Report to Blue Cross Blue Shield
Last updated September 19, 2026
The short answer
Report health care fraud to your local BCBS company or the national hotline
Blue Cross Blue Shield is a group of local companies rather than one organisation, so reporting starts with your own. The number on the back of your member card reaches the right one.
What they handle
- Providers billing for care you did not receive
- Medicare enrolment fraud
- Calls asking for your member or Medicare number
- Equipment or tests you never ordered
How to file a report
- 1
Call the number on your member ID card
BCBS asks members who suspect, experience or witness health care or Medicare fraud to report it to their local BCBS company that way.
- 2
Or use the national hotline
If you are not a BCBS member, the report fraud hotline is 1-877-327-2583, which spells 1-877-327-BLUE.
- 3
Federal employees have their own line
Federal employees and retirees report potential health care fraud on 1-800-337-8440.
- 4
Check your statements first
The evidence is usually on the explanation of benefits. Dates, providers and services you cannot account for are what makes the report usable.
What you'll need
- Your member ID number
- The dates and services in question
- The provider name and claim number
What to expect
BCBS companies work with state and federal agencies on investigations. Individual cases feed a wider pattern rather than producing an immediate answer.
