      Thank you for the question on CMS529, Core Clinical Data Elements for the Hybrid Hospital-Wide Readmission (HWR) Measure with Claims and Electronic Health Record Data. Previously, many eCQMs and the Hybrid HWR Measures (CMS529) stated the age criteria logic using the 'Global.CalendarageInYearsAt' function, and restated the interval for birthDatetime. This function was removed from the Measure Authoring Tool Global Common Library to take advantage of capability within the CQL specification.
       
      This change streamlines the logic and also removes the datatype, 'Patient Characteristic Birthdate' and associated Birth date LOINC code from the human readable version of the measure. The revised age function accesses the birthdate element of the patient to retrieve the value using the model info and CQL-to-ELM (Expression Logical Model) translator.
       
      This logic change does not change the intent of the measure. The intent of the measure is still to include in the initial population all Medicare Fee-For-Service encounters age 65 and older at the start of an inpatient admission, as stated in the Measure Specifications.

      Hi Team,

       

      Consider statements below from CMS529v3:

       

      Inpatient Encounters
      ["Encounter, Performed": "Encounter Inpatient"] InpatientEncounter
      with ["Patient Characteristic Payer": "Medicare payer"] Payer
      such that Global."HospitalizationWithObservationLengthofStay" ( InpatientEncounter ) < 365
      and InpatientEncounter.relevantPeriod ends during day of "Measurement Period"
      and AgeInYearsAt(date from start of InpatientEncounter.relevantPeriod)>= 65

       

       

      Query #1:
      As we can see, in CMS529v3 the below statement has been removed as compared to CMS529v2-
      ["Patient Characteristic Birthdate": "Birth date"] BirthDate

       

      1. Does this affect the measure functionality in any way?

       

      Query #2:
      Global."CalendarAgeInYearsAt" has been replaced by 'AgeInYearsAt'. How to interpret the statement - AgeInYearsAt(date from start of InpatientEncounter.relevantPeriod)>= 65 ? Age needs to be checked on which date/s?

       

      Request you to provide us with the resolution urgently as our client deliverables are dependent on it.
