Unable to follow Performance Rate Guidance for Continuous Variable measures without further clarification
-
The "Supplemental Requirement to the 2014 CMS QRDA III Implementation Guide for Eligible Professionals for Performance Rate Calculation" states the following:
With this change, please note that the performance rate template is required, regardless of whether the measure being reported is a proportion measure or a continuous variable measure.
When reporting continuous variable measures, the performance rate can be nulled by using a @nullFlavor="NA" in the value element: <value xsi:type="REAL" nullFlavor="NA" />.
An issue that's not addressed by this guidance is that the performance rate template also requires the ID of the numerator of the referenced eMeasure as part of an externalObservation reference. Since continuous variable measures don't contain numerators what should be supplied in the externalObservation of the reference section of the Performance Rate template? Per the CMS QRDA Supplementary Implementation Guide for 2015 the reference and observation are required in this template.
