Multiple Minnesota news outlets broke this story on Friday -- the Star Tribute, MinnPost.com, Pioneer Press, etc. -- and none mentioned any letter to Maximus, a Reston, Va.-based firm that is working on MNsure under a federal grant. It is clear that IBM Curam functionality was part of the problem. The StarTribute reported that in late November, state and county officials were forced to double-check up to 40,000 applications to determine if people were incorrectly denied premium subsidies or coverage on public programs. About 1,000 consumers were ultimately notified that they were denied tax credits they should have gotten. Curam software determines eligibility for coverage, subsidies, tax credits, etc.
