Medicare fraud occurs when someone knowingly submits false claims to the program to receive payment they are not entitled to. Patients, family members, and healthcare workers all play a role in spotting these schemes. Knowing the warning signs can help you protect your benefits, your identity, and the integrity of the program.
Common Warning Signs for Patients and Families
Review your Medicare Summary Notices (MSNs) and Explanation of Benefits (EOBs) carefully each time they arrive. Look for charges for services, equipment, or supplies you never received. Other red flags include:
- Being billed for the same service or item more than once.
- Providers who waive copays or deductibles as an incentive to get you to accept services.
- Unsolicited phone calls offering free medical equipment, genetic testing, or health screenings in exchange for your Medicare number.
- Providers who pressure you into services you do not need or that your doctor never ordered.
- Charges for durable medical equipment, such as back braces or oxygen supplies, that you never received.
- Prescriptions billed to Medicare that you never picked up or that your doctor never prescribed.
- Providers who tell you a service is "free" but then bill Medicare for it anyway.
Identity theft is a common component of Medicare fraud. If someone obtains your Medicare number, they can bill the program in your name. If you see unfamiliar providers or services on your statements, treat it as a potential sign that your information has been misused.
What Healthcare Workers Should Watch For
Healthcare employees may notice patterns that patients cannot see. These include upcoding (billing for a more expensive service than was provided), unbundling (separately billing procedures that should be billed together), and billing for services that were never performed. If you observe these practices, you may be in a position to report them.
How to Report Suspected Fraud
If you believe you are a victim, contact the HHS-OIG hotline at 1-800-HHS-TIPS (1-800-447-8477). Beneficiaries can also call 1-800-MEDICARE to report suspicious charges. Keep copies of your statements and any documentation related to the suspected fraud.
Whistleblower Options for Healthcare Workers
Workers who report fraud may have protections under federal law. The federal False Claims Act (31 U.S.C. 3729-3733) allows private individuals, known as relators, to file qui tam lawsuits on the government's behalf. These complaints are filed under seal, meaning they are not immediately made public. If the government intervenes in the case, relators generally receive 15 to 25 percent of the recovery; if the government does not intervene, the relator share is 25 to 30 percent.
Liable parties can owe up to three times the government's damages plus per-claim civil penalties that are adjusted for inflation each year. The general deadline for filing is six years from the violation, or three years from when the government knew or should have known, but no more than ten years in total.
Employees who face retaliation for reporting fraud are protected under 31 U.S.C. 3730(h). Remedies can include reinstatement and double back pay, among other relief. If you are considering reporting, you should understand these protections before taking action.
Practical Next Steps
- Keep a log of every Medicare service you receive and compare it to your statements.
- Never share your Medicare number with unknown callers or vendors.
- Report suspected fraud promptly to the hotlines above.
- If you are a healthcare worker, document what you observed and consult the qui tam process before discussing it with your employer.
Identifying fraud early protects your benefits and helps ensure Medicare remains available for those who need it. When in doubt, report what you see.
