What if I have a problem with my doctor or clinic?

If you have a problem, talk to the doctor or clinic and try to work things out. If that doesn't help, you may want to change doctors.

  1. If you are in a managed care health plan, call the plan. The number is on your health plan card.

  2. If you are not in a managed care health plan, call Illinois Health Connect at 1-877-912-1999 (TTY: 1-866-565-8577). The call is free. You can also contact Illinois Health Connect.

What if I have a complaint about my managed care health plan?
