Medicare AEP: What To Know and Deadlines

Wade Lashley | Nov 12 2026 14:00

Medicare’s Annual Enrollment Period is an important opportunity to review whether your health coverage still fits your needs. Because plan costs, provider networks, prescription coverage, and added benefits may change each year, a quick review can help you avoid unwelcome surprises and make well-informed choices for the year ahead.

The Medicare Annual Enrollment Period, often called AEP, runs from October 15 through December 7. Any approved changes generally begin on January 1. You do not have to change plans during this time, but reviewing your senior health insurance annually can help confirm that your coverage continues to support both your care and your budget.

Your Medicare Choices During AEP

AEP gives Medicare beneficiaries a designated time to reconsider their coverage as their health needs, prescriptions, and financial priorities change. Medicare decisions do not need to remain the same from year to year, especially when a different option may offer a better overall fit.

If you have Original Medicare, you may find that a Medicare Advantage plan better matches your situation. Medicare Advantage plans combine hospital and medical coverage and may also include prescription drug coverage within a single plan. They can be worth considering for people who want coverage arranged through one plan.

Conversely, someone enrolled in a Medicare Advantage plan may decide that returning to Original Medicare better serves their priorities. Access to providers, the desire to explore Medicare Supplements, or other coverage preferences can all influence that decision.

During AEP, you may also move from one Medicare Advantage plan to another. You can enroll in, change, or leave a standalone Part D prescription drug plan as well. The purpose of this period is not to encourage a change every year; it is to give you the ability to adjust coverage when your circumstances call for it.

Why an Annual Medicare Review Is Worthwhile

Even when you have been happy with your current plan, reviewing it during AEP is a sensible step. Medicare Advantage and Part D plans are offered by private insurance companies, and plan details can look different from one year to the next.

For example, a plan may update its monthly premium, deductible, copayments, coinsurance, network of doctors and hospitals, prescription coverage, or supplemental benefits. A plan that was convenient and affordable this year may not provide the same value in the coming year. Comparing your choices helps you make sure your coverage still aligns with your medical needs and financial goals.

Prescription Drug Plans deserve close attention during the enrollment period. A plan’s formulary, or covered-drug list, can be revised each year. A medication could be placed in a different cost tier or become subject to additional coverage requirements, potentially changing what you pay out of pocket.

It is also wise to verify your providers and pharmacies. Doctors, hospitals, and pharmacies may enter or leave a plan’s network between plan years. Checking these details before you make a decision can help prevent interruptions after your new coverage takes effect.

Consider More Than the Monthly Premium

When comparing Arizona Medicare options, the monthly premium is often the first figure people notice. It matters, but it is only one part of the cost of your health coverage.

A plan with a lower premium does not automatically result in lower healthcare spending over the course of the year. Review the deductible, copayments, coinsurance, annual out-of-pocket maximum, and the costs you expect for medical services and prescriptions. Looking at these factors together offers a clearer picture of what a plan may truly cost.

Additional benefits should be included in your comparison, too. Many Medicare Advantage plans provide benefits that Original Medicare does not typically cover. Depending on the plan, those benefits can include routine dental services, vision care, hearing coverage, fitness programs, transportation support, or allowances for over-the-counter health products.

Since these benefits can change annually, AEP can be a useful time to see whether another plan delivers stronger value for your health and wellness needs. The right comparison considers both the coverage you expect to use and the benefits that matter most to you.

Medicare Guidance Can Make Comparisons Easier

Reviewing Medicare plans can feel complicated because each option may combine costs, provider access, drug coverage, and additional benefits differently. Sorting through those details on your own can make it difficult to determine which plan best serves your particular needs.

Working with a knowledgeable Medicare broker can make the process easier to understand. A Medicare professional can explain plan options, review changes for the upcoming year, and help you compare coverage based on your prescriptions, healthcare needs, preferred providers, and budget.

At Wade Lashley Insurance Broker, I provide personalized Medicare guidance for people seeking greater clarity around Medicare Advantage, Medicare Supplements, Prescription Drug Plans, and Long-Term Care coverage. My goal is to make complex information easier to understand so you can evaluate your options with confidence.

An annual review can also offer reassurance if you decide that keeping your current coverage is the best choice. Medicare help is not only about changing plans. It is about making decisions based on current plan information rather than assuming last year’s coverage will remain unchanged.

Use AEP to Review Your Coverage With Confidence

The Medicare Annual Enrollment Period is more than a deadline for changing plans. It is a valuable time to consider whether your existing coverage continues to support your health, finances, and future care needs.

Review plan notices carefully, compare total expected costs, check your prescription drug coverage, and confirm that your preferred doctors, hospitals, and pharmacies are available through the plan. These steps can help you begin the new year with greater confidence in your Medicare coverage.

Wade Lashley Insurance Broker offers friendly, individualized support for Tucson residents who need help navigating Arizona Medicare choices. Whether you are considering Medicare Advantage, Medicare Supplements, Part D coverage, or Long-Term Care options, I can help you better understand the choices available during AEP and identify coverage that fits your needs and budget.
