A computer disk containing the names , birth dates and Social Security numbers of 2.9 million Medicaid and childrens health care recipients is missing , Georgia health officials said Tuesday . The state said the security breach was reported by Affiliated Computer Services , a private vendor with a contract to handle health care claims for the state . The CD was lost while it was being shipped from Georgia to Maryland , ACS spokesman David Shapiro said . The company has been working with the carrier , which Shapiro would not identify , for several days to find the package , he said . Shapiro said there was no indication anyone had tried to access any of the personal data . We are treating this as a missing package , he said . Officials said the information , including addresses , covered the four - year period up to June 2006 and included some people who are no longer on the rolls . The Georgia Department of Community Health said it was requiring the Dallas - based company to notify everyone affected and to offer free credit reports . The childrens health care program involved in the data loss is called PeachCare . PeachCare is the states health insurance program for low - income children . Medicaid is a health insurance program for the poorest residents . Both programs are funded with a combination of state and federal dollars . State officials notified the Centers for Medicare and Medicaid Services , the U.S. Department of Health and Human Services , the Governors Office of Consumer Affairs and the state attorney general . ;
