Blue Shield of California

For nearly 70 years, Blue Shield of California has distinguished itself with innovations that have changed the face of health care and made them a prominent force in the California healthcare market.


Throughout their history, Blue Shield has laid claim to several notable ‘firsts’ in the industry: in 1943, they offered the first health plan in the nation with coverage for pre-existing conditions under group programs; in 1950, they introduced the first catastrophic coverage in the nation; in 1984, they became the first health plan in California to offer online benefits and enrollment information; and in 2000, they introduced the state’s first cross border HMO, Access Baja.


Their tradition of innovation continues in the 21st Century as they became the first health plan to propose statewide universal coverage.
