ANOC Medicare: How to Read Your 2027 Annual Notice of Change
The ANOC Medicare notice arrives each September from your Medicare Advantage or Part D plan.
Inside is your Annual Notice of Change for 2027, often called the ANOC.
It is easy to set aside. That can be an expensive mistake.
Start Here: The Cost Comparison Page
One of the first sections to find is usually called something similar to:
Summary of Important Costs for 2027
Look for two columns comparing:
2026: This Year
2027: Next Year
This section can show changes to:
Monthly plan premium
Deductible
Maximum out-of-pocket amount
Primary care visits
Specialist visits
Inpatient hospital stays
Read this section left to right, not front to back.
For example, a $0 monthly plan premium could become $29. A $30 specialist copay could become $50. Your maximum out-of-pocket limit could increase by several hundred dollars.
Those are examples, but they show why the comparison matters.
A plan can have the same name, look familiar, and still work differently next year.
Start with the costs and services you actually use.
What Is an ANOC in Medicare?
ANOC stands for Annual Notice of Change.
It shows what is changing in your Medicare plan for the next calendar year. Those changes generally take effect January 1.
The ANOC is a summary of what is changing, not the full details of your plan.
Your Evidence of Coverage, or EOC, provides the more detailed explanation of your benefits, costs, coverage rules, and member rights.
If you have a Medicare Advantage plan or a stand-alone Part D prescription drug plan, the ANOC is one of the most useful documents you receive each year.
When Should You Receive Your 2027 ANOC?
Medicare plans send the Annual Notice of Change each fall.
Your plan should send your ANOC by September 30. This gives you time to review what is changing before the Medicare Annual Enrollment Period begins.
Date | What It Means |
|---|---|
By September 30, 2026 | 2027 ANOC sent by carrier in September |
Around October 1, 2026 | Begin comparing your current coverage with 2027 Medicare plan options |
October 15 through December 7, 2026 | Annual Enrollment Period |
January 1, 2027 | New plan costs, benefits, and coverage changes take effect |
If September ends and you have not received your ANOC, contact your plan.
Do not assume that because you did not receive a notice, nothing changed.
6 Things to Check in Your Medicare ANOC
Start with the areas that can have the biggest effect on your healthcare and your wallet.
1. Has Your Monthly Premium Changed?
Start with the monthly plan premium.
The ANOC compares what you are paying this year with what you will pay next year.
But do not stop there.
Most Medicare Advantage members also continue paying their Medicare Part B premium.
Some Medicare Advantage plans provide a reduction toward the Part B premium. This is sometimes advertised as a Part B giveback.
If your plan offers one, compare the 2026 amount with the 2027 amount.
Write down:
Your 2027 plan premium
Your Medicare Part B premium
Any Part B premium reduction provided by the plan
A plan premium staying at $0 does not automatically mean your overall costs stayed the same.
2. Has Your Maximum Out-of-Pocket Limit Changed?
This is one of the most overlooked numbers in a Medicare Advantage plan.
Your maximum out-of-pocket amount, often called the MOOP, limits how much you pay for covered medical services that count toward the plan’s limit during the calendar year.
Once you reach the applicable limit, you generally pay nothing for covered Part A and Part B services for the remainder of the calendar year.
A higher MOOP does not mean you will spend that amount.
It shows how much financial exposure you could have in a year when you need a lot of medical care.
That matters.
Someone who sees their doctor twice a year may barely notice a change.
Someone going through surgery, rehabilitation, cancer treatment, or several specialist visits may care a lot more.
3. Are Your Doctors and Hospitals Still in the Network?
Do not skip this section.
Your ANOC may tell you that the provider network is changing, but it may not list every doctor or hospital affected.
If the provider network is changing, check the 2027 Provider Directory and confirm the doctors, hospitals, and facilities you actually use.
Check:
Primary care doctor
Cardiologist
Orthopedist
Oncologist
Hospital
Outpatient surgery center
Imaging center
Infusion or treatment facility
Do not assume that because your doctor accepts your plan in 2026, the doctor will still participate in 2027.
Your primary care doctor could remain in network while a specialist, hospital, or treatment center you use leaves.
If you have an HMO, routine out-of-network care generally is not covered except in certain situations, such as emergencies or care authorized by the plan.
If you have a PPO, you may have out-of-network coverage, but the cost can be considerably different.
When a provider matters to you, check the 2027 network, not the card sitting in your wallet today.
4. Have Your Copays or Medical Benefits Changed?
The first cost comparison gives you the big numbers.
The later pages are where you may find the details.
Look for changes such as:
Benefits being added
Benefits being removed
Changes in copays or coinsurance
New benefit limits
Changes to prior authorization requirements
Referral requirements
Step therapy requirements for certain Part B drugs
Focus on the services you use.
A $10 increase in a specialist copay may not seem like much until you see several specialists throughout the year.
A change to hospital cost sharing can matter much more.
A new prior authorization requirement can also matter even when the copay did not change.
Do not judge your plan only by the benefits advertised.
Compare it based on how you actually use healthcare.
5. Have Your Extra Benefits Changed?
Medicare Advantage plans may include benefits such as:
Dental
Vision
Hearing
Over-the-counter benefits
Fitness benefits
Transportation
Other supplemental benefits
Do not stop when you see that a benefit is still included.
Look at how much you get and how the benefit works.
For example, a dental allowance could decrease even though dental coverage is still listed as a benefit.
