Every year, Medicare allows individuals to make changes to their Medicare plans. This is called the “Annual Enrollment Period” (AEP), and it runs from October 15th through December 7th [1]. Although this enrollment period may seem easy enough to understand, many individuals find themselves a bit confused by AEP, what they need to do during this time, and why their decision matters. We’re here to clear up any confusion you may have. Keep reading to learn more!
What is AEP, and Why Does It Matter?
The Annual Enrollment Period, also referred to as the “Open Enrollment Period,” is the time when one can make changes to their Medicare plan(s) and coverage. This window exists so that people don’t feel stuck with a plan that no longer serves or works for them. Each year, plans may change their costs, coverage, benefits, and/or provider networks. Because of this, the plan you had last year may not work for your healthcare needs this year. This makes AEP so helpful; it allows people to take the reins of their wellness and make appropriate healthcare decisions.
When Is AEP in 2026?
AEP runs from October 15 until December 7 in 2026, and takes effect on January 1 of 2027 [2]. This means that if you decide to make changes to your Medicare plan(s) or coverage, you’ll do so any time from October 15 through December 7. Then, the new plan(s) coverage you chose will be active starting January 1 of the following year.
Please note that Medicare Advantage Plans, also known as “Part C,” have a separate enrollment period. Open enrollment for Medicare Advantage Plans runs January 1 through March 31, or within the first 3 months you get Medicare [3].
What Can You Do During AEP
Switching plans or enrolling in a new one may seem like an easy process. While selecting a new plan is intuitive, critical thinking and reasoning must go into the decision process beforehand. During—or better yet, before—AEP is a good time to review your current coverage. Ask yourself about how this plan has been working for you and if anything is missing. From there, you can assess whether you should drop, switch, or keep your plan.
People who find that their plan meets their health needs, is within their budget, and has their preferred in-network providers may decide to keep their plan.
People who find that their current plan does not meet their current health needs, is too expensive, or does not include their preferred in-network providers may decide to drop their plan and then switch to a different one.
Your health has a huge influence on your overall quality of life, and health insurance can be a main factor in getting the healthcare you need to survive and thrive [4]. That is why choosing the right Medicare plan for you is an important decision that requires careful thought. If you are struggling to understand your current plan or plan options, please ask for support from a loved one, a licensed Medicare broker, or your care team at Greater Good Health.
What Happens If You Don’t Do Anything?
If you do not do anything during AEP, the plan you currently have will automatically continue the next year. Even if you are content with your current plan, it’s worth reviewing for potential cost or coverage updates. Medicare plans often make tweaks in what is covered, co-pay amounts, overall costs, or in-network providers [5, 6]. The only way you’ll stay informed about these changes is if you review them!
Getting Ready Before AEP Starts
You’ll receive an Annual Notice of Change (ANOC) letter highlighting your current plan’s potential changes that would take effect on January 1, including changes in cost, coverage, network, and more [7]. This letter will be delivered to you in September [7]. Once you receive your ANOC letter, the best thing you can do is read it thoroughly and assess whether your plan still fits your needs. If you don’t receive your ANOC letter on time or have questions about plan changes, reach out to your plan provider’s customer service line, which should be listed on the letter [8]. Likewise, you can also contact Medicare directly at 1-800-MEDICARE (1-800-633-4227) [8].
