The Medicare Annual Notice of Change 2027 outlines the specific adjustments to your plan’s costs and coverage effective January 1. It is important to note that your premium, drug copays, provider network, and pharmacy options may undergo changes, regardless of any actions taken on your part or the stability of your health status.

The good news is that you still have time. Medicare’s Open Enrollment Period runs from October 15 to December 7. This guide explains what the notice is, what to look for, and how to decide whether to keep your plan or switch.
What Is the Medicare Annual Notice of Change?
The Annual Notice of Change, often shortened to ANOC, is a yearly letter from your Medicare Advantage plan or Medicare Part D prescription drug plan. It lists every change coming to your plan next year.
Plans are generally required to send it by the end of September. Many also send a second document called the Evidence of Coverage, which explains the plan’s rules in full detail.
Here is what the ANOC usually covers:
- Changes to your monthly premium
- Changes to your deductible
- Copays and coinsurance for doctor visits, specialists, and hospital stays
- Changes to the drug formulary (the list of covered medications)
- Changes to your provider network
- Updates to extra benefits such as dental, vision, or hearing
If you have Original Medicare with a Medigap policy only, you will not get an ANOC from Medicare itself. But if you also have a separate Part D plan, that plan will send you one.
Why the 2027 Notice Deserves Extra Attention
Every ANOC matters. This year, there is one more reason to read yours closely.
According to CMS, the standard Part D deductible is rising from $615 in 2026 to $700 in 2027. The annual out-of-pocket cap on covered Part D drugs is also rising, from $2,100 to $2,400.
These are the maximum amounts under the standard benefit design. Individual plans may charge less. Some have no deductible at all. That is exactly why your own notice matters more than the headline numbers.
A few other points to keep in mind:
- Your plan’s premium for 2027 may be higher, lower, or unchanged.
- Your medications may move to a different cost tier.
- A drug you take may need prior approval or have new restrictions.
- Some plans leave certain counties or stop operating altogether.
As of mid-October 2026, the 2027 Medicare Part B premium had not been finalized. Check Medicare.gov for the official figure once it is announced, and be careful with websites that present an unofficial number as final.
Important Dates to Remember
Mark these on your calendar:
- October 15 to December 7: Medicare Open Enrollment (Annual Enrollment Period). You can switch Medicare Advantage plans, move between Original Medicare and Medicare Advantage, and join, drop, or change a Part D plan.
- January 1: New coverage and new costs begin.
- January 1 to March 31: Medicare Advantage Open Enrollment. If you are already in a Medicare Advantage plan, you can make one change during this window. It is not a second chance to shop freely, so it is better to decide before December 7.
Step-by-Step: How to Review Your Annual Notice of Change
You do not need to be a Medicare expert. Go through the notice in this order.
Step 1: Gather Your Documents
Set out these items on the kitchen table:
- Your Annual Notice of Change
- Your current Medicare card and plan card
- A list of every medication you take, including dose and how often
- Your pharmacy name
- A list of your doctors and specialists
Step 2: Check the Monthly Premium
Find the premium line first. Compare the 2026 amount with the 2027 amount. Remember that this is only one part of your yearly cost.
Step 3: Look at the Deductible and Out-of-Pocket Limit
Many people skip this part. A low premium can come with a higher deductible. Look at what you will pay before the plan starts sharing costs, and what the maximum yearly spending limit is.
Step 4: Check Every Medication on Your List
Look at the formulary section. For each drug, confirm:
- Is it still covered?
- Has it moved to a higher tier?
- Are there new rules like step therapy or prior authorization?
- Is your pharmacy still in the plan’s preferred network?
Step 5: Confirm Your Doctors and Hospitals Are In-Network
Networks can change. Call your doctor’s office and ask whether they will accept your plan in 2027. Do not rely only on last year’s information.
Step 6: Review Extra Benefits
If you chose your plan for dental, vision, hearing, or fitness benefits, check that they are still included and whether the limits have changed.
Step 7: Compare Plans Using the Official Tool
Use the Medicare Plan Finder on Medicare.gov. Enter your medications and pharmacy to see estimated total yearly costs for each plan. Compare your current plan against at least two others before deciding.
Real-Life Examples
These are general examples to show how small changes can add up.
Example 1: The premium looked fine, the drug cost did not. A retiree sees that her monthly premium stays the same and assumes nothing has changed. Later she finds that her main prescription moved to a higher tier. Her yearly drug costs would have been noticeably higher. Checking the formulary section would have caught it.
Example 2: The doctor left the network. A retired teacher has seen the same cardiologist for years. His plan’s notice shows that the cardiologist’s group is no longer in-network for 2027. A quick phone call confirms it. He now has time to compare plans that include his doctor.
Example 3: Staying put was the right choice. A couple reviews their notice, checks their medications, and confirms their doctors are covered. Costs are close to last year’s. They keep their plan, knowing it was an informed decision rather than an automatic one.
Common Reasons Plan Costs and Coverage Change
If your costs look different, it usually comes down to one of these:
- Federal rule updates. Part D deductible and out-of-pocket limits are updated each year under a set formula.
- Insurer pricing decisions. Plans review their costs and adjust premiums and copays.
- Formulary updates. Plans add, remove, or move drugs between tiers.
- Network contracts. Agreements between insurers and providers can end or change.
- Plan service area changes. A plan may reduce or end coverage in some counties.
None of this means something is wrong. It simply means the plan you chose last year may not be the best fit this year.
Do’s and Don’ts During Open Enrollment
Do
- Read your notice as soon as it arrives
- Compare at least two or three plans
- Use your actual medication list, not a rough memory of it
- Confirm your doctors and pharmacy
- Write down the date and details of any call you make
- Ask a trusted family member to review your choices with you
Don’t
- Don’t ignore the notice because you are happy with your plan
- Don’t choose based on premium alone
- Don’t wait until the last week of November
- Don’t share your Medicare number with anyone who contacts you unexpectedly
- Don’t feel pressured to decide on a single phone call
Common Mistakes Seniors Make With the Annual Notice
- Assuming nothing has changed. Plans change every year, even when the plan name stays the same.
- Focusing only on the monthly premium. Deductibles, copays, and drug costs often matter more.
- Not updating the drug list. If you started a new medication this year, add it before comparing.
- Skipping the network check. A plan is only useful if your doctors accept it.
- Waiting too long. Last-minute decisions are rushed decisions.
- Trusting unsolicited calls. Real plan changes should come from you checking official tools, not from someone who calls you first.
Stay Alert for Medicare Open Enrollment Scams
Open enrollment season is also a busy season for scammers. They may pretend to be from Medicare and say your card is expiring or that you must act immediately.
Keep these points in mind:
- Medicare does not call you out of the blue to sell you a plan or ask for your Medicare number.
- No one can charge you a fee for a new Medicare card.
- Be careful with callers who create urgency or ask for payment by gift card or wire transfer.

Prevention Tips for Next Year
A little routine makes this easier every fall:
- Keep your medication list updated all year
- Save your plan documents in one folder
- Set a calendar reminder for October 1 to look for your notice
- Review your plan every year, even if you stay with it
- Tell a family member where your Medicare documents are kept
When to Contact Medicare or a Counselor
