The Wisconsin State Journal reports that the personal information of 41,437 Unity Health Insurance customers may have been exposed when a portable hard drive was lost (h/t PHIprivacy.net).

Notification letters were sent to those affected on January 29, 2014.

The hard drive contained each customer's Unity member number, birthdate, city of residence, medications and service dates. No contact information, financial information or Social Security numbers were contained on the drive.

Unity Health says the hard drive was reported missing from the University of Wisconsin-Madison School of Pharmacy on December 12, 2013. "The School of Pharmacy had this information as part of a benefits program evaluation," Unity Health said in a statement.

"We have no reason to believe the hard drive was stolen to gain access to member information or that this information has been accessed or misused in any way," the company added. "Both Unity and the University of Wisconsin-Madison School of Pharmacy are undertaking comprehensive reviews of this breach of policy and are instituting information and re-education initiative to ensure that all employees protect member information at all times."

All affected customers are being offered one free year of identity protection services from ID Experts.
