Frequently Asked Questions
Can I go to a clinic in O Fallon 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 O Fallon 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.
