Dental Providers first need to verify customers through the MEDI site to find out the eligibility status of the customer.

Customers can either be enrolled as a Medicaid fee for service customer or enrolled in a Managed Care Plan.

Dental Providers can use the MCO Subcontractor List for all Managed Care Plan questions.

HFS recognizes the importance of providers having an outlet for reporting issues they may be having with an Illinois Medicaid Managed Care Health Plan (MCO).  All providers are required to submit unresolved disputes with an MCO to HFS via the secure, web-based Provider Resolution portal at Managed Care Provider Resolution Portal.
