Medicare fraud costs the program billions of dollars a year, and much of it starts with something small: a phone call, a postcard, a knock at the door, or a request for a Medicare number. The people behind these schemes rely on the fact that Medicare’s rules are complicated and that most beneficiaries want to be polite and cooperative. The encouraging news is that the common scams follow recognizable patterns, and a handful of steady habits — knowing how Medicare actually contacts people, guarding the Medicare number, and reading statements — defeats most of them. This 2026 guide walks through how to avoid Medicare scams calmly and factually: what the frequent schemes look like, how legitimate contact differs from fraudulent contact, and exactly where to report anything suspicious.
How Medicare actually contacts people
The single most useful fact for spotting scams is knowing how the real program communicates. Medicare conducts its routine business by mail. It does not make unsolicited calls asking for your Medicare number, bank account, or Social Security number, does not send representatives to your door, and does not call to sell or “verify” anything. Plans you are already enrolled in may call you about your existing coverage, and Medicare may call if you have contacted them first and left a message, but cold calls claiming to be “from Medicare” are not how the program operates. Insurance agents are also bound by marketing rules: they may not call or visit uninvited to sell Medicare plans, and legitimate agents work through appointments you have agreed to. Holding every unexpected contact up against this baseline resolves most situations before they start.
Unsolicited calls and impersonation
The most common pattern is the impersonation call: someone claims to be from Medicare, Social Security, or a “Medicare department,” often with a caller ID spoofed to look official. The caller typically has a plausible reason for needing your Medicare number — updating records, confirming eligibility, activating benefits — and may already know some of your personal details, which can make the call feel legitimate. Variations include claims that your benefits will lapse unless you confirm information, offers of gift cards or grocery allowances, and transfers to a “supervisor” to add credibility. The pattern to notice is not the story, which changes constantly, but the request: an unexpected caller wants your Medicare number or other personal information. Ending the call is always an acceptable response, and anyone unsure can hang up and call Medicare directly using the number on the back of their Medicare card or official mailings.
The “new card” scheme
A long-running variant tells beneficiaries that Medicare is issuing new cards — plastic cards, chip cards, “updated” cards with new security features — and that a fee or identity verification is needed to receive one. Medicare cards are issued free of charge, and when the program has genuinely updated cards in the past, replacements were mailed automatically without any action, payment, or phone verification required. Any contact that ties a Medicare card to a fee, a bank account, or an over-the-phone identity check follows the scam pattern, whatever the details. A lost card can be replaced for free through Social Security or a Medicare online account.
Medical equipment and testing fraud
Durable medical equipment (DME) fraud works differently: instead of stealing money from you directly, it uses your Medicare number to bill the program. Typical setups include calls or ads offering “free” braces, back or knee supports, glucose monitors, or other equipment “covered by Medicare,” and offers of free genetic tests, cardiac screenings, or COVID-era test kits in exchange for a Medicare number, sometimes at health fairs or through door-to-door visits. Once the number is captured, suppliers bill Medicare for equipment or tests that were never ordered by your doctor, may never arrive, or arrive unwanted. Beyond the cost to the program, these claims enter your medical record and can complicate coverage later — for instance, if Medicare’s records show you already received an item you genuinely need. Equipment and tests that Medicare covers are ordered through your own doctor, not through strangers offering them for free.
Fake plan representatives and enrollment pressure
Around the fall enrollment season, another pattern picks up: callers or visitors posing as plan representatives who push for an immediate enrollment decision, ask for banking details to “set up premium payments,” or misrepresent a plan’s benefits to capture a signup. Legitimate plan marketing is regulated — agents cannot claim to represent Medicare itself, cannot enroll you through an unsolicited call or visit, and are not permitted to pressure an on-the-spot decision. A genuine plan or agent will let you take time, provide written materials, and let you verify the plan independently on Medicare’s plan comparison tool. Any pitch built on urgency or secrecy fails that test. Unwanted enrollment changes, if they do happen, can be reported and corrected, so even this scenario is recoverable rather than catastrophic.
Treat your Medicare number like a credit card
The Medicare number is the asset every one of these schemes is trying to reach, so the protective habits center on it. Share it only with your doctors, pharmacists, other treating providers, your insurers, and trusted people who help manage your care — and not with anyone who contacts you unexpectedly, however official they sound. Carry the card only when you need it, such as to a first appointment, and consider keeping it stored safely otherwise. Do not let anyone else use your number, even someone claiming it will get them or you a free benefit; letting others bill under your number is itself a form of fraud that lands in your records. If you believe your number has been compromised, it can be reported and, where necessary, replaced — an inconvenience, not an emergency.
Read your statements: the habit that catches fraud
Most Medicare fraud is eventually caught because someone read a statement. People with Original Medicare receive a Medicare Summary Notice, and plan enrollees receive an Explanation of Benefits; both list the services and items billed under your number. A brief monthly or quarterly review looking for three things — providers you never saw, services or equipment you never received, and dates that do not match your visits — is the most effective fraud detection available to any beneficiary. Keeping a simple record of appointments and tests, even on a calendar, makes the comparison quick. Not every discrepancy is fraud; billing errors happen, and a call to the provider’s office resolves many of them. But unexplained charges that a provider cannot account for are exactly what the reporting channels below exist for.
How to report suspected Medicare fraud
Reporting is straightforward and free, and it helps protect other beneficiaries as well as the program. The Senior Medicare Patrol (SMP) is a national, grant-funded program with trained teams in every state that help beneficiaries prevent, detect, and report Medicare fraud; you can find your state’s SMP at smpresource.org, and its counselors will walk through your statements and handle referrals with you. Suspected fraud can also be reported directly to the Department of Health and Human Services Office of Inspector General at oig.hhs.gov, which operates the federal fraud hotline. Billing questions and suspicious activity can additionally be raised with Medicare itself through the contact information printed on your Medicare Summary Notice or at Medicare.gov. When reporting, it helps to have the statement in front of you, along with the provider name, the date of service, and the item or service in question.
Final thoughts
Avoiding Medicare scams does not require suspicion of everyone or constant worry. It requires knowing a few fixed facts — Medicare does its business by mail, never charges for cards, and does not cold-call for your number — and keeping two habits: guard the Medicare number the way you guard a credit card, and read your statements. The schemes change their scripts every year, but they all still need the same thing from you, and declining to provide it costs nothing. When something does look wrong, the Senior Medicare Patrol and the HHS Office of Inspector General exist precisely to take the report, and using them is a service to every other person on the program.
