Introduction: What Is the Medicare Annual Enrollment Period (AEP)?
The Medicare Annual Enrollment Period, often called the Open Enrollment for the Medicare drug plan, which is part of the open enrollment for Medicare, is a special time each year when people with Medicare can make changes to their health coverage. For 2025–2026, this period runs from October 15 to December 7, 2025. It applies mainly to those enrolled in Medicare Advantage plans and Medicare Part D prescription drug plans.

This period is crucial because Medicare plans frequently update their benefits, premiums, and provider networks, which can impact your out-of-pocket costs and access to services.

Each year, Medicare plans can change their benefits, costs, and coverage. The Annual Enrollment Period is the only time most people can switch plans or update their coverage, including opting for another medicare advantage plan without a qualifying life event. Any changes made during this time will start on January 1, 2026.
Making the most of the AEP ensures that you are not stuck with a plan that no longer fits your health needs or budget. It also helps you avoid penalties, such as the late enrollment penalty for Medicare prescription drug coverage, which can result if you delay signing up for Part D without other creditable drug coverage.
During AEP, you can join a Medicare plan, review options, or make changes to your coverage:
Switch from one Medicare Advantage plan to another. This allows you to find a plan that better fits your healthcare needs or budget. Whether you want a plan with more comprehensive benefits or one with a different network of providers, AEP is your opportunity to make that change.
Drop your Medicare Advantage plan and go back to Original Medicare. If you find that a Medicare Advantage plan no longer suits your needs, you can return to Original Medicare coverage. Keep in mind that if you switch back, you may also want to consider enrolling in a separate Medicare prescription drug plan to maintain drug coverage.
Enroll in, drop, or change a Medicare Part D prescription drug plan. Prescription drug coverage can vary between plans, so AEP is the time to review your medications and ensure your plan covers them at a reasonable cost. You can add a new drug plan, switch to a plan with better coverage, or drop your current plan if you have other creditable drug coverage.
Making these changes during the Annual Enrollment Period helps you avoid gaps in coverage and potential late enrollment penalties. It’s important to review your current plans, compare plan options, and consider any changes in your health or prescription drugs before making decisions during AEP.
To get the most from AEP, avoid these mistakes:
Waiting until the last week to review your options. Procrastinating can limit your ability to carefully compare plans and make informed decisions, potentially leading to suboptimal coverage or higher costs.
Assuming your current coverage will stay the same next year. Medicare plans often change their benefits, premiums, and provider networks annually. Failing to review the Annual Notice of Change (ANOC) and other communications can result in unexpected out-of-pocket expenses or loss of preferred providers.
Ignoring updates to prescription drug coverage. Formularies—the list of covered medications—can change yearly. It’s crucial to verify that your medications remain covered and understand any changes in copayments or restrictions.
Not checking if your doctors and providers are still in your plan’s network. Provider networks can shift, and seeing out-of-network providers may lead to higher costs or denied claims. Always confirm your healthcare providers participate in your chosen plan’s service area.
Overlooking potential eligibility for Special Enrollment Periods (SEPs). Certain life events, such as moving, losing other health coverage, or qualifying for Medicaid, may allow you to enroll or change plans outside of the Annual Enrollment Period.
Neglecting to consider the Medicare Advantage Open Enrollment Period. If you’re already enrolled in a Medicare Advantage plan, you have another opportunity from January 1 to March 31 to make a one-time change to a different Medicare Advantage plan or return to Original Medicare with a separate Medicare drug plan.
