UnitedHealthcare scams

Last updated September 18, 2026

The short answer

UnitedHealthcare scams centre on Medicare Advantage enrollment: a caller offering extra benefits, a "free" grocery or OTC card, or a plan review, who needs your member ID and Medicare number to proceed. UnitedHealthcare does not cold-call to enroll you, and giving out a Medicare number is what makes the call profitable.

UnitedHealthcare is the largest Medicare Advantage carrier in the country, which puts it at the centre of the most aggressive telemarketing environment in US healthcare. Some of the calls are real brokers working on commission; some are unlicensed; and some are outright fraud harvesting Medicare numbers for billing schemes. From the receiving end they sound nearly identical, which is why the rule has to be about what you do, not about telling them apart.

How UnitedHealthcare scams work

1
The "extra benefits" enrollment call
A caller says you qualify for additional benefits — dental, vision, an over-the-counter allowance, a grocery card — under a UnitedHealthcare plan. To "check eligibility" they need your Medicare number and date of birth. Depending on who is calling, this ends in an unwanted plan switch, a sold lead, or a Medicare number used for fraudulent billing.
2
Unauthorised plan switching
A commissioned agent enrolls you in a different plan without a clear, informed agreement. You discover it when your doctor is suddenly out of network or a prescription stops being covered — often in January, after the enrollment window has closed.
3
Member portal phishing
An email or text about a claim, a new ID card, or a required "annual verification" links to a copy of the UHC member login. Credentials give access to claims, prescriptions and personal details that make the next contact far more convincing.
4
Free equipment and testing schemes
A call offers a free brace, genetic test or DME item "covered by your plan", needing only your Medicare and member numbers. The item is billed to Medicare at a wildly inflated price, and the resulting record can block a genuinely needed item later.

Warning signs

An unsolicited caller needs your Medicare number or member ID before they will tell you anything
You are offered a grocery card, cash card or "flex card" for enrolling
The caller says your current plan is ending and you must act today
You are discouraged from hanging up and calling the number on the back of your card
A "nurse" or "care coordinator" you did not arrange asks for medical history and identifiers
Free medical equipment or a test is offered with no doctor involved
The email domain or link is not uhc.com, myuhc.com or your plan's stated site

Examples

The flex card that did not exist

A caller tells a 72-year-old that her UnitedHealthcare plan includes a $900 flex card for groceries and utilities, and confirms her Medicare number "to load it". No card arrives. Six weeks later, three durable-medical-equipment claims for braces she never received are billed against her Medicare number, and the annual limit for a brace she does need is already used up.

Switched without knowing

During open enrollment a man answers a few questions on what he thinks is a benefits review. In January his cardiologist is out of network. He was enrolled in a different plan on that call; the recording shows a rushed yes to a question he did not understand, and the enrollment window has closed.

What to do

Hang up and call the number on the back of your member card, or 1-800-MEDICARE for anything Medicare-related.
Never give your Medicare number, member ID or date of birth to a caller you did not dial.
Treat your Medicare number like a credit card number — it is the billing key to your benefits.
Check your Medicare Summary Notice and Explanation of Benefits for services and equipment you never received.
If you were switched without agreeing, call 1-800-MEDICARE immediately and ask about a Special Enrollment Period — there are grounds for one after a misleading enrollment.

Report it to UnitedHealthcare

Report fraud to UnitedHealthcare at 1-844-359-7736, and report Medicare-billing fraud to 1-800-MEDICARE or the Senior Medicare Patrol in your state.

Getting your money back

If a Medicare number has been given out, it cannot be changed the way a card number can, so the response is monitoring rather than replacement: read every Medicare Summary Notice, dispute anything you did not receive, and contact your state Senior Medicare Patrol, which exists specifically to help with this and is free. If you were enrolled in a plan without agreeing, 1-800-MEDICARE can open a complaint and may grant a Special Enrollment Period to undo it. If personal identifiers were also given up, file at IdentityTheft.gov.

Frequently asked questions

Does UnitedHealthcare call people about Medicare Advantage plans?

UnitedHealthcare and its contracted agents do make outbound calls, which is exactly what makes this hard — but Medicare rules bar them from cold-calling people who have not requested contact, and nobody legitimate needs your Medicare number to describe a plan. Hang up and call the number on your card or 1-800-MEDICARE.

Are the "flex cards" and grocery allowances advertised on TV real?

Some Medicare Advantage plans do include limited over-the-counter or grocery allowances, which is why the pitch works. The advertised amounts are almost always the maximum for a specific plan in a specific county, and a caller who offers one in exchange for your Medicare number is not enrolling you in it.

What can someone do with my Medicare number?

Bill Medicare for care and equipment you never received. That costs taxpayers, but it also costs you directly: fraudulent claims consume your benefit limits, and false entries end up in records your own doctors rely on. Report suspected misuse to 1-800-MEDICARE and your state Senior Medicare Patrol.
