To apply for Medicaid, Illinois residents can visit the Application for Benefits Eligibility (ABE) website to start the health care coverage application. Or, call Cook County Health Application Assistance Call Center at 312-864-8200 / 855-444-1661 (toll-free) / 711 (TDD/TTY), option 1.
Once you’re approved and enrolled in Medicaid, you may be able to choose CountyCare as your health plan. Illinois Client Enrollment Services will send you an enrollment packet that explains your choices and how to select your health plan.
Medicaid is a state and federal program that pays for your health care. Services funded through Medicaid include doctors’ visits, hospital care, vision, dental and prescription coverage.
To qualify for HealthChoice Illinois, the statewide Medicaid managed care program, you can apply any time and you must:
Once a year on your anniversary date, Medicaid members can change health plans during a specific time called “open enrollment.” You will receive a letter in the mail from the State of Illinois letting you know how to select your health plan. If you’re already a CountyCare member and want to stay a member, you don’t have to do anything. You will be automatically re-enrolled in CountyCare.
You will have at least 60 days from when you receive your letter to choose your plan. Once you pick your plan, you will not be able to change it for one year. Remember, if you’re already a CountyCare member and want to stay a member, you don’t have to do anything.
If you are a current CountyCare member or thinking about becoming a CountyCare member, your health is our top priority. Our members have access to a wide range of health services and expert care at more than 6,600 primary care providers, 26,000 specialists and 70 hospitals throughout Cook County.
Choosing CountyCare is choosing a plan that understands.
