Medicare Enrollment Checklist: Breaking It All Down

Preparing for Medicare enrollment can feel overwhelming at first, with so many decisions to make and deadlines to meet. A checklist can simplify the process, whether you’re preparing for your 65th birthday or reassessing your options during enrollment periods. Breaking the process into manageable steps can help you navigate Medicare enrollment with confidence.

Using a Medicare enrollment checklist helps you stay on top of important details, like choosing the right insurance coverage or avoiding missed deadlines. Whether you’re starting with initial enrollment or reviewing your options down the road, having a plan makes it easier to compare Medicare plans and find coverage that suits your needs and budget.

This guide offers practical advice for every stage, from getting ready before turning 65 to reviewing your plan annually. It’s designed to help you make smart choices, avoid penalties, and get the most out of your Medicare coverage. Whether you’re new to the process or looking for a fresh perspective, this checklist will help you feel more prepared.

Medicare Pre-Enrollment Checklist

Starting your Medicare enrollment preparations months before your 65th birthday can help you feel ready when the time comes. Early planning gives you the chance to gather information, weigh your options, and organize the steps you’ll need to take. By breaking the process into clear tasks, you can reduce stress and make decisions with confidence. 

Key Steps to Take as You Approach Eligibility:

Step 1) Understand the Parts of Medicare: Begin by learning how Medicare works. Original Medicare Part A covers inpatient care such as hospital stays, while Part B focuses on outpatient services, including routine doctor visits and preventive care. You can also look into options like Medicare supplement plans to help with costs not covered by Original Medicare, or a Medicare Advantage plan, which may include additional perks like dental or vision coverage. Knowing the structure helps clarify your options.

Step 2) Assess Your Healthcare Needs: Consider your current medical needs and any changes you expect in the near future. Think about the doctors you see regularly, the prescriptions you rely on, and any upcoming treatments. Research prescription drug plans (Part D) early to make sure you understand the coverage available for your medications.

Step 3) Review Costs and Plan Availability in Your Area: Medicare costs can go beyond monthly premiums. Be sure to look at deductibles, co-pays, and out-of-pocket expenses when comparing plans. Using tools and resources like the State Health Insurance Assistance Program can help you explore what’s available and make more informed choices.

Step 4) Gather Resources for Support: Keep a list of contacts and organizations that can provide guidance, whether that’s your state insurance office or a financial advisor. Having help available when questions arise can make the process much easier.

Medicare Enrollment Checklist

When it’s time to officially enroll in Medicare, understanding both the steps to take and the right timing is just as important as the coverage itself. Your initial enrollment window is your opportunity to establish healthcare coverage that supports you in the years ahead. By following a clear and organized plan, you can minimize the risk of coverage gaps, unexpected costs, or confusion about your benefits.

Steps to Complete Your Medicare Enrollment:

Step 1) Be Aware of the Initial Enrollment Period: The initial enrollment period lasts for seven months—beginning three months before your 65th birthday month and ending three months after. This is your window to enroll in Medicare Parts A and B. If you’re already receiving Social Security benefits, you might be automatically enrolled, but it’s still wise to confirm your coverage.

Step 2) Organize the Necessary Documents: Having the right paperwork ready can help avoid unnecessary delays. Documents like your birth certificate, Social Security number, and any records of employer-based insurance are usually required. It’s better to gather these early than scramble to find them later.

Step 3) Choose a Plan That Works for You: Decide whether to stick with Original Medicare Part A and Part B or switch to a Medicare Advantage plan that includes additional services, like vision or hearing care. Some people also choose a Medicare supplement plan to help cover out-of-pocket expenses, such as co-pays and deductibles. Weigh your needs to find the best fit.

Step 4) Explore Prescription Drug Coverage: If you take prescription medications, research Part D prescription drug plans that cover your specific needs. Each plan has its own costs and formulary, so comparing options ahead of time can save money and frustration.

Step 5) Review Your Enrollment Confirmation: Once you’ve completed enrollment, double-check that all details match what you selected. Confirming everything now can help you avoid any surprises once your Medicare coverage begins.

Medicare Annual Enrollment Checklist

Each year, Medicare participants have the opportunity to reassess their healthcare coverage. The Medicare Annual Enrollment Period (AEP) is the perfect time to make updates, whether it’s adjusting your prescription drug coverage, selecting a new plan, or confirming that your current choice still meets your needs. By reviewing your plan carefully, you can ensure it fits both your health and financial goals. Let’s explore the timelines and steps that can help you make the most of this enrollment period.

