      Medication duration should be calculated by using metadata included in the data element, not Start and End dates of the medication. Unfortunately, at the time of the test bundle release that you are using (it looks like Cypress 2.4.0), the application used to create test data did not support entry of prescription and fulfillment metadata. As a result, the “391 days” value was force entered.

      Subsequent test bundles include refined the Start and Stop Dates of the data element (for reference only), along with the required metadata to calculate CMD. Cypress 2.6.0 is the most recent version. You will find all required data to calculate CMD in this bundle.

      Additional information on CMD calculation is available in QDM 4.1.2 at:

    • CMS179v1/NQFna
    • Currently unable to calculate medication duration for active meds with no defined end dates (since med is active)

      How are we to calculate medication duration for active meds with no end dates?

      EX: CMS179v1

      Cypress test data contains a patient with the following meds:

      Warfarin (1)
      start: May 10, 2011
      end: UNK
      Warfarin (2)
      start: March 1, 2012
      end: UNK

      Warfarin Total Duration: 391 days

      Questions:
      —
      1) What reference end date is used to handle individual medication duration when the medication is active with no defined end date?

      • start of reporting period?
      • end of reporting period?
      • date of record import?

      2) How was the "391 days" summary duration produced by Cypress calculated?

      We've referred to the eCQM logic doc and JIRA, but have not been able to identify appropriate guidance. Any direction on where this is documented or how we should calculate this duration would be very much appreciated.

      Thank you
