.  

Look for forthcoming communication on go-live timelines for the other planned CMD Workspace modules that will include: eCQM Concepts, New eCQM Clinical Workflow, eCQM Test Results, and automated updates on eCQMs under development. 

CMS encourages users to explore the CMD Workspace DERep and provide feedback at