Key Enrollment Periods to Remember

Medicare offers multiple windows throughout the year to make changes. Knowing these dates will help you stay organized and take action when needed:

Annual Enrollment Period (October 15–December 7): During this timeframe, you can change your Medicare Advantage plans, modify your Part D coverage, or move from Original Medicare Part A and Part B to a Medicare Advantage plan. If you’re in an Advantage plan and want to switch back to Original Medicare, this is also your chance.

Medicare Advantage Open Enrollment (January 1–March 31): If you currently have a Medicare Advantage plan, this period lets you switch to another Advantage plan, return to Original Medicare, or sign up for a Part D prescription drug plan if your current plan doesn’t include drug coverage.

Five-Star Special Enrollment (December 8–November 30 of the following year): Plans with a five-star rating allow you to switch to them once per year outside the standard enrollment periods. Check to see if a highly rated Medicare Advantage plan or Part D plan is available in your area.

Steps to Take During Annual Enrollment:

Step 1) Assess Your Current Plan’s Performance: Think about whether your current plan worked for you over the past year. Did it meet your healthcare needs? Were your preferred doctors or specialists covered? If you faced issues with costs, networks, or benefits, now is the time to explore other options.

Step 2) Review Costs and Changes: Medicare plans often adjust their pricing, including premiums, deductibles, and co-pays, each year. If you’ve noticed higher costs, compare other plans to see if they offer better coverage at a lower price. It’s worth evaluating your total out-of-pocket expenses rather than focusing solely on premiums.

Step 3) Check Prescription Drug Coverage: If you’re enrolled in Part D, look at your prescription drug coverage to confirm your medications are still covered. Plans change their formularies every year, so a drug you rely on may no longer be included or might now cost more.

Step 4) Explore Cost-Saving Strategies: If your income affects your premiums due to Medicare’s Income-Related Monthly Adjustment Amount (IRMAA), consider ways to reduce taxable income. Adjusting withdrawals from retirement accounts or using other financial strategies might help lower your overall costs.

Step 5) Look at New Benefits: Some Medicare Advantage plans add extra features each year, like dental, vision, or wellness programs. Even if your current plan seems sufficient, it’s worth exploring whether a new plan offers additional value at a similar cost.

Step 6) Double-Check Your Choice: After making a selection, review the plan details carefully to confirm it meets your needs. Verify that your doctors are in-network, your prescriptions are covered, and the cost structure matches your expectations. Small mistakes can lead to big surprises later.

Medicare Enrollment FAQs

Medicare is a complex system, and it’s normal to have questions about what is and isn’t covered, as well as how to navigate potential penalties. Taking time to understand the details can make it easier to choose coverage that aligns with your healthcare and financial needs. Below, we’ve answered some of the most frequently asked questions about Medicare enrollment to help you make informed decisions.

What Services and Expenses Does Medicare Not Cover?

Medicare provides extensive benefits but excludes several key services and expenses that are often important to older adults. These gaps can lead to significant out-of-pocket costs unless you have supplemental insurance or savings. Below are some common services and expenses not covered by Medicare:

Long-Term Care: Medicare does not include coverage for extended stays in nursing homes or ongoing in-home caregiving services. These expenses are typically paid out of pocket or through long-term care insurance.

Dental Services: Routine dental care, including cleanings, fillings, extractions, and dentures, is excluded. Medicare may cover dental care if it’s related to a covered medical procedure, such as cancer treatment or heart surgery, but these cases are rare.

Vision and Eyeglasses: Routine vision exams for corrective lenses and the cost of prescription glasses are not part of Medicare benefits. You’ll need separate vision insurance or personal savings for these expenses.

Hearing Aids: Devices for hearing loss and the exams required for fitting them are not covered. These costs often require private insurance or out-of-pocket payment.

Routine Health Checkups: Medicare provides limited preventive services but does not cover general health exams like annual physicals. Many individuals seek additional insurance to fill this gap.

International Medical Care: Medical services provided outside of the U.S. are generally not included in Medicare’s coverage. Travelers are encouraged to purchase supplemental insurance to cover potential medical emergencies while abroad.

Prescription Medications Without Part D: Medicare does not cover outpatient prescription drugs unless you enroll in a Part D plan. Without this additional plan, medication costs must be fully paid by the individual.

No Cap on Out-of-Pocket Costs: Original Medicare (that’s Parts A and B) has no annual limit on out-of-pocket expenses, which can result in significant costs for those with chronic or severe conditions. For this reason, Many supplement their coverage with Medicare Supplement (Medigap) plans for coinsurance and deductibles or choose Medicare Advantage plans, which include annual out-of-pocket maximums to manage expenses.

