Fraud Costs Top $85 Billion a Year

Report Suspected Fraud: 1-800-336-4522 (or 410-998-5480)

Health insurance fraud has many forms, but collectively it is costing upwards of $85 billion a year, according to the US General Accounting Office. The most common types of fraud include:

Billing for services that were offered for "free"
Billing for services that weren't provided
"Upcoding" - charging for a more complex or expensive service than was actually provided
Billing for a covered service when the service actually provided wasn't covered
Billing for services provided to their own family members
Using a member ID card that doesn't belong to them
Not removing someone from their policy when they're no longer eligible (for example, former spouses or children who are no longer dependents)
Adding someone to their policy that isn't eligible (for example, grandchildren or overage dependents)
Doctor shopping - visiting several doctors to obtain multiple prescriptions (often for controlled substances)

As CareFirst members and providers, please help us fight fraud by letting us know when you encounter the following:

  • An Explanation of Benefits (EOB) showing services that you did not receive or that shows providers or dates of service that are not correct
  • Someone using a member ID card that is not theirs
  • A member adding someone to his or her policy that is not eligible or not removing former spouses or children who are no longer dependent from a policy
  • Billing for services that were not provided
  • Billing for services that are more complex that the service that was performed
