Protecting Yourself From Medicare Identity Theft: A Practical Guide

If someone steals your Medicare number, they can bill Medicare in your name, drain your benefits, and expose your personal information. Many scams are subtle and target older adults directly, often by phone, mail, or even at health fairs. The good news: a few consistent habits go a long way toward protecting yourself.

Know What Your Real Medicare Contacts Look Like

Scammers often pose as Medicare or “the government.” Protect yourself by knowing how Medicare normally behaves:

• Medicare doesn’t call to demand your number out of the blue. Unsolicited calls asking to “verify,” “reactivate,” or “confirm” your Medicare number are almost always scams.
• Medicare won’t threaten to cancel your coverage if you don’t give information immediately.
• Legitimate mail from Medicare arrives in official envelopes and does not ask you to send your Medicare card or photocopies of it.

If you’re unsure about a call or letter, hang up or set it aside, then use the phone number on the back of your Medicare card to confirm whether it was real.

Guard Your Medicare Card Like a Credit Card

Treat your Medicare Beneficiary Identifier (MBI) as sensitive financial information.

• Carry your card only when you know you’ll need it (for example, a doctor visit).
• Don’t share your Medicare or Social Security numbers with anyone who contacts you unexpectedly.
• Never post photos of your card or Explanation of Benefits online or send them by unencrypted email or text.
• If you misplace your card or think someone copied it, contact Medicare right away to request a new number.

Only give your Medicare number to trusted providers, pharmacies, or insurers that you already know or have verified.

Spot Common Medicare Identity Theft Scams

Scammers constantly change tactics, but their themes are similar. Be skeptical of anyone offering:

• A “free genetic test,” cancer screening, or medical equipment in exchange for your Medicare number.
• A “new plastic Medicare card” or upgraded card that requires you to confirm your number or bank account.
• A “refund” or “rebate” that supposedly requires your Medicare number to process.

If it sounds too good to be true or uses pressure and urgency, pause and verify independently.

Check Your Medicare Records Regularly

You’re more protected when you spot misuse early.

• Review your Medicare Summary Notices (MSNs) or other benefit statements. Look for services, tests, or equipment you don’t recognize.
• Keep a short list of your recent appointments and procedures so you can compare them with what’s billed.
• Question charges from providers you’ve never seen or locations you’ve never visited.

Call your provider about anything unfamiliar. If it still doesn’t make sense, report it to Medicare.

What To Do If You Suspect Medicare Identity Theft

Act quickly if you think your Medicare number has been stolen or misused:

1. Contact your doctors or suppliers to confirm whether the service was real.
2. Report the issue to Medicare using the number on your card and ask about getting a new Medicare number.
3. Monitor your statements more often for a while to catch any new fraudulent activity.
4. Consider placing fraud alerts or monitoring on your broader financial accounts if other personal data may have been exposed.

Staying safe doesn’t require complicated tools—just consistent habits: protect your number, verify who’s contacting you, and review your records. Those steps make you a much harder target for Medicare identity thieves.
