How to Switch, Step by Step

Switching Steps

1

Read your Annual Notice of Change. Decide whether your current plan still fits for 2027.

2

List your doctors, drugs and pharmacies. You will check each against new plans.

3

Compare plans on Medicare Plan Finder. Look at networks, drug costs and the out-of-pocket maximum.

4

Enroll in the new plan. Use Medicare.gov, 1-800-MEDICARE or the plan itself.

5

Watch for confirmation. You should get a confirmation and a new member card.

6

Do not cancel your old plan separately. Joining the new plan ends the old one automatically.

Switching to Another Plan vs Original Medicare

To Another Medicare Advantage Plan

✔

Enrollment in the new plan ends the old one

✔

Drug coverage usually comes with the plan

✔

Check the new network carefully

Back to Original Medicare

✔

Join a Part D plan to keep drug coverage

✔

Consider Medigap, but health questions may apply

✔

Any provider that accepts Medicare

Guaranteed issue: if your Medicare Advantage plan leaves your area, you generally can buy certain Medicare Supplement plans without health questions, until 63 days after your coverage ends.

Mistakes to Avoid When Switching

Avoid These

✔

Canceling your current plan before the new one starts

✔

Leaving Medicare Advantage without joining a Part D plan

✔

Assuming your doctors are in the new network

✔

Comparing premiums only, not total yearly cost

✔

Missing the December 7 deadline

If Your Plan Is Ending

If your plan will not be offered in your county for 2027, you should have received a non-renewal notice in early October. Your coverage does not stop right away: it continues through December 31, 2026, so you have time to choose.

If Your Plan Is Ending

1

Read the non-renewal letter. It confirms your plan is ending and explains your options.

2

List your doctors and drugs. You will need them to compare replacement plans.

3

Compare plans for 2027. Check networks, drug coverage and the out-of-pocket maximum, not just the premium.

4

Choose by December 31 for no gap. Enrolling during Annual Enrollment by December 7 gives you coverage on January 1, 2027.

5

Use your Special Enrollment Period if needed. People whose plans end generally can still make a choice through the end of February 2027.

If you do nothing: you return to Original Medicare on January 1, 2027, without drug coverage unless you choose a Part D plan. Going without drug coverage can lead to a late enrollment penalty.

Medigap rights: when your Medicare Advantage plan leaves your area, you generally have a guaranteed issue right to buy certain Medicare Supplement plans without health questions, up to 63 days after your coverage ends.

Staying Informed about Medicare Changes

Enrollment Periods

Enrollment Period Dates What You Can Do
Annual Enrollment Period October 15 to December 7, 2026 Join, switch or drop a Medicare Advantage or Part D plan for January 1, 2027
Medicare Advantage Open Enrollment January 1 to March 31, 2027 If you are in Medicare Advantage, switch to another plan or return to Original Medicare once
Initial Enrollment Period 7 months around your 65th birthday month Sign up for Medicare and choose your first plan
Special Enrollment Periods Varies Change plans after events like moving, losing other coverage or your plan leaving your area

Most people make changes during Annual Enrollment. If you are happy with your current plan, you do not have to do anything; it renews automatically. Still, read your Annual Notice of Change, because premiums, copays, networks and drug lists can all change on January 1.

Star Ratings

Medicare rates every Medicare Advantage and Part D plan from 1 to 5 stars each fall, based on things like preventive care, how well the plan manages chronic conditions, member complaints, customer service and drug pricing accuracy. The ratings are shown in Medicare Plan Finder.

Using Star Ratings

✔

A rating of 4 stars or higher is generally a good sign of quality and service

✔

Five-star plans have a special enrollment period, so you can switch into one once during the year

✔

New plans may not have a rating yet, which is not a bad sign by itself

✔

Ratings measure the plan overall, not how well it covers your specific doctors and drugs

Reading Your Annual Notice of Change

Check Every Line

✔

Your 2027 premium and deductible

✔

Copays for doctors, specialists and hospital stays

✔

The out-of-pocket maximum

✔

Updates to your formulary, drug tiers and coverage requirements

✔

Whether your doctors, hospitals and pharmacy are still in network

✔

Changes to dental, vision, hearing and other extras

Plans must send the Annual Notice of Change by September 30. It is the single most useful document you get each fall, because it tells you exactly how your plan changes on January 1.

Special Enrollment Periods

Outside the fall and early-year windows, you generally need a Special Enrollment Period to change plans. Common reasons include:

You May Qualify If

✔

Your plan is leaving your area or ending

✔

You move outside your plan’s service area

✔

You lose employer or union coverage

✔

You qualify for Extra Help or a Medicare Savings Program, or your Medicaid status changes

✔

You want to join a 5-star plan, once a year

Each Special Enrollment Period has its own time limit, so act as soon as the event happens.

Prior Authorization and Referrals

Most Medicare Advantage plans require prior authorization for some services, such as certain surgeries, advanced imaging, skilled nursing stays and some drugs. Your doctor usually requests it, but ask whether a planned service needs approval so a denial does not surprise you.

If a request is denied, you or your doctor can appeal. Medicare rules set deadlines for plans to decide, with faster deadlines when waiting could seriously harm your health.

Emergency, Urgent and Out-of-Area Care

Every Medicare Advantage plan covers emergency care and urgent care anywhere in the U.S., in or out of network, and you do not need prior approval for an emergency. Routine care away from home is a different story: HMOs generally do not cover it, while PPOs cover out-of-network care at a higher cost.

If you spend months away from home each year, ask each plan how it handles care in your second location. It is one of the most common reasons people switch plans mid-year.

