How to Dispute a Medical Billing Error

Medical billing errors are surprisingly common. Studies estimate that a significant percentage of medical bills contain errors. Here's how to identify and dispute them.

Common billing errors

  • Duplicate charges: The same service billed twice
  • Services not received: Charges for tests or procedures you didn't have
  • Incorrect coding: Wrong billing codes that result in higher charges
  • Upcoding: A more expensive service code than what was actually performed
  • Cancelled services: Charges for services that were cancelled or rescheduled
Tip: Always request an itemized bill. You can't dispute what you can't see.

Steps to dispute

  • Request an itemized bill from the provider
  • Review each line item against your records
  • Identify specific charges that are wrong
  • Write a dispute letter referencing each incorrect charge
  • Mail certified with return receipt
