The official website for Illinois’ health insurance marketplace has had 1 million unique visitors.  Get Covered Illinois made the announcement on Tuesday, calling it a major milestone. T he website launched on October 1, 2014.  Officials say that since then more than 439,000 visitors have used the screening tool that directs users to either the federal or state applications for Medicaid, nutrition and income assistance.  More than 88,000 Illinoisans signed up for private health insurance during the first four months of the nation’s new insurance marketplace system.  That number nearly matches the federal government’s goal of 88,660 Illinoisans by the end of January.  Early on, technical problems with the HealthCare.gov website kept many people from signing up.
