When did CQL replace the expression logic portion of the QDM?

QDM versions prior to v.5.3 included both the conceptual data model (the categories and their context of use) and the expression logic to state eCQM clauses. QDM versions since v.5.3 include only the conceptual data model. This change occurred with eCQMs designed for the 2019 reporting/performance period when eCQM developers started using CQL to express logic. Download current versions of the QDM from the eCQI Resource Center QDM About tab.
