Frequently Asked Questions

Can I go to a clinic in San Marcos without insurance?

Yes. Every clinic on this page is a federally funded community health center, so it must treat you whether or not you have insurance. You will be charged on a sliding-fee scale based on your income and family size, and no one is turned away for being unable to pay.

How much does a visit cost with no insurance?

It depends on your income. Community health centers use a sliding-fee discount scale set by federal rules. If your income is at or below the federal poverty level, you pay only a small nominal fee. As income rises, the discount steps down. Bring proof of income and household size to set your rate.

What services do clinics in San Marcos offer?

Most community health centers offer primary medical care, and many also provide dental, mental-health, substance-use, and pharmacy services. Services vary by site, so call the clinic to confirm what it offers before you go.

Do I need to be a US citizen to be seen?

No. Community health centers serve all patients regardless of immigration status. You do not need to be a citizen or have a Social Security number to receive care.
