7 Things You Must Check in Your ANOC Before the 2027 Medicare AEP

A practical review guide for Medicare Advantage and Part D plan members in New Jersey

New Jersey Case Study

Margaret Song, a 72-year-old resident of Bergen County, New Jersey, had been on the same Medicare Advantage plan for three years. Every fall, the Annual Enrollment Period came and went, and she thought, “Nothing went wrong last year, so why change anything?” She never opened her ANOC. Then in January 2026, she arrived at her primary care physician’s office in Fort Lee — a doctor she had seen for over a decade — only to be told that her plan no longer included him in its network. It took nearly two months to establish care with a new provider, and during that time, the management of her prescription medications was delayed. For New Jersey residents, where medical providers are plentiful, but plan networks shift significantly from year to year, Margaret’s story is a clear reminder of what one unchecked notice can cost.

Every fall, one of the most important windows in the Medicare calendar opens. The Annual Enrollment Period, or AEP, runs from October 15 through December 7 each year. During this time, you can switch, drop, or enroll in a Medicare Advantage or Part D prescription drug plan for the following year.

As 2027 approaches, one assumption you cannot afford to make is that your current plan will remain unchanged. Premiums, benefits, provider networks, and drug coverage are all subject to change in each plan year. The good news is that every plan is required to notify you of those changes in advance — through a document called ANOC.

What Is an ANOC and Why Does It Matter

ANOC stands for Annual Notice of Change. It is an official document sent by your Medicare Advantage or Part D plan that explains exactly how your coverage will change in the coming year. Plans are required to mail it to enrolled members by September 30 each year, and many plans also make it available through their member portal online.

When your ANOC arrives, do not file it away without reading it. The seven items below are the ones most likely to affect your health care costs and access in 2027 — and the ones most overlooked.

01 Review Your Monthly Premium

A low premium today does not guarantee a low premium next year

Even if your current plan charges little or nothing in monthly premiums, that figure can change. Many Medicare Advantage plans adjust premiums annually in response to changes in their cost structure or the benefits they offer. Your ANOC will show you exactly what your premium will be in 2027.

The key is not to look at the premium in isolation. A plan that raises its monthly premium by $25 but lowers its specialist copays could cost you less overall if you see specialists regularly. Conversely, a plan with no premium increase but a higher deductible could end up costing more. Always weigh the premium against the full picture of cost-sharing before drawing any conclusions.

02 Check Changes to Your Deductible and Cost-Sharing

Small changes in copays add up to hundreds of dollars over a year

Your deductible is the amount you pay out of pocket before your plan begins covering services. Your copays and coinsurance are the fixed or percentage-based amounts you pay each time you use a covered service. Both of these figures can change from one plan year to the next, and your ANOC will detail any adjustments.

For people who use medical services frequently, the cumulative effect of seemingly small changes can be significant. If your specialist visit copay increases from $40 to $55 and you see a specialist twice a month, that is an additional $360 per year — before accounting for any other changes. In a state like New Jersey, where health care costs tend to run higher than the national average, these differences carry even more weight.

03 Verify Your Maximum Out-of-Pocket Limit

This is your financial ceiling for unexpected medical events

The Maximum Out-of-Pocket limit is one of the most important protections in a Medicare Advantage plan and one that does not exist in Original Medicare. Once you reach this limit in a given calendar year, your plan covers 100 percent of the cost for all covered services for the remainder of the year.

Check whether this MOOP has changed in your 2027 ANOC. If the limit has risen substantially, you may be exposed to significantly higher costs in the event of serious illness, surgery, or extended hospital stay. For anyone managing a chronic condition or anticipating a major procedure, this number deserves close attention. Comparing this figure across available plans in your area can reveal meaningful differences in financial protection.

04 Confirm That Your Doctors and Hospitals Are Still In-Network

Provider networks change every year — verify before assuming

Plan provider networks are renegotiated annually, which means a doctor or hospital that was in-network in 2026 may not be in-network in 2027. This is precisely what happened to Margaret in Bergen County, and it is one of the most disruptive changes a Medicare plan member can encounter.

Before the 2027 plan year begins, confirm that your primary care physician, specialists, and any hospitals or outpatient facilities you rely on are still included in your plan’s network. New Jersey’s medical landscape spans multiple county health systems — from RWJBarnabas Health and Hackensack Meridian Health to Atlantic Health System — and different plans cover different networks. Use your plan’s online provider directory, or call the plan directly, to verify each provider by name. Do not rely on directory listings from the prior year, as they may not reflect current contracts.

