Updated 2021 Medicare Advantage (Part C) Encounter Data Now Available

CMS is pleased to announce the availability of updated 2021 Medicare Advantage (Part C) Encounter data. In June 2023, CMS released a “Preliminary” version of the 2021 Medicare Advantage (MA) Encounter RIFs to give researchers earlier access to Encounter data for that service year. The Preliminary 2021 RIF data was not fully mature because Medicare Advantage Organizations (MAOs) were still submitting encounter records for that service year to CMS.
