After receiving your Phase 2 compliance notification, you may submit a request through ResDAC to obtain Medicare data. Please include "QE Request" in the subject line of the email.

The Preliminary 2019 RIF data was not fully mature because Medicare Advantage Organizations (MAOs) were still submitting encounter records for that service year to CMS.
