About Us


Often called the "best kept secret of Contra Costa County", Contra Costa Health Plan (CCHP) has been serving the health needs for people in the County for 40 years. CCHP was the first federally qualified, state licensed, county sponsored HMO in the United States. In 1973, we became the first county sponsored health plan in California to offer Medi-cal Managed Care coverage and in 1976, we became the first county run HMO to serve Medicare beneficiaries. In the 1980's, we expanded our programs to reach out to county employees, businesses, individuals and families.
