The most costly Medicare Annual Enrollment Period mistakes are missing the December 7 deadline, not comparing your current plan to alternatives, and failing to verify your doctors and medications are still covered. Plans change every year โ€” a plan that was the best value in 2025 may not be in 2026. Reviewing your coverage annually takes 30 minutes and can save hundreds of dollars.

Medicare's Annual Enrollment Period - 4 Biggest Mistakes To AvoidOctober 12, 2024 โ€“ Medicareโ€™s annual open enrollment period (AEP) kicks off on October 15th. The special opportunity for millions of seniors only lasts through Dec. 7.

During open enrollment, millions of Medicare participants have the opportunity to make changes to their coverage. This is especially important in 2024 because some plans are ending while others are reducing benefits or raising costs.

As a result, AEP provides millions of seniors with an opportunity to switch to better coverage. It can also save you a lot of money in 2025.

Here are the 4 Biggest Mistakes To Avoid During Medicare AEP

1. Failing To Read Your Annual Notice Of Change Now

Millions of seniors make the mistake of not learning what changes will impact them beginning January 1st. You canโ€™t make an informed decision about your 2025 Medicare plan coverage if you donโ€™t take the time to learn about any proposed changes for your current plan.

By now you should have received your planโ€™s Annual Notice of Change. These are mailed to all participants with Medicare Advantage (MA or Part C) plans as well as those with stand-alone Medicare prescription drug plans.

It is vitally important that you read it. If you have not received a copy in the mail, or if you discarded it, contact your plan administrator right away and request a copy.

Your notice of change lists the various ways your coverage under your current plan may differ in 2025.

2. Not Considering Changes To Your Health

The second mistake is only looking back and not ahead. Thereโ€™s a good chance that your own health needs have changed over the past year.

Maybe youโ€™ve started taking new medications. Or, maybe a condition was diagnosed that youโ€™ll want to get treatment for in 2025.

All of these need to be factored into the equation when considering coverage for the next year. But you have to think about them now, during AEP when you can still make a change.

3. Failing To Explore New Options, Even If You Are Happy

You may be perfectly happy with the Medicare Advantage or Medicare Part D drug plan that you have today.

But just because youโ€™re satisfied with your coverage doesnโ€™t mean you shouldnโ€™t look into different options. You wonโ€™t know if thereโ€™s a cheaper alternative to your Part D plan, for example, if you donโ€™t look. You may find that thereโ€™s an Advantage plan that offers more benefits at the same price youโ€™re currently paying.

4. Not Speaking With At Least One Local Medicare Insurance Professional

Medicare is a NATIONAL program. But your options are always LOCAL โ€“ based specifically on where you live. For that reason, in addition to calling the many toll-free numbered call centers that are promoted during AEP, it can be very beneficial to connect with at least one local Medicare insurance agent.

He or she will often know such important factors as what your fellow seniors think about various plans. They might know which doctors donโ€™t like Medicare patients. Or which pharmacies are the best for obtaining the lowest price for prescription medications.


Frequently asked questions:

What are the most important things to do before Medicare AEP ends?

Read your Annual Notice of Change, compare your current plan to alternatives available in your ZIP code, verify your doctors and medications are still covered, and check whether a different plan would lower your total annual costs including premiums, copays, and drug costs. Acting before December 7 ensures changes take effect January 1.

What happens if I miss the Medicare Annual Enrollment Period?

If you miss AEP without a qualifying special enrollment event, you generally cannot change your Medicare Advantage or Part D plan until the next AEP. You may be locked into your current plan for the entire year even if benefits change, costs increase, or your preferred doctors leave the network. Missing AEP can be a costly mistake.

Can I look at plan options without sharing my personal information?

Yes. The Associationโ€™s agent directory allows you to find local Medicare insurance agents by ZIP code without entering personal information. Local agents can walk you through plan comparisons confidentially. Medicareโ€™s own Plan Finder tool also allows anonymous browsing before you commit to any plan or provide enrollment details.

How do I know if my current Medicare plan changed for the new year?

Your insurer is required to mail you an Annual Notice of Change before AEP begins each October. This document lists every modification to your current plan taking effect January 1. If you did not receive it or misplaced it, contact your plan administrator directly and request a copy before AEP ends on December 7.

Why should I contact a local Medicare agent instead of a toll-free call center?

Local agents know the specific plans available in your market, understand regional differences in coverage and pricing, and can offer consistent follow-up throughout the year. Call center agents may represent only certain plans and are unlikely to maintain an ongoing relationship. A local broker representing multiple carriers typically provides a more complete and personalized comparison.