Please Note: Medicare does not cover some services you might not expect, including cosmetic procedures, massage therapy, concierge care, or regular physical exams. If you visit a provider who has opted out of Medicare, you’ll likely need to pay the full amount unless it’s an emergency. Routine dental treatments, vision checkups, and hearing aids are also excluded, though certain exceptions may apply if the care is linked to major medical procedures like cancer treatments or heart valve repairs.¹

Why Do People Leave Medicare Advantage Plans?

While Medicare Advantage plans offer additional benefits, they aren’t always the best option for every individual. Some enrollees find that these plans don’t meet their expectations. Here’s why some people choose to return to Original Medicare:

Restricted Provider Networks: Advantage plans often require you to stay within a limited network of doctors and hospitals. If your preferred providers aren’t included, accessing care can become more expensive or inconvenient.

Higher Costs Than Expected: Although these plans frequently have lower premiums, enrollees can still face high out-of-pocket expenses through co-pays, deductibles, or costs for uncovered services.

Uncertainty About Coverage: Some people find that the details of their plan are unclear, leading to surprises about what services are actually included or excluded.

What Happens If You Skip Open Enrollment?

The Annual Enrollment Period is your opportunity to assess your current Medicare plan and make adjustments. If you don’t take action during this time, your plan will automatically renew. While just allowing yourself to automatically renew might seem convenient and hassle-free, it could lead to overlooked changes or missed opportunities for better coverage. Here are some things to consider:

Plan Changes Could Impact You: Medicare plans often update their provider networks, premiums, and benefits annually. These changes could lead to higher costs or fewer services, even if you stick with the same plan.

Your Health May Have Changed: If your prescriptions or medical needs are different from last year, your current plan might no longer meet your needs. Without reviewing your options, you may miss out on better coverage.

Limited Opportunities to Adjust Later: Once the enrollment period closes, your ability to make changes becomes restricted. If your plan no longer aligns with your needs, you could be locked into it for the following year.

What Is the Part D Late Enrollment Penalty?

The Part D late enrollment penalty is applied if you delay signing up for prescription drug coverage when you first qualify. This fee is intended to encourage timely enrollment in prescription drug plans and can significantly increase your monthly premium if you miss the initial opportunity to enroll. Knowing how the penalty is calculated and how to avoid it can help you sidestep unnecessary costs.

Medicare calculates the penalty based on the amount of time you go without qualifying drug coverage. For each month you’re without Part D prescription drug coverage or comparable creditable coverage, Medicare adds 1% of the national base premium to your monthly premium. The penalty grows with every month of delayed enrollment and is cumulative, which means it can lead to a noticeable increase in your costs. Once the penalty is applied, it becomes a permanent part of your monthly premium for as long as you’re enrolled in Part D.

To avoid this penalty, it’s important to enroll in a Part D plan during your initial enrollment window or confirm that your existing drug coverage through an employer or union is considered creditable. If you’re unsure whether your coverage qualifies, it’s a good idea to ask for written confirmation from your plan provider. Acting early can save you from long-term financial consequences.

Please Note: If you believe a Part D late enrollment penalty is incorrect, you can appeal by submitting a form and proof of prior creditable coverage within 60 days. You must pay the penalty during the process to avoid disenrollment. Medicare reviews appeals within 90 days, adjusting premiums and issuing refunds if the penalty is overturned.²

Does Switching from Medicare Advantage to Original Medicare Involve Medical Underwriting?

Original Medicare (Parts A and B) allows enrollment without requiring medical underwriting, meaning pre-existing conditions or health assessments won’t prevent you from signing up.³ However, if you initially choose a Medicare Advantage plan and later decide to switch back to Original Medicare, applying for a Medigap policy might involve underwriting.

Medigap plans help cover expenses that Original Medicare doesn’t pay, such as deductibles, coinsurance, and copayments. Switching from Medicare Advantage to Original Medicare often means insurers can assess your health during underwriting, potentially leading to higher premiums or denial of coverage if you have pre-existing conditions.

There are exceptions known as “guaranteed issue rights,” which let you buy a Medigap policy without underwriting in specific cases. One such exception occurs during your initial Medigap Open Enrollment Period—a six-month window starting when you turn 65 and are enrolled in Part B.⁴ Another example applies if you enrolled in a Medicare Advantage plan when first eligible at age 65 but decide to return to Original Medicare within the first year. These situations allow you to secure a Medigap policy without an underwriting review.⁵

Please Note: It’s important to note that Original Medicare itself does not require medical underwriting at any time. The underwriting considerations apply specifically to Medigap policies when switching from Medicare Advantage to Original Medicare.
