This letter (here) explains new ex parte review process for MAGI Medi-Cal annual reviews. Informs counties that pre-ACA Medi-Cal cases will be redetermined starting in May 2014 and provides a schedule for January 2014 -April 2014 redeterminations. At the first post-2014 counties will collect baseline information from pre-ACA Medi-Cal enrollees in order to move them into MAGI Medi-Cal by sending the Request for Tax Household Information (copy is attached to the letter). The errata to this letter, available here, states that redeterminations will not begin until June 2014.
