Turning 65 in Wisconsin: your Medicare checklist
Key takeaways
- Your Initial Enrollment Period (IEP) is a 7-month window — 3 months before, your birthday month, and 3 months after you turn 65
- Missing Part B without creditable coverage creates a permanent lifelong penalty of 10% per 12-month gap
- At 65 you choose between two tracks: Medicare Advantage or Original Medicare + Wisconsin Medigap + Part D
- Wisconsin does not use Plan G or Plan N — Wisconsin uses a Basic Plan + optional riders system

- Start the process 3 months before your 65th birthday month
Your Initial Enrollment Period: the 7-month window
Every person turning 65 gets an Initial Enrollment Period (IEP) — a 7-month window to enroll in Medicare. Missing this window without creditable coverage is one of the most expensive mistakes a Wisconsin resident can make.
If you enroll in Part B during these 3 months, coverage starts on the first day of your birthday month. This is the ideal window — it gives time to compare plans and have everything ready before you're eligible.
Start here: schedule your consultation with us nowMedicare Part A and Part B become effective the first day of this month. If you enroll during your birthday month, coverage starts the first day of the following month.
Enrolling in month 5, 6, or 7 of your IEP means coverage starts 2–3 months after you sign up. This gap creates risk. Don't wait.
The two decisions at 65
Enrolling in Medicare Part A and Part B through Social Security is the mechanical step. The strategic decisions — the ones with long-term cost implications — are:
Do you delay Part B?
If you're actively covered by employer health insurance through an employer with 20 or more employees, you can delay Part B penalty-free while that coverage is active. When employer coverage ends, you get a Special Enrollment Period to add Part B without penalty.
If your employer has fewer than 20 employees, Medicare is primary — don't delay Part B.
⚠️ Retiree coverage, COBRA, and marketplace plans do not count as creditable coverage to delay Part B. Confirm your situation with us before deciding.
Which track: Advantage or Medigap?
Once enrolled in Part A and B, you choose your coverage approach:
- Track A: Medicare Advantage (Part C) — replaces Original Medicare with a private plan. Lower premiums, networks, copays, usually includes drugs.
- Track B: Original Medicare + Wisconsin Medigap + Part D — keeps Original Medicare, adds a state-standardized supplement (Basic Plan + riders), plus a drug plan.
⚠️ Switching from Advantage back to Medigap later usually requires health underwriting. The decision you make at 65 is the easiest one to change — but only during your guaranteed-issue window.
Track A: Medicare Advantage in the La Crosse area
Medicare Advantage plans bundle Part A, Part B, and usually Part D into one private plan — typically with a $0 or low monthly premium beyond your Part B premium, plus copays and a yearly out-of-pocket maximum.
What to check before choosing Advantage
Verify your primary care physician, any specialists, and your preferred hospital system (Gundersen or Mayo Clinic Health System) are in the plan's network. Networks change annually — don't assume last year's network applies this year.
Check every drug you take against the plan's drug formulary. Even $0-premium Advantage plans can have high copays for certain medications. The right formulary match often matters more than the plan premium.
Medicare Advantage plans must have an annual out-of-pocket maximum (MOOP). In 2025, the statutory maximum is $9,350 for in-network costs. Plans set their own MOOP below that limit. If you have a serious diagnosis, this number determines your worst-case year.
An HMO requires in-network providers and usually referrals for specialists. A PPO allows out-of-network care at higher cost without referrals. If you travel frequently or split time between Wisconsin and Minnesota, a PPO gives you more flexibility.
We check every available Advantage plan in La Crosse County and Winona County against your specific providers, prescriptions, and situation — at no cost to you.
Track B: Original Medicare + Wisconsin Medigap + Part D
This path keeps you on Original Medicare and fills the gaps with a Wisconsin-standardized Medicare Supplement (Medigap) policy, plus a standalone Part D drug plan.
The Wisconsin difference: Basic Plan + riders (not Plan G or Plan N)
Wisconsin does not use the national Medicare Supplement letter system (Plan A–Plan N). If you've read about Plan G or Plan N online, that framework applies in 47 other states — not Wisconsin.
Wisconsin's system:
- Basic Plan (mandatory in all WI Medigap policies): covers Part B 20% coinsurance, Part A hospital coinsurance for days 61–150, 365 additional lifetime hospital days, first 3 pints of blood, hospice care costs
- Optional riders stacked on top: Part A Deductible Rider ($1,676/benefit period, 2025), Part B Excess Charges Rider, Part B Deductible Rider, Foreign Travel Emergency, Home Health Care, and others
Most common combination (≈ national Plan G): Basic Plan + Part A Deductible Rider + Part B Excess Charges Rider. You pay only the Part B deductible (~$257/year) as your cost-sharing.