Appeals and Complaints

If your plan denies a service, a drug or payment for care, you have the right to appeal. The plan’s denial notice explains how. There are several levels of appeal, starting with the plan and moving to independent reviewers.

For problems that are not about coverage, such as customer service or wait times, you can file a grievance with the plan. You can also contact 1-800-MEDICARE or your State Health Insurance Assistance Program for help.

The 2027 Part B Premium

The Part B premium is the one big number not released with the plans. CMS normally announces it in November. The 2026 Medicare Trustees Report projects a 2027 standard premium of about $209.50 a month and a deductible of about $292, up from $202.90 and $283 in 2026. You keep paying it with Medicare Advantage.

If You Miss December 7

If you miss the Annual Enrollment deadline, your current plan renews automatically for 2027, with the changes in your Annual Notice of Change. If you are in Medicare Advantage, you get one more chance from January 1 to March 31, 2027, to switch Medicare Advantage plans or return to Original Medicare and join a Part D plan.

Telehealth

Many Medicare Advantage plans may cover telehealth visits for some services, sometimes at a lower copay than an office visit. Telehealth is convenient for follow-ups and minor issues, but it does not replace confirming that your regular doctors are in network.

Pros and Cons of Medicare Advantage

Advantages

✔

Often a low or $0 premium

✔

A yearly out-of-pocket maximum

✔

Drug coverage usually included

✔

Many plans may include dental, vision and hearing benefits

✔

One card and one plan

Tradeoffs

✔

Networks; HMOs require in-network care except emergencies

✔

Prior authorization and referrals are common

✔

Copays add up if you use a lot of care

✔

Plans and networks can change every year

✔

Switching to Medigap later may require health questions

Special Needs Plans

Special Needs Plans (SNPs) are Medicare Advantage plans built for specific groups. Benefits, networks and drug lists are designed around the members they serve, and many include care coordinators. For 2027, Special Needs Plans are one of the few areas where large insurers are adding plans, even as they cut PPOs.

Type Who Qualifies What Is Different
Dual Special Needs Plan (D-SNP) People with both Medicare and Medicaid Coordinates both programs; often very low costs and added benefits
Chronic Condition SNP (C-SNP) People with qualifying conditions such as diabetes, heart failure or chronic lung disease Doctors, drugs and programs built around the condition
Institutional SNP (I-SNP) People living in a nursing home or who need that level of care at home Care delivered where the member lives

Turning 65 in 2027

If you turn 65 in 2027, your Initial Enrollment Period lasts seven months: the three months before your birthday month, your birthday month and the three months after. Signing up during the first three months means your coverage starts on the first day of your birthday month.

Turning 65 Checklist

✔

Sign up for Part A and Part B, unless you have qualifying employer coverage and choose to delay Part B

✔

Decide between Medicare Advantage and Original Medicare with Medigap

✔

Join a drug plan, or a Medicare Advantage plan with drugs, to avoid a Part D late penalty

✔

If you choose Medigap, buy during your six-month Medigap Open Enrollment Period

Frequently Asked Questions

➤ How do I switch Medicare Advantage plans for 2027?

Compare plans and enroll in the new one during Annual Enrollment, October 15 to December 7, 2026. Your old plan ends automatically and the new plan starts January 1, 2027. You can enroll through Medicare.gov, 1-800-MEDICARE or the plan itself.

➤ Do I need to cancel my old Medicare Advantage plan?

No. When you enroll in a new Medicare Advantage plan, Medicare automatically ends your old plan when the new one begins. Canceling separately can leave you with a gap in coverage, so let the new enrollment handle it.

➤ Can I switch Medicare Advantage plans after December 7?

Yes, in some cases. From January 1 to March 31, 2027, Medicare Advantage members can make one change to another plan or to Original Medicare. Special Enrollment Periods also allow changes after certain life events.

➤ What if my Medicare Advantage plan is ending?

You get a non-renewal notice, and your coverage continues through December 31, 2026. You can choose a new plan during Annual Enrollment or a Special Enrollment Period, and you generally have a guaranteed issue right to buy certain Medigap plans.

➤ Can I switch from Medicare Advantage to Original Medicare?

Yes, during Annual Enrollment or the January to March window. Join a standalone Part D plan so you keep drug coverage. You can apply for Medigap, but outside guaranteed issue rights most states let insurers use health questions.

➤ How often can I switch Medicare Advantage plans?

Most people switch once a year during Annual Enrollment. Medicare Advantage members also get one change from January 1 to March 31. Special Enrollment Periods, including switching into a five-star plan, can allow additional changes.

➤ Will switching plans change my doctors?

It can. Each Medicare Advantage plan has its own network. Before switching, confirm each of your doctors, hospitals and pharmacies is in the new plan’s 2027 network, not just its 2026 network, by checking the directory and calling the offices.

➤ When does my new Medicare Advantage plan start?

If you switch during Annual Enrollment, your new plan starts January 1, 2027. If you switch during the January to March window, the new plan generally starts the first day of the month after the plan receives your request.

➤ Do I lose drug coverage when I switch?

Not if you switch to another Medicare Advantage plan that includes drug coverage. If you leave Medicare Advantage for Original Medicare, join a Part D plan so you avoid a coverage gap and a possible late enrollment penalty.

➤ Where can I get free help switching plans?

Free help is available from Medicare Plan Finder on Medicare.gov, 1-800-MEDICARE and your State Health Insurance Assistance Program (SHIP). A licensed agent can also compare plans side by side with you at no cost to you.
