Last October, once the site went live, many complained about the website's flaws. One major issue was that the software could not accurately determine how much consumers would pay for coverage, FierceHealthPayer previously reported.

And while officials blamed the problems on the site's higher-than-expected usage, the Obama administration neglected these "back-burner" issues and focused their attention on fixing the part of the site consumers would use to enroll in coverage.
