Medical fraud and identity protection

Last reviewed August 2026

Short answer: If you think someone used your insurance or Medicare number, report it free to 1-800-MEDICARE or IdentityTheft.gov, request an accounting of disclosures from every provider on the bill, and ask in writing for the incorrect entries to be amended. None of these steps costs money.

Key takeaways

  • Your Explanation of Benefits is the earliest warning sign — read every one, even when you owe nothing.
  • Medical identity theft can put another person's diagnoses, allergies and blood type into your chart, which is a clinical risk as well as a financial one.
  • Reporting is free through IdentityTheft.gov, 1-800-MEDICARE and your state insurance department.
  • You have a legal right under HIPAA to see your records and to request an amendment when they are wrong.

How medical identity theft usually shows up

Most people find out through paperwork rather than a phone call. A claim appears for a visit you never made, a provider you have never heard of starts sending statements, or a collections letter arrives for treatment in a city you have never been to.

Other signals are quieter: your insurer says you have reached a benefit limit you never used, or a new medication or condition appears in a patient portal you did not authorise.

  • An Explanation of Benefits listing care you did not receive
  • Bills or collections notices from unfamiliar providers
  • Being told a benefit is exhausted when you have barely used it
  • Records showing a diagnosis, allergy or blood type that is not yours
  • A denial for a claim because your records show the procedure was already done

The free reporting routes

Every route below is free. Never pay a company that offers to 'clear' medical fraud for a fee — the official channels do the same work at no cost.

  • IdentityTheft.gov — the FTC's official recovery service, which builds a personal recovery plan and the letters you need
  • 1-800-MEDICARE — for anything involving a Medicare number, open 24 hours
  • Your insurer's fraud line, printed on the back of your member card
  • Your state insurance department, for a carrier that will not act
  • A police report, which some providers require before removing fraudulent charges

Cleaning up the record afterwards

Correcting a contaminated chart takes persistence because each provider holds its own copy. Ask every provider named on the fraudulent claims for an accounting of disclosures, then send a written amendment request for each incorrect entry.

Keep a dated log of every call and letter. If a provider refuses to amend, they must record your statement of disagreement in the file, and you can escalate to the HHS Office for Civil Rights.

Frequently asked

Does reporting medical identity theft cost anything?

No. IdentityTheft.gov, 1-800-MEDICARE, your insurer's fraud line and your state insurance department are all free. Any service charging a fee to report or resolve it is selling you something you can do yourself at no cost.

Can I be made to pay for treatment someone else received on my policy?

You should not be. Dispute the charge in writing with the provider and the insurer, cite the fraud report, and ask the provider to recall the account from collections while it is investigated.

How do I get incorrect information removed from my medical records?

HIPAA gives you the right to inspect your records and to request an amendment. Submit the request in writing to each provider holding the record. If they refuse, they must file your statement of disagreement alongside it.

What if the fraud involved my Medicare number?

Call 1-800-MEDICARE first. Medicare can flag the number, investigate the claims, and in some cases issue a new number. Your state SHIP office can also help you review the claim history for free.
