What to do before December 7
If you are in a Medicare Advantage plan today, your plan must send you an Annual Notice of Change by September 30 that spells out exactly what is different for 2027. Read it before the Annual Enrollment Period (Open Enrollment), which runs October 15 through December 7.
If your plan is leaving your county, you will get a separate notice and a Special Enrollment Period to choose new coverage. If you do nothing, you may be returned to Original Medicare without drug coverage, so it is worth acting during the window.
A licensed agent can check your doctors and prescriptions against the plans that will actually operate in your county next year. For unbiased help, contact Medicare.gov or 1-800-MEDICARE.
