Anthem Database Breach and Potential Effect
on Health Plan Members

Update: Health insurer Anthem Blue Cross Blue Shield has announced that members (current and former) dating back to 2004 are being offered identity repair assistance and credit monitoring services via Affected members can start accessing these services prior to receiving a mailed notification from Anthem and can enroll any time during the 24-month coverage period. Learn how to sign up at or call toll free 1-877-263-7995 from 9:00 a.m. to 9:00 p.m., Monday through Friday, Eastern Time.

Health insurer Anthem Blue Cross Blue Shield Health Plan (Anthem) announced this week it was the target of a sophisticated external cyber attack. As a result, its information technology system databases containing personal information of current and former members may have been compromised. The type of information accessed includes member names, birth dates, member health ID numbers, Social Security numbers, mailing and email addresses, and employment information. Thus far, Anthem officials believe that specific medical information and credit card numbers were neither targeted nor compromised.

How does this event affect me?

The Anthem data breach may affect current and former members and dependents who have health coverage and dental coverage through the following plans currently or previously offered by the State of Wisconsin Group Health Insurance Program:

  • Anthem Blue Preferred-Southeast Network
  • Anthem Blue Preferred-Northeast Network
  • Anthem Blue Preferred-Northwest Network
  • Anthem Dental Blue
  • Standard Plan participants from 1994-2005 (Blue Cross Blue Shield administered the Standard Plan from 1994-2005)

This event does not affect members of the other health plans offered through the group health insurance program.

Anthem will contact current and former members whose information has been accessed with detailed information and instructions. In the meantime, more information is available at or by calling Anthem toll free at 1-877-263-7995.

The Department of Employee Trust Funds, administrator of the state’s group health insurance program, takes this event very seriously and is continuously enhancing security protocols already in place, and works with health plans and other outside providers to better ensure your account data is protected at all times.
