Different Bait, Same Hook: What Every Medicare Scam Is Really After
The phone rings on a Tuesday afternoon. The voice is friendly, a little official. Medicare is sending out new cards, she says, the plastic kind with a chip in them, and she just needs to confirm your number to get yours in the mail.
There is no new card. There is no chip. Medicare didn't call you. But if you read her your number, a stranger now holds the key to your health benefits, and somewhere a bill is already being written in your name.
The story on the phone barely matters. This year it's a chip card. Last year it was a free COVID test. At the county health fair it's a cheek swab that supposedly checks you for cancer. The bait changes with the headlines. The hook underneath never does: every one of these is a play for your Medicare number.
To a scammer, that number is worth more than your credit card. A stolen credit card gets canceled the moment you notice. A Medicare number can be billed quietly, over and over, for braces you never wore and tests you never took, while you have no idea anything is wrong.
The people who see it first
The early warnings tend to come from a quiet corner of the system most people have never heard of: the Senior Medicare Patrol. These are largely retired volunteers, many of them on Medicare themselves, who sit down one-on-one with beneficiaries to sort out a confusing bill or a suspicious phone call. Because they're talking to real people all day, they often spot a new scam weeks before it makes the news.
One detail from those conversations should change how you handle your own mail. As a New York Senior Medicare Patrol director put it to AARP, the only reason many of these scams get caught at all is that someone sat down and actually read their Medicare statement. The fraud was invisible until a person looked.
Which is oddly comforting. Catching them takes no cleverness, only someone willing to look.
The disguises showing up right now
Senior Medicare Patrols across the country have been reporting the same handful of schemes, dressed up in different clothes:
-
The "free" COVID test. Someone calls offering to mail you a test, then bills Medicare as if they sent a pile of them and pockets your number for later. In one 2023 federal takedown, the HHS Office of Inspector General charged 18 people in nine states over more than $490 million in COVID-related false billing. (If you actually want free tests, the real ones come from covid.gov/tests.)
-
Diabetes supplies you never ordered. Charges for continuous glucose monitors have been turning up on the statements of people who don't have diabetes and never received a device. The scammer gets paid; you get a line item you can't explain.
-
The knee brace in the mail. An old favorite. Hand over your number and a cheap brace shows up, the kind you could buy at any drugstore, while Medicare is charged for an expensive one. Sometimes no brace arrives at all.
-
The cheek swab for "cancer risk." At a health fair or over the phone, someone offers a genetic test and says they just need your Medicare number to cover it. Medicare rarely pays for these, so the claim gets denied and the cost can land on you. This isn't small: a 2019 federal case known as Operation Double Helix charged 35 people over roughly $2.1 billion in fraudulent genetic testing claims, and a single denied test can run around $10,000.
-
"Extra benefits" that are really hospice. This one is cruel. People are offered perks like home cleaning, a visiting nurse, or a shower chair, and unknowingly get signed up for hospice care they don't need. A crooked doctor signs off, Medicare pays out, and the victim later finds their legitimate, non-hospice claims being denied.
-
The Medicaid "you'll lose your coverage" call. Tied to the unwinding of pandemic-era Medicaid rules, callers tell people they have to pay up or hand over personal details or risk losing their coverage. Medicaid doesn't work that way.
-
The new chip card. The Tuesday afternoon call. A caller claims a new plastic or chip card is coming and asks for money or your number to send it.
-
The surprise telehealth bill. A sales call turns into a "telehealth consult" you never had, quietly added to your Medicare bill, sometimes bundled with one of the schemes above.
The one habit that catches almost all of them
Every scheme on that list shares one weakness. The fraud happens later, on paper, in a charge billed to your number after you've hung up and forgotten the whole thing.
Which means the single most useful thing you can do takes about ten minutes every few months: read your Medicare Summary Notice.
If you have Original Medicare, that notice arrives by mail every three months and lists every service billed to you. (If you'd rather not wait, you can see your claims anytime by logging into your account at Medicare.gov.) You're looking for one thing: a service, a date, a device, or a doctor's name you don't recognize. A glucose monitor you never got. A brace you never wore. A "consult" that never happened.
Most people file that notice straight in the recycling. The folks who read it are the ones who catch the fraud while it's still small.
What Medicare will never do
It's easier to spot a fake when you know how the real thing behaves. A few rules you can lean on:
- Medicare won't call you out of the blue. If you didn't set up the appointment, the "Medicare representative" on the line isn't one.
- Your card is free, and it's paper. There's no plastic version, no chip, and nobody will ever ask you to pay for a replacement. Need a new one? You can print it from your Medicare account whenever you want.
- Medicare already has your number. Anyone who calls asking you to "confirm" or "verify" it is fishing.
When in doubt, the move is the same every time. Hang up. Don't call back the number they gave you. Call the number printed on the back of your own Medicare card, or 1-800-MEDICARE, and ask whether anything's actually going on.
If something already looks off
If a charge on your statement doesn't add up, or a call left you uneasy, you have people to call:
- 1-800-MEDICARE (800-633-4227) to report a suspicious charge or claim.
- Your Senior Medicare Patrol at 877-808-2468, where a volunteer can help you read a confusing notice and report real fraud.
- The AARP Fraud Watch Network Helpline at 877-908-3360 if you want to talk through what happened.
Reporting it protects more people than you. The volunteer who takes your call is how the next scam gets spotted before it reaches your neighbor.
So when the phone rings on Tuesday and the friendly voice tells you your new chip card is ready, you already know the script. There is no chip. There is no new card. The right response is gloriously boring: hang up, dig out your last statement, and call the number on your own card. These scams only work with your cooperation. A little stubbornness is the whole defense.
