About urgent care in Illinois

Illinois is served by 2,045 urgent care centers and walk-in clinics listed on UCL, spread across 508 cities. These facilities provide non-emergency, outpatient care on a walk-in basis with no appointment needed.

Most Illinois urgent care centers handle non-life-threatening illnesses and injuries for adults and children: fevers, sprains, lacerations, infections, sports physicals, X-rays, lab tests, and minor procedures. Centers in larger cities often have on-site labs and imaging, while smaller community clinics offer more limited services.

UCL listed clinics in Illinois do not replace a primary care physician or a hospital's emergency department. They fill the gap between the two: care that can't wait for a doctor's appointment but isn't life-threatening. For chest pain, difficulty breathing, severe bleeding, sudden weakness, or any potentially life-threatening symptom, call 911.
