Stanford Benefits was recently made aware of a cyberattack against Premera Blue Cross, a health insurer based in the Pacific Northwest. Premera Blue Cross is separate and independent from Blue Shield of California, which administers our EPO, PPO and HDHP medical plans. Blue Shield of California's information technology systems remain unaffected by the Premera breach.  

However, if Blue Shield of California members traveled to Washington or Alaska and received medical care through the BlueCard Program or reside in Washington or Alaska as part of the Blue Distinction Total Care Program, they may be affected by this breach.

Premera has notified those individuals who may be affected, and will be offering two years of free credit monitoring and identity theft protection services.

For questions or concerns regarding your Blue Shield EPO, PPO and HDHP plan, please contact Blue Shield member services at 800-873-3605 or visit
