Free Health Clinics in San Antonio: Care With No Insurance (2026)

Many San Antonio residents don’t have health insurance — that’s exactly who these clinics serve. Here in San Antonio, “no insurance” doesn’t have to mean “no care.” There are free and low-cost clinics across the city where you can get checkups, dental work, prescriptions, and more — many on a sliding scale that drops to $0 if your income is low. Here’s where to go.

Key takeaways

  • Free or nearly free care: San Antonio’s Federally Qualified Health Centers charge on a sliding scale — care can be $0 if you’re low-income, no insurance required.
  • Major clinic networks: CentroMed and CommuniCare offer free/low-cost primary care, dental, behavioral health, and prescriptions.
  • Free prescriptions: Ask about sliding-scale pharmacies and manufacturer programs that make medications free.
  • Long-term fix: You may qualify for free Medicaid or low-cost CHIP — apply any time at YourTexasBenefits.com or call 2-1-1.

Federally Qualified Health Centers (FQHCs)

These clinics charge on a sliding fee scale based on your income. Ask the clinic about its sliding-fee scale when you call. They provide primary care, dental, behavioral health, and prescriptions. Major San Antonio FQHC networks include CentroMed and CommuniCare. Some, like CentroMed, advertise walk-in clinics. Hours vary — call ahead to confirm.

The long-term fix: get covered

If your income is low, you may qualify for free Medicaid — and your kids may qualify for CHIP even if you don’t. Apply at YourTexasBenefits.com or call 2-1-1, select your language, and choose Option 2 for state benefits. Open enrollment isn’t a barrier for Medicaid/CHIP: you can apply any time of year. Pregnant women should also look into WIC (healthy food + nutrition counseling) at texaswic.org/apply or 800-942-3678 — and Medicaid covers pregnancy care for qualifying moms.
