San Francisco Health Service System (SFHSS)
is offering a new HMO health plan for 2018

It’s the Blue Shield Trio HMO Plan, which is effective January 1, 2018. You will receive a letter from Blue Shield of California informing you whether you and your family are currently seeing Trio PCPs. In addition to Access+ HMO, Blue Shield will offer SFHSS non-Medicare members a new choice: Trio HMO. Trio HMO has the same benefits and plan design as Access+, and access to many of the same hospitals and physicians, but with lower contributions.

The goal of the Trio HMO plan is to provide coordinated care so that all aspects of your healthcare needs are being met at the right time, in the right place, by the right medical professionals.Current Blue Shield members whose primary care doctors are Trio HMO doctors will be automatically enrolled in the Trio HMO plan, which is the lowest cost plan, unless you complete an SFHSS Open Enrollment form electing another plan.
