How to Report Medicare Fraud on Behalf of a Parent (2026)
By Chuck Brodsky, Co-Founder, MediNav — Updated July 2026 — 6 min read
Quick answer
If you spot a charge on your parent's Medicare statement for care they never received, you are looking at the most common form of Medicare fraud, and you can report it yourself. Caregivers are often the first to catch it, precisely because they are the ones reviewing the statements.
What Medicare fraud looks like
Fraud usually shows up as billing for services or equipment a parent never got, charges for the same service twice, or supplies that were never delivered. It can also involve someone using your parent's Medicare number to bill for care. The pattern to watch for on a statement is a provider, date, or service your parent does not recognize. Errors happen too, so the first step is to check whether the charge is a genuine mistake before treating it as fraud.
Gather the records first
Before reporting, collect your parent's Medicare Summary Notice, if they have Original Medicare, or the Explanation of Benefits from their Medicare Advantage or Part D plan. Circle the specific line items in question — the date of service, the provider name, and the amount. Note your parent's Medicare number and the date you noticed the problem. Having these details ready makes the report faster and more useful to investigators.
Who to call
For Original Medicare billing questions and to report suspected fraud, call 1-800-MEDICARE (1-800-633-4227). For fraud, waste, or abuse involving federal health programs, contact the HHS Office of Inspector General hotline at 1-800-HHS-TIPS (1-800-447-8477) or file a report through the OIG website. If your parent is in a Medicare Advantage or Part D plan, you can also report suspected fraud to the plan directly using the number on their card.
Get free local help from the Senior Medicare Patrol
Every state has a Senior Medicare Patrol, a program funded by the federal Administration for Community Living that helps beneficiaries and caregivers detect, prevent, and report Medicare fraud at no cost. A local counselor can help you read a confusing statement, decide whether a charge is an error or fraud, and route a report to the right place. This is often the easiest starting point for a caregiver who is not sure what they are looking at.
Protect your parent's Medicare number
Reporting is reactive; prevention matters too. Treat your parent's Medicare number like a credit card number. Be wary of unsolicited calls offering free equipment or genetic tests in exchange for the number, which is a frequent scam. Review statements regularly, because the sooner a false charge is caught, the easier it is to resolve and the less time a misused number has to accumulate charges.

Frequently asked questions
What if I am not sure whether a charge is fraud or just a billing error?
Start by calling the provider to ask about the charge — many are honest mistakes. If the provider cannot explain it, or you suspect intentional misuse, report it to 1-800-MEDICARE or the HHS OIG hotline. Your local Senior Medicare Patrol can help you tell the difference at no cost.
Do I need my parent's permission to report fraud?
You can report suspected fraud you have observed on your parent's statements. Having your parent's Medicare number and the relevant statements helps. For ongoing involvement with Medicare on your parent's behalf, consider setting up formal authorization, but reporting a suspicious charge does not require it.
What information should I have ready?
Your parent's Medicare number, the provider's name, the date of service, the amount charged, and a description of why the charge looks wrong. Pull these from the Medicare Summary Notice or the plan's Explanation of Benefits before you call so the report is complete.
Is there a cost to report fraud or get help?
No. Calling 1-800-MEDICARE and the HHS OIG hotline is free, and the Senior Medicare Patrol provides free, local assistance to beneficiaries and caregivers. You should never pay to report Medicare fraud or to get help reviewing your parent's statements.
What happens after I report?
The information goes to investigators who review billing records and patterns. You may not hear the outcome, because investigations are confidential, but your report still contributes to identifying fraud. Keep copies of the statements and a note of when and to whom you reported.
How can I prevent Medicare fraud against my parent?
Guard your parent's Medicare number, decline unsolicited offers of free equipment or tests in exchange for it, and review every Medicare statement promptly. Catching a false charge early makes it easier to resolve and limits how long a misused number can be billed against.
