Quick answer
If your provider billed you twice for the same service, check whether the same CPT code and date of service appear on two different bills or two lines on the same bill. Contact the billing department to remove the duplicate.
How Duplicate Billing Happens
Duplicate billing can occur when the provider submits the same claim twice, the same service appears on two bills, or the billing system generates two statements for the same visit.
How to Identify It
Compare your bills and EOBs. Look for the same CPT code and date of service appearing on more than one document. Check whether the insurance paid for the same service twice.
Dispute the Duplicate
Contact the provider billing department with both bills and your EOB. Point out the duplicate charge and request that one be removed.
Frequently asked questions
Is duplicate billing fraud?
Not always. It is often an unintentional error. However, knowingly billing the same service twice may constitute fraud.
What if I already paid the duplicate?
Contact the provider and request a refund for the overpayment. If they refuse, file a complaint with your state insurance commissioner.
