Medicare Open Enrollment 2026: Should You Change Your Medicare Plan for 2027?
Just because you can change your Medicare plan doesn't mean you should.
Every fall, Medicare beneficiaries begin hearing about new plans, changing benefits, different premiums, and opportunities to switch coverage.
And every year, the same question comes up.
Should I change my Medicare plan, or should I keep what I have?
It's a good question. And the answer isn't always as simple as choosing the plan with the lowest premium or the longest list of benefits.
I'm Sandra Reith, a licensed Medicare broker serving Green Valley, Sahuarita, Tucson, and Southern Arizona. I speak fluent Medicare, and one of the things I want people to understand is that choosing Medicare coverage isn't just about what works today.
It's also about understanding your options tomorrow.
With Medicare Open Enrollment beginning October 15, 2026, now is a good time to understand what you can change, what deserves a closer look, and when keeping your current coverage might be the better decision.
Watch: Can You Change Medicare Plans?
In this video, I explain some of the differences between changing Medicare Advantage plans and changing Medicare Supplement coverage.
The important thing to remember is that not all Medicare coverage changes follow the same rules.
Let's look at what that means for you.
When Is Medicare Open Enrollment in 2026?
Medicare's Annual Open Enrollment Period runs from October 15 through December 7, 2026.
During this time, eligible Medicare beneficiaries can review their coverage and make certain changes for the upcoming year.
Changes made during this enrollment period generally take effect January 1, 2027.
Depending on your current coverage, you may be able to switch from one Medicare Advantage plan to another, move between Original Medicare and Medicare Advantage, or change your Medicare Part D prescription drug plan.
You can also choose to keep your existing coverage.
In fact, sometimes that's exactly what makes sense.
The important thing is knowing whether your current plan will continue meeting your needs in 2027. Centers for Medicare & Medicaid Services
Why Should You Review Your Medicare Plan Every Year?
Here's something many people don't realize.
Even if you're happy with your Medicare coverage today, your plan may look different next year.
Medicare Advantage and Part D plans can change their premiums, deductibles, copayments, prescription drug coverage, provider networks, and other benefits from one year to the next.
That doesn't automatically mean your plan is getting worse.
It means you should understand what's changing.
Your Medicare Advantage or Part D plan generally sends an Annual Notice of Change explaining important updates to your coverage.
Don't set that letter aside without reading it.
It may contain information that affects your healthcare expenses or access to the services you use.
For example, imagine you've been seeing the same specialist for several years.
You like your doctor. You're comfortable with the office. Your appointments and treatments are working well.
Before deciding to keep or change your Medicare Advantage plan, wouldn't you want to know whether that specialist will still be in your plan's network next year?
Of course you would.
That's why reviewing Medicare coverage involves more than comparing monthly premiums.
Five Things to Review Before Changing Your Medicare Plan for 2027
1. Are your doctors and specialists still in your network?
For many Medicare beneficiaries, maintaining relationships with trusted healthcare providers is a priority.
If you have Medicare Advantage coverage, your plan may use a provider network.
That means the doctors, specialists, hospitals, and other healthcare providers you can use, and what you'll pay to see them, may depend on your particular plan.
If you live in Green Valley or Sahuarita, you may receive some of your healthcare locally and travel into Tucson for specialists or hospital services.
That's why checking your specific providers and facilities matters.
Don't assume that because your doctor accepted your insurance this year, the arrangement will be identical in 2027.
Verify the network before making a decision.
2. Will your prescription medications still be covered?
Prescription drug coverage deserves its own review.
Medicare Part D plans and Medicare Advantage plans that include prescription drug coverage maintain lists of covered medications called formularies.
Those formularies can change.
A medication covered under one cost-sharing tier this year may have different costs or coverage requirements next year.
You should also review whether your preferred pharmacy participates in the plan's network and whether another pharmacy might offer more favorable pricing.
For someone taking several medications regularly, these differences can be significant.
A plan with a lower monthly premium isn't necessarily the least expensive option once prescription costs are included.
3. What will your total healthcare expenses look like?
One of the biggest mistakes people can make when comparing Medicare plans is looking only at the monthly premium.
Your actual expenses may include premiums, deductibles, copayments, coinsurance, and other out-of-pocket costs.
A Medicare Advantage plan may offer a $0 monthly plan premium, but that doesn't mean all your healthcare services are free.
Most people must also continue paying their Medicare Part B premium.
Think about how you use healthcare.
Do you see specialists frequently? Do you have ongoing treatments? Are you expecting a procedure? Do you take several prescriptions?
