Assigned in Preliminary/Prospective Assignment Period

SAS Name

0/1 flag; =1 if beneficiary was assigned in the initial performance year assignment run (Prospective Assignment or Preliminary Prospective Assignment with Retrospective Reconciliation). Note that for Prospective Assignment  ACOs the prospectively assigned beneficiaries are the same for all periods with the exception of beneficiaries that have met exclusion criteria for one or more reasons during the performance year. As a result, the number of assigned beneficiaries for Prospective Assignment ACOs will be smaller for each consecutive assignment period.
