Your Guide to the Medicare Annual Enrollment Period (AEP) for 2025

Every fall, millions of Americans have the opportunity to review and potentially change their Medicare plans during the Medicare Annual Enrollment Period (AEP). For 2025, this window runs from October 15 through December 7, 2025, with any changes becoming effective January 1, 2026.

What Is the Medicare Annual Enrollment Period (AEP)?

The Medicare Annual Enrollment Period (sometimes called the Medicare Open Enrollment Period or Annual Election Period) is when beneficiaries can make important changes to their Medicare coverage. During this time, you can:

• Switch between Original Medicare and Medicare Advantage (Part C)

• Change or add a Medicare Part D prescription drug plan

• Switch from one Medicare Advantage plan to another

• Make changes without medical underwriting (unlike Medigap policies)

  
  

This is the best opportunity to ensure your coverage meets your health and budget needs for the coming year.

Key Medicare Enrollment Dates for 2025

• October 1, 2025 – Insurance companies release plan details for 2026.

• October 15 – December 7, 2025 – Medicare Annual Enrollment Period.

• January 1, 2026 – New plan choices take effect.

  
  

Remember: The last change you make before December 7 is the one that counts.

What You Can Do During AEP

During Medicare’s Annual Enrollment Period, you can:

• Enroll in, switch, or drop a Medicare Advantage (Part C) plan

• Join, change, or drop a Medicare Part D prescription drug plan

• Move from Medicare Advantage back to Original Medicare, or vice versa

  
  

There’s no limit on how many changes you can make—your final selection before the deadline is the one that applies.

Why Medicare AEP 2025 Is Especially Important

For 2025, there are some significant Medicare updates:

• Premiums and deductibles – Part B premium is $185/month; Part D averages $46.50/month.

• Out-of-pocket drug cap – A new $2,000 maximum out-of-pocket limit for prescription drug costs starts in 2025.

• Medicare Advantage plan growth – Many Advantage plans add extras like dental, vision, and fitness benefits. However, these often come with limited provider networks, so review carefully before enrolling.

  
  

How to Prepare for the 2025 Medicare Enrollment Period

1. Review your current plan. Look at your Annual Notice of Change to see if your costs, coverage, or network will shift.

2. Compare plans carefully. Consider premiums, deductibles, provider networks, drug formularies, and added benefits.

3. Use trusted tools. The Medicare Plan Finder and local SHIP counselors can provide unbiased guidance.

4. Don’t wait until December. Start reviewing your options early to avoid last-minute stress.

5. Understand what happens after AEP. If you miss it, you’ll keep your current plan unless you qualify for a Special Enrollment Period. Medicare Advantage members also have another window from January 1 – March 31 to make a one-time switch.

   
   

Understanding Medicare Options

Navigating Medicare can be overwhelming. It's essential to understand the different parts of Medicare and how they work together.

Original Medicare vs. Medicare Advantage

Original Medicare includes Part A (hospital insurance) and Part B (medical insurance). It allows you to see any doctor or specialist who accepts Medicare. However, it does not cover everything. You may need a separate Medicare Part D plan for prescription drugs.

Medicare Advantage, or Part C, is offered by private insurance companies. It bundles Part A, Part B, and often Part D into one plan. Many Medicare Advantage plans also offer additional benefits like dental and vision coverage. However, these plans may have network restrictions.

The Importance of Prescription Drug Coverage

Prescription drug coverage is vital for many beneficiaries. Medicare Part D plans help cover the cost of medications. During AEP, you can switch your Part D plan or enroll in one if you haven't yet. Make sure to review the formulary to see if your medications are covered.
