Your 2027 Medicare Annual Notice of Change Is Coming: How to Read It Before Annual Enrollment (October 15 to December 7)
Every fall, your Medicare plan mails you one document that matters more than any headline: your Medicare Annual Notice of Change, often just called the ANOC. For 2027 coverage, plans must get it to you by September 30, 2026, and the Annual Enrollment Period when you can actually make changes runs October 15 to December 7, 2026. Reading your ANOC early is the single best way to avoid a January surprise in your premium, your drug costs, or your doctor network. Here is what the notice is, what is changing across Medicare in 2027, and what (if anything) you need to do.
What the Medicare Annual Notice of Change actually is
The ANOC is a required document your Medicare Advantage or Medicare Part D plan must send so that you receive it no later than September 30, which means by September 30, 2026 for the 2027 plan year. That is about two weeks before Annual Enrollment opens on October 15. You can read more about the notice on Medicare's official Annual Notice of Change page. It arrives alongside a companion booklet called the Evidence of Coverage, and together they spell out exactly how your plan is changing for the coming year.
The important thing to understand is that the ANOC is personal. National news can tell you what is happening to Medicare in general, but only your ANOC tells you what is happening to your plan: your monthly premium, your deductible, your copays, your drug list, your pharmacy and provider network, your out-of-pocket maximum, and whether your plan will even be offered in 2027. Yet according to the Kaiser Family Foundation (KFF), nearly 7 in 10 (69%) of Medicare beneficiaries did not compare their coverage options during a recent enrollment period. The ANOC is the document that makes comparing easy, and most people leave it in the envelope.
If you are on a Medicare Advantage (MAPD) plan or a standalone Part D drug plan, this notice applies to you. (If you have a Medicare Supplement, or Medigap, policy, your standardized benefits work differently, though any separate Part D drug plan you carry will still send its own ANOC.)
What to look for when you open it
You do not need to be an expert to read your ANOC well. Set aside fifteen quiet minutes, put last year's plan details next to it, and check these lines against what you have now:
- Monthly premium. Is it going up, down, or staying the same?
- Annual deductible. What you pay before the plan starts sharing costs.
- Copays and coinsurance. For primary care, specialists, hospital stays, and lab work.
- Drug formulary and tiers. This is the big one. Is a medication you take moving to a higher tier, or leaving the list altogether?
- Pharmacy and provider network. Are your doctors and your pharmacy still in network for 2027?
- Out-of-pocket maximum. The most the plan can ask you to pay in a year.
- Supplemental benefits. Dental, vision, hearing, over-the-counter allowances, meals, and transportation can all shift year to year.
- Whether the plan continues. The notice will say if your plan is not being offered in 2027.
If your ANOC tells you the plan will not be offered next year, do not panic. Different rules and a special enrollment period apply in that situation, and it is a short conversation we are glad to walk you through separately.
What is changing across Medicare in 2027
Your ANOC shows your plan's specific changes. Behind those are a few Medicare-wide changes for 2027 that are worth understanding, because they help explain what you are reading.
Part D drug costs are stepping up
The prescription drug benefit continues the structure that began in 2025: there is no coverage gap (the old "donut hole"), the benefit runs in three phases, and once you reach the catastrophic phase you pay nothing more for covered drugs that year, as the law firm Crowell & Moring summarizes in its analysis of the 2027 rule. The dollar figures, however, are indexed upward each year. For 2027, CMS's finalized Part D parameters raise the standard deductible and the annual out-of-pocket cap:
| Standard Part D cost | 2026 | 2027 |
|---|---|---|
| Annual deductible | $615 | about $700 |
| Yearly out-of-pocket cap on drug spending | $2,100 | $2,400 |
One point of reassurance and accuracy: the yearly out-of-pocket cap is the same protection that started at $2,000 in 2025 (rising to $2,100 in 2026, as KFF documents in its Part D snapshot), simply indexed upward to $2,400 for 2027. It is not a new or separate cap, and it still means there is now a firm ceiling on what you pay out of pocket for covered prescriptions in a year.
A second round of negotiated drug prices begins
January 1, 2027 brings a second, larger round of Medicare-negotiated drug prices, covering 15 Part D drugs (including the popular GLP-1 medications Ozempic and Wegovy). The first round of 10 drugs took effect back in 2026, so this is a continuation rather than a start, per KFF. The savings are real, but for most individuals they are modest, and the $2,400 annual cap already limits what any one person pays. If you take one of the affected medications, your ANOC and drug list will show how it plays out for you.
Medicare Advantage benefits keep shifting
Here is the trend that makes reading your ANOC so worthwhile. Even though Medicare finalized a net average payment increase of 2.48% (over $13 billion) to Medicare Advantage plans for 2027, higher than the 0.09% first proposed, as the firm Bass, Berry & Sims reports, many plans are still trimming extra benefits or raising cost-sharing. In other words, "Medicare Advantage is being gutted" is too simple a story, and so is "plans got a raise, so nothing will change." Both miss the point: what happens to your benefits is a plan-by-plan decision that only your ANOC reveals.
The direction of travel is visible in the numbers. Nationally, the average supplemental premium edged up to about $15 a month in 2026, the average in-network out-of-pocket maximum reached $5,421, and several extra benefits were offered to fewer enrollees than the year before:
| Supplemental benefit | 2025 | 2026 |
|---|---|---|
| Over-the-counter allowance | 79% | 68% |
| Meal benefits | 70% | 65% |
| Transportation | 28% | 22% |
Those are national figures from KFF's review of Medicare Advantage in 2026, not a forecast for your plan. Your ANOC is where you see whether an extra benefit you count on is staying, shrinking, or going away.
A quick word on star ratings
CMS also reworked plan quality star ratings for 2027, removing 11 measures, according to the policy firm Applied Policy. For accuracy, one detail matters: some newer quality measures, such as a new depression screening measure, are being phased in for future ratings and first appear in the 2029 Star Ratings. They will not change the star rating you see when you choose a 2027 plan this fall.
Your action window: October 15 to December 7, 2026
Once you have read your ANOC, the time to act is the Annual Enrollment Period, which runs October 15 through December 7, 2026, according to KFF. Any change you make during that window takes effect January 1, 2027.
If your ANOC shows changes you do not like, this is your chance to switch to a plan that fits better. If your plan still suits you, you do not have to do anything at all, and your coverage simply continues. The goal is not to switch for the sake of switching. The goal is to make a decision on purpose rather than by default.
Frequently asked questions
When will my Medicare Annual Notice of Change arrive?
Your plan must send it so you receive it no later than September 30, which is September 30, 2026 for the 2027 plan year, about two weeks before Annual Enrollment opens on October 15. If you have not seen yours by early October, call your plan, because the changes it describes take effect January 1.
When is the Medicare Annual Enrollment Period for 2027 coverage?
It runs October 15 to December 7, 2026. Elections you make during that window take effect January 1, 2027. This is the main yearly window for changing Medicare Advantage and Part D plans.
What is changing with Medicare Advantage in 2027?
Medicare-wide, the standard Part D deductible rises to about $700 and the annual out-of-pocket drug cap rises to $2,400, a second round of negotiated drug prices begins, and quality star ratings were reworked. Plan by plan, your premium, deductible, drug list, network, and extra benefits may all change, and only your ANOC shows those specifics.
Do I have to do anything during Annual Enrollment?
Not necessarily. If your plan continues and still fits your doctors, medications, and budget, you can stay and do nothing. But you should still read your ANOC, because a quiet change to a drug tier or a network can cost you real money if you find out in January instead of October.
