Medicare Scams in California: How to Spot Them and Find an Agent You Can Trust

Why scam calls pick up every fall

Every year between October 15 and December 7 — Medicare’s Annual Enrollment Period — Californians on Medicare see a surge in calls, texts, mailers, and ads. Most are legitimate marketing. Some are not. Scammers know this is the one season when it’s normal to hear from insurance companies, and they use that cover to go after your Medicare number, your bank information, or an enrollment you never agreed to.

The good news: a few simple habits make you a very hard target, and California gives you strong, free tools to check exactly who you’re dealing with.

Red flags: how Medicare scams usually look

These patterns show up again and again in fraud reports:

• An unsolicited call “from Medicare.” Medicare does not call to sell plans, confirm your number, or offer new cards. Plan sellers are also not allowed to cold-call you about Medicare Advantage or Part D plans without your permission.
• Someone asks for your Medicare number to “verify” or “update” your file. Treat your Medicare number like a credit card number. Give it only to your doctors, pharmacy, insurer, or an agent who is actually enrolling you in a plan you chose.
• Free offers that need your Medicare number first. “Free” braces, back braces, genetic tests, or medical equipment offered by phone are classic schemes — the billing happens to Medicare, in your name.
• Pressure and urgency. “This price is only good today,” “your benefits will be cancelled,” “everyone in your area is switching.” Legitimate enrollment windows are set by federal rules, not by a caller’s deadline.
• A “helper” who wants to enroll you immediately on the first call. A real agent should be willing to compare options, put things in writing, and give you time to decide.
• Requests for payment by gift card, wire transfer, or payment app. No legitimate Medicare plan or agency collects premiums this way.

How to verify any agent or broker in California — in about two minutes

Anyone selling Medicare insurance plans in California must be licensed by the state. Checking is free and public:

1. Ask for their full name and license number. A legitimate agent will give both without hesitation. (Mine is CA License #4199527.)
2. Look them up with the California Department of Insurance at insurance.ca.gov (License Status Inquiry), or call CDI’s consumer hotline at 1-800-927-4357. You’ll see whether the license is active and what lines they’re licensed for.
3. Ask who they represent. Independent brokers work with multiple insurance companies; captive agents represent one. Neither is a scam — but you deserve a straight answer. Ask an independent broker how many organizations they represent. (I currently represent 12 organizations offering 442 products in this area — and I’m required to tell you that I do not offer every plan available in your area.)
4. Ask how they’re paid. Licensed agents and brokers are paid commissions by the insurance carriers, which is why their help costs you nothing. An honest agent will say this plainly.

What legitimate agents are — and aren’t — allowed to do

Federal marketing rules protect Medicare beneficiaries. A compliant agent:

• May not cold-call you about Medicare Advantage or Part D plans without your permission, show up at your door uninvited, or enroll you without your consent.
• May not claim to be “from Medicare,” use government logos to imply endorsement, or tell you a plan is “Medicare-approved” in a way that suggests the government recommends it.
• Must get your agreement (a “scope of appointment”) before discussing Medicare Advantage or Part D plans in a personal appointment.
• Should be willing to review your doctors, prescriptions, and priorities before recommending anything — whether that points to Medicare Advantage or a Medicare Supplement path.

If a caller breaks these rules, that alone tells you what you need to know.

If you think you’ve been targeted: report it

Reporting protects you and your neighbors, and it’s fast:

• 1-800-MEDICARE (1-800-633-4227) — report suspected fraud on your Medicare number or statements, 24/7.
• California Senior Medicare Patrol (SMP): 1-855-613-7080 — free, confidential help investigating suspected Medicare fraud, errors, and abuse. (The national SMP line is 1-877-808-2468.)
• California Department of Insurance: 1-800-927-4357 — complaints about an agent or insurance company.
• FTC: reportfraud.ftc.gov — identity theft and phone scams generally.

Also check your quarterly Medicare Summary Notice (or plan statements) for services you don’t recognize — that’s how much fraud gets caught.

A local note for Southern California

Los Angeles, Orange County, San Diego, and the Inland Empire are consistently among the busiest Medicare markets in the country, which means more marketing of every kind — including the bad kind. Two free, no-pressure resources worth knowing:

• HICAP — the Health Insurance Counseling and Advocacy Program, California’s State Health Insurance Assistance Program (SHIP), offers free, unbiased Medicare counseling at 1-800-434-0222.
• A licensed local broker you’ve verified — whether that’s me or anyone else, use the CDI lookup above first. If you’re new to Medicare and turning 65, verifying the person helping you is the single best first step.

Frequently asked questions

Does Medicare ever call you?

Not to sell plans or ask for your number. Medicare may call back if you contacted them first, and plans you’re already enrolled in may call about your existing coverage. An out-of-the-blue sales call “from Medicare” is not Medicare.

Is it safe to give my Medicare number to an agent?

Only when you’ve verified their license and you’re actually enrolling in a plan you chose. It’s never needed for a “quote,” a “verification,” or a free offer.

How do I check an insurance agent’s license in California?

Use the License Status Inquiry tool at insurance.ca.gov or call 1-800-927-4357. You need only the agent’s name or license number.

What’s a scope of appointment?

A federal requirement: before a personal Medicare Advantage or Part D sales appointment, you agree in advance (in writing or recorded) to what will be discussed. It exists to prevent surprise sales pitches.

Someone enrolled me in a plan I didn’t agree to. What now?

Call 1-800-MEDICARE right away. During certain windows, including the Annual Enrollment Period (October 15 – December 7) and, for Medicare Advantage members, the Medicare Advantage Open Enrollment Period (January 1 – March 31), you can also make a change. A Special Enrollment Period may apply for enrollments made without your consent.
