Medicare Open Enrollment 2027: the Annual Enrollment Period, Oct. 15 to Dec. 7, 2026

Medicare Open Enrollment and Medicare Annual Enrollment are two names for the same window, the Annual Enrollment Period (AEP): from October 15 to December 7, 2026, anyone with Medicare can join, switch or drop a Medicare Advantage or Part D plan, for coverage that starts January 1, 2027.

It is on now: 52 days left to December 7, 2026.

This page keeps the dates, what the window allows and what changes for the year in one place, with every state's plan-change and top-rated pages below. Program-level information only: no plan is named, ranked or recommended.

What you can do during Open/Annual Enrollment 2027

A change made in the window starts January 1, 2027. If you do nothing and your plan continues, you stay in it; your plan's Annual Notice of Change, mailed by September 30, lists what is different.

Medigap (Medicare Supplement) policies are not part of this window: their own open enrollment is the six months after you enroll in Part B at 65. Our Medigap guides by state cover it.

Good to know

Open Enrollment, Annual Enrollment: the questions people ask

Is Medicare Open Enrollment the same as Medicare Annual Enrollment?
Yes. Medicare's name for the fall window is the Annual Enrollment Period (AEP); most people call it Open Enrollment. It runs October 15 to December 7 every year, and a change made in it starts January 1. The Medicare Advantage Open Enrollment Period, January 1 to March 31, is a different, smaller window for people already in a Medicare Advantage plan.
When does Medicare Open Enrollment for 2027 start and end?
October 15 to December 7, 2026. Coverage chosen in the window starts January 1, 2027.
What can I change during the Annual Enrollment Period?
Join, switch or drop a Medicare Advantage plan; move between Medicare Advantage and Original Medicare; join, switch or drop a Part D drug plan. Medigap (Medicare Supplement) policies have their own rules and are not part of this window.
What if my Medicare Advantage plan is leaving for 2027?
Your plan must tell you in writing, and you get a Special Enrollment Period to choose new coverage in addition to the fall window. If you do nothing you return to Original Medicare, without drug coverage unless you join a Part D plan. The plan-change pages on this site show how many plans are leaving each county for 2027.
Do I have to do anything if I like my plan?
No. If your plan continues next year and you make no change, you stay in it. Read the Annual Notice of Change it mails by September 30: premiums, drug coverage, networks and benefits can change even when the plan continues.
Where can I get help that does not sell plans?
Medicare's Plan Finder at Medicare.gov, 1-800-MEDICARE and your State Health Insurance Assistance Program (SHIP) give free, unbiased help. This site publishes program-level information from CMS files and does not rank or recommend plans.

Dates and rules are Medicare’s and apply nationwide; confirm your own at Medicare.gov or 1-800-MEDICARE. Plan counts are from the CMS Medicare Advantage Landscape files. No plan is ranked or recommended.
