Medicare AEP: What To Know and Deadlines
Cynthia Cherry | Nov 12 2026 16:00
The Medicare Annual Enrollment Period is an important opportunity to make sure your health coverage still fits your life. Plans can change from year to year, including their costs, provider networks, prescription coverage, and extra benefits. A yearly review helps you understand those updates before they affect your care or budget.
Medicare’s Annual Enrollment Period runs from October 15 through December 7. Changes made during this timeframe generally begin on January 1. You do not have to change plans, but reviewing your coverage can help you move into the new plan year with fewer surprises.
What You Can Do During Medicare Annual Enrollment
Healthcare needs are not always the same from one year to the next. A new medication, a preferred doctor, a change in finances, or a different level of medical care can all affect which Medicare coverage choices make the most sense. The Annual Enrollment Period gives beneficiaries a set time to consider whether an adjustment is appropriate.
If you have Original Medicare, you may decide that a Medicare Advantage plan is a better match for your current needs. Medicare Advantage plans combine hospital and medical coverage, and many include prescription drug coverage within the same plan.
On the other hand, a person with a Medicare Advantage plan may decide that returning to Original Medicare better supports their priorities. Broader access to providers or the ability to use supplemental coverage may be especially important considerations when reviewing Medicare plans in Illinois.
During this enrollment period, you may also be able to:
- Move from one Medicare Advantage plan to another.
- Leave a Medicare Advantage plan and return to Original Medicare.
- Enroll in, change, or discontinue a stand-alone Medicare Part D prescription drug plan.
- Review whether your current coverage continues to align with your health needs and expected expenses.
Medicare decisions do not need to remain unchanged simply because a plan worked well in the past. Annual Enrollment gives you the chance to revisit those decisions using current information.
Why Medicare Coverage Should Be Reviewed Each Year
It can be tempting to keep the same Medicare plan when you have been generally satisfied with it. Still, Medicare Advantage and Part D plans are offered by private insurance companies, and plan details may be revised annually. What was a strong fit this year may operate differently next year.
Changes may involve monthly premiums, deductibles, copayments, coinsurance, prescription drug formularies, participating doctors, pharmacies, and added plan benefits. Even a small change in one of these areas can have a meaningful effect on your out-of-pocket costs or convenience.
A Medicare annual plan review allows you to compare your existing plan with the available options for the coming year. At Cherry Insurance, we help clients throughout Chicago and Illinois look beyond assumptions and focus on the coverage details that matter most to them.
Check Prescription Drug Coverage Carefully
Prescription drug coverage is one of the most important parts of an Annual Enrollment review. A plan’s formulary is its list of covered medications, and that list can be updated each plan year. Your medication may remain covered, move to a different cost tier, or become subject to additional coverage requirements.
For example, a medication could require prior authorization or step therapy before the plan will cover it. A drug may also move to a tier with a higher copayment or coinsurance amount. These changes can increase what you pay at the pharmacy, even if the plan’s monthly premium stays similar.
When you compare Medicare plans, review each current prescription, its dosage, and the pharmacy you prefer to use. This can provide a clearer view of how a plan may work in real life rather than relying only on broad plan summaries.
Confirm Your Doctors, Hospitals, and Pharmacies
Provider networks also deserve close attention, especially for people considering Medicare Advantage plans in Illinois. Doctors, specialists, hospitals, and pharmacies may enter or leave a plan network from one year to the next. A provider who participates today may not be in-network after January 1.
Checking your preferred providers before selecting or keeping a plan can help prevent an unexpected disruption in care. It may also help you avoid higher out-of-network costs, depending on the plan type and its rules.
This step is particularly valuable if you see specialists regularly, receive care through a specific hospital system, or rely on a particular pharmacy. A Medicare broker in Chicago can help you review network details, but it is also wise to confirm participation directly with the provider and plan.
Consider Total Costs, Not Only the Premium
A low monthly premium can be appealing, but it is not the full measure of a Medicare plan’s value. The most affordable-looking option may have higher costs when you need services, fill prescriptions, or reach certain coverage limits.
For a more complete comparison, consider the expenses you may face over the entire year. Important costs to examine include:
- The monthly plan premium.
- Medical and prescription deductibles.
- Copayments for doctor visits, specialists, urgent care, and hospital services.
- Coinsurance amounts for covered care.
- The annual out-of-pocket maximum for covered medical services.
- Your expected costs for prescriptions and routine healthcare needs.
Looking at these figures together can help you compare Medicare coverage choices more realistically. The goal is not simply to find the lowest premium. It is to choose coverage that supports your expected care while remaining comfortable for your budget.
Review Dental, Vision, and Other Added Benefits
Many Medicare Advantage plans include benefits that Original Medicare generally does not cover. Depending on the plan, these may include routine dental services, vision care, hearing support, fitness programs, transportation assistance, or allowances for eligible over-the-counter health products.
These benefits can be valuable, but they vary by plan and can change each year. Dental and vision insurance for seniors in Illinois may also be worth considering when your Medicare coverage does not provide the level of support you want for routine care.
As part of a plan review, look at how each benefit works. Check the available allowance, network requirements, service limits, and any costs you may owe. A benefit is most useful when it fits the services you are likely to use.
Get Clear Medicare Guidance Before Making a Decision
Comparing Medicare options can feel complicated because every plan combines costs, coverage rules, drug benefits, networks, and supplemental features differently. It is not always easy to see how those details will affect your personal situation.
Cherry Insurance provides clear, pressure-free Medicare guidance for beneficiaries in Chicago, throughout Illinois, and remotely in other licensed states. As an independent Medicare advisor, Cynthia Cherry can help explain annual plan changes and compare options based on your doctors, medications, healthcare preferences, and financial goals.
Professional support does not mean you must switch plans. In many cases, the review simply confirms that your existing coverage remains appropriate. The value comes from making a decision with up-to-date details rather than assuming last year’s plan will work exactly the same way next year.
Use AEP to Prepare for the Year Ahead
The Annual Enrollment Period is about more than changing insurance plans. It is a practical time to confirm that your Medicare coverage still supports your health, your preferred providers, and your budget for the coming year.
Review plan notices, compare total costs, check your prescription drugs, and verify your doctors, hospitals, and pharmacies. Taking these steps before the December 7 deadline can help you avoid coverage surprises when the new year begins.
