How to report Medicare or Medicaid fraud in Illinois
Where to report suspected Medicare or Medicaid fraud in Illinois, what to gather first, and what happens after you file.
Illinois Attorney General, Medicaid Fraud Control Unit
Deadline
There's no deadline to report suspected fraud to the MFCU. Illinois's own False Claims Act rewards whoever files first; once someone else files suit on the same facts, you're locked out regardless of how strong your evidence is, so act on solid information promptly.
Illinois's Attorney General took over Medicaid fraud investigations statewide in October 2023, and its MFCU takes tips through an online portal or the toll-free Medicaid/Welfare Fraud Hotline, plus email at investigationsmfcu@ilag.gov; either way you'll need to describe the provider and the suspected fraud so an investigator can follow up. The tip line pays nothing by itself. Illinois's own False Claims Act, 740 ILCS 175, lets a relator who files a qui tam suit collect 15% to 25% of an intervened recovery or 25% to 30% if the state declines to join.
Gather this first
- The provider's name and what type of Medicaid fraud you suspect
- Details on what happened and when
- Any documentation, billing records, or other evidence you have
- Your contact information, so an MFCU investigator can follow up
Submit a Medicaid Fraud Unit tip or call 866-748-2297
A reward may apply through the qui tam False Claims Act program.

After you report
- Your report is logged and an investigator reviews it. They may contact you for more detail or reach out to the provider or facility directly.
- Reporting here does not pay you on its own, but the same facts filed as a qui tam suit can pay a share of what the government recovers.
- You can usually ask to stay anonymous, and you do not need a lawyer to file the report itself.
