Medicare Scam: How to Recognize the Calls, Texts, and Mailers Targeting Seniors

Published by ScamSave | CISSP-Authored | Category: Scam Awareness

The call sounds completely official. A friendly voice says Medicare is issuing new cards and needs to verify your information. Or that your benefits will be suspended unless you confirm your Medicare number today. Or that you qualify for free medical equipment — all you need to do is provide your details so they can process the shipment.

None of it is real. But millions of Americans receive calls exactly like this every year — and the financial and personal damage when someone falls for one goes far beyond a single phone call.

Medicare loses an estimated $60 billion annually to fraud and scams. Adults 60 and older reported $2.4 billion in fraud losses in 2024 — a 300% increase from 2020 — with government impersonation scams, the category that includes Medicare fraud, accounting for $789 million of that total. Phone call scams, the most common method used in Medicare fraud, produce a median individual loss of $2,210 per incident.

This guide covers every major Medicare scam type in use today, what the real Medicare program will never do, exactly what to do if you or a family member has been targeted, and how to protect a senior you care about before a scammer ever calls.

What Medicare Will Never Do

Memorize this section. Share it with every senior you know. The real Medicare program has clear, published policies about how it contacts beneficiaries — and scammers violate every one of them.

If a caller is doing any of these things, you are talking to a scammer. Hang up immediately. Do not provide any information. Do not call back the number that called you.

Why Medicare Beneficiaries Are Targeted So Heavily

Medicare fraud is not random. It is specifically engineered to exploit the Medicare system and its beneficiaries. Understanding why helps seniors and their families recognize the environment they’re operating in.

• The Medicare number is extraordinarily valuable to fraudsters. A Medicare Beneficiary Identifier (MBI) can be used to bill Medicare for services, equipment, and procedures that were never provided — generating fraudulent reimbursements that flow to the scammer while the beneficiary’s coverage is silently drained or their record corrupted.
• Real Medicare changes create confusion that scammers exploit. Every year during Open Enrollment (October 15 through December 7), millions of seniors are actively comparing plans and making coverage decisions. Scammers time their highest-volume campaigns to this window. Coverage changes, plan eliminations, and benefit modifications give scammers a ready-made script: “Your plan is changing and you need to act now.”
• Seniors are more likely to answer the phone. Research consistently shows that older adults are more likely to engage with unsolicited calls, making phone-based Medicare scams particularly effective.
• AI has made calls harder to distinguish from real ones. Voice cloning technology can now generate calls that mimic official Medicare representatives with high accuracy. See our full guide: AI Voice Cloning Scam: How Scammers Are Faking Voices.

The Most Common Medicare Scams

1. Fake Medicare Card Renewal Scam

A caller says Medicare is issuing new cards and that you need to verify your Medicare number, Social Security number, or date of birth to receive yours. Sometimes they claim your current card is expiring. Sometimes they say there’s a problem with your account that needs to be resolved before the new card can be sent.

Medicare does not call beneficiaries to issue new cards. New cards are mailed directly to your address on file without any phone verification required. Anyone calling to “process” a new Medicare card is a scammer attempting to steal your Medicare number and personal identity information.

2. Benefits Cancellation Threat

A caller — sometimes robotic, sometimes a real person — tells you that your Medicare coverage will be suspended, canceled, or reduced unless you confirm your information or take action immediately. The threat of losing health coverage is deliberately chosen to create panic in seniors who depend on Medicare for essential medical care.

Medicare does not cancel benefits over the phone without extensive written notice and formal appeal processes. A call threatening immediate benefit loss is a scam without exception.

3. Free Medical Equipment and Supply Scams

A caller offers free back braces, knee braces, wheelchairs, catheters, diabetic supplies, or other durable medical equipment — all “covered by Medicare, at no cost to you.” All they need is your Medicare number to process the order. Sometimes they follow up with a home visit to deliver the equipment and collect additional information.

What actually happens: the scammer uses your Medicare number to bill Medicare for equipment you may never receive, or receive at far lower quality than described. This is one of the largest categories of Medicare billing fraud. Medicare Part D alone saw $3.58 billion in improper payments in 2024. If you receive unsolicited equipment in the mail, do not use it and report it immediately.

