Medicare Open Enrollment scams: spot the calls before they cost you
Enrollment season — October 15 – December 7, 2026 — brings its yearly wave of fake “Medicare” calls, texts and “licensed agents”, and the dialing starts weeks before the window opens. Here’s the real calendar, how the scams work, how to shut a call down, and how to get off the lists the scammers are dialing from.
Open Enrollment 2026 runs October 15 – December 7, and nothing in it gets decided on an inbound call. Medicare doesn’t cold-call, no plan may pitch next year’s coverage before October 1, and agents may not ring you unless you asked them to. If someone calls about your plan, a new card, a refund or “free benefits” — hang up and dial 1-800-MEDICARE yourself; anything real will be there. Never give your Medicare number, SSN or bank details to an inbound caller. To stop the calls rather than just screen them, remove your phone and address from the data-broker and lead-generation sites the calling lists are built from.
1. Why the calls flood in every fall
Medicare Open Enrollment runs October 15 – December 7, 2026, and it’s the one time of year when a stranger talking about your health plan doesn’t sound strange. Scam operations prepare for it like a retail holiday: they buy lists of seniors — name, age, phone, address, sometimes the current insurer — from data brokers and insurance lead-generation sites, and start dialing in early September, before legitimate plan marketing is even allowed to begin. If the calls feel targeted, that’s because they are: the data came from a list someone sold.
2. The 2026 calendar, and what a real plan may do
The season has fixed dates, and they are your best lie detector. September: plans mail current members the paperwork for next year — that’s notices, not sales calls. October 1: the earliest date a plan is allowed to market its 2027 offerings at all. October 15 – December 7: you can enroll or switch; whatever you choose starts January 1, 2027. January 1 – March 31: a second window, only for people already in a Medicare Advantage plan. Two rules sit on top of that calendar: plans and their agents may not call you unless you consented or contacted them first, and they may not show up at your door uninvited. A September pitch, a cold call, or a knock you didn’t schedule is already outside the rules — before you weigh a word of the offer.
3. The scams making the rounds
The scripts change, the goals don’t: your Medicare number, your Social Security number, or a payment. The staples: a “new Medicare card” that requires you to verify your number first; a “your plan is being cancelled — act today” pressure call; free-sounding offers (genetic tests, back braces, grocery allowances) that just need your Medicare number; and “you’re owed a refund” calls that need your bank details to “deposit” it. Around Open Enrollment, add fake “licensed agents” pushing you to switch to a plan you never asked about — sometimes enrolling people without consent. This season’s wording to listen for: calls that introduce themselves as “the Medicare enrollment center” or “your benefits coordinator”, which sound official and are neither — and a local-looking number on the display, which costs the caller nothing to fake.
4. Red flags that end the call
Medicare doesn’t cold-call to sell or verify anything — an unexpected “this is Medicare” call is already the answer. No legitimate caller asks you to pay by gift card, wire or crypto, and no real agent needs your full Social Security number to “check eligibility”. Caller ID saying “Medicare” or a local number means nothing — spoofing is trivial. And urgency is the tell that ties them all together: real enrollment gives you weeks; scammers give you minutes.
5. What to do when the phone rings
Hang up — politeness is the hook these scripts rely on. If you think the issue might be real, call 1-800-MEDICARE (1-800-633-4227) yourself or log in at medicare.gov: anything genuine will be visible there. Want help comparing plans during Open Enrollment? Use medicare.gov’s Plan Finder or your state’s free SHIP counselor — people you called, not people who called you. Never confirm your Medicare number, SSN or bank details to an inbound caller, even one who already knows some of your information.
6. Cut the calls off at the source
Filters help: register at donotcall.gov, enable the carrier’s free scam filter (AT&T ActiveArmor, Verizon Call Filter, T-Mobile Scam Shield) and the phone’s own screening — our stop-spam-calls guide has the full setup. But the durable fix is upstream: the calling lists are built from data-broker and people-search listings, so removing your (or your parents’) phone and address from those sites shrinks every future list. Start with the data-broker opt-out guide or our phone-number removal guide.
7. If information already slipped out
Gave a Medicare number to a caller? Report it at 1-800-MEDICARE, then read each Medicare Summary Notice for services you never received — billing your number for phantom equipment is the standard play. Your state’s Senior Medicare Patrol (smpresource.org) will read the statements with you for free, and drug- or Advantage-plan fraud has its own line: 1-877-772-3379. File the call at reportfraud.ftc.gov. If the SSN went too, freeze credit with all three bureaus (free, and it blocks new accounts). Then remove the exposed contact data from broker sites so the same lists don’t light up again next enrollment season — managing this for an aging parent is normal; our guide for protecting elderly parents covers doing it on their behalf.

When is Medicare Open Enrollment in 2026?
October 15 through December 7, 2026. Whatever you pick in that window takes effect January 1, 2027, and the plan has to receive your request by December 7. One more window follows for people already in a Medicare Advantage plan: January 1 – March 31, when you can switch to another Advantage plan or back to Original Medicare. Nothing outside those dates is urgent, which is why "you have to decide today" is a scam line no matter how the caller says it.
Can a Medicare plan or an agent call me out of the blue?
No. Under the federal marketing rules, plans and their agents may not make unsolicited calls — a call is only allowed if you gave consent or contacted them first (returning your call or answering a reply card you sent counts). Uninvited door-to-door visits are barred the same way unless you scheduled the appointment. And plans cannot pitch next year’s coverage at all before October 1. So a September sales call about your 2027 plan is breaking the rules before it even gets to the pitch.
Does Medicare ever call me?
Almost never uninvited. Medicare may call back if you left a message with 1-800-MEDICARE, or a plan you already belong to may contact you about your coverage — but Medicare does not cold-call to sell plans, "verify" your number, or offer refunds. An unexpected call that opens with Medicare is the tell in itself.
How do I know if a call about my Medicare plan is real?
Don’t decide on the call. Hang up, then dial 1-800-MEDICARE (1-800-633-4227) yourself or log in at medicare.gov. If a licensed agent you actually requested is calling, they can verify through the official channel you initiated. Caller ID that shows "Medicare" proves nothing — spoofing the name is standard practice in these operations.
What happens if a scammer got my Medicare number?
Call 1-800-MEDICARE right away and report it, then watch your Medicare Summary Notices for services or equipment you never received — that’s how the number gets monetized. Report the fraud at reportfraud.ftc.gov too. If your Social Security number was also given, add a free credit freeze with the three bureaus.
Who do I report a Medicare scam call to?
Start with 1-800-MEDICARE (1-800-633-4227). Your state’s Senior Medicare Patrol takes these reports too and will help you read the statements afterwards — find yours at smpresource.org. If the call was about a Medicare Advantage or drug plan, there is a dedicated line: 1-877-7SAFERX (1-877-772-3379). Billing fraud you spot on a statement goes to the HHS Inspector General at oig.hhs.gov, and the call itself can go to reportfraud.ftc.gov.
Why do the scam calls explode every October?
Open Enrollment — October 15 to December 7, 2026 this year — is the one window when switching plans is normal, so a pressure call fits the season perfectly. Scam operations buy calling lists in advance: age, phone, address and even the current insurer are for sale from data brokers and insurance lead-generation sites. The dialing ramps up from early September, weeks before real plans are allowed to market anything.
How do I stop these calls for my parents?
Register their number on the Do Not Call Registry, turn on the carrier’s free scam filter and the phone’s built-in spam screening — and then remove their listings from data brokers, which is where the calling lists come from in the first place. You can run removals on a parent’s behalf; our guide for protecting elderly parents walks through it.