The name of the benefit may stay the same while the amount, network, limits, or rules change.
If you used the benefit in 2026, look closely at what you will actually have in 2027.
6. Have Your Prescription Drugs or Part D Costs Changed?
If your Medicare Advantage plan includes Part D prescription drug coverage, or you have a stand-alone Part D plan, review your medications separately.
Use your actual medication list.
Check each prescription:
Is the drug still covered?
Did it move to a different formulary tier?
Is prior authorization required?
Is there a step therapy requirement?
Is there a quantity limit?
Is your pharmacy still preferred?
Did the plan’s drug deductible change?
There are also important Medicare Part D changes for 2027.
The standard Part D deductible increases from $615 in 2026 to $700 in 2027.
The Part D annual out-of-pocket threshold increases from $2,100 in 2026 to $2,400 in 2027.
The $2,400 out-of-pocket threshold does not mean your prescription costs stay the same as last year.
Your drug costs before reaching the threshold can still change based on the plan, formulary tier, pharmacy, and coverage rules.
Use your medication list, not your memory.
What Happens If You Do Nothing?
If your plan is continuing into 2027 and you want to stay in it, you generally do not need to re-enroll.
Your coverage will typically continue into the new year.
That does not mean nothing changed.
Doing nothing is still a decision.
Your plan may renew automatically while the premium, copays, maximum out-of-pocket limit, network, or benefits change.
The question is not simply:
Do I like my current plan?
A better question is:
Do I still like what this plan becomes on January 1?
What If Your Medicare Plan Is Ending?
A plan that will no longer be available is different from a normal year-to-year benefit change.
Plans can also change names, consolidate, or move members into another renewing plan.
If the first page of your notice says your plan is ending, leaving Medicare, or will no longer be offered in your area, do not treat it like a routine ANOC.
Read the notice carefully and pay close attention to the dates and options it gives you.
Do not assume your current card will simply continue working in January.
If your plan is ending, you may qualify for a Special Enrollment Period that gives you additional time to choose other Medicare coverage.
If you have Medicare Advantage and switch back to Original Medicare because your plan is leaving Medicare or no longer serving your area, you may also have a guaranteed-issue right to buy certain Medigap policies. Those rights are time-sensitive and depend on your specific situation.
This is one section of the notice you do not want to skim.
ANOC vs. Evidence of Coverage
These two documents do different jobs.
Your ANOC
The Annual Notice of Change tells you what is changing from this year to next year.
Your Evidence of Coverage
The Evidence of Coverage tells you how the plan works.
The EOC is the more detailed document. It explains your benefits, costs, coverage rules, rights, appeals, and responsibilities.
Use the ANOC to identify the change.
Use the Evidence of Coverage when you need the details.
What Should You Do After You Receive Your ANOC?
Compare your 2026 and 2027 costs.
Check your doctors, specialists, and hospitals.
Review your prescriptions and pharmacy if you have Part D coverage.
Review the benefits you actually use.
Make a note of anything that changed.
Call the agent who helped you enroll and complete an annual review. If you can’t reach them, call us at 972-544-6509.
Starting October 1, compare your current coverage with the 2027 options available in your area.
The Medicare Annual Enrollment Period runs from October 15 through December 7 each year.
Do You Need to Change Medicare Plans Because Your ANOC Changed?
Not necessarily.
The fact that something changed does not automatically mean you should change plans.
What matters is whether the change affects you.
If a benefit you never use changes, it may have little impact.
If a specialist copay increases by $5 and you see that doctor twice a year, the difference may be small.
If your oncologist leaves the network, your hospital costs increase substantially, or one of your expensive prescriptions moves to a different coverage tier, that deserves a closer look.
The reason to read your ANOC is not to find a reason to switch.
It is to understand what you will have on January 1 if you stay where you are.
Frequently Asked Questions About Medicare ANOC Notices
What does ANOC mean in Medicare?
ANOC stands for Annual Notice of Change. It explains what is changing in your Medicare plan for the upcoming calendar year.
When should I receive my 2027 Medicare ANOC?
Your plan should send your ANOC by September 30.
What should I do if I have not received my ANOC?
Contact your Medicare plan and request a copy.
Does Original Medicare send an ANOC?

Can I change Medicare plans after reviewing my ANOC?
Yes. The Medicare Annual Enrollment Period runs from October 15 through December 7 each year.
During this period, you can make certain changes to Medicare Advantage and Part D coverage.
If I like my Medicare plan, do I have to re-enroll?
Usually not, as long as your plan is continuing and you remain eligible for it.
That does not mean you should skip the ANOC.
Review your 2027 plan changes before deciding to leave your coverage unchanged.

Confirm your doctors, hospitals, and prescriptions: Networks and drug coverage can change from one year to the next.
Doing nothing is still a decision: Your plan may renew automatically, but the costs, benefits, and coverage can still change on January 1.
THIS WEEK’S ACTION STEP
When your ANOC arrives in the mail, don’t trash it. Review it, then call your agent with any questions.
Fun Fact
The Moon is slowly moving away from Earth at about 1.5 inches per year.
Basically, the Moon is saying, “Later, Earth. I’m out of here.”
And in roughly 600 to 700 million years, it will be far enough away that we will no longer have total solar eclipses on Earth. We will still get eclipses, but the Moon will be too small in the sky to completely cover the Sun.
So go ahead and mark your calendar.
Have a blessed week!
