Can an Agent Sell Medigap If You Have Medicare Advantage?

If you're on a Medicare Advantage plan and an agent is pitching you a Medigap policy, that sale is almost always illegal. Federal law bars an agent from knowingly selling Medigap to someone enrolled in Advantage, and it spells out exactly when the sale is banned and what it costs the person who breaks the rule. If something about the pitch feels off, trust that instinct.

Can an Agent Sell You Medigap If You Have Medicare Advantage?

The short answer is no. If you're enrolled in a Medicare Advantage plan, it is illegal for an agent to knowingly sell you a Medigap policy. This isn't a gray area or a matter of company policy. It's spelled out in the Centers for Medicare & Medicaid Services guide to choosing a Medigap policy, which lists selling to someone in a Medicare Advantage plan among the practices that are outright illegal.1

There's a reason the sale is banned. Medigap is built to work alongside Original Medicare, filling in the Part A and Part B costs it leaves you to pay. It doesn't pair with a Medicare Advantage plan. So an agent who sells you one while you're on Advantage is selling you coverage you can't actually put to work, which is exactly what the rule exists to stop.

If an agent knows you're in an Advantage plan and pushes a Medigap policy anyway, that's your signal to stop the conversation and check the exception below before you sign anything.

When It Is Legal to Sell Medigap to a Medicare Advantage Member

There's one situation where the sale is allowed: you're switching back to Original Medicare. If your Medicare Advantage coverage is ending before the Medigap policy takes effect, an agent can legally sell you a Medigap policy to have in place when you land back on Original Medicare.1

That's a real and common move. People leave Advantage plans during the fall Open Enrollment Period or the Medicare Advantage Open Enrollment Period every year, and lining up a Medigap policy so there's no gap when Original Medicare restarts is legitimate. The line the law draws is about timing and intent: it's fine to buy Medigap because you're on your way back to Original Medicare, and it's illegal to be sold one while you're staying put in an Advantage plan.

If an agent tells you the exception applies, make sure it actually does. You should have a real plan to disenroll from Advantage, with your Medigap start date built around that switch. If you have no intention of leaving your Advantage plan, the exception doesn't cover the sale. (Weighing the switch itself? Our guide to Original Medicare versus Medicare Advantage walks through the trade-offs.)

The Two Other Sales the Law Bans

The Medicare Advantage rule is the one most people ask about, but the same law blocks two other Medigap sales.1

A second Medigap policy, with no plan to drop the first. It's illegal for an agent to sell you a Medigap policy when they know you already have one. There's one way around it: you can buy a new policy if you state, in writing, that you plan to cancel your existing one. No written cancellation statement, no legal sale. That rule exists because paying two Medigap premiums for overlapping coverage helps nobody but the agent's commission.

A policy sold to someone on Medicaid. With limited exceptions, it's illegal to sell a Medigap policy to a person who has Medicaid. Medicaid already covers most of the cost-sharing a Medigap policy would, so selling one to a Medicaid enrollee usually means selling duplicate coverage they don't need.

What It Costs an Agent Who Breaks the Rule

These aren't soft consumer-protection guidelines. The penalties live in the Social Security Act, at section 1882(d)(3)(A), and they have teeth.1

An agent who commits one of these prohibited acts can be fined under the federal criminal code, imprisoned for up to 5 years, or both. On top of that, or instead of it, they face a civil money penalty of up to $25,000 for each prohibited act. If the seller isn't the insurance company that issued the policy, the civil penalty is capped at $15,000 per act instead.1

The phrase "each prohibited act" matters. The penalty isn't one flat fine for a bad habit. It attaches to every improper sale, so an agent working the same pitch across a room of Medicare Advantage members is stacking exposure with each signature.

How to Spot and Report a Bad Pitch

You don't need to memorize the statute to protect yourself. The CMS Medigap guide names the moves that cross the line, and they're easy to recognize once you know them. According to that guide, it's illegal for someone to pressure you into buying a Medigap policy, or to lie to get you to switch to a new company or policy.1 Add the three prohibited sales above, and you've got a short checklist of red flags:

• An agent pushes Medigap even after you say you're staying in your Medicare Advantage plan.
• You already have a Medigap policy and the agent never asks you to cancel it in writing.
• You're on Medicaid and the agent skips right past that.
• You feel rushed, cornered, or told half-truths to get you to switch.

If any of that happens, you have somewhere to go. Report the agent to your state's insurance department, which licenses and disciplines insurance agents in your state, and to Medicare directly. Write down the agent's name, the company, and what was said while it's fresh. You don't have to prove the law was broken to file a complaint. That's the regulator's job once you flag it.
