➤ When do 2027 Medicare Advantage plans come out?
Plan details for 2027 went live on Medicare Plan Finder on October 1, 2026, shortly after CMS released its national landscape data on September 28, 2026. That means you can already compare premiums, networks and drug coverage for your county before Annual Enrollment opens on October 15.
➤ When can I enroll in a 2027 Medicare Advantage plan?
Annual Enrollment runs from October 15 to December 7, 2026, and any plan you choose takes effect January 1, 2027. You can change your selection during that window as often as you need to, so use the time to compare plans carefully rather than rushing to enroll on the first day.
➤ Why do Medicare Advantage plans change every year?
Insurers redesign their plans every year based on Medicare payment rates and their own costs, and they submit bids to Medicare each June. As a result, premiums, copays, drug lists, provider networks and extra benefits can all shift from one year to the next, which is why your Annual Notice of Change deserves a close read each fall.
➤ When do insurers decide to leave a county?
Those decisions are made when insurers build the bids they submit to Medicare each June, months before the public hears about them. Members learn about an exit in the fall through a non-renewal notice, and coverage continues through December 31, 2026, giving you time to pick a replacement during enrollment.
➤ When are 2027 star ratings released?
CMS publishes Medicare Advantage and Part D star ratings each October, ahead of Annual Enrollment. Plans are scored from one to five stars on quality and member experience, and the ratings appear next to each plan in Medicare Plan Finder, making them easy to factor in when you compare 2027 options.
➤ What if I miss December 7?
In most cases your current plan simply renews for 2027 if you do nothing. If you are in Medicare Advantage, you get another chance to switch plans or return to Original Medicare between January 1 and March 31, 2027, though only one change is allowed in that window.
➤ What should I review once 2027 Medicare Advantage plans are released?
Start with your Annual Notice of Change, which lists exactly what is changing in your current plan for 2027. Then confirm your doctors and hospitals are still in network, check how your prescriptions are covered, and compare premiums, copays and star ratings with other plans in your county.