Your 6-month Medigap guaranteed-acceptance window
When you first enroll in Part B at 65, Wisconsin carriers must accept your Medigap application regardless of your health history — no underwriting, no exclusions, no higher premiums for pre-existing conditions. This window lasts exactly 6 months from your Part B effective date.
After the window closes: carriers can medically underwrite you and may decline coverage or charge higher rates based on your health. This is the most time-sensitive aspect of turning 65 — and the reason we encourage starting early.

Common turning-65 mistakes (and how to avoid them)
Only people already receiving Social Security benefits are auto-enrolled. Everyone else must actively apply. If you're not receiving Social Security at 65, you must sign up for Parts A and B yourself.
COBRA and ACA marketplace plans are not creditable coverage for delaying Medicare Part B. Relying on them after 65 to avoid enrolling in Part B creates a penalty. Only active employer group coverage (from a current employer with 20+ employees) counts.
Going without a Part D plan creates a permanent penalty for every month without creditable drug coverage — even if you're healthy now. A $15/month plan today prevents a lifelong surcharge if your health changes.
Switching from Medicare Advantage back to Original Medicare + Medigap after your guaranteed-acceptance window closes typically requires health underwriting in Wisconsin. If you have significant health conditions at that point, you may be declined or charged more. The decision at 65 matters most.
Wisconsin uses its own Medigap system — Basic Plan + optional riders. National websites, call centers, and out-of-state agents may use Plan G as shorthand for the Wisconsin equivalent, causing confusion. Work with a Wisconsin-licensed local advisor who knows the correct terminology and can compare carriers accurately.
Turning 65 Medicare FAQs
When exactly does my Medicare eligibility begin when I turn 65?
Your Medicare eligibility begins on the first day of the month you turn 65. Exception: if your birthday falls on the first day of a month, eligibility begins on the first day of the preceding month. Your Initial Enrollment Period (IEP) is a 7-month window: the 3 months before your birthday month, your birthday month itself, and the 3 months after.
What happens if I miss my Initial Enrollment Period?
If you don't enroll in Part B during your IEP without having creditable employer coverage, you face two consequences: (1) a permanent Part B late-enrollment penalty of 10% added to your premium for each full 12-month period you could have had coverage but didn't, and (2) you must wait for the next General Enrollment Period (January 1–March 31) with coverage starting July 1. We help you track your window precisely.
I'm still working at 65 with employer health coverage. Do I have to enroll in Medicare?
It depends on your employer size. If your employer has 20+ employees, your group plan is primary and Medicare is secondary — you can delay Part B penalty-free while covered by the employer plan. If your employer has fewer than 20 employees, Medicare is primary and delaying Part B can create gaps and penalties. This is one of the most nuanced Medicare decisions, and getting it wrong is costly. Call us before your 65th birthday to confirm the right move for your situation.
Does Wisconsin have Plan G or Plan N for Medicare Supplement?
No. Wisconsin uses its own state-standardized Medicare Supplement system — not the national A–N letter plans. Wisconsin residents choose a mandatory Basic Plan and add optional riders to customize coverage. The combination of Basic Plan + Part A Deductible Rider + Part B Excess Charges Rider provides functionally equivalent coverage to national Plan G. We explain the Wisconsin system in detail and compare every carrier.
Should I choose Medicare Advantage or Original Medicare + Medigap at 65?
Both paths are valid — the right choice depends on your health conditions, your providers (Gundersen, Mayo Clinic Health System), your prescriptions, and your travel patterns. Medicare Advantage has lower premiums but uses provider networks. Wisconsin Medigap costs more monthly but has no networks and predictable out-of-pocket costs. Switching from Advantage back to Medigap later usually requires health underwriting. The decision you make at 65 is easiest to change during your guaranteed-issue window, which is why we encourage making it thoughtfully from the start.
Do I need Part D drug coverage if I take no medications?
You should enroll in a low-cost Part D plan even if you currently take no medications. Going without Part D creates a permanent late-enrollment penalty — roughly 1% of the national base premium for each month without creditable drug coverage. A low-cost Part D plan for $10–$20/month now prevents a lifelong penalty if your health changes later.
How soon before turning 65 should I start the Medicare planning process?
Start 3 months before your 65th birthday month. That gives time to compare every plan available in La Crosse County or Winona County, verify your providers are in-network (for Advantage) or covered (for any plan), match your prescriptions to a Part D formulary, and have all paperwork done before your coverage effective date.
What is the Wisconsin Medigap Open Enrollment Period?
Your Medigap Open Enrollment Period is the 6-month window starting when you are both age 65 or older AND enrolled in Medicare Part B. During this window, Wisconsin carriers must accept your application regardless of health history. After this window closes, you typically face health underwriting and carriers may decline coverage. This window is why the timing of your Part B enrollment matters so much.
