Medicare in Wisconsin works the same as nationwide — it is administered by the federal government through the Centers for Medicare & Medicaid Services (CMS). However, several important aspects of Medicare vary by state, including the number and quality of Medicare Advantage plans available, Medigap regulation, and state-specific assistance programs.
In Wisconsin, there are approximately 41 Medicare Advantage plans available in 2026, compared to a national average of around 40 plans per area. The average MA premium in Wisconsin is $13/month. Fewer plan options mean less competition, but Wisconsin seniors can still find quality Medicare Advantage coverage. Use our comparison tool above to evaluate whether Advantage or Original Medicare better fits your needs.
Medigap (Medicare Supplement) insurance in Wisconsin follows standard federal rules. Insurers use attained-age rating in most cases, meaning premiums increase as you age. Your best opportunity to buy Medigap is during your 6-month open enrollment period — the 6 months starting the first month you have Part B and are 65 or older. During this window, insurers cannot deny coverage or charge more due to health conditions.
Margaret is 64 and will turn 65 in March 2026, becoming eligible for Medicare in Wisconsin. She worked for 30+ years paying Medicare taxes (so Part A is free). Her 2024 MAGI was $88,000 (single filer — below the $106,000 IRMAA threshold).
If Margaret chose Medicare Advantage instead: average premium in Wisconsin is $13/month. Her total MA cost would be $198/month (Part B + MA premium), saving her approximately $209/month compared to Original Medicare with Medigap. However, she would face network restrictions and copays for services.

Income-Related Adjustments (IRMAA)
Your Part B premium is the same regardless of which state you live in — it's determined by your income. In 2026, singles earning over $106,000 (or couples over $212,000) pay IRMAA surcharges on top of the standard $185/month Part B premium. IRMAA is based on your 2024 tax return. If your income has decreased due to retirement or a life event, you can appeal the surcharge using SSA Form SSA-44.
Medigap Underwriting in Wisconsin
In Wisconsin, Medigap premiums typically use attained-age rating, meaning your premium increases each year as you age. Buying a Medigap policy at 65 during your open enrollment window locks in your best rate — you may not be able to buy or switch plans at the same rate later if your health changes.
