Medicare Open Enrollment Scam: What to Do If You Already Shared Your Medicare Number

The Call Is Fake — Medicare Doesn't Cold-Call You to 'Confirm' Your Plan

During Medicare Open Enrollment (October 15 – December 7 each year), scammers ramp up calls, texts, and even door-to-door visits impersonating Medicare, a Medicare Advantage plan, or a 'Medicare benefits specialist.' The pitch usually claims you'll lose your coverage, miss a better plan, or forfeit a rebate unless you 'confirm' your Medicare number, Social Security number, or bank details right now.

Medicare itself does not call beneficiaries uninvited to sell plans or confirm personal information. Legitimate agents can only contact you if you've given prior permission, and a genuine plan comparison never requires you to disclose your Medicare number, Social Security number, or banking details over an unsolicited call.

How the Scam Typically Works

Common versions of the scam include: a caller claiming to represent 'Medicare' offering a free genetic test, back brace, or other item shipped in exchange for your Medicare number (which is then used to bill Medicare fraudulently for products you never received or needed); a caller claiming your current plan is being discontinued and you must 're-enroll' immediately by providing your number; and a caller offering a too-good cash-back or premium-reduction 'deal' that requires bank details to process.

Because your Medicare number functions similarly to an insurance ID, scammers who obtain it can bill Medicare for fraudulent equipment or services in your name — a form of fraud that can take months to untangle and may temporarily affect your own coverage while it's investigated.

What to Do Right Now If You Already Shared Information

1. Call Medicare directly at 1-800-MEDICARE (1-800-633-4227) to report the call and ask them to flag your account for review.

2. Review your Medicare Summary Notices (or check claims online at MyMedicare.gov) over the coming weeks for any billed services, equipment, or tests you didn't actually receive.

3. If you gave out your Social Security number or bank details, place a fraud alert with Equifax, Experian, and TransUnion, and monitor your bank statements closely.

4. Report the scam to the Senior Medicare Patrol (SMP) at smpresource.org, which specifically investigates Medicare fraud, and to the FTC at reportfraud.ftc.gov.

5. If you agreed to switch plans on the call, contact your current plan directly (using the number on your card, not the caller's number) to confirm nothing has actually changed, and to reverse it if it has.

How to Spot the Next One

Medicare will never call you uninvited to sell a plan, confirm your number, or offer free equipment in exchange for your Medicare number. If a call pressures you to act immediately, offers something 'free' in exchange for your Medicare number, or claims your coverage will lapse unless you confirm details right now, hang up and call 1-800-MEDICARE yourself to check.
