The Annual Notice of Change: Is My Doctor Still in Network Next Year?

If you have a Medicare Advantage or stand-alone drug plan, one letter arrives every fall: the Annual Notice of Change, or ANOC — 연례 변경 통지서 in Korean. Plans are expected to send it by around September 30.

Its job is to tell you what changes about your plan next year — not what it is today, but what it becomes on January 1. Doctors, hospitals, pharmacies, the drug list, and your costs can all change.

It is the most useful mail a Medicare member gets all year, and the piece most often thrown away unopened.

I say this gently, because I have seen it at many kitchen tables. The envelope is thick, the print is small, every word is in English, and it looks like ordinary advertising mail.

So it goes on the table, then into a drawer, then out with the rest. That is not carelessness — setting aside a heavy letter in a language you did not grow up in is reasonable.

This letter is the reason I do this work. I kept meeting Korean seniors who got important Medicare mail every year with no one to read it with them — not because they could not understand, but because no one explained it in their language.

This is the question underneath all the others, and the honest answer is: you cannot assume. Hospital systems, medical groups, and insurers renegotiate contracts every year. A provider in network this year may not be next year.

This is not theoretical. Korean-language news in Los Angeles reported this August that Korean seniors here increasingly find a hospital or medical group they have used for years is out of their plan's network the next year. The plan did not disappear. The network around it changed.

I will not tell you which providers will or will not be in network next year, and you should be careful with anyone who does. It has to be checked one at a time, for your plan and your doctors.

Open it at the kitchen table with a pen. You are not reading it like a book — you want the items that touch your actual life.

Write your answer beside each item. If you cannot find something, mark it with a question mark and keep going.

This is the misunderstanding I correct most often in the fall: people see the same monthly premium as last year and file the letter away.

But the premium is one line. A plan can hold it exactly where it is and still change its network, move medications to other tiers, drop a drug from the list, adjust what a specialist visit costs, or change its extra benefit categories.

A plan you were happy with this year can be a different plan next year. That is not a failure on the plan's part — it is how these contracts work, and why the letter exists.

If a doctor or hospital you depend on will not be in the network next year, you generally have two directions. Neither is right for everybody.

The first is to change doctors: keep your plan, move to a provider inside its network. For some families that is fine, especially when the relationship is newer. For others, leaving a doctor of fifteen years is not something they will do.

The second is to change plans during the Annual Enrollment Period, choosing one whose network includes the doctors you want to keep. Then the new plan's drug list and costs need the same careful look, since the whole plan changes, not just the network.

Yes, and it is a trade-off, not a recommendation. Medicare Advantage is network-based: the plan contracts with a set of doctors and hospitals, and that set can change each year.

Original Medicare is not network-based, so you can generally see any provider who accepts Medicare. Many people pair it with a Medigap supplement policy and a separate drug plan, so a renegotiated contract does not move their doctors in and out.

That freedom carries its own trade-offs: a different cost structure, drug coverage arranged separately, and medical underwriting that may apply if you buy a Medigap policy later rather than when you first became eligible. I will not tell you to drop one or keep the other; that depends on the person.

The main window is the Annual Enrollment Period, October 15 through December 7. What you decide then takes effect January 1.

There is one more. If you are in a Medicare Advantage plan on January 1, you have until March 31 to make one change. It is a second chance, not a replacement for doing the work in the fall.

That is why I ask people to read the letter in September: it gives you a full month before the window opens. Deciding in early December, against a deadline, is harder.

Keep it. Put it in a folder with your Medicare card, plan card, and medication list, where you will find it again in October.

Then bring the folder to a consultation. We will read the letter line by line in Korean, and I will check, one by one, whether the doctors and hospitals you go to are in the plan's network next year and whether your medications are covered.
