What is CQL?

CQL is a Health Level Seven International® (HL7®) authoring language standard intended to be human readable. CQL provides the ability to express logic that is human readable yet structured enough for processing a query electronically. eCQM developers with access to the Measure Authoring Tool (MAT) and the Measure Authoring Development Integrated Environment (MADiE) can use the tool to author eCQMs using CQL.
