Medicare AEP Deadlines and Annual Coverage Reviews

Brooke Riffell| Oct 20 2026 14:00

The Medicare Annual Enrollment Period, often called AEP, is an important opportunity to revisit your health coverage. It can be tempting to let your current plan continue automatically, especially if it has worked well in the past. However, Medicare plans can change each year, including their costs, provider networks, prescription coverage, and extra benefits.

The Annual Enrollment Period takes place from October 15 through December 7. Changes made during this period generally begin on January 1. You do not have to change plans, but an annual Medicare review can help you determine whether your coverage continues to fit your medical needs and budget for the year ahead.

Medicare Changes You Can Make During AEP

AEP gives Medicare beneficiaries time to make coverage choices based on their current circumstances. Health needs, medications, preferred doctors, and financial priorities can all change. This enrollment window provides a chance to make adjustments when your existing coverage no longer feels like the best match.

Someone with Original Medicare may decide that a Medicare Advantage plan is a better fit. Medicare Advantage plans combine hospital and medical coverage and often include prescription drug coverage in one plan. In some cases, a person enrolled in Medicare Advantage may instead prefer to return to Original Medicare, particularly if broader provider access or supplemental coverage is more important to them.

During AEP, beneficiaries may also move from one Medicare Advantage plan to another. A different plan may offer a provider network, cost structure, or benefit package that better supports their needs. You may also enroll in, change, or leave a standalone Medicare Part D prescription drug plan during this period.

Medicare decisions are not necessarily permanent. The Annual Enrollment Period is designed to give beneficiaries an opportunity to compare their choices and make informed updates when circumstances or plan details change.

Why an Annual Medicare Review Is Worth Your Time

Even when you are happy with your Medicare coverage, reviewing it annually is a wise step. Medicare Advantage and Part D plans are offered by private insurance carriers, and those carriers may revise plan details from one year to the next.

Plan premiums, deductibles, copayments, coinsurance, provider networks, prescription drug coverage, and supplemental benefits may all be different for the upcoming plan year. A plan that delivered good value this year may not offer the same convenience or affordability next year. Comparing Medicare plans in Springfield, Missouri, can help you make sure your coverage still aligns with both your healthcare needs and financial goals.

Prescription drug coverage should receive close attention during the Medicare Annual Enrollment Period. A plan’s formulary, or covered drug list, can change annually. A medication may be assigned to a different cost tier or become subject to additional coverage requirements, which can affect what you pay out of pocket.

It is also important to review provider networks. Doctors, hospitals, pharmacies, and other healthcare providers may enter or leave a plan network between one plan year and the next. Checking that your preferred providers remain in-network can help reduce the risk of an unexpected interruption after new coverage starts.

Compare More Than the Monthly Premium

Monthly premiums are often the first number people notice when evaluating Medicare plans. While the premium is important, it is only one part of the total cost of coverage.

A lower premium does not always result in lower healthcare spending over the course of a year. Consider the plan deductible, copayments, coinsurance, annual out-of-pocket maximum, and the medical and prescription expenses you expect to have. Looking at these costs together offers a more complete view of what a plan may mean for your budget.

Additional benefits also deserve a place in your review. Many Medicare Advantage plans include benefits that Original Medicare does not provide. Depending on the individual plan, those benefits may include routine dental care, vision services, hearing support, fitness memberships, transportation assistance, or allowances for eligible over-the-counter health items.

Because these added benefits may change from year to year, AEP is a helpful time to see whether another plan offers stronger value for your overall health and wellness needs.
