What the ANOC Actually Is
If you’re enrolled in a Medicare Advantage or Part D plan, your carrier is required to send you an Annual Notice of Change every September. It’s a plan-specific letter — not a generic Medicare mailing — that lays out exactly what will be different about your coverage starting January 1. Of everything that lands in your mailbox during AEP season, this is the one document worth reading in full.
Why It Matters More Than General AEP News
Articles about industry-wide trends for the coming plan year are useful for context, but your ANOC tells you what’s actually changing for the plan you’re on. Two people enrolled in different plans from the same carrier can see very different changes in their ANOC letters. Skipping it and relying on general AEP coverage means you might miss something specific to your situation.
What to Look For, Section by Section
Premium and Deductible Changes. Compare this year’s numbers to what you’re paying now. Even a modest premium increase adds up over twelve months.
Provider Network Changes. Some plans note if certain hospital systems or specialist groups are leaving the network. If your ANOC mentions network changes and you don’t see your doctor’s name specifically addressed, it’s worth calling the plan directly to confirm.
Formulary Changes. Look for changes to your specific medications — tier movement, new prior authorization requirements, or a drug being dropped from the formulary altogether. This is one of the most common reasons people end up switching plans. Our guide on Part D drug coverage changes for Plan Year 2027 walks through this in more depth.
Extra Benefits. Dental, vision, hearing, and OTC allowances are popular add-ons for Medicare Advantage plans, but they aren’t guaranteed to stay the same. Check whether the amounts or coverage levels are shrinking, growing, or disappearing.
Out-of-Pocket Maximum. This is your ceiling for the year on covered services. If it’s increasing significantly, that’s worth factoring into your decision even if your monthly premium isn’t changing.
What If You Don’t Receive an ANOC?
If you’re enrolled in Medicare Advantage or Part D and haven’t received your ANOC by early October, contact your plan directly. Don’t wait until the last week of AEP to track it down — you want time to actually digest what it says.
Turning the ANOC Into a Decision
Once you’ve read through your ANOC, you’re in a much better position to decide whether staying enrolled still makes sense or whether it’s worth comparing other plans. If the changes are minor and your plan still covers your doctors and medications well, sticking with it may be the right call. If the changes touch something that matters to you — a departing specialist, a medication moving tiers, a shrinking benefit — that’s your cue to start shopping.

Don’t Go It Alone
The ANOC is dense, and insurance language doesn’t always translate clearly into plain English. If you’re unsure what a particular change means for your coverage, a licensed agent can review the letter with you over the phone and help translate it into what it actually means for your care and your budget.
