Medicare Advantage (Part C) plans offer flexibility and additional benefits beyond Original Medicare. However, enrolling isn’t always possible year-round. That’s where Special Enrollment Periods (SEPs) come in. In 2025, SEPs offer eligible individuals the opportunity to join, switch, or drop a Medicare Advantage plan outside the standard enrollment windows.
In this guide, we’ll break down who qualifies for a SEP in 2025, what types of events trigger eligibility, and what to expect when changing plans. We’ll also address trending questions related to Medicare Advantage for 2025.
What Are Medicare Advantage Special Enrollment Periods?
A Special Enrollment Period (SEP) is a window of time outside the Annual Election Period (AEP) and Open Enrollment Period (OEP) that allows you to enroll in or make changes to your Medicare Advantage plan if you experience certain qualifying life events.
Key SEP Dates
Unlike AEP (October 15 – December 7) or OEP (January 1 – March 31), SEPs don’t have fixed dates — they depend on the qualifying event. Typically, the SEP lasts two months (or 60 days) after the event.

4. Medicare & Medicaid Dual Eligibility

5. 5-Star Medicare Advantage Plan SEP (5-Star SEP)
- If a 5-star rated Medicare Advantage plan is available in your area, you can switch once per year to that plan between December 8 and November 30.

Frequently Asked Questions (FAQs)
What Is the Best Medicare Advantage Plan for 2025?
The best plan varies based on location, healthcare needs, and budget. However, 5-star plans are considered top-tier by Medicare and are worth exploring if available in your area. Compare networks, premiums, copays, and extra benefits (like dental, vision, and hearing).
What Is the Maximum Out-of-Pocket for Medicare in 2025?
In 2025, the maximum out-of-pocket (MOOP) limit for Medicare Advantage plans is $8,850 for in-network services. Many plans offer lower MOOP thresholds. Be sure to check your plan’s summary of benefits.
What Is a 5-Star SEP?
A 5-Star SEP allows Medicare beneficiaries to switch to a plan with a 5-star CMS rating once between December 8 and November 30 of the following year. This is especially valuable if you’re unhappy with your current plan or missed AEP.
What’s the Difference Between AEP and OEP?
- AEP (Annual Election Period): October 15 – December 7. You can join, switch, or drop Medicare Advantage or drug plans.
- OEP (Open Enrollment Period): January 1 – March 31. Only for those already enrolled in a Medicare Advantage plan. You can switch to another Medicare Advantage plan or return to Original Medicare.
