Other ways to find care

How free and low-cost care works

Most clinics here charge on a sliding scale: what you pay depends on your household income and family size, and the lowest-income patients often pay nothing. Bring a photo ID, proof of income and proof of address to get the lowest fee. How sliding-scale fees work

If none of the clinics above fit your situation, two other places to try are 211 (dial 2-1-1 from any phone in the US for a referral to local social services, including health clinics) and your county health department, which often runs its own low-cost or sliding-scale clinics in addition to the ones listed here.
