Understanding Medicare can feel overwhelming, especially when it comes to renewing your plan or switching coverage. You might be asking yourself, do I need to re enroll in Medicare every year? Or wondering how and when you can change coverage between Original Medicare, Medicare Advantage, and Medicare Supplement plans. This guide will walk you through the renewal process, explain your switching options, and show how an AEC Insure licensed broker can help you get the most from your Medicare benefits.

Do You Need to Renew Medicare Every Year?
The simple answer is no, you do not have to re enroll in Medicare every year if you want to keep your current plan. Original Medicare (Part A and Part B) automatically continues as long as you pay your Part B premium. You do not need to take any action to renew it annually.
However, if you have a Medicare Advantage plan or a Medicare Prescription Drug Plan (Part D), you have the option to review and change your coverage during the Annual Election Period (AEP), which runs from October 15 to December 7 each year. During this time, you can:
Switch from Original Medicare to a Medicare Advantage plan
Change from one Medicare Advantage plan to another
Switch Medicare Advantage plans back to Original Medicare
Enroll in or change a Part D prescription drug plan
If you want to keep your Medicare plan without changes, you do not need to re enroll or renew during this period. Your coverage will automatically continue into the next year.
When and How to Switch Between Original Medicare and Medicare Advantage
You can switch between Original Medicare and Medicare Advantage during specific times:
Annual Election Period (Oct 15 - Dec 7): Switch from Original Medicare to Medicare Advantage or vice versa.
Medicare Advantage Open Enrollment Period (Jan 1 - Mar 31): If you already have a Medicare Advantage plan, you can switch to a different Medicare Advantage plan or return to Original Medicare.
To make a change, you can enroll through the Medicare website, call Medicare, or work with a licensed broker like AEC Insure who can guide you through your options and help with paperwork.
Switching from Medicare Advantage to Medicare Supplement Plans
Switching from a Medicare Advantage plan to a Medicare Supplement (Medigap) plan is possible but comes with important considerations.
When you can switch: You can switch during the Medicare Advantage Open Enrollment Period (Jan 1 - Mar 31) or during the Annual Election Period (Oct 15 - Dec 7). However, enrolling in a Medigap plan requires you to have Original Medicare, so you must first switch back to Original Medicare.
Medical underwriting: Unlike Medicare Advantage, Medigap plans often require medical underwriting outside your initial enrollment period. This means insurers can deny coverage or charge higher premiums based on your health.
Advantages of Medigap: Offers predictable out-of-pocket costs, covers many expenses not covered by Original Medicare, and provides nationwide coverage.
Disadvantages of Medigap: Usually higher monthly premiums than Medicare Advantage, no prescription drug coverage (you need a separate Part D plan), and no extra benefits like vision or dental.
Switching back to Medigap can be a good choice if you want more predictable costs and broader coverage, but it’s important to understand the enrollment guidelines and potential underwriting risks.
Enrollment Guidelines for Medicare Advantage and Medigap Plans
Understanding enrollment rules helps you avoid gaps in coverage or unexpected costs.
Medicare Advantage Enrollment Guidelines
Must be enrolled in Original Medicare (Parts A and B).
Can enroll during Initial Enrollment Period (IEP), Annual Election Period (Oct 15 - Dec 7), or Medicare Advantage Open Enrollment Period (Jan 1 - Mar 31).
Must live in the plan’s service area.
Can only have one Medicare Advantage plan at a time.
Medigap Enrollment Guidelines
Must have Original Medicare (Parts A and B).
Best time to enroll is during your Medigap Open Enrollment Period, which lasts six months starting the month you turn 65 and enroll in Part B.
During this period, insurers cannot deny coverage or charge more due to health conditions.
Outside this period, medical underwriting applies, and coverage may be denied or cost more.

Pay your Part B premium on time.
Review any notices from your plan about changes in coverage or costs.
If you have a Medicare Advantage or Part D plan, check for any changes during the Annual Election Period.
