Medicare’s Annual Enrollment Period (AEP) happens every year from October 15 to December 7, giving beneficiaries an important window of time to review and change their Medicare coverage. Whether you’re new to Medicare or you’ve been enrolled for years, it’s essential to understand what changes you can make during this time—and how those changes might benefit you.
In this article, we’ll walk through:
- What the Annual Enrollment Period is
- The types of changes you can make
- What options are available for Medicare Advantage (Part C) and Prescription Drug Plans (Part D)
- How to evaluate your current plan
- Tips for making the most of the AEP
- How Las Vegas Medicare can help you navigate it all
What Is Medicare’s Annual Enrollment Period (AEP)?
The Annual Enrollment Period, sometimes called Open Enrollment, is the time when all Medicare beneficiaries can make changes to their Medicare Advantage (Part C) and Prescription Drug Plans (Part D) for the upcoming year. Any changes you make during AEP go into effect on January 1 of the following year.
AEP is not the time to sign up for Medicare for the first time—that’s handled during your Initial Enrollment Period when you turn 65 or become eligible due to disability. Instead, AEP is your yearly opportunity to reassess your current coverage and decide if it’s still the right fit for your health and financial needs.
What Changes Can You Make During AEP?
During the Medicare Annual Enrollment Period, you can:
- Switch from Original Medicare (Part A and Part B) to a Medicare Advantage plan (Part C)
- Switch from a Medicare Advantage plan back to Original Medicare
- Change from one Medicare Advantage plan to another
- Join a Medicare Part D Prescription Drug Plan if you don’t already have one
- Switch from one Part D plan to another
- Drop your Part D coverage entirely
These options give you the flexibility to adjust your plan if:
- Your health needs have changed
- Your medications are no longer covered by your current plan
- Your doctor is no longer in-network
- You want additional benefits like dental, vision, or hearing
- Your monthly premium or out-of-pocket costs have gone up
Understanding Medicare Advantage (Part C) During AEP
Medicare Advantage plans (Part C) are offered by private insurance companies approved by Medicare. These plans combine your Part A (hospital coverage) and Part B (medical coverage) into one convenient plan. Many also include Part D drug coverage and extra benefits like:
- Dental and vision care
- Hearing aids
- Gym memberships (like SilverSneakers®)
- Over-the-counter allowances
- Transportation to medical appointments
Changes You Can Make with Part C:
- Switch from one Medicare Advantage plan to another
Maybe a different plan in your area offers better drug coverage or lower copays. - Switch from Original Medicare to Medicare Advantage
If you’re currently on Original Medicare and want more benefits or predictable costs, a Part C plan might be worth exploring. - Go back to Original Medicare from Medicare Advantage
If you’re unhappy with your current Medicare Advantage plan, AEP is the time to return to Original Medicare and (optionally) add a Part D drug plan and/or a Medigap plan.
Remember: If you’re switching back to Original Medicare and want a Medicare Supplement (Medigap) plan, you might be subject to medical underwriting unless you’re within your initial 6-month Medigap enrollment window or another special enrollment period.
Understanding Prescription Drug Plans (Part D) During AEP
Part D covers prescription drugs, and it can be added to Original Medicare or included in a Medicare Advantage plan. Every year, plans can change:
- Which drugs they cover (the formulary)
- What you pay for those drugs
- Which pharmacies are in-network
These changes are outlined in the Annual Notice of Change (ANOC), which your current plan will send to you in September.
Changes You Can Make with Part D:
- Switch from one Part D plan to another
This is the most common AEP change. You may find a plan that covers more of your medications at a lower cost. - Add Part D coverage if you currently have Original Medicare without drug coverage
This can help avoid the Part D late enrollment penalty. - Drop Part D coverage (though this is not recommended unless you have other credible drug coverage).
Choosing the right drug plan matters—especially if you take multiple medications. A small difference in copays or covered drugs could mean hundreds of dollars in savings.
Evaluating Your Current Plan
Before making changes, ask yourself these questions:
- Have my health needs changed?
- Are my current doctors and specialists still in-network?
- Are my medications still covered and affordable?
- Did my premiums, deductibles, or copays increase?
- Am I satisfied with the customer service and benefits I’m getting?
If the answer to any of these questions is “no,” it’s time to shop around. Even if you’re happy with your plan, it’s smart to compare options annually—plans change, and new ones may offer better value.
How to Make the Right Choice
Making Medicare decisions can feel overwhelming, especially when you’re bombarded with ads, flyers, and phone calls during AEP. But there’s good news: You don’t have to do it alone.
Working with a local, independent Medicare agency like Las Vegas Medicare gives you access to:
- Personalized plan comparisons
- Unbiased advice across multiple insurance carriers
- Help finding the right doctors, hospitals, and drug coverage
- Ongoing support throughout the year—not just during enrollment
Don’t Miss the Deadline
The Annual Enrollment Period ends on December 7, and any changes you make during this time will start on January 1. If you miss the deadline, you may be locked into your current plan for another year—unless you qualify for a Special Enrollment Period (SEP) due to circumstances like moving or losing other coverage.
Final Thoughts
Medicare’s Annual Enrollment Period is your chance to review your plan, compare your options, and make changes that better suit your health and your wallet. Whether you want to:
- Switch Medicare Advantage plans,
- Join a Part D drug plan,
- Or just review your options to make sure you’re not overpaying—
Now is the time to act.
