I'm trying to understand how eCQM’s QDM Data Elements listed in the html provided with each eCQM map to actual QRDA Cat 1 measure entries.
For example, do all six Medication, Discharge listed for CMS100v5 in the QDM section actually map to six Discharge Medication (V3) urn:hl7ii:2.16.840.1.113883.10.20.24.3.105:2016-02-01 QDRA Cat 1 entries? What if a particular EHR/EMR does not have data for all six Discharge Medication or other QDM entries listed for eCQM, can such entries be safely omitted?
