Common questions

How do I verify a healthcare license in Illinois?
Verify with the Illinois board that issued the license. This directory lists 3 Illinois licensing lookups, including Illinois Department of Financial and Professional Regulation, Illinois Directory of Radiologic Technologists, and Illinois Nurse Aide Registry. Pick the board for the provider's profession; each entry links to the board's own verification page.
Does Illinois publish a Medicaid exclusion list?
Yes. Illinois Medicaid Exclusion List is the state list. Check it alongside the federal OIG LEIE and SAM.gov, since state exclusions are not always reflected in the federal lists.
Does Illinois require a separate controlled substance registration?
Yes. Illinois Controlled Substance Lookup verifies the state registration, which is required in addition to a federal DEA registration to prescribe controlled substances in Illinois.
Where do providers enroll in Illinois Medicaid?
Illinois Medicaid Program Advanced Cloud Technology is the state's provider enrollment portal. Medicaid enrollment is separate from commercial payer enrollment and from Medicare enrollment through PECOS.
