Missouri state officials are notifying 1,357 Medicaid participants that some of their personal information was mailed to an incorrect address.
MO HealthNet, the state's managed care service for Medicaid clients in Mid-Missouri, 43 other counties and St. Louis City, didn't provide more detailed information about where the affected clients live.
A Monday afternoon news release said one of MO HealthNet's contractors - Infocrossing Inc. - sent the information to a wrong address because of a software programming error that since has been corrected.
The agency emphasized that no medical or financial information was released - but some clients' names, birth dates, MO HealthNet identification account number (DCN), name of the county where they live, phone number and the last four digits of their Social Security number were included in the mailings.
While officials have "no reason to believe that any identity theft or other wrongdoing has occurred as result of this incident," the release said Infocrossing will offer free credit monitoring services for two years.
There is no additional cost to the taxpayer, the release said.
The problem was discovered June 6.
Monday's release said the software programming error affected some of Mo HealthNet's correspondence sent between Oct. 16, 2011, and this past June 7.
Notifying the clients is required by federal and state privacy laws, including HIPAA, the 1996 federal Health Insurance Portability and Accountability Act.
The written notices tell the affected individuals that some personal information may have been disclosed. Clients receiving the notice can call MO HealthNet, toll-free, at 877-309-0021 with concerns and for information in identity theft protection.
