Medicare Supplement Plans in Wisconsin: 2026 Guide
Wisconsin uses its own plan designs rather than federal standard letters. Plans include "Basic" and optional add-on benefits. Community rating applies.
Plan G vs Plan N in Wisconsin: 2026 Premiums
The two most popular Medigap plans in Wisconsin are Plan G and Plan N. Here's how they compare:
| Feature | Plan G | Plan N |
|---|---|---|
| Average monthly premium (age 65) | $138/mo | $110/mo |
| Premium range (age 65) | $110–$215/mo | $88–$172/mo |
| Part B deductible ($283/yr) | You pay | You pay |
| Doctor visit copay | None | Up to $20 |
| Emergency room copay | None | Up to $50 (waived if admitted) |
| Part B excess charges | Covered | Not covered |
| Foreign travel emergency | 80% (after $250 deductible, up to $50K) | 80% (after $250 deductible, up to $50K) |
| Monthly savings vs Plan G | N/A | ~$28/mo |
Premiums are averages for a 65-year-old non-smoking female. Actual rates vary by insurer, age, gender, and tobacco use. Always compare multiple quotes.
Community Rating in Wisconsin
Wisconsin uses community rating, which means every policyholder pays the same premium for the same plan, regardless of age or health status. This is the most consumer-friendly rating method. Older beneficiaries in particular benefit because their premiums are not higher simply due to their age. Premiums may still increase over time due to medical inflation, but not because you're getting older.
Guaranteed-Issue Rights in Wisconsin
Wisconsin has its own unique Medigap plan designs and uses community rating. Guaranteed-issue protections are stronger than the federal minimum.
The most important guaranteed-issue period for most people is the Initial Enrollment Period (IEP): the 6-month window that begins when you are both age 65 (or older) and enrolled in Medicare Part B. During this window, all insurers must accept your application at their standard rates regardless of your health history.
Wisconsin Plan G Costs in Context
At an estimated $138/month for a 65-year-old, Plan G in Wisconsin ranks #27 of 51 among states and DC from lowest to highest cost, sitting 2% above the national median of $135/month in our dataset. Wisconsin is home to about 1,280,000 Medicare beneficiaries (#19 by enrollment), so the number of active insurers can be more limited than in the largest states.
Wisconsin uses community rating, so everyone in the state pays the same premium for the same plan regardless of age. The figure shown here should stay comparable whether you enroll at 65 or later, apart from general premium trends.
Plan G vs Plan N break-even in Wisconsin
Plan N costs about $28 less per month than Plan G here, or roughly $336 a year. Because Plan N can charge up to $20 per office visit and up to $50 per emergency room visit that does not lead to admission, that saving is used up after about 16 office visits or 6 ER visits in a year (the copays are maximums, so real-world break-even is often a little higher). Plan N also does not cover Part B excess charges.
| Care use in a year | Plan G total | Plan N total (max copays) | Lower cost |
|---|---|---|---|
| Light use: 2 office visits, no ER | $1,939 | $1,643 | Plan N |
| Typical use: 6 office visits, no ER | $1,939 | $1,723 | Plan N |
| Regular use: 12 office visits, 1 ER visit | $1,939 | $1,893 | Plan N |
| Heavy use: 20 office visits, 2 ER visits | $1,939 | $2,103 | Plan G |
Totals add twelve months of the estimated age-65 premium to the $283 Part B deductible (2026) that both plans leave to you, plus Plan N copays at their maximum. They exclude Part B premiums and Part D. Actual quotes vary by insurer, age, gender, and tobacco use.

Enrollment Tips for Wisconsin Residents
- Enroll during your open enrollment window. The 6-month window starting when you first get Part B at 65 is your best chance, guaranteeing acceptance at standard rates.
- Compare at least 3 quotes. Premiums for identical coverage can vary by 30–50% between insurers. Use a licensed broker or comparison tool.
- Ask about rate history. In attained-age states like most, ask each carrier for their 5-year rate increase history before committing.
- Consider your typical healthcare usage. Frequent users benefit most from Plan G; occasional users can often save with Plan N.
- Factor in age increases. Plan G at $150/month at 65 may cost $200+ at 75 under attained-age rating. Project forward before deciding.

What is the best Medicare Supplement plan in Wisconsin?
Plan G is the most popular Medicare Supplement plan in Wisconsin and nationally. It covers everything Medicare doesn't pay except the Part B deductible ($283 in 2026). For budget-conscious beneficiaries comfortable with small copays, Plan N, which costs roughly $28/month less than Plan G in Wisconsin, is an excellent alternative. The "best" plan depends on your health, budget, and how often you use medical services.
How much does Medicare Supplement cost in Wisconsin?
Average Plan G premiums in Wisconsin for a 65-year-old non-smoking female range from approximately $110–$215/month, with a typical starting rate around $138/month in 2026. Plan N averages $110/month at age 65. Premiums vary by insurer, your exact age, gender, and tobacco use. Always compare quotes.
What rating method does Wisconsin use for Medicare Supplement?
Wisconsin uses community rating, meaning all policyholders pay the same premium regardless of age. This benefits older beneficiaries who would pay more under attained-age systems. Premiums may still increase due to medical inflation, but not because you're getting older.
Does Wisconsin have a Medigap Birthday Rule?
No, Wisconsin does not currently have a Birthday Rule. Outside of your initial 6-month open enrollment period (when you first enroll in Medicare Part B), you can generally only switch Medigap plans if you qualify for a Special Enrollment Period or can pass medical underwriting.
When is the best time to enroll in Medicare Supplement in Wisconsin?
The best time to enroll is during your Initial Enrollment Period (IEP): the 6 months starting the month you turn 65 AND are enrolled in Medicare Part B. During this window, insurers must accept you regardless of health status at their best available rates. After this window closes, you may be subject to medical underwriting in most states.
