Mailing Problem Leads to BreachSystem Placed Wrong Addresses on Insurance Mail
In late January, the insurer discovered that a system error had caused it to inadvertently mail some member health information to incorrect addresses. The company recently converted to a new source of customer mailing address information, and the new system tracks both prior and current member addresses, according to a company statement. During the system conversion, 7,400 old customer mailing addresses were mistakenly identified as current addresses and used for a three-month period.
The mismailings included explanation of benefits forms. But they did not include Social Security numbers, dates of birth or financial information, the insurer said.
The Blues plan has notified affected members as required under the HITECH Act breach notification rule. The insurer said it fixed the mailing system problem the same day that it was discovered and has "evaluated its systems and made the appropriate changes to prevent this error from reoccurring.
