CMS149v6

As per the measure specifications for numerator Condition, the Assessment/ Intervention has to be performed during <=12 months starts before end of Occurrence A of $DEMEncounter149.

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

As per the Bonnie tool, ‘<=12months starts before’ is interpreted as 12months+ 29days.

Scenario1:

Intervention performed during 12months+29thday

Occurrence A of $DEMEncounter149 on 1/1/2012

Intervention performed during <=12months  on 12/02/2010 – is satisfying the Numerator criteria.

Scenario2:

Intervention performed during 12months+30thday

Occurrence A of $DEMEncounter149 on 1/1/2012

Intervention performed during <=12months  on 12/01/2010 – is NOT satisfying the Numerator criteria.

Given the above scenarios, what exactly should be our time frame for this numerator condition. For <=12months, should we consider exactly 12months only OR (12months+29days)?
