WHO WE ARE: Partnership HealthPlan of California is a nonprofit, community-based, public health care organization that contracts with the State to administer Medi-Cal benefits through local care providers to ensure access to comprehensive cost-effective health care. Partnership provides quality health care to over 900,000 people in 24 Northern California counties:

Butte* Colusa* Del Norte* Glenn* Humboldt* Lake*
Lassen* Marin* Mendocino* Modoc* Napa* Nevada*
Placer* Plumas* Shasta* Sierra* Siskiyou* Solano* 
Sonoma* Sutter* Tehama* Trinity* Yolo*

In addition to all Medi-Cal benefits, Partnership provides enhanced services including eyeglasses and mental health care. We have a dedicated Member Services team and a
24-hour Advice Nurse phone line, as well as Care Coordination services for complex cases.

Partnership is governed by a Board of Commissioners, comprised of locally elected officials, provider representatives, and patient advocates who meet on a monthly basis to set policy and strategic priorities for the health plan. 

WHO WE SERVE: Partnership provides health care to some of California's most vulnerable populations, which include:
low-income residents in rural counties; children; those with disabilities; and the elderly.

OUR HISTORY: Partnership was established to address the use of Solano County emergency rooms as the primary source of care for local Medi-Cal recipients. Partnership began serving Solano County as a County Organized Health System (a.k.a.
a public plan) in 1994. While Partnership has consistently grown over time, a series of significant expansions occurred between 2009 and 2013, with another in 2024.
