Protect Your Medicare Number: Simple Steps to Avoid Fraud

COLUMBIA, Tenn. — Your Medicare number is one of the most valuable pieces of personal information you own. In the wrong hands, it can be used to bill Medicare for services you never received, drain program dollars, and create a paperwork mess that takes months to untangle.

The good news: a few simple habits go a long way. Here's how to guard your number, spot common scams, and know exactly what to do if something feels off.

Treat your Medicare card like a credit card

Your Medicare Beneficiary Identifier (MBI) — the 11-character number on your red, white, and blue card — should be shared only with people you trust to give you medical care. That means your doctor, your pharmacist, your hospital, and licensed insurers you already work with.

A few habits worth building:

• Carry your card only when you need it for an appointment.
• Keep a photo or copy in a secure spot at home instead.
• Never post a picture of your card on social media, even with the number blurred.
• Shred old Medicare paperwork before tossing it.

Medicare will never call, text, email, or knock on your door asking you to "verify" or "reactivate" your number. If someone does, that's a red flag.

Know the scams making the rounds

Fraudsters keep changing their pitch, but most schemes fall into a few familiar buckets:

• "Free" braces, genetic tests, or medical equipment. A caller offers a back brace, knee brace, or DNA cheek swab at "no cost" and just needs your Medicare number. Medicare then gets billed for expensive items you may never receive — or don't need.
• Fake Medicare representatives. Someone claims to be from Medicare, Social Security, or "your plan" and says your card is being updated. There is no new card coming. Hang up.
• Enrollment pressure calls. Around the Annual Enrollment Period (Oct. 15 – Dec. 7) and Medicare Advantage Open Enrollment (Jan. 1 – March 31), scam calls spike. Real agents cannot cold-call you unless you've given permission.
• Pharmacy or drug plan "verifications." Callers may reference Part D changes — like the $2,100 out-of-pocket cap in 2026, rising to $2,400 in 2027 — to sound official. Legitimate updates don't require you to hand over your number by phone.

Read your statements — that's where fraud shows up

Whether you're on Original Medicare or a Medicare Advantage plan, you'll get regular summaries of what was billed in your name:

• Medicare Summary Notice (MSN) for Original Medicare, mailed every three months.
• Explanation of Benefits (EOB) from your Medicare Advantage or Part D plan.

Compare these to your own calendar and receipts. Look for services you didn't receive, duplicate charges, or providers you don't recognize. Small, odd charges are often how fraud is first spotted.

You can also create a free account at MyMedicare.gov to see claims sooner than the paper notices arrive.

What to do if you think your number is compromised

Columbia is in Maury County, and Tennessee residents have several free, trustworthy places to turn:

1. Call 1-800-MEDICARE (1-800-633-4227). Report suspicious claims or calls. 2. Contact the Tennessee Senior Medicare Patrol (SMP). SMP is a federally funded program that helps beneficiaries prevent, detect, and report Medicare fraud. Services are free and confidential. 3. Call your local SHIP (State Health Insurance Assistance Program). Tennessee's SHIP counselors offer one-on-one help with Medicare questions — no sales pressure. 4. Report identity theft at IdentityTheft.gov if your Medicare number was stolen alongside other personal information.

If you gave out your number by mistake, don't panic — but do act quickly. Medicare can flag your account and, in some cases, issue a new MBI.

A quick word on enrollment season

Fraud tends to rise when Medicare is in the news. As 2027 changes take shape — including the $2,400 Part D out-of-pocket cap and the continued Medicare Prescription Payment Plan for smoothing drug costs monthly — expect scammers to name-drop these updates.

Remember: understanding a new rule and needing your Medicare number to activate it are two very different things. The rules apply automatically. No phone call required.
