Dental insurance and access for Medi-Cal members in San Mateo County


NEW CHANGES as of 1/1/24: Kaiser Foundation Health Plan Medi-Cal transition

The California Department of Health Care Services (DHCS) has entered into an agreement with Kaiser Permanente to provide Medi-Cal coverage and care across much of the state under a single, direct contract starting January 1, 2024.

Effective January 1, 2024, some Medi-Cal members in San Mateo County will switch from Health Plan of San Mateo (HPSM) to Kaiser Foundation Health Plan (Kaiser). Members who stay with HPSM will continue to receive dental services through HPSM. 

Members who switch to Kaiser will receive dental services through the Medi-Cal Dental Fee-for-Service (FFS) program, also known as Smile, California.

If your current dentist is accepting new Medi-Cal Dental FFS members, you can stay with your current dentist. If not, you will need to find a dentist accepting Medi-Cal Dental FFS.
