Your Medicare Advantage Plan May Disappear in 2027—Here’s What to Do

Imagine opening your mail this fall and finding a letter that says the Medicare Advantage plan you carefully selected will not be available next year.

Your doctors may not have changed. Your prescriptions may be the same. Your health may even be the same.

But your Medicare plan may be changing around you.

Some insurance companies may increase copayments, reduce extra benefits, change provider networks, discontinue individual plans, or stop offering coverage in certain counties. That does not mean Medicare Advantage is disappearing, but it does mean beneficiaries should not assume that their current coverage will remain unchanged for 2027.

The lesson is simple: Never renew a Medicare plan on autopilot.

Why Medicare Advantage plans can change every year

A Medicare Advantage plan is offered under an annual contract between Medicare and a private insurance company. You then enroll in the plan offered by that company.

That arrangement gives the insurance company several choices each year. It may:

• Continue the plan with relatively few changes
• Redesign the plan
• Increase premiums or cost-sharing
• Reduce supplemental benefits
• Change its provider network
• Replace the plan with another plan
• Stop offering the plan in particular counties
• Terminate the plan entirely

In other words, enrolling in a Medicare Advantage plan is not like buying a house with a 30-year fixed mortgage. It is more like signing a lease that can be rewritten every January.

That is why Medicare beneficiaries must review their coverage every year—even when they are satisfied with the plan they have today.

Why are insurance companies making these changes?

There is no single reason. Medicare Advantage plans are being affected by several financial and regulatory pressures at the same time.

Higher use of medical services

Insurance companies refer to this as “medical utilization.”

When plan members use more hospital care, outpatient procedures, diagnostic tests, physician services, rehabilitation, and other medical treatment than expected, the plan’s expenses increase.

Hospital and medical costs have also risen. A plan that appeared financially sustainable when it was designed may become less attractive to the insurance company when claims are higher than projected.

The insurance company then has to decide how much of that higher cost it can absorb and how much must be reflected in next year’s plan.

Changes to Medicare payments

Medicare Advantage companies receive payments from the federal government to provide Medicare-covered services to their members.

Those payments are affected by several calculations, including the health risk of the people enrolled in the plan. CMS completed a multiyear transition to an updated Medicare Advantage risk-adjustment model for 2026.

For 2027, CMS finalized payment policies expected to produce an average increase in Medicare Advantage payments. However, a national average does not tell us what will happen to every company, contract, plan, or county. One insurer may expand in one area while reducing its presence somewhere else.

The 2027 Medicare Advantage Rate Announcement explains the national payment changes, but it cannot tell an individual beneficiary whether a particular plan will remain available.

Changes to Star Ratings and bonus payments

Medicare uses Star Ratings to measure plan quality and help beneficiaries compare their choices.

Those ratings are not merely decorative gold stars on a government website. They can affect the bonus payments and rebate dollars insurance companies receive.

When a plan’s rating or bonus payment changes, the company may have less money available for lower copayments or supplemental benefits. CMS has also finalized additional Medicare Advantage and Part D Star Ratings changes for 2027.

Prescription-drug expenses

The Medicare Part D benefit has been redesigned to give beneficiaries greater protection from catastrophic prescription costs.

That protection is important, but the cost of expensive medications did not simply disappear. The redesign changed how prescription expenses are divided among beneficiaries, Medicare, drug manufacturers, and insurance companies.

As plans assume a different share of certain drug costs, they may respond through premiums, formularies, pharmacy arrangements, utilization-management requirements, or broader plan changes.

What can an insurance company do when costs rise?

When a Medicare Advantage plan becomes less profitable, the company generally has three broad choices.

1. Increase premiums or cost-sharing

A plan may increase its monthly premium, although many Medicare Advantage plans continue to advertise a zero-dollar plan premium.

The company may instead raise:

• Specialist copayments
• Hospital copayments
• Outpatient surgery costs
• Diagnostic imaging costs
• Ambulance copayments
• Skilled nursing costs
• Coinsurance for durable medical equipment
• The annual maximum out-of-pocket limit

This is why “zero-dollar premium” does not mean zero healthcare costs. Premium is only one part of the equation.

Our article, New Medicare Rules That Could Affect Your Costs and Coverage, explains why beneficiaries must look beyond the monthly premium.

2. Reduce benefits or provider networks

The plan may reduce dental, vision, hearing, transportation, food, fitness, or over-the-counter benefits.

It may also make changes to its provider network.

A dental allowance may be useful. A grocery card may help. But neither one will replace your cardiologist, oncologist, hospital, or treatment center.

Provider participation must be checked using the exact plan—not merely the insurance company’s name. An insurance company can offer several plans in the same county, and a doctor may participate with one but not another.

Read Can I Use My Current Doctor With Medicare Advantage? for the questions you should ask before assuming your doctor is covered.

3. Discontinue the plan or leave the county

If the company determines that a plan or county is no longer financially sustainable, it may stop offering that plan in the area.

This does not necessarily mean the insurance company is abandoning Medicare Advantage nationwide. A company may continue operating in profitable counties while withdrawing from areas where enrollment, provider contracts, competition, or medical expenses do not support the plan.

That distinction matters. National Medicare Advantage enrollment can remain strong while an individual beneficiary still loses the exact plan that worked for them.

The letter you should never ignore

Every fall, your Medicare Advantage or Part D plan sends an Annual Notice of Change, commonly called the ANOC.

According to Medicare.gov, the ANOC describes changes in plan coverage, costs, and other provisions that will take effect in January.

This is not another advertisement.

Your ANOC is the plan telling you, in writing, what will be different next year.