4. Fake Medicare Advantage Plan Switching

A caller — often during Open Enrollment — pressures you to switch your Medicare Advantage plan immediately, claiming your current plan is being discontinued or that a new plan offers dramatically better benefits. In some cases, agents enroll beneficiaries in new plans without checking whether their doctors are in-network or their medications are covered — or even without the beneficiary’s full informed consent.

Legitimate Medicare plan representatives are licensed and required to give you time to review plan details. Anyone using high-pressure tactics, false urgency, or claims that “you’ll lose coverage if you don’t switch today” is operating outside the law.

5. Fake “Medicare Flex Card” Scams

Advertisements — sometimes on social media, sometimes via mailer — claim you qualify for a “Medicare Flex Card” worth hundreds or thousands of dollars for groceries, utilities, or household expenses. All you need to do is call a number or visit a website to claim it. These ads target low-income seniors with compelling but fabricated benefit claims. While some legitimate Medicare Advantage plans do offer supplemental benefit cards, they are never obtained through unsolicited ads promising specific dollar amounts.

6. Fake Government Mailers

Official-looking envelopes arrive marked “Important Medicare Notice” or “Medicare Enrollment Document” — sometimes with government-style formatting and seals. Inside is a request to call a number, provide personal information, or enroll in a plan. Real Medicare mail comes from the Centers for Medicare and Medicaid Services (CMS) with a return address that reflects this. Check the return address on every piece of Medicare-related mail before calling any number printed on it.

7. Medicare Billing Fraud Against Your Account

This scam happens without a call. A fraudster uses a stolen Medicare number — obtained through a previous data breach, phishing attack, or scam call — to submit false claims to Medicare for procedures, equipment, or services that were never provided. You won’t know it happened until you review your Medicare Summary Notice (MSN) and see charges for care you never received.

Reviewing your MSN every time one arrives is one of the most effective ways to catch this fraud early. Report discrepancies to 1-800-MEDICARE immediately.

8. Fake Medical Testing Vans

A van or popup booth in a parking lot, senior center, or community event offers “free” health screenings — blood tests, genetic testing, cardiovascular testing — and asks for your Medicare card to “process the results.” The tests may be unnecessary, low-quality, or never actually analyzed. The real goal is your Medicare number and personal information. Legitimate community health screenings do not require your Medicare card at a parking lot booth.

Red Flags: How to Recognize a Medicare Scam in Real Time

• Any unsolicited call, text, or email asking for your Medicare number. Medicare already has it. No legitimate contact requires you to provide it again over the phone.
• Urgency and threats. “Your benefits will be canceled today unless you act” is manipulation, not a real deadline.
• Free equipment or supplies in exchange for your Medicare number. Your Medicare number is not a form of payment — it is your identity in the healthcare system.
• A caller who already “knows” part of your information and asks you to confirm the rest. Scammers often use partial data obtained from previous breaches to establish false credibility before fishing for the rest.
• High-pressure plan switching during Open Enrollment. Legitimate agents will give you time to review details and compare options.
• A mailer, ad, or website promising a Medicare Flex Card for a specific dollar amount. Verify any supplemental benefit claims directly at Medicare.gov or by calling 1-800-MEDICARE.
• An unexpected Medicare Summary Notice showing charges for care you didn’t receive. This is evidence that your Medicare number has already been compromised.

What to Do If You or a Family Member Was Targeted

If You Gave Out Your Medicare Number

Report it to 1-800-MEDICARE (1-800-633-4227) immediately. Ask them to flag your account for potential fraudulent billing activity and to monitor for claims you didn’t authorize. Also contact the Office of Inspector General at 1-800-HHS-TIPS (1-800-447-8477) or submit a report at oig.hhs.gov. Request a replacement Medicare card with a new Medicare Beneficiary Identifier if your number was directly compromised.

If You Gave Out Your Social Security Number

Place a credit freeze at all three credit bureaus — Equifax, Experian, and TransUnion — immediately. File an identity theft report at IdentityTheft.gov to generate a personalized recovery plan. Also enroll in an IRS Identity Protection PIN at IRS.gov/ippin to prevent fraudulent tax returns. Read more about what to do when personal information is compromised in our guide: I Gave a Scammer My Bank Account Number — Here’s What to Do Right Now.

If You Were Enrolled in a Plan Without Your Consent

Call 1-800-MEDICARE and report that you were enrolled in a Medicare Advantage or Part D plan without your knowledge or full consent. You have the right to disenroll and return to your original coverage. The Medicare helpline can walk you through the disenrollment process and timeline.

