A Message to Our Medicare Advantage Members

What To Do Next

You have options. Here are the steps we recommend to make sure you have health coverage starting January 1, 2027.

Review Your Options During Open Enrollment

Medicare Open Enrollment runs from October 15 to December 7, 2026. During this window, you can compare Medicare plans and choose a new plan. Any plan you pick during Open Enrollment will start on January 1, 2027 so your coverage will be seamless.

Compare Plans Using Free Resources

Comparing plans can feel overwhelming. See the “Find a New Plan” section below for free tools and local counselors who can help you find the best option at no cost to you. Join another Medicare Advantage plan in your area, or return to Original Medicare, with optional Part D or a Medigap (Medicare Supplement) policy.

If Choosing Original Medicare, Act on Your Medigap Rights by March 4, 2027

If you plan to return to Original Medicare, you have a special guaranteed right to buy a Medigap (Medicare Supplement) policy. This right expires 63 days after your coverage ends, which means you must purchase a Medigap policy by March 4, 2027. Learn about your Medigap rights or visit Medicare.gov to learn more about Medigap.

Enroll in a New Plan by December 7, 2026

To make sure you have coverage on January 1, 2027, enroll in your new plan by December 7, 2026. If you have not enrolled by that date, you still qualify for a Special Enrollment Period (SEP) because your plan is ending. A SHIP counselor or licensed agent can help you understand your options.

Use Your Reward Dollars Before March 31, 2027

If you have earned reward dollars for health activities through our Rewards & Incentives Program, you have until March 31, 2027 to spend them. Rewards can no longer be earned after December 31, 2026, but the rewards can still be used. Log in to your Member Portal for more information.

Save Information from Your Portal

You will still have access to your Member Portal, including your claims history, Explanations of Benefits, and other documents, through March 31, 2028. We recommend downloading and saving any records you may need before that date.

What Happens If You Don’t Choose a New Plan by December 31, 2026

Medicare Plus (HMO) & Medicare Complete (HMO) Members: If you do not enroll in a new Medicare Advantage plan before December 31, 2026, you will lose your prescription drug coverage and will only be covered by Original Medicare beginning January 1, 2027.

Medicare Guardian (HMO) Members: If you do not enroll in a new Medicare Advantage plan before December 31, 2026, you will only be covered by Original Medicare beginning January 1 2027.

You still have time

If you choose to enroll in another Medicare Advantage plan, you may opt to enroll during a Special Enrollment Period that runs from December 8, 2026 through February 28, 2027. Important: If you join a new plan after December 31, 2026, your new coverage will not begin until the first day of he month after you enroll.

If you do not enroll in a plan with prescription drug coverage, such as a Part D Plan (PDP) or a Medicare Advantage Plan with Part D (MA-PD), by February 28, 2027, you may have to pay a lifetime Part D late enrollment penalty if you join a Medicare drug plan later.

Frequently Asked Questions

What happens to my coverage on January 1st if I do nothing? 

If you take no action before your Medicare Advantage plan ends on December 31, 2026, you will automatically revert to Original Medicare (Part A and Part B) on January 1, 2027.

Do I qualify to buy a Medigap plan? 

Yes. With your Medicare Advantage plan ending coverage, you automatically qualify for a federal Guaranteed Issue (GI) right to purchase a Medigap policy.

How long do I have to buy a Medigap plan? 

You can apply for Medigap as early as 60 days before your current Medicare Advantage coverage officially ends. Applying early ensures you avoid any gap in medical coverage. You must apply no later than 63 days after your Medicare Advantage coverage ends, which for our members will be March 4, 2027.

If you enroll in a new Medicare Advantage plan, you cannot also use Medigap.

What will happen with my prescriptions? Does Medigap cover my prescription drugs like my old Medicare Advantage plan did? 

Medigap policies do not cover prescription drugs, nor does Original Medicare. Members must enroll in a standalone Medicare Part D plan to maintain drug coverage and avoid late-enrollment penalties. If you enroll in a Medicare Advantage plan with Part D, you'll contact your new network pharmacy to move your active prescriptions, if necessary.

What if I decide to switch to a different Medicare Advantage plan instead of Original Medicare? 

You are welcome to do so. When your current Medicare Advantage plan is discontinued, you receive a Special Enrollment Period (SEP) that allows you to join another Medicare Advantage plan in your area. Choosing a new Medicare Advantage plan means you are not using your Medigap rights.

If you enroll in a new Medicare Advantage plan between October 15 (start of Open Enrollment) and December 31, your new plan will be effective January 1 with no gap in coverage.

If you enroll in a new Medicare Advantage plan between January 1 and February 28 (the end of your SEP), your new effective date will be the first of the month following your application date.

Can I keep my current doctors and scheduled appointments? 

If you switch to Medigap or Original Medicare - In most cases, yes. Call your doctor's office before your appointment to confirm they accept Original Medicare and give them your new Medicare card and Medigap policy details.

If you switch to a new Medicare Advantage plan – Only if your doctors are in the new plan's provider network. Each Medicare Advantage plan sets its own network of participating doctors and hospitals. To avoid higher costs, or lack

What happens to my supplemental benefits? 

Original Medicare and Medigap do not include routine ancillary benefits, like dental or vision, requiring separate standalone policies or out-of-pocket payment.

Other Medicare Advantage plans may have a variety of different supplemental benefits included. Reach out to any Medicare Advantage plans before enrolling to make sure they can fit your needs.