Your answers can help determine which costs deserve the closest attention.
Medicare Advantage plans have annual limits on covered Part A and Part B out-of-pocket expenses. Those limits vary by plan and are another important part of comparing coverage.
The goal isn't simply to find the lowest advertised premium.
It's to understand what your coverage could realistically cost you.
4. Are you considering switching from Medicare Advantage to Original Medicare?
This is where I encourage people to be particularly careful.
Medicare Advantage and Original Medicare work differently.
Medicare Advantage plans are offered by private insurance companies approved by Medicare. They provide Medicare Part A and Part B benefits, usually through plan-specific rules and networks.
Original Medicare is the federal Medicare program.
People with Original Medicare may also choose to purchase Medicare Supplement Insurance, commonly called Medigap, to help pay certain out-of-pocket expenses.
However, here's something important.
Being allowed to leave a Medicare Advantage plan doesn't necessarily mean you're guaranteed to qualify for a Medicare Supplement policy.
Depending on your circumstances, you may need to answer medical underwriting questions when applying for Medigap coverage.
An insurance company may be permitted to charge more or deny an application outside certain protected enrollment periods.
There are exceptions, including specific guaranteed-issue rights and trial rights.
For example, some people who joined Medicare Advantage when first eligible for Medicare at 65 have special rights if they return to Original Medicare within their first year.
The rules depend on your circumstances.
This is one reason I encourage people to understand their options before canceling existing coverage. Medicare
5. Has anything changed in your life or health?
Sometimes the reason to review Medicare coverage has nothing to do with a new plan being advertised.
It has to do with your life.
Maybe you've developed a health condition that requires more frequent appointments.
Perhaps your doctor has recommended a new medication or treatment.
You might be planning to move, spend more time traveling, or change where you receive healthcare.
Your budget may have changed.
Or maybe you're perfectly happy with your coverage and simply want to make sure everything will continue working as expected.
All of those are good reasons to review your options.
Medicare coverage should support the way you actually live and receive healthcare.
Not just the way things looked when you originally enrolled.
Can You Change Medicare Advantage Plans Every Year?
Generally, yes.
During Medicare's Annual Open Enrollment Period, eligible beneficiaries can switch Medicare Advantage plans or make other permitted changes.
There is also a separate Medicare Advantage Open Enrollment Period from January 1 through March 31.
That second enrollment period is specifically for people already enrolled in Medicare Advantage.
During that period, eligible beneficiaries can make one change to another Medicare Advantage plan or return to Original Medicare, with the option to join a separate Medicare drug plan.
These enrollment periods have different rules, so understanding which one applies to you is important. Medicare
Can You Change Medicare Supplement Plans During Open Enrollment?
This is another common source of confusion.
Medicare's October 15–December 7 Open Enrollment Period is not the same as your individual six-month Medigap Open Enrollment Period.
Your Medigap Open Enrollment Period generally begins the first month you're 65 or older and enrolled in Medicare Part B.
During that protected period, you have important rights when purchasing Medicare Supplement coverage.
Outside that period, changing Medigap policies may involve medical underwriting unless you qualify for a guaranteed-issue right or another applicable protection.
This means someone who already has Medicare Supplement coverage should be especially thoughtful about replacing or canceling it.
Before making a change, understand whether you'll qualify for the replacement coverage and what it will cost. Medicare
What If You're Happy With Your Current Medicare Plan?
Then you may not need to change anything.
I think this is worth emphasizing because Medicare Open Enrollment can create a lot of noise.
There are advertisements, mailers, phone calls, and conversations about new benefits.
It's easy to start wondering whether you're missing something.
Sometimes you are.
Sometimes you're not.
If your current plan continues covering your medications, includes the healthcare providers you prefer, fits your budget, and meets your needs, keeping it may be a perfectly reasonable decision.
The purpose of reviewing your Medicare coverage isn't necessarily to find something new. It's to make sure what you have still works for you.
That's an important distinction.
Why Working With a Local Medicare Broker Can Help
Medicare rules apply nationwide, but healthcare decisions are often local.
The doctors you see, hospitals you use, pharmacies you visit, and Medicare Advantage plans available to you can depend on where you live.
Someone living in Green Valley may have different plan options and healthcare preferences than someone living in Phoenix or another Arizona community.
A local Medicare broker can help you review available plans and understand how their benefits and provider networks relate to your needs.
My approach begins with education.
I want you to understand your options, ask questions, and feel comfortable with the decisions you're making.
Sometimes that means exploring a different plan.
Sometimes it means discovering that your current coverage is already a good fit.
Either way, you deserve to understand why.
