Looking for additional clarification on: https://oncprojectracking.healthit.gov/support/browse/QKI-2

The solution provided on this Jira mentions:

    "For purposes of hospital measure calculation:
     1. If a relevantDatetime is reported, it will be converted to a relevantPeriod
     2. When a relevantPeriod is reported and a relevantDatetime is needed for evaluation, the low value will be used             unless not provided, then the high time will be used"

The example measure given was for CMS129 where both relevantdatetime and relevantperiod are used in the functions given in measure specs.

My question is specific to point 1 of the solution provided and how that applies to measures which only utilize the relevant period function.

Should vendors honor relevantdatetime as a substitute for the relevantperiod if measures do not explicitly leverage relevantdatetime in any of the functions on the measure specifications? 

For example, CMS134 Numerator Calls for:

( "Renal Procedures"
union "Renal Interventions"
union "End Stage Renal Disease Encounter"
union "Protein Urea Lab Test" ) ScreeningNephropathy
where ScreeningNephropathy.relevantPeriod during "Measurement Period"

If a urine protein test is found to have a relevantdatetime during the measurement period, but is missing the low and high values required for relevantperiod, should this datapoint be considered for numerator?
