Medicare Annual Notice of Change Checklist: What Wisconsin Beneficiaries Should Review Before AEP

Your Medicare plan can change from one year to the next, even when you are happy with the coverage you have today. The Annual Notice of Change is the document that explains those updates before the next plan year begins. I encourage every Medicare beneficiary to review it carefully before the Annual Enrollment Period ends.

At Red Sky Insurance Advisors, I help people make sense of Medicare changes without pressure or a one-size-fits-all recommendation. A free annual plan review can help you understand what is changing, confirm whether your current coverage still fits, and decide whether any action is appropriate.

What Is the Medicare Annual Notice of Change?

The Annual Notice of Change, often called the ANOC, is a letter or booklet sent by Medicare Advantage and Medicare Part D prescription drug plans each fall. It outlines changes that will take effect on January 1 of the coming year.

This is not usually a bill, cancellation notice, or a reason to panic. It is a plan-specific summary of what may be different in your benefits, costs, provider access, prescription coverage, and plan rules. If you have a Medicare Advantage plan, you should receive an ANOC from that plan. If you have a standalone Part D prescription drug plan with Original Medicare and a Medicare supplement policy, you should receive an ANOC from the Part D plan.

Your Medicare supplement policy, also called Medigap in Wisconsin and elsewhere, is different. It generally does not send the same Medicare Annual Notice of Change document, but its premium may still change. That is one reason I recommend looking at your complete Medicare coverage rather than reviewing only one piece of it.

When Does the Notice Typically Arrive?

Most plans mail the Annual Notice of Change by the end of September. If you receive plan materials electronically, you may receive an email telling you that the notice is available online instead. Either way, do not set it aside with the rest of the mail.

The timing is important because Medicare open enrollment, formally known as the Annual Enrollment Period, runs from October 15 through December 7. During that period, eligible beneficiaries can make certain changes to Medicare Advantage and Part D drug coverage that take effect January 1.

I suggest opening the notice as soon as it arrives and marking any changes that affect your doctors, medications, budget, or preferred pharmacy. That gives you time to compare Medicare plans in Wisconsin thoughtfully rather than making a rushed decision near the deadline.

Start With Premiums, Deductibles, and Copays

Costs are often the first changes people notice, and for good reason. Review your monthly premium for the coming year, including the premium for a Medicare Advantage plan, Part D plan, or Medicare supplement policy if you have one. A plan with a familiar name or a premium that worked last year may look different next year.

Then compare the deductible and the copays or coinsurance you would pay when receiving care. Pay close attention to the services you use most often, such as primary care visits, specialist appointments, urgent care, lab work, imaging, outpatient surgery, hospital stays, and skilled nursing care. For Part D coverage, look at the prescription drug deductible as well as the cost-sharing for each medication tier.

A lower premium does not automatically mean lower overall costs. Likewise, a premium increase does not automatically mean you need to leave your plan. The goal is to understand how the full cost structure could affect you based on the care and prescriptions you expect to use.

Confirm Your Doctors and Provider Network

If you have a Medicare Advantage plan, provider networks deserve careful attention. A physician, clinic, hospital, or specialist you saw this year may not be in-network next year, and plan network rules can vary. That can be especially meaningful for people who receive care through Madison-area health systems or see specialists in Dane County.

Review the network information in your notice, but do not rely only on a general statement that the network is changing. I recommend verifying your specific primary care provider, specialists, preferred hospitals, and any facilities where you receive recurring services. Ask whether they will participate in the exact plan option you are considering for the new plan year.

For clients with Medicare supplement coverage, provider-network questions work differently because these policies are used with Original Medicare. Even so, it is still wise to confirm that the providers you want to see accept Medicare assignment and understand how your coverage works.

Review Pharmacies and Your Drug Formulary

Prescription coverage is one of the most important reasons to complete a Medicare annual plan review in Wisconsin. Part D plans and Medicare Advantage plans with drug coverage can change their formularies, drug tiers, utilization rules, preferred pharmacies, and pharmacy networks each year.

