This variable indicates whether a beneficiary met the criteria for the Use of MedicationAssisted Treatment (MAT) as of the end of the calendar year.


The condition variable requires beneficiaries to satisfy both claims criteria (a minimum number/type of Medicare claims that have the proper codes and occurred within a specified time period) and coverage criteria (Medicare FFS Part A and Part B coverage during the entire specified time period).

For use of Medication-Assisted Treatment (MAT), beneficiaries must have one or more drug claim (Medicare Part B, Medicare Part D, and/or Medicaid) with an NDC (national drug code) for opioid-MAT or one or more non-drug claim (Medicare Part B or Medicaid non-drug claim) with a HCPCs code during the two year period.

 You can find more detailed information on the criteria on the CCW website:
