When submitting a patient generated from template Z29 VTE for C1/C3 testing it returns a warning message:
"Interval with nullFlavor low time and nullFlavor high time. Located in element with QRDA type: DeviceApplied and id: 188.8.131.52.4.1.115(root), 5f4585090dd67303329745f9(extension)"
This appears to be caused by a Device, Applied with only an Author DateTime and no high/low times or negation reasons which is not needed for determining the patient's measure status result.
Attached is the affected VTE-2 Test Deck (40_Terri_Perez) and corresponding Get Known Good Result (42_Terri_Perez) XMLs of the generated patients.
