Each year, our fraud hotline receives thousands of calls reporting possible health care fraud, waste and abuse. We encourage you to report potential cases. Your reports to us are confidential, and you may remain anonymous.
To report potential fraud, waste or abuse: File a report online or call our fraud hotline at 877-272-9741 to create a report. Statements can also be mailed to:
Blue Cross and Blue Shield of Illinois
Special Investigations Department
300 E. Randolph St., 35th Floor
Chicago, Illinois 60601
What we’ll do: Our Special Investigations Department actively reviews every call to determine if the call provides sufficient information to investigate suspected fraud and abuse.
If there is a question of fraud, we may conduct preliminary interviews and field audits to determine if fraud was intentionally committed. If the SID concludes that there was no act of fraud, the case may be referred to the appropriate business area, which may offer guidance to resolve the issue.
