Nearly 5,000 people created new accounts with Minnesota’s new online health insurance marketplace in the first week, despite a bumpy start. MNsure officials say the number is higher than anticipated, with the call center averaging 1,000 calls a day from across the state. State and federally run health insurance exchanges that are key to the Obama administration’s health care overhaul went live across most of the country last Tuesday morning. MNsure delayed its launch until that afternoon to run additional tests. Many early visitors to the MNsure website had trouble creating accounts, which was traced to a server problem, but by Friday, 97% of consumers were reportedly able to get through.
