CalOptima Health is a county organised health system founded in 1993 by the Orange County Board of Supervisors. It operates as an independent entity governed by a Board of Directors comprising members, providers, business leaders and local government representatives. The organisation serves as the single largest health insurer in Orange County, California, providing coverage to nearly one in three county residents through three programmes: Medi-Cal, OneCare and PACE (Program of All-Inclusive Care for the Elderly).
With approximately 1,600 employees, CalOptima Health functions as a mission-driven community-based organisation focused on health equity and access to care. The organisation provides services in members' preferred languages and maintains a collaborative approach with healthcare providers and community partners. It operates as a prudent steward of public funds, with approximately 95 cents of every dollar directed to medical care.
CalOptima Health's three-programme structure addresses diverse population needs: Medi-Cal serves low-income residents, OneCare provides coverage for working-age adults and families, and PACE delivers comprehensive long-term services and supports for elderly members. The organisation's governance model reflects its public mission whilst enabling independent operational decision-making serving Orange County's diverse communities.