When it arrives, check:

• The monthly premium
• Medical deductible, if any
• Primary-care and specialist copayments
• Hospital and outpatient costs
• Maximum out-of-pocket limit
• Prescription-drug deductible
• Drug formulary and tiers
• Prior-authorization requirements
• Pharmacy network
• Dental, vision, and hearing benefits
• Provider network or service-area changes

Do not merely look at the first page and decide that everything appears familiar. The plan may retain the same name while changing important costs and benefits underneath it.

Four problems Medicare Advantage members should examine

The provider problem

A Medicare Advantage plan can become a poor choice if your doctors, hospital, rehabilitation facility, or treatment center is not in its network.

Call both the plan and the provider. Ask:

“Will this doctor be participating in this exact plan in 2027?”

Do not settle for “We accept Medicare.” That answer could refer to Original Medicare rather than your Medicare Advantage plan.

The prescription problem

Check every medication—not only your most expensive prescription.

Confirm the exact drug, dosage, quantity, pharmacy, tier, and restrictions. A drug may remain on the formulary but move to a more expensive tier. It may acquire prior authorization, step therapy, or a quantity limit.

A low-premium plan can become an expensive plan if its prescription coverage does not match your medications.

The treatment-continuity problem

Someone receiving cancer treatment, dialysis, cardiac care, rehabilitation, or another continuing course of care has more at stake than someone who sees a doctor twice a year.

A plan change can affect treatment facilities, specialists, referrals, prior authorizations, and approved services. People receiving continuing treatment should contact their medical providers and the new plan before coverage changes.

The total-cost problem

Do not compare plans by premium alone.

Calculate what could happen during an expensive healthcare year. Examine hospital copayments, outpatient procedures, specialist visits, diagnostic tests, Part B medications, and the maximum out-of-pocket limit.

The maximum out-of-pocket limit generally applies to covered Part A and Part B services. Prescription expenses and plan premiums are handled separately.

Medicare is a financial decision as well as a medical decision. The question is not simply, “Which plan is cheapest today?” The better question is, “Which financial risk can I realistically afford?”

What happens if your plan is discontinued?

First, do not panic. But do not delay.

Read the termination notice carefully. Determine whether:

• Your particular plan is being discontinued
• The plan is being replaced
• The insurance company is leaving your county
• The company’s Medicare contract is ending
• Your provider is leaving the network while the plan continues

If your plan ends, you may qualify for a Special Enrollment Period that allows you to select another Medicare Advantage plan or return to Original Medicare and obtain separate Part D coverage.

You may also qualify for guaranteed-issue rights to purchase certain Medigap policies. Under guaranteed-issue protection, an insurance company generally cannot deny the eligible policy or charge more because of your health.

Medicare says that qualifying beneficiaries may apply for Medigap beginning 60 days before their Medicare Advantage coverage ends and no later than 63 days afterward. Keep every letter and notice from the plan because you may need proof that your coverage ended. Review the official Medicare guidance on when you can purchase Medigap.

State laws may provide additional protections. The exact circumstances matter, so do not assume every benefit change automatically creates the same Medigap rights.

Should you choose another Medicare Advantage plan or Medigap?

This is where the discussion must remain balanced.

Medicare Advantage may provide:

• Lower monthly premiums
• An annual medical maximum out-of-pocket limit
• Prescription coverage within many plans
• Dental, vision, hearing, and other supplemental benefits
• Coordinated care

However, members may face networks, copayments, prior authorization, and yearly plan changes.

Original Medicare combined with Medigap may provide broader access to providers who accept Medicare and more predictable medical expenses.

However, it usually requires a separate Medigap premium and a separate Part D plan. Those premiums continue every month whether you use healthcare or not, and Medigap premiums can rise over time.

For a husband and wife, the premium must be calculated twice.

One person may prefer to pay more every month for greater predictability. Another may prefer lower premiums while accepting the possibility of higher costs when care is needed.

That is the real choice: Pay more now just in case, or potentially pay more later if you need care.

Our complete comparison, Medicare Advantage vs. Medigap: Which Is Better for Seniors?, explains the advantages and financial risks of both paths.

Do not decide based on perks alone

Extra benefits can be valuable, but they should never come before the fundamentals.

Before selecting a plan, ask:

1. Are my doctors and hospitals in the network?
2. Are all my prescriptions covered affordably?
3. What will I pay if I am hospitalized?
4. What services require prior authorization?
5. What is my total maximum financial exposure?
6. Can I afford the plan during both healthy and unhealthy years?
7. Am I comfortable reviewing this coverage again next year?

A grocery card is not a provider network. A dental allowance is not hospital coverage. A zero-dollar premium is not free healthcare.

The complete 2027 picture is not yet public

As of September 1, 2026, the final nationwide 2027 Medicare Advantage and Part D landscape has not been publicly released.

CMS says it expects to publish finalized plan offerings, average premiums, and other 2027 landscape information in mid-to-late September. Until that information is released, claims about exactly how many plans or counties will be affected should be treated cautiously. You can review the CMS announcement and expected release schedule here.

There will undoubtedly be changes. But we should not turn preliminary information or private plan data into nationwide predictions before the public numbers are available.

The facts will be important enough. They will not need exaggeration.

The bottom line

Your Medicare Advantage plan may remain available in 2027—but it may not remain the same plan.

The premium could change. Copayments could rise. Benefits could shrink. A prescription could move to another tier. A doctor could leave the network. The plan could be discontinued or withdrawn from your county.

That does not mean Medicare Advantage is automatically the wrong choice. It means last year’s decision should not automatically become next year’s decision.

Read your ANOC. Check your doctors. Enter every prescription. Compare the maximum out-of-pocket risk. Examine both Medicare Advantage and Original Medicare with Medigap.

Most importantly, compare the healthcare—not merely the advertising.
