For those without health insurance everything is a lot more difficult. Fortunately, some central Illinois communities have free health clinics.
In Bloomington, BroMenn Family Health Clinic and the Community Health Clinic fill the gap for the uninsured and underinsured.
In Peoria, Heartland Community Health Clinic provides healthcare for people without insurance.
In Champaign, there was a recent front page article in the News Gazette highlighting the Champaign County Christian Health Center. A group of local churches and businesses have put the clinic together for those without insurance.
