Plain-English guides to the Medicare annual review: how to read your Annual Notice of Change, the dates that matter, and what to check before December 7.

By the Retire Wise Guide editors · Updated October 2026

These guides don't sell anything and don't recommend any particular coverage. They don't mention companies or plans. They're written so you can review your own documents with your own judgment, before you talk to anyone.

If you only read one, start with the first: the letter your plan sent in September is where every change for next year is written down.

Where to look first, and how to finish in ten minutes. 02Why your plan can change even if you do nothingWhat a plan can change every January 1, and why staying put doesn't freeze your coverage. 03The Medicare calendar: key datesA handful of windows, all strict.
