Medicare Fraud Scam
Your Medicare number is as valuable as your Social Security number — and scammers want it just as badly. A caller claiming to be Medicare says your card is expiring, a free benefit is available, or your coverage will lapse. Hand over that number and the fraud begins immediately: phantom services billed to your account, your identity used to open medical records, and benefits you’ll never know are being drained.
What Is Medicare Fraud?
Medicare fraud encompasses both the scams targeting individual beneficiaries and the large-scale billing fraud perpetrated by unscrupulous healthcare providers. From a consumer protection perspective, the most important threat is Medicare impersonation fraud — scammers posing as Medicare representatives to steal beneficiary identification numbers that are then used for phantom billing, identity theft, and benefits fraud.
The Department of Health and Human Services estimates that Medicare fraud costs the program over $60 billion annually. A significant and growing portion involves beneficiary identity theft — where stolen Medicare numbers are used to submit false claims for expensive medical equipment, laboratory tests, home health services, and procedures that were never performed.
The transition to the Medicare Beneficiary Identifier (MBI) — replacing the Social Security number that previously appeared on Medicare cards — was a significant security improvement. However, scammers have adapted, now targeting beneficiaries for their MBI numbers directly through impersonation calls that claim the new card requires verification, activation, or reissuance.
How Medicare Scams Target Beneficiaries — Step by Step
The Medicare Impersonation Call
A caller identifies themselves as a Medicare representative and explains there is a problem with your account — your card is expiring, a new benefit requires enrollment, or suspicious activity has been detected. The caller may already know your name, address, and partial Medicare information — sourced from data broker databases — which lends the call an unsettling legitimacy. You can check what information data broker sites currently hold on you using our free tool. They then request your full Medicare number to “verify your identity” or “process the update.”
The Free Equipment and Services Lure
A common variant offers something free: a back brace, knee brace, CPAP machine, diabetic supplies, or genetic cancer screening test. You just need to provide your Medicare number so they can “bill Medicare directly at no cost to you.” The equipment either never arrives or is cheap and medically unnecessary. Medicare is billed for far more than the item’s value — sometimes thousands of dollars per claim — under your number and without your knowledge.
Phantom Billing
Once in possession of your Medicare number, name, and date of birth, fraudulent providers submit claims for services you never received — office visits, laboratory tests, surgical procedures, home health visits. These claims are processed automatically by Medicare’s payment systems and paid before any human review occurs. The fraud may continue for months, consuming your benefits and potentially creating false medical records that affect your actual care.
Medical Identity Theft
Beyond billing fraud, your Medicare number combined with other personal details enables full medical identity theft. False medical records created in your name — listing procedures performed, diagnoses made, medications prescribed — can affect your actual coverage decisions, create dangerous discrepancies in your real medical history, and take years to correct. Medical identity theft has the longest-lasting real-world consequences of any identity fraud type.
What Medicare Will Never Ask You to Do
- Medicare will never call and ask for your Medicare number to keep your coverage active, issue a new card, or verify your account — Medicare already has your number.
- Medicare will never offer free medical equipment, tests, or services in exchange for your Medicare number over the phone or at a community event booth.
- Medicare will never threaten to cancel your benefits if you do not provide information or payment immediately.
- Medicare will never ask for payment by gift card, wire transfer, or cryptocurrency for any service, fee, or obligation.
- Medicare will never call to conduct a survey that requires your Medicare number, Social Security number, or bank account details to complete.
- Medicare representatives will never ask you to keep a conversation confidential from your family or healthcare provider.
💡 Treat Your Medicare Card Like a Credit Card
Your Medicare number should be shared only with your treating physicians, approved healthcare providers, and trusted people helping manage your care. Guard it with the same diligence you give your credit card number. Review your Medicare Summary Notice every time it arrives — it lists every service billed to your account and is your primary early-warning system for unauthorized use. Any service you don’t recognize should be reported to 1-800-MEDICARE immediately.
High-Risk Medicare Scam Environments
Community health fairs and senior events
Fraudulent booths at health fairs, senior centers, and community events offer free health screenings — genetic testing, vision screenings, hearing tests, or cardiovascular assessments — and ask for your Medicare card to “process the free benefit.” Medicare only covers services ordered by your treating physician for a specific medical purpose.
Telemarketing campaigns targeting seniors
Robocall and live telemarketing campaigns targeting Medicare beneficiaries run at high volume, particularly around Medicare open enrollment periods (October 15 to December 7 each year). During open enrollment, the volume of legitimate Medicare communications creates cover for fraudulent calls using similar language and urgency.
Unsolicited home health and equipment deliveries
Some operations send unsolicited medical equipment to Medicare beneficiaries based on their demographic information, then bill Medicare as though a physician ordered it. Recipients who keep and use the equipment may not realize that accepting it validates the billing claim, making them inadvertent participants in fraud that costs Medicare thousands of dollars per item.
What To Do If Your Medicare Number Was Compromised
- Call 1-800-MEDICARE (1-800-633-4227) immediately to report that your number may have been compromised and to request a review of recent claims on your account.
- Review your most recent Medicare Summary Notices for any services you do not recognize — flag each one and report it during your call.
- Request that Medicare issue you a new Medicare Beneficiary Identifier if unauthorized claims are found — this is possible and stops the fraudulent billing going forward.
- Place a credit freeze with all three credit bureaus — Medicare fraud frequently accompanies broader identity theft using the same personal information.
- Medicare fraud can generate tens of thousands of dollars in fraudulent claims in your name — and the downstream effects on your benefits and medical records can last years. Our Identity Theft Cost Calculator can help you understand the full scope of financial exposure beyond the immediate billing fraud.
- File a report with the HHS Office of Inspector General at oig.hhs.gov or 1-800-HHS-TIPS, which investigates Medicare fraud specifically.
- Report to the FTC at identitytheft.gov if you believe full identity theft has occurred beyond the Medicare number — the site generates a personalized recovery plan.
- Alert your primary care physician to check your medical records for any services or diagnoses added without your knowledge.
Your Medicare Enrollment Status Is in Data Broker Databases
Medicare scam operations purchase consumer profiles listing age, health insurance type, and contact information from data brokers — allowing them to target beneficiaries specifically. If your Medicare number was shared with a fraudulent operation, the downstream risk extends far beyond a single billing incident: phantom claims can continue for months, and medical identity theft creates false records that affect your real care for years. An identity theft protection service monitors your accounts, SSN, and dark web exposure in real time. We’ve independently tested and compared the leading services.
