Lookout For Non Renewal of Your Plan

You should be checking your mail this month. Plans that end in 2026 will send out non-renewal notifications by October. This will trigger a Special Registration Period from February 28 to March 31. Act quickly by December 31 to avoid gaps. You have until the 1st of the following month to make changes.

This is a problem that thousands of people face every year, particularly with the service area reductions by large insurers such as UnitedHealthcare. Medicare Plan Finder on Medicare.gov can help you find replacements for your drugs and doctors. Just enter your zip code and your doctor’s name to get a list tailored just for you. State Health Insurance Assistance Programs counselors can help you compare options without any sales pressure.

Use Medicare Advantage Open Enrollment

From January 1, 2026 through March 31, 2026 you can switch from a Medicare Advantage Plan to another MA Plan or Original Medicare. There are no Part D switches, but this is your safety net in case January coverage fails you, such as higher copays and out-of network doctors. Enroll early as the changes will begin on the first day of the following month.

Compare via Plan Finder to find lower premiums, (which will be slightly less for 2026 on average) or additional benefits like dental. You can’t enroll in MA if you’re on Original Medicare. Save that for the next fall’s open enrollment.
