Red Flags for Medicare Fraud: How to Spot, Avoid, and Report It

Medicare fraud drains benefits, inflates costs, and can expose you to Medicare identity theft. This guide highlights practical red flags for Medicare fraud and shows you how to spot, avoid, and report suspicious activity using your Medicare Summary Notices and Explanation of Benefits.

Identifying Unsolicited Contact Requests

Be skeptical of anyone who contacts you out of the blue about Medicare—by phone, text, email, social media, or door-to-door. Legitimate plans and providers do not cold-call to demand your Medicare number, request bank details, or pressure you to “verify” coverage.

Red flags

• High-pressure sales tactics pushing you to act “today only” or threatening loss of benefits.
• Offers of gift cards, cash, or “rebates” in exchange for your Medicare number.
• Requests to confirm sensitive data (MBI, Social Security number, banking) after initiating contact with you.
• Unsolicited pitches for genetic tests, COVID kits, or home health services you never asked for.

How to respond

• Decline politely, hang up, and never share your Medicare number with unknown callers.
• If a message claims to be your plan, call the member services number on your card to verify.
• Document the caller’s name, number, date, and what they asked for in case you need to report it.

Recognizing False Offers of Free Medical Equipment

Fraudulent medical equipment claims often start with “no-cost” braces, orthotics, or diabetic supplies. Scammers may say a doctor already approved it, or that you “only pay shipping.” If you did not request or medically need the device, it’s a likely scheme.

Red flags

• Claims that “Medicare covers everyone” without an exam or prescription.
• Requests to sign blank forms or accept equipment you did not ask for.
• Suppliers you’ve never heard of sending boxes to your home or your pharmacy.

How to respond

• Refuse delivery you did not order and keep the packing slip for your records.
• Contact your doctor to confirm whether any order was placed.
• Watch your Medicare Summary Notices (Original Medicare) or plan Explanation of Benefits for fraudulent medical equipment claims.

Detecting Billing for Services Not Received

Unauthorized billing appears as charges for visits, tests, or procedures you never had. Compare your personal calendar and receipts with each Medicare Summary Notice or Explanation of Benefits to catch discrepancies early.

Red flags

• Appointment dates when you were out of town, hospitalized elsewhere, or never saw that provider.
• Duplicate claims for the same day or service, or higher-level “upcoded” visits you didn’t receive.
• Suspicious telehealth visits, lab panels, or genetic tests you never discussed with your doctor.

How to respond

• Keep a health care journal noting every visit, test, and prescription.
• Request an itemized bill and ask the provider to correct errors promptly.
• If the charge remains, escalate to your plan or Medicare and report as potential unauthorized billing.

Understanding Denial of Coverage Indicators

Not every denial signals fraud—some involve prior authorization or coding errors. Still, specific denial patterns can reveal abusive billing or stolen identities.

Red flags

• Denials for services you never had (e.g., “frequency limit reached” when you didn’t get earlier services).
• Conflicts like “patient deceased” or “not an eligible beneficiary” when your status is current.
• Repeated requests for prior authorization for equipment or services you never pursued.

How to respond

• Ask for the provider’s clinical rationale and an itemized statement.
• If you did receive the service, follow the plan’s appeal steps; if you did not, report suspected fraud.
• Cross-check the denial with your Explanation of Benefits or Medicare Summary Notices for consistency.

Reviewing Conflicting Medical Records

Medical records accuracy matters. Conflicting diagnoses, unexplained procedures, or unknown providers in your chart may indicate errors—or Medicare identity theft.

Red flags

• New diagnoses, prescriptions, or referrals you never discussed.
• Entries for emergency visits, home health episodes, or equipment you did not receive.
• Mismatched demographic data or providers you do not recognize.

How to respond

• Request copies of your records (beyond visit summaries) and review them line by line.
• Submit a written amendment request to correct inaccuracies and keep copies.
• Use patient portals to monitor updates and compare them with your EOBs and MSNs.

Guarding Your Medicare Information

Protect your Medicare number like a credit card. Most fraud begins with data exposure, social engineering, or convenience shortcuts.

• Share your Medicare number only with trusted providers and your plan; never on unsolicited calls or messages.
• Carry your card only when needed; store photos and documents in secure, encrypted locations.
• Enable account security features (e.g., two-factor authentication) on insurer and provider portals.
• Shred labels on prescription bottles and mail that show your Medicare number.
• If you suspect Medicare identity theft, request a new Medicare number and tighten account authorizations.

Reporting Suspicious Medicare Activity

Timely reporting can prevent further losses and help recover payments. Before you call or file a report, gather facts to speed up the review.

What to gather

• Dates of service, provider names, claim numbers, and amounts from your Medicare Summary Notices or Explanation of Benefits.
• Itemized bills, delivery slips for equipment, and any call logs or messages.
• Your notes on what you actually received and where.

Where to start

• Contact the billing office or supplier to request correction and an updated statement.
• Notify your health plan’s member services or the Medicare help line to flag unauthorized billing.
• Report suspected fraud or Medicare identity theft to appropriate hotlines and your state’s Senior Medicare Patrol (SMP).

After you report

• Record confirmation numbers, names, and dates for every call or submission.
• Monitor subsequent Medicare Summary Notices and EOBs to verify that improper claims are reversed.
• Ask whether a new Medicare number is recommended and whether additional monitoring is needed.

Conclusion

Spotting red flags for Medicare fraud starts with vigilance: question unsolicited contacts, decline “free” equipment, match every claim on your Explanation of Benefits and Medicare Summary Notices, and correct inaccurate records. Guard your Medicare number and report suspicious activity quickly to stop losses and protect your benefits.
