MNsure should repay more than $1.2 million in grant funds, federal auditors say, including money spent on marketing work that wasn't properly authorized until after the job was completed.
Auditors from the Office of Inspector General at the U.S. Department of Health and Human Services (HHS) outlined the recommendations in a report issued Monday.
The report also flagged certain costs that MNsure allocated to federal grants, which auditors said should have been charged to state public health insurance programs.
MNsure, however, said it did not accept the recommendations. The marketing work, for example, was an allowable grant expenditure that was requested, received and utilized by MNsure, despite problems with the timing of the contract amendment.
"After reviewing the [MNsure] comments, we maintain that our findings and recommendations are valid," auditors wrote.
Officials with the federal Centers for Medicare and Medicaid Services (CMS) ultimately will decide whether repayment is warranted.
The HHS Office of Inspector General has completed audits at five other state health exchanges thus far, and raised questions about spending in four of them. An audit released this month, for example, questioned about $150 million in cost allocations by the health insurance exchange for the state of New York.
Minnesota launched the MNsure exchange to implement the federal Affordable Care Act, which called for state-level websites where people could sign up for health plans. In Minnesota, state officials opted to create an exchange that would serve the private health insurance market where individuals buy coverage, as well as people who qualify for the Medicaid and MinnesotaCare public health insurance programs.
