The one piece of Medicare mail worth opening
Between now and September 30 your plan has to send you a document explaining exactly what it is changing on January 1. Almost nobody reads it. It is the only Medicare mail that is actually about you.
Every fall the mailbox fills up. Glossy postcards, envelopes marked urgent, invitations to seminars with a free lunch attached. Most of it is advertising from companies you have never done business with, and throwing it away costs you nothing.
One envelope is different. It is called the Annual Notice of Change, usually shortened to ANOC, and your current plan is required to send it to you by September 30. It is not advertising. It is a plain accounting of what your plan is doing differently starting January 1, and it is specific to the plan you are actually enrolled in.
It is also, frankly, dull. Which is why it ends up in the recycling next to the pizza coupons.
Why it matters more than it looks like it does
Your Medicare plan renews automatically. You do nothing, and coverage continues into January. That feels like stability, and for most people most years it roughly is.
But the plan itself is not standing still. Insurers rebuild these products every year. The premium moves. The list of covered drugs gets revised, and medications move between tiers, which changes what you pay at the counter. Doctors and hospitals join networks and leave them. Copays for specialists, imaging, and hospital stays get adjusted. The maximum you can be asked to pay out of pocket in a year is reset.
None of that requires your agreement. The ANOC is simply the notification that it happened.
The plan that fit you perfectly in 2024 may not be a reasonable fit now, and nothing about the renewal process will tell you that in plain language.
How to read it in ten minutes
You do not need to read the whole booklet. Four things carry almost all of the risk:
- The monthly premium. Front page, usually a simple this year versus next year comparison.
- Your prescriptions. Take your actual pill bottles and find each drug in the formulary section. You are looking for a tier change or a drug that dropped off the list entirely. This is where most unpleasant surprises live.
- Your doctors. If you are in an Advantage plan, confirm the physicians you want to keep are still in network for next year. Networks change quietly.
- The out of pocket maximum. The most you could be asked to pay in a bad year. Worth knowing even when nothing else changed.
If all four look the same or close to it, you are probably fine and can stop there. If any of them moved meaningfully, that is your signal to compare options.
The window to do something about it
Annual Enrollment runs October 15 through December 7. That is when you can switch Advantage plans, change or add a Part D plan, or move between Original Medicare and Advantage. Whatever you choose takes effect January 1.
Outside that window your choices narrow considerably. This is why the ANOC lands in September rather than December. It is meant to give you a few weeks to read it before the door opens.
What we would suggest
Put the envelope somewhere you will see it rather than opening the mail over the trash can. When you sit down with it, have two things in hand: a current list of your prescriptions with dosages, and the names of the doctors you want to keep. Those two lists answer most of the question.
If it looks fine, do nothing. Automatic renewal is a legitimate outcome and most years it is the right one.
If something moved and you want a second set of eyes, that is what a review is for. It takes about half an hour, there is no cost, and a good share of them end with us telling someone their current plan is still the best thing available to them.
