Duplicate charge

What does Duplicate charge mean on a medical bill?

A duplicate charge is the same service billed twice. It is usually process rather than intent: a corrected claim posted next to the original instead of replacing it, two departments billing the same item, one visit split across statements, or a resubmission after a denial that never got reversed. You find them by lining up date, code, and quantity across the itemized bill and the EOB, and then asking which record backs up each line.

What should I watch out for with Duplicate charge?

• The same code on the same date across two lines — ask which record supports each
• A corrected claim sitting beside the original instead of replacing it on the account
• Two statements for one visit both showing the same total — ask the biller which account is live