If You Sent Money

Contact your bank or payment service immediately. If you paid by gift card, call the retailer’s fraud line — some can deactivate unredeemed codes. If you wired money, call your bank and ask them to attempt a wire recall. File reports with the FTC at ReportFraud.ftc.gov and the FBI at IC3.gov.

Report the Scam

• Medicare fraud hotline: 1-800-HHS-TIPS (1-800-447-8477)
• Online report: oig.hhs.gov
• FTC: ReportFraud.ftc.gov
• FBI: IC3.gov

How to Protect Your Medicare Information Going Forward

Guard Your Medicare Number Like a Credit Card Number

Your Medicare Beneficiary Identifier (MBI) is the key to your healthcare identity. Only give it to your doctor, pharmacist, hospital, or other verified healthcare provider at the point of care. Never read it over the phone to an unsolicited caller. Never give it in exchange for anything being offered to you.

Review Your Medicare Summary Notice Every Time It Arrives

Your MSN lists every service, supply, and procedure billed to Medicare under your name. Review it carefully when it arrives — typically every three months, or monthly if you have Part D. Any charge for care you didn’t receive is a potential sign your Medicare number has been used fraudulently. Report discrepancies to 1-800-MEDICARE immediately.

Be Extra Vigilant During Open Enrollment (October 15 – December 7)

This is peak season for Medicare scam calls. Scam call volume spikes sharply during this window as fraudsters exploit the real activity of millions of seniors comparing and switching plans. Be especially skeptical of any unsolicited call, text, or mailer during this period — even one that appears to come from a carrier you already use.

Verify Everything Through Official Channels

If you receive any Medicare-related communication that seems unusual, call 1-800-MEDICARE directly — not the number on the communication you received. If you want to compare plans or understand your benefits, visit Medicare.gov or call the official helpline. Never act on information from an unsolicited contact before verifying it independently.

Talk to the Seniors in Your Life Specifically

Many seniors are unaware that AI technology now enables calls that can mimic official Medicare representatives with near-perfect accuracy. Have a direct conversation with elderly parents, grandparents, or neighbors about what Medicare will and will never ask for. Set up a family safe word so they can verify any urgent call before acting. For a comprehensive caregiver guide, see: How to Protect Elderly Parents from Scams.

Frequently Asked Questions

Does Medicare ever call beneficiaries?

Yes, but only in limited and specific circumstances — such as if you have an open case with Medicare or have previously contacted them and they are returning your call. Medicare does not make cold outbound calls to verify information, sell plans, or offer free equipment. If you receive an unsolicited call claiming to be from Medicare, hang up and call 1-800-MEDICARE directly to verify whether any action is actually needed on your account.

What should I do if I already gave my Medicare number to a scammer?

Call 1-800-MEDICARE immediately and report that your Medicare number may have been compromised. Ask them to monitor your account for fraudulent billing. Also contact the OIG at 1-800-HHS-TIPS. You can request a new Medicare card with a new Medicare Beneficiary Identifier — this is the most definitive step to cut off access for anyone who has obtained your number.

How do I know if Medicare is billing me for something I didn’t receive?

Review your Medicare Summary Notice every time one arrives. It lists every claim billed under your name. You can also check your claims history anytime by logging into your account at Medicare.gov. Any service, equipment, or procedure you don’t recognize should be reported to 1-800-MEDICARE and the OIG at oig.hhs.gov.

Is a Medicare Flex Card legitimate?

Some legitimate Medicare Advantage plans do offer supplemental benefit cards for approved expenses — but they are a plan benefit you enroll in, not something you “claim” through an ad or unsolicited call. Any advertisement promising a Medicare Flex Card for a specific dollar amount to anyone who calls a number should be verified at Medicare.gov or 1-800-MEDICARE before taking any action. Unsolicited Flex Card offers are almost universally scams.

My elderly parent got a call about free knee braces covered by Medicare. Is that a scam?

Almost certainly yes. Unsolicited calls offering free medical equipment in exchange for a Medicare number are one of the most common and most damaging Medicare scam types. Hang up and do not provide the Medicare number. If your parent already provided their number, report it to 1-800-MEDICARE and 1-800-HHS-TIPS immediately.
