Medicare Annual Enrollment: 5 Key FAQs

Posted by Joshua Greenberg on Sep 25 2026 13:00

Medicare’s Annual Enrollment Period (AEP) takes place every year from October 15 through December 7. This limited window gives you an opportunity to review and make changes to your Medicare coverage for the year ahead. Although AEP can feel confusing, understanding the most common questions can help you make informed decisions about your health care and budget.

Even if your current plan seems to be working well, it is worth reading through each of these FAQs carefully. Plan premiums, benefits, provider networks, and prescription drug coverage can change from year to year, so a brief review may help you avoid unwelcome surprises.

What If I Miss the Open Enrollment Deadline?

Unless you qualify for a Special Enrollment Period because of a major life event, you will need to wait until the next year’s enrollment window to make changes. Certain situations, such as moving outside your plan’s service area, losing qualifying coverage, or becoming eligible for certain assistance programs, may create a Special Enrollment Period. However, those opportunities are limited and depend on your circumstances.

This is why it is important to begin reviewing your options well before December 7. Missing the deadline could mean remaining in coverage that no longer fits your providers, medications, health needs, or retirement budget for the following year.

Do I Need to Do Anything If I Am Happy With My Current Plan?

Even if you are satisfied, it may be a good idea to review your coverage. Premiums, provider networks, and drug formularies can change each year. A prescription that was affordable this year could move to a different coverage tier, or a preferred doctor or pharmacy could no longer be in your plan’s network.

Review the Annual Notice of Change from your insurer and compare it with your current needs. For retirees balancing health expenses with retirement income strategies, a quick Medicare plan review can be an important part of protecting savings and maintaining predictable health care costs.

What Changes Can I Make During Open Enrollment?

You can switch from Original Medicare to a Medicare Advantage plan, change from one Advantage plan to another, or modify your Part D prescription coverage. Depending on your current arrangement, you may also be able to move from Medicare Advantage back to Original Medicare, subject to the rules that apply to Medicare supplement insurance in your situation.

These choices matter because Medicare coverage is not one-size-fits-all. Your doctors, medications, preferred hospitals, travel habits, and anticipated health needs can all affect which option is most appropriate. A Medicare Advantage plan comparison may reveal differences in networks, out-of-pocket costs, and added benefits, while a Part D review can help you assess prescription drug coverage for Medicare.

When Can I Learn About Next Year’s Plans?

Information for next year’s plans is available beginning in October. Call 1-800-MEDICARE or visit Medicare.gov. You can use these resources to compare available plans, review benefits, check participating providers, and confirm how your prescriptions are covered.

Starting early gives you more time to review information without rushing. Green Bee Insurance encourages South Florida retirees to gather their current plan materials, medication list, and preferred provider information before evaluating new options. Medicare guidance services can also help you understand how plan changes may affect your broader financial planning for retirement.

What Is the Difference Between Original Medicare and Medicare Advantage?

Original Medicare is government-managed and typically paired with separate drug coverage and optional Medigap. Medicare Advantage plans are offered by private insurers and often bundle medical and drug benefits, with some including extras like dental or vision.

When comparing Medicare supplement versus Advantage coverage, consider how each structure may work with your needs. Original Medicare generally offers broad provider access, while a Medicare Advantage plan may use a provider network and have plan-specific rules for care. The right fit depends on your health care preferences, prescription needs, anticipated costs, and comfort with the plan’s network and coverage requirements.

For people seeking Medicare guidance in Fort Lauderdale, Green Bee Insurance can help make these distinctions easier to understand. The goal is not simply to select a plan, but to help you evaluate senior health insurance options in the context of your full retirement picture.

Why Does AEP Matter for Your Retirement Plan?

Your Medicare decisions can affect more than your monthly premium. Health care expenses may influence retirement budgeting, cash flow, and the resources you have available for the goals that matter most to you. Reviewing coverage annually can help you identify whether your plan remains aligned with your prescriptions, preferred care providers, and expected out-of-pocket costs.

At Green Bee Insurance, we believe Medicare plan counseling should support confident, well-informed decision-making. For individuals and couples in Fort Lauderdale and throughout South Florida, Medicare choices can be considered alongside Social Security claiming strategies, retirement income planning, and long-term protection needs.
