A MNsure employee accidentally sent an e-mail file to an Apple Valley insurance broker's office on Thursday that contained Social Security numbers, names, business addresses and other identifying information on more than 2,400 insurance agents.
An official at MNsure, the state's new online health insurance exchange, acknowledged it had mishandled private data. A MNsure security manager called the broker, Jim Koester, and walked him and his assistant through a process of deleting the file from their computer hard drives.
Koester said he willingly complied, but was unnerved.
"The more I thought about it, the more troubled I was," he said. "What if this had fallen into the wrong hands? It's scary. If this is happening now, how can clients of MNsure be confident their data is safe?"
While MNsure officials said the mistake was quickly resolved and was the first security breach, the incident highlights concerns of those who have hounded the state for years about privacy issues surrounding the online-based health insurance exchanges.
The new marketplaces are a key vehicle for implementing the federal health law, often called Obamacare. Small-business owners as well as individuals younger than 65 are expected to begin using the health exchanges Oct. 1 to comparison-shop among various health insurance options.
Users of the exchange will need to provide sensitive information, including Social Security numbers, that will be sent to a federal hub to verify such things as citizenship and household income. This information will determine whether consumers using MNsure qualify for public health programs or tax credits that will lower the cost of premiums.
All states and the federal government, which also is setting up exchanges for some states, are scurrying to get the complex system running in less than three weeks.
