According to CMS specification, numerator is met for this measure with below condition:
Numerator =
AND: Union of:
"Assessment, Performed: Standardized Tools for Assessment of Cognition (result)"
"Intervention, Performed: Cognitive Assessment"
<= 12 month(s) starts before end of Occurrence A of $DEMEncounters149 (Defined as a set of encounters during measurement period)

Bonnie only considers numerator met, if that assessment or intervention is performed within <=12 months from the encounter which is overlapping diagnosis. However, numerator condition on the measure specification does not mention that this documentation has to be fulfilled only within <= 12 months from the $DEMEncounter which overlaps the diagnosis. Please advise on how to proceed with this scenario.
