Guard Your Medicare Number: How Oxnard Seniors Can Spot Fraud

OXNARD, Calif. — Your Medicare card is small, but it opens a big door. The number printed on it is tied to your health history, your benefits, and billions of taxpayer dollars. That is exactly why scammers want it — and why a few simple habits can keep you safe.

Here in Oxnard, the Ventura County Area Agency on Aging and California's Senior Medicare Patrol (SMP) continue to warn beneficiaries about phone calls, texts, and door-to-door pitches designed to pry loose your Medicare number. The good news: most fraud attempts fall apart the moment you know what to look for.

Why your Medicare number is a target

Think of your Medicare Beneficiary Identifier (the 11-character code on your red, white, and blue card) the way you would think of a credit card number. With it, a dishonest provider or outright thief can bill Medicare for services you never received, order equipment in your name, or enroll you in something you didn't ask for.

Once your number is misused, it can take months to sort out — and in the meantime, fraudulent charges can crowd out coverage you actually need.

The scams making the rounds right now

Fraud tactics shift, but a few keep resurfacing in California:

• "Free" braces, genetic tests, or diabetic supplies. A caller offers something at no cost and just needs your Medicare number to "verify eligibility." Medicare does not cold-call people to offer products.
• Fake plan agents during Fall Open Enrollment. With the Annual Enrollment Period running Oct. 15 – Dec. 7, scammers pose as agents or even as "Medicare" itself. Real Medicare will not call, text, or show up uninvited to sign you up.
• Threats to cancel your benefits. No one from Medicare will threaten to end your coverage if you don't hand over information.
• New card fees. Your Medicare card is free. Anyone charging for a "new" or "upgraded" card is lying.

Simple rules that stop most fraud

Federal fraud investigators and SMP volunteers boil it down to a few habits:

1. Treat your Medicare number like a Social Security number. Share it only with your doctor, pharmacist, licensed insurance agent you contacted, or 1-800-MEDICARE. 2. Never give it out in response to an unsolicited call, text, email, or knock at the door. 3. Check your Medicare Summary Notice (MSN) or your MyMedicare.gov account every month for services or equipment you don't recognize. 4. Keep a simple "medical calendar." Jot down each doctor visit, test, and item you received. It makes suspicious billing easy to spot. 5. If something feels off, hang up. You can always call back using the number on your Medicare card or on medicare.gov.

What's new for 2027 — and why scammers may use it as bait

Real Medicare changes give scammers fresh scripts. Know the facts so you can't be tricked:

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027. No one needs your Medicare number to "activate" it — it applies automatically.
• Part D maximum deductible: $615 in 2026 and $700 in 2027.
• The coverage gap ("donut hole") is gone as of 2025. Drug coverage now has three phases.
• Medicare Prescription Payment Plan: an optional way to spread drug costs across the year in monthly payments. You opt in through your Part D plan, not through a stranger who calls you.
• IRMAA (income-related premium surcharges): kick in above $109,000 for single filers in 2026. Medicare uses IRS data — no one needs to call you to "confirm your income."

If a caller mentions any of these changes and then asks for your Medicare number or bank account, that's your cue to hang up.
