Medicare AEP: What To Know and Deadlines

Christine Biemuller | Nov 12 2026 16:00

Medicare’s Annual Enrollment Period (AEP) is an important opportunity for beneficiaries to revisit their health coverage. It can be tempting to leave a plan unchanged from one year to the next, but Medicare plans are updated annually. Changes to costs, prescription coverage, provider networks, and extra benefits may affect how well your plan serves you in the year ahead.

The Medicare Annual Enrollment Period takes place from October 15 through December 7. Coverage selections or changes made during this period generally begin on January 1. You do not have to make a change, but an annual review can help you confirm that your coverage still matches your healthcare needs and budget before the new plan year starts.

Medicare Decisions You Can Make During AEP

AEP gives Medicare beneficiaries time to consider whether their current coverage remains appropriate for their circumstances. Healthcare needs, prescriptions, preferred providers, and financial priorities can all change. This enrollment window provides a structured time to adjust coverage when needed.

If you have Original Medicare, you may decide that a Medicare Advantage plan is a better fit. Medicare Advantage plans combine hospital and medical coverage and may also include prescription drug coverage in one plan. For some people, this approach may offer a convenient way to manage their Medicare benefits.

Others may be enrolled in a Medicare Advantage plan and decide that returning to Original Medicare better supports their priorities. Broader provider access or the ability to add supplemental coverage may be important considerations. Your Senior Savior helps individuals and families in Langhorne, Pennsylvania understand how these options compare based on their individual circumstances.

During the Annual Enrollment Period, beneficiaries may also:

  • Move from one Medicare Advantage plan to another.
  • Change from Original Medicare to a Medicare Advantage plan.
  • Leave a Medicare Advantage plan and return to Original Medicare.
  • Enroll in, switch, or discontinue a standalone Medicare Part D prescription drug plan.

Medicare coverage does not have to be treated as a permanent decision. AEP creates an opportunity to review current information and make changes when a different option better supports your health or financial goals.

Why an Annual Medicare Review Matters

Even when you are happy with your present Medicare plan, reviewing it each year is still a wise step. Private insurance companies offer Medicare Advantage and Part D plans, and they can make changes to those plans for the upcoming year. What worked well in the past may not deliver the same value going forward.

Plan updates can involve monthly premiums, deductibles, copayments, coinsurance, provider networks, prescription coverage, and supplemental benefits. A change in any of these areas could affect your out-of-pocket costs or how easily you can access the care you need. Comparing your options helps you make decisions using current plan details rather than last year’s information.

Your prescription drug coverage deserves close attention during AEP. Each plan has a formulary, which is its list of covered medications, and that list can change from year to year. A medication may be placed in a different cost tier or require additional approval before it is covered, potentially increasing what you pay.

It is also important to verify provider networks. Physicians, hospitals, and pharmacies may enter or leave a plan’s network between plan years. Confirming that your preferred healthcare professionals and pharmacies remain available through your plan can reduce the risk of an unwelcome surprise after new coverage begins.

Compare More Than the Monthly Premium

The monthly premium is often the first number people notice when comparing Medicare plans. While it is an important factor, it is only one part of the overall cost of coverage. A plan with a lower premium may not necessarily have the lowest total cost for your situation.

Consider deductibles, copayments, coinsurance, annual out-of-pocket maximums, and the medical and prescription expenses you anticipate during the year. Looking at these costs together offers a more complete picture of what you may actually spend. This broader comparison can help you identify coverage that fits both your care needs and your budget.

Extra benefits should also be part of your Medicare review. Many Medicare Advantage plans offer services that are not included with Original Medicare. Depending on the plan, those benefits can include routine dental care, vision services, hearing support, fitness programs, transportation assistance, or an allowance for over-the-counter health products.

Because supplemental benefits may be revised each year, AEP may reveal plans with features that better support your health and wellness. The value of these benefits depends on whether you expect to use them, so it is helpful to review the details instead of assuming they will remain the same.

How Medicare Guidance Can Help

Medicare plan comparisons can feel complicated. Plans may differ in their premiums, cost-sharing requirements, drug coverage, provider networks, and added benefits. Sorting through those differences can be difficult when you are trying to determine which option best fits your own priorities.

Working with a knowledgeable Medicare advisor can make the process easier to navigate. At Your Senior Savior, we help clients review available options, understand annual plan changes, and compare coverage based on their healthcare needs and financial goals. Our team provides personalized Medicare guidance for seniors and families in the Langhorne, Pennsylvania area and beyond.

Professional support can also bring peace of mind. Keeping your existing coverage may still be the right decision after a review. The purpose of an annual Medicare review is not to change plans simply for the sake of making a change; it is to make a confident choice based on accurate, up-to-date information.

Use AEP to Prepare for the New Plan Year

The Medicare Annual Enrollment Period is more than a time to select a different plan. It is a valuable chance to evaluate whether your current coverage continues to support your health, finances, and future needs. Setting aside time for this review can help you approach the coming year with greater clarity.

Review plan notices, compare your expected overall costs, check that your prescriptions are covered, and confirm that your preferred providers and pharmacies are available. These steps can help you determine whether staying with your current plan makes sense or whether another Medicare option may better meet your needs.
