Your ANOC Is Coming — Don't Throw It Away
Every September, Medicare Advantage (MAPD) and Part D prescription drug plan members receive a piece of mail that most people toss without reading. It's called the Annual Notice of Change, or ANOC — and it may be the most important piece of mail you get all year.
Here's what it is, what to look for, and why it deserves more than a glance before it hits the recycling bin.
What Is the ANOC?
The Annual Notice of Change is a federally required document that your Medicare Advantage or Part D plan must send you every year by September 30. It outlines every change your plan is making for the upcoming year — effective January 1.
Think of it as your plan's way of saying: "Here's what's different next year."
Those differences can be significant. Premiums, deductibles, copays, drug formularies, covered providers, and service areas can all change from one year to the next — and your plan is only required to tell you once, in this document.
Why It Matters More Than You Think
Most people assume their plan will stay roughly the same year to year. Sometimes it does. But often it doesn't — and the changes can catch people off guard in January when they're already at the pharmacy or the doctor's office.
Common changes you might find in your ANOC:
- Premium increases — your monthly cost goes up
- Deductible changes — what you pay before coverage kicks in
- Copay or coinsurance adjustments — what you pay per visit or service
- Drug formulary changes — a medication you take may move to a higher tier or be removed entirely
- Network changes — a doctor, specialist, or hospital may no longer be in-network
- Extra benefits added or removed — dental, vision, hearing, or fitness benefits may change
- Service area changes — in rare cases, a plan may stop serving your county
Any one of these changes could meaningfully affect your out-of-pocket costs or access to care next year.
When Does It Arrive?
Your ANOC will arrive in late September — plans are required to mail it by September 30. If you've opted into electronic delivery, you may receive it by email or through your plan's online portal instead.
Keep an eye out for it starting in mid-September. If you haven't received it by October 1, contact your plan directly to request a copy.
What to Do When It Arrives
Step 1: Open it. Seriously — don't set it aside. This one document tells you everything that's changing about your coverage.
Step 2: Check your medications. If you take prescription drugs, look up each one in the formulary section. Has anything moved to a higher tier? Has anything been removed? Drug costs are one of the most common and impactful changes people discover too late.
Step 3: Verify your doctors are still in-network. If you have a Medicare Advantage plan, confirm that your primary care doctor and any specialists you see regularly are still in the plan's network for next year.
Step 4: Review your costs. Compare your current premium, deductible, and copays to what the ANOC shows for next year. Even a modest increase in monthly premium adds up over 12 months.
Step 5: Decide if you need to act. If the changes are minor and your plan still works well for you, you may not need to do anything. But if something significant has changed — a key medication, a preferred doctor, or a major cost increase — you have options.
You Have Time to Make a Change
The ANOC arrives in September for a reason: it gives you time to review your options before Medicare Open Enrollment begins on October 15.
Open Enrollment runs from October 15 through December 7 each year. During this window, you can:
- Switch from one Medicare Advantage plan to another
- Switch from Medicare Advantage back to Original Medicare
- Join, switch, or drop a Part D prescription drug plan
Any changes you make during Open Enrollment take effect January 1 of the following year.
If your ANOC reveals changes that concern you, this is your window to act. Missing the December 7 deadline means you're locked into your current plan for another full year.
You Don't Have to Figure This Out Alone
Reading the ANOC can feel overwhelming — it's a dense document, and comparing it to other available plans takes time and knowledge of what to look for.
That's exactly what I do. Every fall, I sit down with my clients to review their ANOC, compare it against other plans available in their area, and help them decide whether to stay put or make a change. There's no cost for this review, and no pressure to switch.
If you'd like a second set of eyes on your ANOC when it arrives, give me a call. I'm based in Minnetrista, MN and work with Medicare clients across the area.
