Fake Medicare Supplement Plan Scam
Scammers sell bogus Medigap or Medicare Advantage-style supplement plans to older adults, collecting premiums for coverage that is never real or does not exist at all.
Last reviewed: 5 July 2026
What this scam is
Fake Medicare supplement plan scams target people eligible for Medicare with offers of supplemental coverage — often described using real terminology like 'Medigap', 'Plan G', or 'Medicare Advantage' — sold by callers or door-to-door agents who are not licensed to sell Medicare products, or who fabricate coverage entirely. The pitch typically promises to fill the gaps left by original Medicare, cover out-of-pocket costs, or reduce premiums, at a price that seems attractive relative to genuine plans.
Because Medicare's structure genuinely involves supplemental options sold by licensed private insurers, and because the enrollment landscape includes numerous real plans with confusingly similar names, fraudulent sellers can operate with a high degree of plausibility. Victims often do not discover the fraud until they attempt to use the supposed coverage at a doctor's office, hospital, or pharmacy and find no record of it.
This scam disproportionately affects Medicare-eligible adults, a population frequently targeted because open enrollment periods and the complexity of Medicare plan options create genuine confusion that scammers can exploit.
How it works
Contact is typically made by phone, in a health fair or community event, or through a door-to-door visit, often timed around Medicare's annual open enrollment period. The seller presents themselves as a Medicare specialist or agent and describes a supplement plan that covers deductibles, coinsurance, or additional benefits like dental and vision, often for a monthly premium below what comparable licensed plans charge.
The victim provides their Medicare number, Social Security number, and banking information to 'enroll'. In some cases, an enrollment confirmation or membership card is sent, giving the appearance of legitimacy. In others, nothing further is sent at all, and the scammer simply collects the enrollment information for use in a broader identity theft or Medicare billing fraud scheme, in addition to or instead of collecting premium payments.
When the victim visits a doctor or pharmacy expecting the supplemental coverage to reduce their out-of-pocket cost, the provider has no record of the plan. In parallel, the victim's Medicare number may be used to submit fraudulent billing claims for services never received, which can take considerable time and effort to identify and correct on the victim's official Medicare record.
Why this scam works
Medicare's plan landscape is genuinely complex, with many real private insurers offering similarly named products with different rules, and this complexity means an unfamiliar or unlicensed seller does not immediately stand out as suspicious. The annual open enrollment period creates a compressed window during which real advertising volume is high, giving fraudulent offers cover to blend in with legitimate marketing.
Older adults are often navigating fixed incomes and rising healthcare costs, which makes an offer of lower premiums or broader coverage than their current plan appealing enough to reduce scrutiny of the seller's credentials. Because a Medicare number functions similarly to a Social Security number in terms of sensitivity, providing it during a fraudulent enrollment call also exposes victims to downstream identity theft and billing fraud that may not surface for months.
A typical pattern
During Medicare's open enrollment period, a Medicare-eligible adult receives an unsolicited phone call describing a new supplement plan that covers costs their current plan does not, at a lower monthly premium. The caller asks for their Medicare number and bank details to complete enrollment over the phone. No card or documentation is ever received. Months later, the person visits a specialist and is told their current plan shows no supplemental coverage on file. Separately, they later discover unfamiliar claims processed under their Medicare number for services they never received.

How to verify before you act
Verify that anyone selling a Medicare supplement, Advantage, or Part D plan is licensed in your state by checking your state insurance department's producer license lookup, and confirm the specific plan is listed on the official Medicare Plan Finder tool. Never provide your Medicare number to anyone who contacts you unsolicited by phone, at a community event, or at your door — Medicare and legitimate agents do not require you to disclose your number to receive general plan information.
If you are unsure whether an offer is genuine, contact your State Health Insurance Assistance Program (SHIP) or the official Medicare helpline directly, using contact information found independently rather than any number given by the seller, to confirm the plan and the agent's standing before enrolling or providing any personal information.
