Medicare Scam Calls: How to Spot and Stop Them

Medicare scam calls impersonate representatives from the Centers for Medicare & Medicaid Services (CMS), Medicare supplement insurance providers, or the Social Security Administration to extract Medicare Beneficiary Identification numbers, Social Security numbers, bank account details, and credit card information. According to the FTC's FY2025 data, medical and prescription schemes were among the top five complaint categories, with seniors over 70 reporting a median fraud loss of $1,450 per incident — the highest of any age group.

What Medicare Scam Callers Actually Say

Medicare scammers use a consistent set of scripts designed to create urgency and authority. The most common approaches:

• "Your Medicare card is expiring and needs to be replaced." Medicare cards do not expire. The red, white, and blue card you received has no expiration date. Anyone claiming your card needs renewal is not calling from Medicare.
• "You're owed a refund / rebate check from Medicare." Medicare does not proactively call beneficiaries to offer refunds. If you are owed a refund, it arrives via mail or is automatically applied to your account — you are never asked for bank information to receive it.
• "We need to verify your Medicare number to process your free equipment." Medicare does not cold-call beneficiaries to offer free equipment. All durable medical equipment under Medicare requires a physician's order and pre-authorization — it is never initiated by an outbound Medicare phone call.
• "There's a problem with your Medicare account that requires immediate action." Urgency framing is a standard manipulation tactic. Medicare does not call beneficiaries about account problems requiring immediate phone resolution. All legitimate Medicare communications about account issues arrive in writing.
• "Press 1 to speak to a Medicare specialist." This is an automated robocall triggering a live scammer when you engage. The moment you press 1, your number is confirmed as active and engaged, escalating your position on their target list.

What Information They're Actually Trying to Steal

The ultimate targets in a Medicare scam call are layered:

• Medicare Beneficiary Identifier (MBI): Your 11-character Medicare ID number, which replaced Social Security numbers on Medicare cards in 2018. This number is used to bill Medicare fraudulently — charging for medical services never rendered under your identity.
• Social Security Number: Used for identity theft extending far beyond Medicare — tax fraud, new account fraud, credit applications.
• Bank account or routing numbers: Requested under the guise of "direct depositing your refund" or "setting up auto-pay for your supplement."
• Supplemental insurance information: Used to cross-reference and escalate fraud across multiple insurance billing systems.

How to Verify If a Medicare Call Is Legitimate

Medicare (1-800-MEDICARE / 1-800-633-4227) does occasionally call beneficiaries, but only:

• If you recently filed a complaint or inquiry with Medicare and a representative is following up
• If you are enrolled in a Medicare plan that has specifically authorized outbound care coordination calls
• In the context of a Medicare study or survey — which you will have been informed of in writing first

In all other cases: hang up and call 1-800-MEDICARE directly using the number you look up yourself — not a number the caller provides. Any legitimate Medicare issue can be verified through that channel. Never give your Medicare number, Social Security number, or financial information to an incoming caller who claims to represent Medicare.

How do you report Medicare scam calls?

Report Medicare scam calls to multiple agencies simultaneously:

• HHS Office of Inspector General: 1-800-HHS-TIPS (1-800-447-8477) or online at oig.hhs.gov — handles Medicare fraud directly
• FTC: ReportFraud.ftc.gov — feeds the Consumer Sentinel Network used by law enforcement
• Your state's Senior Medicare Patrol: A federally funded program in every state that helps seniors identify and report Medicare fraud. Find yours at smpresource.org

How to Stop Medicare Scam Calls From Reaching Your Phone

The Do Not Call Registry does not stop Medicare scam calls — these callers are criminals who do not check the Registry. The effective layer of protection is at the phone itself: an app using Android's native ROLE_CALL_SCREENING API to intercept calls before the phone rings and classify them using behavioral pattern analysis. Callro's Gauntlet Engine identifies Medicare and government impersonation robocall campaigns through call frequency patterns and number structure analysis. Callro rejects the call before it reaches your phone, using Intelligent Network Rejection (INRS) — no audio tone is generated or played. There is no scam script if there is no call.
