About Contra Costa Health Plan

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 45 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. In 2014 as part of the implementation of the Affordable Care Act, CCHP enrolled over 35,000 newly eligible individuals into Medi-Cal Managed Care and in 2015 over 25,000 more individuals enrolled into CCHP Medi-Cal Managed Care.

Contra Costa Health Plan now serves over 227,000 people in Contra Costa County and continues to be at the forefront of offering comprehensive, quality health coverage.
