Medicare Scam Alert: How to Protect Your Benefits During Enrollment Periods and Beyond

Why Medicare Scams Are a Growing Threat in 2026

Medicare fraud costs the federal government an estimated $60 billion or more per year, according to the Centers for Medicare & Medicaid Services. The people bearing the real cost are beneficiaries like you.

Scammers target Medicare beneficiaries for specific reasons. Fixed incomes create financial vulnerability, and enrollment periods create urgency. Fraudsters have become sophisticated enough to mimic CMS language, reference real plan changes, and make their calls nearly indistinguishable from legitimate outreach.

The FTC received over 2.6 million fraud reports in a recent year, with imposter scams among the top categories affecting older adults. This article provides a step-by-step guide to identifying, avoiding, and reporting Medicare fraud year-round, not just during open enrollment. The threat does not pause between October and December; it adapts.

The Most Common Medicare Scams Targeting Beneficiaries in 2026

Scam tactics evolve with the news cycle. In 2026, beneficiaries face a familiar but increasingly polished set of threats: fake plan-switching calls, Medicare identity theft via phone, genetic testing fraud, and COVID-related durable medical equipment schemes that haven't fully disappeared.

One of the more targeted tactics involves the 2026 Part B premium increase to $202.90 per month. Scammers impersonate CMS representatives, claiming beneficiaries owe a different amount and using that confusion to extract banking details or Medicare card numbers. Similarly, fake Medicare Advantage offers collect Social Security numbers under the guise of enrollment assistance.

Phone Scams and Fake Medicare Calls

Fake Medicare calls often display spoofed caller ID showing "1-800-MEDICARE." The script creates urgency, claiming your coverage is about to lapse, your card needs to be reissued, or there's been suspicious activity on your account. The goal is always the same: your Medicare Beneficiary Identifier (MBI) number.

Red flags to recognize immediately include:

• Unsolicited calls claiming to represent Medicare or CMS

• Requests for payment via gift card, wire transfer, or cryptocurrency

• Pressure to provide your Medicare or Social Security number to "keep your coverage active"

• A caller who becomes aggressive when you ask to call back through an official number

Medicare Genetic Testing Fraud

Genetic testing scams typically unfold at community events, health fairs, or via phone. Fraudsters offer a "free" cheek swab, collect your Medicare number, then bill Medicare for tests that were never ordered by your physician and may never have been performed at all.

Only agree to tests that your treating physician directly orders. Verify any genetic test charge on your Medicare Summary Notice each time it arrives.

How Medicare Identity Theft and Medicare Benefit Theft Actually Work

Once a scammer has your MBI number, they can bill Medicare for phantom services, equipment you never received, prescriptions never filled, or office visits that never occurred. This happens quietly, on paper, and often without a single interaction with you after the initial theft.

The danger compounds when your Social Security number is also exposed. Scammers who obtain both your SSN and MBI can open fraudulent financial accounts, file false tax returns, and apply for benefits in your name simultaneously. Treat both numbers with the same level of protection.

Suspicious billing practices you may never notice on your own include charges for tests you didn't take, equipment never delivered to your address, or provider names you don't recognize. Reviewing your Explanation of Benefits or MSN each time it arrives is your clearest window into Medicare benefit theft.

Warning Signs: How to Spot a Medicare Scam Before It's Too Late

Knowing the warning signs gives you a meaningful advantage. Most Medicare scams share a recognizable structure, even when the specific script changes.

Key red flags to watch for:

• Any unsolicited call, visit, or mailing claiming to be from Medicare asking for your MBI or SSN

• Offers of "free" equipment, tests, or benefits in exchange for your Medicare number

• Pressure to make an immediate decision "this offer expires today"

• A caller who already knows some of your personal details and uses them to build trust

• Plan offers that reference the 2026 premium changes as justification for urgency

To verify whether a Medicare plan offer is legitimate, check the plan's contract status at Medicare.gov, call 1-800-MEDICARE to confirm agent credentials, and never provide your MBI over the phone to someone who called you first. You can also review your full Medicare rights and protections to understand what legitimate outreach looks like.

How to Protect Your Medicare Benefits and Personal Information

Protecting yourself starts with a few consistent habits. Store your Medicare card securely and only share your MBI with your doctor, pharmacist, or a licensed insurance agent you contacted first. Never read your Medicare number aloud in public settings or provide it to any caller who reached out to you unsolicited.

During enrollment periods, be especially cautious of Medicare Advantage and Part D plan offers. Work only with licensed agents, verify plan details directly at Medicare.gov, and be skeptical of any mailer or call that references the 2026 premium changes as a reason to act immediately. For a structured review of what legitimate enrollment looks like, the Medicare enrollment checklist is a useful starting point.

Your SSN and Medicare number together create a complete fraud toolkit. Guard them with equal care; neither should be shared unless you initiated the interaction and have verified who you are speaking with.

How to Report Medicare Fraud to the Government: A Step-by-Step Guide

Reporting suspected fraud quickly limits the damage, both to your own Medicare record and to other beneficiaries who may be targeted by the same scheme. Here is where to go:

• 1-800-MEDICARE (1-800-633-4227): The primary line to report suspected fraud directly to CMS. Available 24 hours a day, 7 days a week.

• HHS OIG Hotline, 1-800-HHS-TIPS (1-800-447-8477): For formal fraud complaints investigated by the Office of Inspector General, which excluded over 1,600 individuals and entities from Medicare in a single year for fraud-related offenses.

• ReportFraud.ftc.gov: File a report with the FTC for broader tracking and consumer protection purposes.

• State SHIP Programs: Free, unbiased counseling available in every state to help you identify suspicious billing, understand your rights, and navigate the reporting process.

Before you call, gather the following: your Medicare number, the provider's name and address, the date of the billed service, and a clear description of why you believe the charge is fraudulent. Having this ready makes the process faster and more effective. You can also find additional detail on the formal Medicare claims process if you need to dispute a specific charge.

What to Do If You've Already Been Targeted by a Medicare Scam

If you believe your Medicare number has been compromised, call 1-800-MEDICARE immediately to report the incident and request a new Medicare card with a new MBI. If your Social Security number was also exposed, contact the three major credit bureaus (Equifax, Experian, and TransUnion) to place a fraud alert or credit freeze on your accounts.

To dispute fraudulent charges on your MSN or EOB, contact the listed provider in writing first. If the provider is unresponsive or the charge clearly reflects services never rendered, escalate directly to 1-800-MEDICARE or the HHS OIG hotline. Document every step of the process.
