San Mateo County ACE Program

Where Can I Get Care?

San Mateo County is the designated service area for the ACE Program. Service area means the geographic area served by the program. The ACE program will cover the costs of your medical care received only at contracted clinics and at San Mateo Medical Center (SMMC). If you need services from a medical professional that is not contracted with an ACE clinic or SMMC, you need to get a prior authorization from HPSM before receiving services.
