Data Element Catalog

The Data Element Catalog (DEC) was an eCQM value set metadata file in use from August, 2012 through May, 2017. NLM no longer creates the DEC file as of September, 2017. NLM Value Set Authority Center (VSAC) replaced the DEC with a more detailed metadata file called the Binding Parameter Specification. The DEC metadata file identified data element (value set) names required for capture in CMS eCQM electronic health record (EHR) technology certified under the 2014 Edition of the Office of the National Coordinator for Health Information Technology (ONC) Standards and Certification Criteria.
