Medicare fraud costs taxpayers billions of dollars every year and can directly harm beneficiaries through stolen personal information, unnecessary medical procedures, and compromised benefits. Scammers target Medicare recipients because the program covers tens of millions of Americans and processes an enormous volume of claims. By understanding how fraud works and knowing what to watch for, you can protect both your health coverage and your identity.
Common Medicare Scams to Watch For
Fraudsters use a variety of tactics to exploit Medicare beneficiaries. Here are the most prevalent schemes:
Medicare Card Scams
Since Medicare cards carry your Medicare Beneficiary Identifier (MBI), scammers want this number badly. Common approaches include:
- Phone calls claiming to be from Medicare, asking you to "verify" or "update" your Medicare number. Official Medicare representatives will almost never call you unsolicited.
- Fake mailings requesting that you provide your MBI to receive a "new card" or "updated benefits."
- Door-to-door visits from individuals posing as Medicare employees who ask to see your card or collect personal details.
Remember: Medicare will never call you to ask for your Medicare number. They already have it. If someone contacts you requesting this information, it is a scam.
Durable Medical Equipment (DME) Fraud
DME fraud is one of the most widespread forms of Medicare abuse. It involves billing Medicare for medical equipment that was never delivered, not medically necessary, or far more expensive than what was actually provided. Watch for:
- Unsolicited offers for free back braces, knee braces, or other equipment — often through telemarketing calls or online ads
- Companies that ship equipment you never requested and then bill Medicare for it
- Providers who ask you to sign blank forms or paperwork you do not fully understand
If you receive medical equipment you did not order, do not ignore it. Report it immediately.
Billing Fraud
Healthcare providers or organizations may engage in billing fraud by:
- Billing for services not rendered: Charging Medicare for appointments or procedures that never happened
- Upcoding: Billing for a more expensive procedure than the one actually performed
- Unbundling: Separating services that should be billed as a package into individual charges to increase the total
- Phantom billing: Creating claims for fictitious patients or providers
You may not even realize you are a victim of billing fraud unless you carefully review your statements.
Reviewing Your Medicare Summary Notice
Your best defense against billing fraud is your Medicare Summary Notice (MSN). This document is mailed to you every three months if you have Original Medicare, and it details every service and supply billed to Medicare on your behalf.
When you receive your MSN, take the time to:
- Verify that you received every listed service. If a claim appears for a date when you did not visit a doctor or facility, that is a red flag.
- Check the provider names. Make sure you recognize every provider listed. Fraudulent claims sometimes come from providers you have never seen.
- Look at the amounts billed. If a charge seems unusually high for the service you received, investigate further.
- Compare with your own records. Keeping a simple log of your medical appointments and services — even just dates and provider names — makes it much easier to spot discrepancies.
If you have a Medicare Advantage plan, you will receive an Explanation of Benefits (EOB) from your plan instead of an MSN. Review it with the same level of attention.
How to Report Medicare Fraud
If you suspect fraud, reporting it is straightforward and important. You have several options:
- Call 1-800-MEDICARE (1-800-633-4227). This is the primary number for reporting suspected fraud. TTY users can call 1-877-486-2048. Representatives are available 24 hours a day, seven days a week.
- Contact the Office of Inspector General (OIG). You can file a complaint online through the OIG website or call 1-800-HHS-TIPS (1-800-447-8477). The OIG investigates fraud involving Medicare and other federal health programs.
- Report to your Medicare Advantage or Part D plan. If you are enrolled in a private Medicare plan, contact the plan directly. They have fraud investigation units and are required to act on credible reports.
- File with your state's Senior Medicare Patrol (SMP). SMP programs operate in every state and are staffed by trained volunteers who help beneficiaries detect and report fraud. They offer free assistance and can guide you through the reporting process.
You may also be eligible for a reward through the OIG if your report leads to the recovery of funds. The False Claims Act allows whistleblowers to receive a percentage of recovered amounts in certain cases.
Protecting Your Medicare Number
Your Medicare Beneficiary Identifier is essentially the key to your Medicare benefits. Treat it with the same care you would give your Social Security number or bank account information.
Best practices include:
- Do not share your MBI with anyone who contacts you unsolicited — whether by phone, email, text, or in person
- Keep your Medicare card in a safe place. Do not carry it in your wallet unless you are going to a medical appointment
- Shred documents that contain your MBI before discarding them
- Be cautious at health fairs and community events where vendors may ask for your Medicare number in exchange for "free" screenings or products
- Never give your Medicare number to get a gift, money, or free services. Legitimate Medicare services do not require this trade
- Monitor your credit reports periodically for signs of medical identity theft
If you believe your Medicare number has been compromised, call 1-800-MEDICARE immediately to report it. You can request a new MBI if fraud has occurred.
The Role of Senior Medicare Patrol
The Senior Medicare Patrol (SMP) program is a nationwide network funded by the federal government to help Medicare and Medicaid beneficiaries prevent, detect, and report healthcare fraud. SMP volunteers are active in every state and provide:
- Educational presentations at community centers, senior centers, and faith-based organizations
- One-on-one counseling to help you review your MSN or EOB for signs of fraud
- Assistance with reporting suspected fraud to the appropriate agencies
SMP services are completely free and confidential. To find your local SMP program, call 1-877-808-2468 or visit the SMP Resource Center online.
What Happens After You Report Fraud
Once you file a fraud report, the relevant agency will review the information and may launch an investigation. You should know that:
- Investigations can take time. Complex fraud cases may require months or years to resolve.
- You are protected from retaliation. It is illegal for any provider to retaliate against you for reporting suspected fraud.
- Your benefits are not affected. Reporting fraud does not change your Medicare coverage or eligibility in any way.
- You may be contacted for additional information. Investigators might follow up with questions, so keep records of your original complaint and any supporting documents.
Stay Vigilant
Medicare fraud thrives when beneficiaries are uninformed or inattentive. By reviewing every statement, guarding your personal information, and promptly reporting anything suspicious, you play a direct role in protecting the program — and yourself. A few minutes of attention each quarter can save you from significant headaches and help preserve Medicare for everyone who depends on it.
