Occupational health services, including workers' comp exams and drug screening, are available at several locations given Martinez's industrial workforce along the Carquinez Strait.

Does urgent care in Martinez accept Medi-Cal?

Yes — most urgent care clinics in the Martinez area accept Medi-Cal, California's Medicaid program. Medi-Cal covers approximately 14 million Californians statewide, and Contra Costa County has significant enrollment, particularly among families and low-income working adults.¹ Contra Costa Health Services, the county's public health system, operates clinics in Martinez that accept Medi-Cal for both primary and urgent care. Private urgent care centers in the area that participate in Medi-Cal managed care plans — including Anthem Blue Cross, Health Net, and Molina Healthcare — are also options. Always confirm your specific managed care plan is accepted before your visit, as network participation varies by location.³

How does Martinez urgent care relate to San Francisco?

Martinez is Contra Costa County's county seat, connected to San Francisco by BART and Interstate 680 but functionally a separate healthcare market. The drive to San Francisco runs 45–60 minutes under normal conditions, making local urgent care the practical choice for the city's approximately 38,000 residents.⁴ The county's care infrastructure — anchored by Contra Costa Regional Medical Center (the county hospital, located in Martinez) and John Muir Health's Concord and Walnut Creek campuses — serves the Central and East Bay corridor rather than routing patients westward. Urgent care clinics in Martinez fill the gap between primary care and the CCRMC emergency department, which serves the county's uninsured and Medi-Cal populations as a safety-net facility.
