What Are the Best Medicare Supplement Plans in Wisconsin?

Choosing a Medicare Supplement (Medigap) plan in Wisconsin can feel overwhelming. There are multiple options, different price points, and rules that are unique to Wisconsin compared to most other states. This guide breaks it all down in plain English so you can make a smart, confident decision.

How Wisconsin Medigap Works Differently Than Other States

Most states follow a federal standardization system where Medigap plans are labeled by letters — Plan G, Plan N, Plan F, and so on. Wisconsin is one of only three states (along with Massachusetts and Minnesota) that uses its own standardization system.

Instead of lettered plans, Wisconsin offers:

• Basic Plan — The foundation of all Wisconsin Medigap policies
• Optional riders — Add-on benefits you can attach to the Basic Plan
• 50% cost-sharing plan — A lower-premium option where you share some costs
• 25% cost-sharing plan — Another budget-friendly option with shared costs

The Wisconsin Basic Plan already covers quite a bit, including Medicare Part A hospital costs, skilled nursing coinsurance, and 175 days per lifetime of inpatient mental health care. You then choose riders to fill in any remaining gaps.

What Does the Wisconsin Basic Medigap Plan Cover?

The Basic Plan is the starting point for almost every Wisconsin resident buying a Medigap policy. Here is what it typically includes:

• Inpatient hospital costs after Medicare Part A benefits are used
• 365 lifetime reserve hospital days
• Skilled nursing facility coinsurance (days 21–100)
• Medicare Part B coinsurance (usually 20% of outpatient costs)
• Three pints of blood per year
• Hospice care coinsurance

What the Basic Plan does not automatically cover includes the Medicare Part A deductible, the Medicare Part B deductible, and foreign travel emergency care. Those gaps can be filled with optional riders.

Most Popular Optional Riders in Wisconsin

Riders are what make Wisconsin's system flexible. You pick and choose what you want to add onto your Basic Plan. Common riders include:

• Part A deductible rider — Covers the hospital deductible (in 2024, this is $1,632 per benefit period)
• Part B deductible rider — Covers the annual Part B deductible (note: if you became eligible for Medicare after January 1, 2020, you may not be able to purchase this rider — confirm with your insurer)
• Excess charges rider — Pays the difference if a doctor charges more than Medicare's approved amount
• Foreign travel emergency rider — Covers urgent medical care when traveling outside the U.S.
• Home health care rider — Adds extra home health visit benefits
• Preventive care rider — Covers preventive services not included under standard Medicare

The more riders you add, the more comprehensive your coverage — and the higher your monthly premium.

How Much Do Wisconsin Medigap Plans Cost?

Premiums vary based on several factors:

• Your age — Older enrollees generally pay higher premiums
• Your ZIP code — Urban vs. rural pricing can differ
• The insurance company — Every insurer prices their own way
• Tobacco use — Smokers may pay more
• Riders selected — More add-ons mean higher monthly costs

A basic plan with no riders might cost significantly less per month than a plan loaded with riders. On average, Wisconsin Basic Plans without riders can start in the range of $80–$150/month for a 65-year-old, but this varies widely. Always compare quotes from multiple insurers before deciding.

When Can You Enroll in a Wisconsin Medigap Plan?

The best time to enroll is during your Medigap Open Enrollment Period, which starts the month you are both 65 years old AND enrolled in Medicare Part B. During this 6-month window, insurers cannot deny you coverage or charge you more because of pre-existing conditions.

After that window closes, you may face medical underwriting — meaning insurers can review your health history and potentially deny coverage or charge higher premiums.

Wisconsin does have some additional consumer protections beyond federal rules. For example, Wisconsin law requires insurers to offer a guaranteed-issue period in certain situations, such as when you lose other coverage. Specifics vary — confirm with your insurer or a licensed advisor.

How to Compare Plans and Insurers in Wisconsin

Here are practical steps to find the best fit:

1. List your health priorities — Do you travel internationally? Do you see specialists often? Do you want predictable costs?
2. Decide on riders — Start with the Basic Plan and add riders based on your priorities
3. Get multiple quotes — The same benefits can cost very different amounts depending on the insurer
4. Check financial ratings — Look for insurers rated A or better by AM Best for financial stability
5. Review annual increases — Ask about rate history before you commit

Frequently Asked Questions

Is Medicare Advantage the same as Medicare Supplement in Wisconsin?

No. Medicare Advantage (Part C) replaces Original Medicare and is run by private insurers. Medicare Supplement (Medigap) works alongside Original Medicare to cover cost-sharing gaps. They serve different purposes and you generally cannot have both at the same time.

Can I be denied a Medigap plan in Wisconsin?

During your Open Enrollment Period, no — insurers must accept you regardless of health status. Outside that window, insurers may use medical underwriting and can deny coverage or charge more. Certain life events may trigger a guaranteed-issue right. Check with a licensed advisor for your specific situation.

Does Wisconsin have any unique Medigap rules I should know about?

Yes. Wisconsin uses its own standardization system instead of the federal lettered-plan model. Wisconsin also has some additional consumer protections under state law. Always confirm current rules with the Wisconsin Office of the Commissioner of Insurance (OCI) or a licensed Medicare advisor.

What happens to my Medigap plan if I move out of Wisconsin?

Most Medigap policies are portable — meaning your coverage generally follows you. However, you may want to review your plan options in your new state, since plan structures differ. Contact your insurer before moving to understand your options.

Does my Medigap plan cover prescription drugs?

No. Wisconsin Medigap plans do not cover prescription drugs. For drug coverage, you need to enroll separately in a Medicare Part D prescription drug plan.
