Leaving Medicare Advantage? Read This Before You Cancel

Dropping Medicare Advantage is easy, but getting a Medigap plan afterward may not be.

Every fall I talk to people who are done with their Advantage plan. Maybe a doctor left the network. Maybe a prior authorization got denied. Maybe they just want to see any doctor who takes Medicare. All of that is fair. But the first thing I ask is not “which plan do you want?” It is “have you been approved for a Medigap plan yet?” Most of the time, the answer is no. And that is where the trouble starts.

A lot of people on Medicare Advantage assume they can switch back to Original Medicare and pick up a supplement any time they want. For many, that is not true. Outside of a few protected windows, a Medigap company can ask health questions and turn you down. So the people who most want to leave their Advantage plan are often the ones who can’t get a supplement to go with it. I see this in real life, and I want to explain what it means for you before you make a move.

Here is why this matters to you. Maybe you have health problems. Maybe you just take a few prescriptions and see a couple of specialists. Either way, the rules for getting a Medigap plan after your first window may not work in your favor. You can leave Advantage with one phone call. Getting into Medigap can be a different story. If you cancel first and ask questions later, you could end up with Original Medicare and no supplement at all. That means you pay your share of costs with no help and no yearly cap on what you spend.

So let’s look at whether you can move from an Advantage plan to Medigap when your health is not perfect. We will walk through it the way we would at your kitchen table.

If you have health problems, can you still get a Medigap plan?

You can apply, but in many cases the insurance company can ask health questions and turn you down. That is the short answer, and it surprises a lot of people.

When you first get Part B, you have a one-time Medigap Open Enrollment Period. It lasts 6 months. During that window, a Medigap company cannot refuse to sell you a plan or charge you more because of your health. After that window closes, things change. In most states, the company can ask about your medical history. This is called medical underwriting.

Underwriting questions often ask about things like:

Recent hospital stays or surgeries
Heart conditions, cancer, or COPD
Diabetes with complications
Planned treatments or tests you have not had yet
Certain medications you take

Based on your answers, the company can approve you, charge you more, or say no. Each company has its own rules, so a “no” from one does not always mean a “no” from all of them. But you should go in expecting that your health matters.

Are there times when they have to accept you no matter what?

Yes. There are a few situations called guaranteed issue rights. If you have one, a Medigap company must sell you certain plans no matter your health. The trick is knowing whether you qualify and acting inside the time limit.

Some common examples include:

The trial right. Say you joined an Advantage plan when you first got Medicare at 65, and you are still in your first 12 months. You can usually go back to Original Medicare and buy a Medigap plan without health questions.
You dropped Medigap to try Advantage. If this was your first time in an Advantage plan and you are within 12 months, you can often get your old Medigap back. If it is not available, you can often get a similar one.
Your plan is leaving. If your Advantage plan stops serving your area or leaves the program, you may get a guaranteed right to buy Medigap.
You move out of the plan’s service area. That can also trigger a right.

On top of the federal rules, some states have their own extra protections. A few states let people switch Medigap plans or buy one with fewer health questions at certain times of year. The rules differ a lot from state to state. So this is something we check for each person, not something you should assume.

If none of these apply to you, you are likely in underwriting territory. That is not a reason to panic. It is a reason to plan.

What order should you do things in?

Apply for Medigap first, get approved, and only then leave your Advantage plan. This one step prevents most of the problems we see.

Here is the order we walk people through:

Check for any guaranteed issue rights. If you have one, the path is much simpler.
If not, apply for Medigap while you are still in your Advantage plan. You do not have to leave Advantage to apply. You just set the start date to match when your Original Medicare coverage kicks back in.
Wait for the approval in writing. Do not cancel anything based on a phone call or a “you should be fine.”
Pick a stand-alone Part D drug plan. Most Advantage plans include drug coverage. When you leave, that goes away. Going without creditable drug coverage can lead to a late enrollment penalty that stays with you.
Make the switch during the right enrollment period. The Annual Enrollment Period runs October 15 to December 7, with changes starting January 1. The Medicare Advantage Open Enrollment Period runs January 1 to March 31. It also lets you go back to Original Medicare and add a drug plan.

Joining a stand-alone drug plan usually moves you out of your Advantage plan automatically. That is why the Medigap approval has to come first. Once the drug plan starts, the Advantage coverage ends, whether your supplement is ready or not.

If the enrollment windows feel confusing, our page on Medicare enrollment periods lays them out in plain terms.

What happens if you get turned down for Medigap?

If you are denied, you can usually stay in your Advantage plan or pick a different one, so you do not have to go without coverage. That is exactly why the order matters. When you apply first, a “no” just means you stay put and look at other options.

Some of those options may include:

Trying another Medigap company with different underwriting rules
Choosing a different Advantage plan with a network that fits your doctors better
Seeing whether you qualify for a Special Needs Plan if you have certain chronic conditions
Waiting until a guaranteed issue right applies, if one is coming

What we never want is for someone to cancel first, get denied second, and end up on Original Medicare alone. Original Medicare by itself covers a lot. But without a supplement, you pay the Part A deductible, which is $1,736 in 2026, for each benefit period in the hospital. You also pay the Part B deductible, $283 in 2026, and then generally 20% of approved costs after that. There is no yearly limit on that 20%. For someone with ongoing health needs, that can add up.

Is staying in Medicare Advantage ever the right call?

Yes, and we would be doing you a disservice if we did not say so. For some people with health problems, staying in a well-chosen Advantage plan makes more sense than chasing a Medigap plan they may not get.

Here are the honest tradeoffs as we see them:

Advantage plans have a yearly out-of-pocket limit. Original Medicare alone does not. If you cannot get Medigap, that limit is real protection.
Medigap usually has a monthly premium. You also pay the Part B premium, which is $202.90 in 2026, plus a Part D premium. Some Advantage plans have a $0 premium. That does not mean the coverage costs nothing, because you still pay the Part B premium and your copays. But the monthly budget can look very different.
Medigap gives you more freedom. You can see any provider in the country who accepts Medicare, with no network and generally no prior authorization from the plan.
Advantage plans often have networks and prior authorization rules. If those have caused you real problems, that matters.

Here is the part that may cost us your business. If you have serious health issues and no guaranteed issue right, Medigap may not be available to you right now. In that case, the smarter move might be finding a better Advantage plan, not leaving Advantage altogether. We would rather tell you that today than watch you lose coverage in January.

If you want to compare the two side by side, our Medicare Supplement help page covers how Medigap plans work in more detail.

How do you know where you stand right now?

The fastest way is to look honestly at your current plan, your health, and your rights before the enrollment window closes. Most people have never done that review. They just renew and hope.

That is why we built a short tool to help. It asks a few simple questions about your plan and your situation, then points out where you might have blind spots. It does not ask you to buy anything. Find out in 3 minutes if your plan has hidden risks.

If you would rather talk it through with a person, you can call Scott at 512-844-3983. You will reach Scott or someone on our team, not a call center reading a script. We work with people in multiple states, and we will tell you plainly if staying where you are is the smarter choice.

The bottom line: you can leave Medicare Advantage when an enrollment window allows. Just do not leave until you know where you are landing.
