Annual Enrollment Period (AEP)
The annual Medicare Enrollment Period runs from October 15, 2025 through December 7, 2025. During this time, anyone with Medicare can add, drop, or switch Medicare health plans and prescription drug coverage for the upcoming year.
What Changes Can Be Made During AEP?
- Switch between Original Medicare and Medicare Advantage (Part C)
- Change from one Medicare Advantage plan to another
- Join or drop a Medicare Prescription Drug Plan (Part D)
- Switch Part D plans
Medicare Advantage Open Enrollment Period
The Medicare Advantage Open Enrollment Period spans from January 1, 2026 – March 31, 2026. This period is exclusive to people already enrolled in a Medicare Advantage plan, allowing them to switch plans or revert to Original Medicare.
Special Enrollment Periods (SEPs)
Outside of the standard enrollment periods, you may sign up for or change plans if you qualify for a Special Enrollment Period, commonly triggered by events such as losing other coverage or moving.

What Are Medicare Enrollment Period Triggering Events?
Understanding Medicare Enrollment Period triggering events can help you avoid gaps in your healthcare coverage. A triggering event is essentially a qualifying life event that allows you to enroll in, change, or leave a Medicare plan outside of the standard enrollment periods.
Here are some common triggering events:
1. Turning 65
When you first turn 65, you enter your Initial Medicare Enrollment Period, which starts three months before your birth month and continues three months after. Missing this initial period could result in penalties or delayed coverage.
2. Losing Employer-Sponsored Health Coverage
If you’re over 65 and lose coverage from your employer or your spouse’s employer, this triggers a Special Medicare Enrollment Period (SEP). This event provides an opportunity to enroll in Medicare Part B without facing late-enrollment penalties.
3. Moving to a New Area
Relocating to a different county or state can trigger an SEP because your existing Medicare Advantage (Part C) or Prescription Drug Plan (Part D) may not be available in your new location. This gives you the chance to enroll in a new plan tailored to your new area.
4. Medicaid Eligibility Changes
If you gain or lose Medicaid eligibility, you’ll qualify for an SEP. Changes in your financial situation that affect your Medicaid eligibility status also allow you to reconsider your Medicare coverage options.
5. Losing or Gaining Extra Help (Low-Income Subsidy)
Changes in eligibility for the Extra Help program—which helps pay prescription drug costs—also trigger a Special Enrollment Period. Beneficiaries receiving this assistance can make plan adjustments to ensure optimal coverage.
6. Plan Termination or Reduction
If your Medicare Advantage or Part D plan stops providing coverage or significantly reduces benefits, this automatically triggers a Medicare Special Enrollment Period. You’ll have the opportunity to find another suitable plan.
7. Living in or Leaving an Institution
Entering or leaving long-term care facilities, such as skilled nursing facilities or assisted living, qualifies as a triggering event. Beneficiaries in these situations have additional flexibility to adjust their Medicare coverage.
Why Triggering Events Matter
Being aware of triggering events is crucial because missing one can limit your coverage options, cause gaps in your coverage, or even lead to penalties and higher premiums. If you’re unsure whether a life change qualifies as a triggering event, it’s always a good practice to consult Medicare directly or speak with a licensed insurance broker.
Remember, Medicare plans and rules can change annually, so staying informed ensures you make the most of your coverage opportunities.
