Medicare Special Enrollment Period · Updated June 2026

5-star Medicare plan in your area? You can switch once a year

A qualifying life event can open a Special Enrollment Period to change your Medicare coverage outside the normal windows. Here's exactly what applies when a 5-star plan is available.

Quick answer: If a Medicare Advantage plan, Medicare Cost plan, or Medicare drug plan with an overall 5-star quality rating is offered in your area, you can switch to it. You can use this Special Enrollment Period once between December 8, 2025 and November 30, 2026.

Frequently asked questions

How do I find a 5-star Medicare plan near me?

Medicare publishes overall star ratings each fall. Look for plans showing a 5-star overall rating in your ZIP code on the official Medicare Plan Finder. If one is offered where you live, you can switch to it once between December 8, 2025 and November 30, 2026.

Can I use the 5-star SEP more than once a year?

No. The 5-star Special Enrollment Period can be used only once during the annual window. Other life events (moving, losing coverage) may give you separate chances to change plans.
