State IT officials are attempting fixes this weekend to two MNsure glitches that have emerged during the current open enrollment period.
Over the past 10 days, three MNsure users have told the Star Tribune about a problem when health insurance applicants are asked how many years they will permit the exchange to automatically verify federal tax information.
Users who respond by selecting "zero" subsequently find they don't have a federal tax credit to discount the coverage costs.
The Star Tribune reported the other problem earlier this month as MNsure users complained they lost partial applications, and had to start the process all over, when they hit the "save and exit" button on the health exchange website.
The partial application problem affected about 600 people, MNsure officials estimated earlier this month. On Friday, they didn't put a number on how many people are running into the tax credit problem.
"These are the only two 'glitches' we've seen so far this year, and they are impacting a small minority of enrollees," wrote MNsure spokesman Shane Delaney in a Friday e-mail. "We are improving from previous years."
Minnesota launched the MNsure health insurance exchange in 2013 to implement the federal Affordable Care Act, which requires almost all Americans to have coverage or pay a tax penalty.
After its debut with serious website problems and an overwhelmed call center, MNsure has fallen short of enrollment goals despite technical improvements.
