Best Medicare Supplement Plans in Wisconsin (2026)

AFLAC and State Farm are Wisconsin's best Medicare Supplement plan providers. AFLAC costs $161 monthly, $41 below the $202 state average, with premiums rising $55 to reach $216 by age 75. State Farm costs $178 monthly, $24 below the same average, and includes 40 home care visits per year that no other featured carrier provides.

MedMutual Protect is Wisconsin's cheapest at $145 monthly, $57 below the $202 state average, with the lowest age-75 rate of any featured carrier at $181. If the lowest premium is the only goal, compare MedMutual Protect first against other carriers for your ZIP code. AFLAC and State Farm have broader plan availability and more coverage options statewide.

Bankers Life at $216 monthly rises to $309 at 75, the sharpest increase among featured carriers and the only one above the $202 state average.

*These Medicare Supplement rates reflect Wisconsin's Medigap Basic Plan for 65-year-old and 75-year-old beneficiaries. The Basic Plan is the most popular option and the only standardized plan required by Wisconsin law. Your actual premium varies based on age, ZIP code and optional riders you add.

Wisconsin's four plan types trade monthly premiums against what you pay when you need care. A lower premium comes with a higher financial commitment before benefits begin. The High Deductible plan's $76 monthly average means clearing a $2,950 deductible first. At $202 monthly, the Basic Plan has no plan-level deductible, so coverage begins from your first eligible claim.

A High Deductible plan saves $1,512 annually in premiums over the Basic Plan. But one hospitalization that clears the $2,950 deductible costs you more than the Basic Plan's full year of premiums. If you expect regular medical care or any hospitalizations, the Basic Plan is the lower-risk choice.

Wisconsin uses a different system from the standard Plans A through N sold in other states. Every Wisconsin Medigap policy starts with the same state-mandated Basic Plan. From there, enrollees can add optional riders or select a cost-sharing structure.

Wisconsin doesn't use the standard plan letters you'll see in other states. Wisconsin also mandates $30,000 yearly kidney disease coverage and 40 extra home health visits on every Basic Plan, so you don't need a rider for either.

Wisconsin insurers price the Basic Plan differently based on their rating method. Most Wisconsin insurers use attained-age pricing, where premiums rise annually as you get older. A few carry community-rated pricing, where all policyholders pay the same monthly rate regardless of age. When comparing carriers below, check both the starting rate at 65 and the age-75 rate to see which costs less over time.

*These Medicare Supplement rates reflect 2026 pricing for Wisconsin's Medigap Plan for 65 and 75-year-olds. Wisconsin offers unique structures including the Basic Plan, 50% and 25% Cost Sharing plans, and High Deductible options. Premiums vary by plan type, age, insurer and rating method (attained-age, issue-age or community rating).

Wisconsin residents deal with a Medigap system unlike the rest of the country. Instead of standardized Plans A through N, Wisconsin requires insurers to provide four plan types with varying cost-sharing structures, so if you choose between 25% cost sharing, 50% cost sharing, basic coverage or high-deductible options without guidance can leave you overpaying or with coverage gaps. We built our analysis around Wisconsin's system to identify which insurers provide the strongest value for your health care needs and budget.

Our Research Approach 
We evaluated 22 Wisconsin Medigap insurers across three factors. Rate data covers all four Wisconsin plan types and is current as of August 2026.

• Affordability (50%): In our Wisconsin data, the difference between the cheapest and most expensive attained-age Basic Plan carrier at age 65 is $161 monthly, a gap that compounds to nearly $2,000 annually for identical coverage. That's why affordability carries the heaviest weight in our scoring.
• Pricing style (20%): Under community rating, which some Wisconsin carriers use, your premium stays the same regardless of age. Attained-age products raise premiums annually, so pricing style directly affects your 10-year cost trajectory.
• Plan availability (30%): Wisconsin requires four plan types. Insurers providing all four earn higher scores. Enrollees managing chronic conditions or frequent hospitalizations are better served by the Basic Plan, which limits what you pay per claim compared to the High Deductible plan.

Sample Consumer Profile

Monthly premiums reflect rates for a 65-year-old Wisconsin resident using attained-age pricing, where premiums rise annually with age. The Basic Plan is Wisconsin's most popular option and requires no cost-sharing after the $283 Part B deductible, the annual fee Medicare charges before covering outpatient costs. We collected 2026 pricing across all four plan types from 22 insurers operating statewide.
