Questioning a bill

Use a structured process when a healthcare bill does not match expectations, an EOB, or the services received.

Start with facts

Do not begin by assuming the bill is wrong. Identify exactly what differs and which organization controls that part of the process.

Common issues to investigate

  • Insurance was not billed
  • Wrong insurance information
  • Claim still pending
  • Out-of-network processing
  • Duplicate charge
  • Payment not posted
  • Service/date/provider mismatch
  • Authorization issue
  • Coding or claim correction needed
  • Estimate excluded a separate biller

Who to contact

Provider billing office

Charges, itemized statements, payments, coding review requests, and payment arrangements.

Insurance plan

Claim processing, benefits, network status, denial reasons, and appeal instructions.

Care team office

Clinical documentation or authorization coordination when relevant.

Other biller

Independent lab, imaging, anesthesia, pathology, or other separately billing organization.
