Medicare AEP: What To Know and Deadlines

Joseph Cioffi | Nov 12 2026 14:00

Medicare’s Annual Enrollment Period is an important opportunity to make sure your health coverage still matches your needs. Because plan costs, provider networks, prescription drug coverage, and extra benefits can change from one year to the next, an annual review can help you avoid unwelcome surprises.

The Medicare Annual Enrollment Period runs from October 15 through December 7. Changes made during this window generally begin on January 1. You are not required to change plans, but reviewing your coverage gives you the information needed to decide whether keeping it remains the best choice.

What You Can Do During Medicare Annual Enrollment

Medicare Annual Enrollment Period in Oregon gives beneficiaries a defined time to reassess their coverage and make certain changes for the following plan year. Since health needs and financial priorities may look different than they did last year, this period is designed to provide flexibility.

If you have Original Medicare, you may decide that a Medicare Advantage plan offers a better fit. Medicare Advantage plans combine hospital and medical coverage and frequently include prescription drug coverage in a single plan. Depending on the plan, they may also offer additional benefits beyond what Original Medicare covers.

On the other hand, someone enrolled in Medicare Advantage may determine that returning to Original Medicare better supports their priorities, such as broader access to providers or the ability to pair Original Medicare with supplemental coverage. Beneficiaries may also change from one Medicare Advantage plan to another when another available option better suits their needs.

Annual Enrollment is also the time to enroll in, change, or leave a standalone Medicare Part D prescription drug plan. Medicare decisions do not have to remain unchanged year after year. A thoughtful review can help you make adjustments when your circumstances or available plans have changed.

Why an Annual Medicare Review Is Worth Your Time

Even when you are comfortable with your current coverage, reviewing it annually is a practical step. Medicare Advantage and Medicare Part D plans are offered through private insurance companies, and the details of those plans may be updated for the next year.

Monthly premiums, deductibles, copayments, coinsurance, provider networks, drug coverage, and supplemental benefits can all be different from one plan year to the next. A plan that offered good value this year may not provide the same convenience or affordability next year.

For people seeking Medicare help in Oregon, an annual review can bring clarity to these changes before new coverage begins. Comparing the available choices helps ensure that your plan continues to support your medical needs as well as your budget.

Review Prescription Drug Coverage Carefully

Prescription drug coverage is one area that deserves close attention during Annual Enrollment. Each Part D plan and many Medicare Advantage plans use a formulary, which is the list of medications the plan covers. Formularies may change each year.

A medication you take could move to a different cost tier, or the plan could require additional approval before covering it. These changes may affect what you pay out of pocket, even when you remain enrolled in the same plan.

When comparing Medicare drug plans in Oregon, review your current medications and how they are covered under each option. Taking this step can help you better understand the potential cost and access considerations for the year ahead.

Confirm Your Doctors, Hospitals, and Pharmacies

Provider and pharmacy networks are another key part of comparing Medicare plans. Physicians, hospitals, pharmacies, and other healthcare providers can enter or leave a plan’s network between plan years.

Before making a decision, confirm whether the doctors and facilities you prefer are included in the network for the coverage you are considering. This is particularly important when evaluating Medicare Advantage plans, since network rules can vary by plan.

It can also be helpful to understand the difference between HMO and PPO Medicare options. Network access, referral requirements, and out-of-network coverage may differ, so it is important to consider how each plan structure fits the way you receive care.

Consider More Than the Monthly Premium

It is understandable to begin by looking at a plan’s monthly premium. However, the premium is only one piece of the larger Medicare cost picture. A low or even $0 premium Medicare Advantage option may have other costs that should be reviewed carefully.

Compare deductibles, copayments, coinsurance, and the annual maximum out-of-pocket amount, often called the MOOP. Also consider the medical services and prescription medications you expect to use throughout the year. Looking at these details together offers a more realistic view of what a plan may cost overall.

Additional benefits deserve consideration as well. Medicare Advantage plans may include benefits that Original Medicare does not cover, such as routine dental, vision, hearing, fitness, transportation, or over-the-counter health product allowances.

Those benefits can change each year, just like a plan’s costs and network. Reviewing them during Annual Enrollment may help you identify coverage that provides stronger value while supporting your health and wellness goals.

Comparing Medigap and Medicare Advantage Options

For some beneficiaries, the decision involves comparing Medigap coverage with Medicare Advantage. Original Medicare paired with a Medicare Supplement plan can offer a different approach to managing out-of-pocket costs and provider access than a Medicare Advantage plan.

Medigap options, including Medicare Supplement Plan G, Plan N, and high-deductible Plan G, may be part of the conversation for people evaluating their broader coverage strategy. Medicare Advantage plans may instead appeal to those seeking an all-in-one plan that can include prescription drug coverage and supplemental benefits.

The right choice depends on individual circumstances. Your preferred providers, prescription medications, expected healthcare use, budget, and comfort with plan network rules should all be part of the evaluation.

Guidance Can Make Medicare Decisions Easier

Sorting through Medicare options can feel complicated. Plans can differ in their costs, formularies, provider networks, benefits, and rules, making it difficult to see which choice best aligns with your situation.

An annual review does not mean you need to switch plans every year. Sometimes, the review simply confirms that your existing coverage is still a good fit. The value is in making a decision based on current plan information rather than assumptions from the prior year.

Use Annual Enrollment to Plan With Confidence

The Annual Enrollment Period is about more than changing coverage. It is an opportunity to check whether your current Medicare plan continues to serve your health needs, budget, and priorities for the coming year.

Review plan notices, compare total costs, verify prescription drug coverage, and confirm your provider network. These steps can help you move into the new year with greater confidence in your Medicare coverage.
