I'm using Bonnie-Prior (https://bonnie-prior.healthit.gov) to create test cases for the CY2019 eCQM specs for Eligible Hospitals published in May 2018.

For the AMI-8a(CMS53v7) measure I added data for a patient which meets numerator. The measure calculation displayed is accurate (meets numerator). When I export the QRDA file it does not include certain data elements i.e. [Diagnostic Study Performed: ECG and Procedure Performed: PCI].

You can see that these data elements are there in the Exported Excel but not in the QRDA file.

 I have noticed such missing data elements in other measures as well - Bonnie-508 and Bonnie-509.