Pay special attention if you have a preferred specialist or hospital system

If you receive ongoing care from a cardiologist, oncologist, or other specialist at a specific health system, that relationship is especially worth protecting. Losing in-network access to a specialist mid-treatment is not only inconvenient — it can interrupt care at a critical time and result in significant unexpected costs.

05 Review Your Prescription Drug Formulary

Your medications may still be covered — but on different terms

A formulary is the list of prescription drugs your plan covers, organized into tiers that determine how much you pay for each medication. Plans can modify their formularies each year, adding or removing drugs, changing tier assignments, and adjusting cost-sharing amounts.

For each medication you currently take, check whether it remains on the 2027 formulary and whether its tier has changed. Moving from Tier 2 to Tier 3 can increase your monthly copay by $30 to $60 or more for a single drug. Also look for new requirements such as Prior Authorization, Step Therapy, or Quantity Limits, which can add steps and delays to getting the prescriptions you need.

Your preferred pharmacy network matters too

Check whether your regular pharmacy remains a Preferred Pharmacy in your plan’s 2027 network. Using a Preferred Pharmacy typically means lower copays than using a standard in-network pharmacy. If you use a mail-order pharmacy for maintenance medications, verify that the mail-order benefit and associated cost savings are unchanged. The Medicare Plan Finder tool at Medicare.gov allows you to enter your specific medications and compare actual drug costs across available plans in New Jersey.

06 Check for Changes to Your Extra Benefits

Dental, vision, hearing, and OTC benefits vary widely and change annually

One of the most frequently cited reasons people choose Medicare Advantage over Original Medicare is access to extra benefits not covered by traditional Medicare. These typically include dental care, vision exams and eyewear, hearing exams and hearing aids, over-the-counter product allowances, fitness memberships, and in some cases transportation assistance or meal delivery.

These benefits are not standardized and can change significantly from one planned year to the next. Review your ANOC to see whether the annual dental allowance, vision benefit, or OTC card amount has changed for 2027. A reduction in the dental benefit limit from $2,000 to $1,500, for example, could meaningfully affect what you can afford in a given year if you have ongoing dental work.

Some plans operating in New Jersey offer region-specific benefits, including food and produce OTC cards, transportation support for non-emergency medical visits, and telehealth services. If you have been using any of these, confirm they are still available in the 2027 plan year under the same terms.

07 Compare Your Current Plan Against Other Available Options

The goal is not to find something new — it is to confirm what is best for you

The seventh item on this list is not about switching plans for its own sake. It is about making an informed decision — which sometimes means staying exactly where you are and sometimes means recognizing that another plan would serve you better in 2027.

When comparing plans, use your actual situation as the benchmark: the doctors and hospitals you use, the medications you take, and a realistic estimate of how often you expect to need medical care in the coming year. A plan with a lower premium is not necessarily a better plan if its network excludes your cardiologist or its formulary places your daily medications on a higher tier.

Take advantage of free, unbiased counseling available in New Jersey

New Jersey residents can access free, independent Medicare counseling through the State Health Insurance Assistance Program, known as SHIP NJ. SHIP counselors are not affiliated with any insurance company and do not sell plans, which means the guidance they provide is entirely objective. You can reach SHIP NJ at 1-800-792-8820 or visit a local Senior Center to schedule an in-person appointment. The Medicare Plan Finder at Medicare.gov is also an excellent self-service tool for comparing 2027 plans side by side using your specific providers and medications.

The Most Important Thing You Can Do This AEP Is Read Your ANOC

The 2027 Annual Enrollment Period is not simply a window for switching plans. It is an annual opportunity to verify that your current coverage still fits your life — your doctors, your medications, your budget, and your health needs for the year ahead.

When your ANOC arrives in the mail this September, do not set it aside. Work through the seven items in this guide: your premium, your deductible and cost-sharing, your maximum out-of-pocket limit, your provider network, your formulary, your extra benefits, and a comparison of what else is available in your area. Thirty minutes of review can spare you from the kind of disruption Margaret faced in Bergen County — and from months of avoidable costs and inconvenience.

AEP is not a deadline to dread. Approached with the right information, it is one of the most powerful tools available to Medicare enrollees. Use it well.