Start by making a current medication list. Include the exact drug name, dosage, frequency, and whether you use a retail or mail-order pharmacy. Then check whether each medication remains on the plan formulary, whether its tier is changing, and whether the plan has updated the cost-sharing amount. A medication can remain covered but move to a different tier, which may affect what you pay.

Also check your pharmacy. A pharmacy that was preferred this year may not be preferred next year, and that difference can affect drug costs. For Fitchburg, Madison, and Dane County residents, a convenient pharmacy is important, but it is worth confirming whether it is in-network and whether another in-network option has different cost-sharing.

Watch for Prior Authorization and Other Plan Rules

Prior authorization means a plan may require approval before covering certain services, procedures, equipment, or medications. Your Annual Notice of Change may identify new or revised prior authorization requirements. These rules can matter if you use specialty medications, durable medical equipment, outpatient therapies, advanced imaging, or ongoing medical treatment.

Look for changes involving referrals, step therapy, quantity limits, coverage criteria, and network restrictions. If you have a treatment planned for early in the new year, it can be helpful to ask the plan or your provider how the upcoming rules may apply. Understanding these details in advance can reduce unwelcome surprises later.

Do Not Overlook Supplemental Benefits

Many Medicare Advantage plans include supplemental benefits beyond Original Medicare, such as dental, vision, hearing, over-the-counter allowances, fitness programs, transportation, meal support, or other wellness-related benefits. These extras can be useful, but they may change in value, availability, service area, provider participation, or usage rules from year to year.

Review the details rather than focusing only on a benefit headline. For example, dental coverage may have a maximum benefit amount, a network requirement, waiting rules, or limits on covered services. Hearing and vision benefits may use specific providers or allowances. If supplemental benefits are important to you, I can help you compare how the details fit your actual needs.

Why Review Your Plan Even If You Are Satisfied?

Being satisfied with your current plan is a good thing. It does not mean you should assume it will remain the same. Medicare plans can change their costs, provider networks, pharmacies, drug formularies, prior authorization rules, and supplemental benefits from one plan year to the next.

Your own needs can change, too. A new prescription, a doctor referral, a move within Wisconsin, a change in preferred pharmacy, or a different budget can all affect whether your current coverage remains a good fit. Reviewing your ANOC does not obligate you to change plans. It simply helps you make an informed decision before the Medicare Annual Enrollment Period closes on December 7.

How an Independent Medicare Broker Can Help

As an independent Medicare broker serving Fitchburg, Madison, Dane County, and Wisconsin, I can help you review your current coverage and compare the changes that matter most to you. My role is to explain options clearly, answer questions, and help you evaluate available Medicare Advantage, Medicare supplement, and Part D prescription drug coverage based on your individual circumstances.

There is no fee and no pressure for an annual review with me. I do not believe a plan should be selected because of a carrier name, an advertisement, or a benefit that sounds appealing without the details. I believe you deserve time, clarity, and straightforward Medicare guidance.

FAQ

Do I have to change my Medicare plan after receiving an ANOC?

No. Receiving an Annual Notice of Change does not mean you must change plans. If you do nothing, your plan will generally renew for the next year, provided it remains available. Still, I recommend reviewing the notice so you understand the coverage and cost changes that will apply January 1.

When is Medicare open enrollment in Wisconsin?

For most Medicare beneficiaries, the Annual Enrollment Period runs from October 15 through December 7 each year. Changes made during that window generally become effective on January 1 of the following year.

What should I bring to an annual Medicare plan review?

Bring your Annual Notice of Change, current insurance cards, a complete medication list with dosages, and the names of your doctors, specialists, hospitals, and preferred pharmacies. It is also helpful to note any changes in your health needs or budget.

Can I review a Medicare supplement and Part D plan at the same time?

Yes. If you have Original Medicare with a Medicare supplement policy and a standalone Part D plan, I can help you review the pieces together. Part D changes are especially important because formularies, tiers, pharmacies, and plan costs may change annually.
