Solution: ​Thank you for your inquiry for CMS156v11 (2023 performance period). Please note that the response will be provided in the context of CMS156v11 and the application of QDM v5.6 Section 5.7.3.1 (https://ecqi.healthit.gov/sites/default/files/QDM-v5.6-508.pdf#page=86) in CMS156v11. Additional questions regarding QDMv5.6 can be directed to the QDM Issue Tracker (https://oncprojectracking.healthit.gov/support/projects/QDM/summary).

In CMS156v11, a numeric value is expected for daysSupplied. There are two options for calculating days supply, as noted in QDM v5.6 Section 5.7.3.1. The second option allows days supply to be derived from other attributes (i.e., supply, dosage and frequency) when the daysSupplied attribute is absent.
(1) daysSupplied * (1+number of refills)
(2) (supply/(dosage*frequency)) * (1+number of refills)
This is represented by the following syntax in CMS156v11, for example: "let DaysSupply: Coalesce(AntiInfectives.daysSupplied, AntiInfectives.supply.value /(AntiInfectives.dosage.value * CMD.ToDaily(AntiInfectives.frequency)))*(1 + Coalesce(AntiInfectives.refills, 0))".

Author dateTime is not needed when calculating days supply, but may be used to calculate cumulative medication duration (CMD). Although there is no direct application of this calculation in CMS156v11, you may refer to function "MedicationOrderPeriod" to view the CQL expression of this calculation for "Medication, Order". This function can be found in the CQL file "CumulativeMedicationDuration-v1-0-000-QDM-5-6.cql" available at "https://ecqi.healthit.gov/sites/default/files/ecqm/measures/CMS156v11-v2.zip".

 Description   

Hi Team,

Below mentioned is the calculation for CMD from QDM-v5.6:

5.7.3.1 CMD for Medication, Order 
Calculate based on daysSupplied (number of days of medication supply per dispense) 
multiplied by (1 + number of refills) for “Medication, Order”.

● Option 1 - use daysSupplied:
CMD = daysSupplied, beginning with author dateTime * (1+ #refills)
Since daysSupplied addresses a single dispensing event, multiply by (1 + number of 
refills)

● Option 2 - when daysSupplied is absent, derive it from other existing data - supply 
(quantity of medication ordered), dosage (quantity per unit), and frequency (number of 
units to be taken per time period)
CMD = [(supply / (dosage * frequency)] beginning with author dateTime * (1+ #refills) .

Query:

As per option 1, use daysSupplied : Are we expecting a numeric value for days supplied or daysSupplied should be calculated by multiplying author dateTime * (1+ #refills)
