Quick Summary:
When you turn 65 in Wisconsin, start by confirming when your Medicare eligibility begins, deciding whether you need to enroll in Part A and Part B right away, and comparing your choices for prescription drug and supplemental coverage. If you are still working, do not assume you can safely delay Medicare—check how your employer coverage works first so you can avoid gaps and late penalties.
Best Penny Insurance helps people throughout central Wisconsin make this transition with a clear plan. Whether you live in Wisconsin Rapids, Stevens Point, Marshfield, Wausau, or Plover, this checklist can help you prepare for Medicare with more confidence.
Step 1: Mark Your Initial Enrollment Period
Your first Medicare enrollment window is called the Initial Enrollment Period, or IEP. It lasts seven months: the three months before the month you turn 65, your birthday month, and the three months after your birthday month.
For example, if your 65th birthday is in June, your Initial Enrollment Period runs from March 1 through September 30. Starting early is usually the best way to prevent an avoidable coverage gap and give yourself time to compare plans without pressure.
Many people are automatically enrolled in Medicare Part A and Part B if they are already receiving Social Security or Railroad Retirement benefits before they turn 65. If you are not receiving those benefits yet, you will generally need to actively enroll through Social Security. Do not rely on assumptions—confirm your enrollment status and the effective date shown on your Medicare information.

Step 2: Learn the Parts of Medicare Before You Choose Coverage
Medicare has several parts, and understanding the basics makes the rest of the process easier.
- Part A helps cover inpatient hospital care, skilled nursing facility care, hospice, and some home health care.
- Part B helps cover doctor visits, outpatient care, preventive services, lab work, durable medical equipment, and other medical services.
- Part D provides outpatient prescription drug coverage through private plans.
- Medicare Advantage, or Part C, is another way to receive your Part A and Part B benefits through a private insurance plan.
Once you have Part A and Part B, you generally choose one of two main coverage paths. You can stay with Original Medicare and consider a Wisconsin Medicare Supplement policy plus a standalone Part D plan. Or, you can enroll in a Medicare Advantage plan, which commonly includes Part D coverage and may include additional benefits.
The goal is not to pick the option your neighbor chose. It is to choose coverage that works with your doctors, medications, budget, and preferred way of receiving care.
Step 3: Make a List of Your Doctors, Pharmacies, and Medications
Before comparing plans, write down the doctors, clinics, hospitals, specialists, pharmacies, and prescriptions you use. Include the medication name, dosage, and how often you take it. This simple step helps prevent a common Medicare mistake: selecting a plan based only on a low premium without verifying whether it fits your actual care.
This matters especially when considering Medicare Advantage. Medicare Advantage plans can have provider networks, formularies, copays, and prior-authorization rules that vary by plan and county. A plan that looks attractive on a postcard may not be the right fit if your preferred providers are out of network or your medications are not covered favorably.
For Original Medicare with a Wisconsin Medicare Supplement, provider flexibility is often broader because you can generally see Medicare-participating providers nationwide. However, you will still want to compare prescription drug plans and understand the Wisconsin Basic Plan and any optional Medigap riders you are considering.
Step 4: Decide Whether You Need Part A and Part B at 65
For many people who are no longer covered by active employer health insurance, enrolling in both Part A and Part B around age 65 is the straightforward choice. But working past 65 can change the timing.
If you or your spouse has group health coverage from current employment, you may be able to delay Part B without a penalty. The details matter. Ask the employer’s benefits administrator whether the coverage is based on current employment, whether the employer has fewer than 20 employees, and whether Medicare would pay first or second for your care. Smaller-employer coverage may not pay as expected if you delay Medicare.
Coverage that is not based on current employment—such as COBRA, retiree coverage, Marketplace coverage, or most individual coverage—does not automatically protect you from the Part B late-enrollment penalty. Do not wait until COBRA ends to investigate Medicare. That can create a gap in coverage and cause you to miss a limited enrollment opportunity.
If you contribute to a Health Savings Account, pause before enrolling in Part A. Medicare Part A may begin up to six months retroactively when you enroll after age 65, and HSA contributions during months you have Medicare can create tax issues. Talk with your benefits administrator and tax professional before setting your retirement date or enrollment date.
Step 5: Understand Late Enrollment Penalties
Late enrollment penalties are not simply one-time fees. They can increase your monthly costs for a long time, which is why timing deserves attention.
If you do not enroll in Part B when first eligible and do not qualify for a Special Enrollment Period, your Part B premium may increase by 10% for every full 12-month period you could have had Part B but did not enroll. In most cases, that penalty lasts as long as you have Part B.
For Part D, going 63 days or more without creditable prescription drug coverage can lead to a late-enrollment penalty. Creditable coverage means prescription coverage that is expected to pay, on average, at least as much as standard Medicare drug coverage. If you keep employer or retiree drug coverage, ask for the annual creditable-coverage notice and save it.
Part A penalties apply mainly to people who have to pay a premium for Part A and delay enrollment without qualifying for a Special Enrollment Period. Most people qualify for premium-free Part A, but it is still worth confirming your situation.
Step 6: If You Are Still Working, Use the Special Enrollment Period Carefully
If you delay Part B because you or your spouse has qualifying active employer group coverage, you generally have an eight-month Special Enrollment Period
to enroll after the employment ends or the group coverage ends, whichever happens first. You may also enroll while the employment and qualifying coverage are still active.
Do not confuse this eight-month period with COBRA. The clock starts when the job or active group coverage ends, even if you elect COBRA afterward. For many people in Wisconsin Rapids, Stevens Point, Marshfield, Wausau, and Plover, the safest approach is to start planning about a month before employer coverage ends so Medicare can begin without a gap.
You may need documentation from your employer to show that you had qualifying coverage. Keep benefit letters, creditable drug coverage notices, and employment-related paperwork in one place.
Step 7: Compare Your Coverage Path and Enroll on Time
Once Parts A and B are set, compare your coverage choices side by side. Review monthly premiums, estimated drug costs, doctors and hospitals, maximum out-of-pocket exposure, travel needs, and extra benefits. If you prefer Original Medicare, compare Wisconsin Medicare Supplement options and Part D plans. If you prefer Medicare Advantage, compare the specific plans available where you live—not just the plan names.

FAQ
When should I start planning for Medicare if I turn 65 soon?
Begin at least three months before your 65th birthday month. That is when your Initial Enrollment Period opens, and it gives you time to confirm your enrollment, compare plans, and avoid a rushed decision.
Do I have to take Medicare at 65 if I am still working?
Not always. You may be able to delay Part B if you or your spouse has qualifying group health coverage based on current employment. Confirm how the employer plan coordinates with Medicare before delaying any part of Medicare.
Will COBRA let me delay Part B without a penalty?
Generally, no. COBRA is not considered active employer coverage for the Part B Special Enrollment Period. Waiting for COBRA to end can cause a gap and may result in a late-enrollment penalty.
Do I need drug coverage if I do not take prescriptions?
It is still important to consider Part D. If you go 63 days or more without creditable drug coverage, you may face a late-enrollment penalty when you enroll later.
What is the biggest Medicare mistake to avoid?
Assuming all coverage works the same. Verify enrollment timing, employer coverage rules, doctors, medications, networks, and total costs before making a decision.
