Billed for Medical Care You Didn’t Receive? What to Do

Legal Guides · Updated October 2026

If your insurance statement shows a visit, test or therapy session you never received, keep the paperwork and look for a pattern. One wrong code is often a clerical error. Repeated charges for care that never happened can be a sign that a provider is billing insurers for services it never gave, often to many patients at once. Here is how to tell the difference, where to report it, and when a patient may be able to bring a case.

Billing Errors vs. Billing Fraud

Check the Explanation of Benefits (EOB) your health plan sends after each claim. A single wrong date or code is often an honest mistake. Patterns are what point to fraud:

• Visits or sessions billed on days you were not there
• Longer visits than you had, such as a 60-minute therapy session billed for a 20-minute appointment
• Tests, equipment or prescriptions you never received
• A doctor listed as your provider when you only saw an assistant, or someone you never met
• Charges that continue after you stopped going
• Other patients you know noticing the same thing

What to Do First

1. Save your statements. Keep every EOB, bill and appointment reminder. Most health plans let you download past EOBs from their website or app.
2. Write down what really happened. Note the dates you were seen, how long each visit lasted and who treated you, while you still remember.
3. Request an itemized bill if the provider has billed you directly.
4. Decide whether to contact the provider. For an obvious one-time error, a call to the billing office may be enough. If you suspect deliberate fraud, talk to a lawyer before you confront the provider.

Where to Report Suspected Billing Fraud in California

• Private health plan: call the member services number on your insurance card and ask for the fraud or special investigations unit.
• California Department of Insurance: accepts reports of suspected insurance fraud.
• Medi-Cal: report to the California Department of Health Care Services.
• Medicare: call 1-800-MEDICARE or report to the U.S. Department of Health and Human Services Office of Inspector General.

Reporting to an agency or your health plan does not make you eligible for a share of any recovery. A whistleblower lawsuit is a separate step with its own rules and deadlines.

Can a Patient Bring a Whistleblower Case?

In some cases, yes. California’s Insurance Frauds Prevention Act allows “any interested persons” to sue on behalf of the State of California over fraud against private insurers. A successful whistleblower may receive 30 to 50 percent of the recovery. If you paid the provider money because of the fraud, the law also allows the court to award up to double that amount in some cases. When the billing went to Medicare or Medi-Cal, the federal and California False Claims Acts may apply instead.

A case usually needs more than one wrong bill. It is strongest when your experience shows a practice, such as a clinic billing every patient for the same service, and when other patients or employees have seen the same thing. A lawyer can help you decide whether what you have seen is enough.

Medical Identity Theft Is Different

If the charges come from a provider you have never visited, someone may be using your insurance information. Contact your health plan right away, ask for a copy of the records billed under your name, and consider reporting identity theft at IdentityTheft.gov.

Frequently Asked Questions

Will I owe money for care I didn’t receive?

You should not. Dispute the charge in writing with both the provider and your health plan, and keep copies of everything you send.

Will reporting affect my coverage or my care?

Your health plan should not penalize you for reporting suspected fraud. If you are worried about ongoing care with the provider, talk with a lawyer before you take any steps.

Can a patient get a reward for reporting billing fraud?

Reporting to your plan or a government agency does not pay a reward. A patient who brings a successful whistleblower lawsuit under California’s Insurance Frauds Prevention Act may receive 30 to 50 percent of the recovery. No amount is guaranteed.

Is there a deadline?

Yes. An Insurance Frauds Prevention Act case generally must be filed within three years of discovering the facts, and never more than eight years after the violation. Waiting can also allow someone else to file first.

What does it cost to talk to a lawyer?

A case review is free and confidential. We handle whistleblower cases on a contingency fee basis. You pay no attorney’s fees unless there is a recovery.
