Why Wisconsin Medicare Supplement Plans Don't Use Letters Like Plan G or Plan N

By Brad Loose, Independent Insurance Agent · Kimberly, WI

Search "best Medicare Supplement plan" online and you'll see article after article talking about Plan G and Plan N. If you're in Wisconsin, none of that applies to you — and it's one of the most common points of confusion Brad hears from new Medicare beneficiaries.

Wisconsin Doesn't Use the Lettered Plan System

Wisconsin, Massachusetts, and Minnesota are the only three states that don't use the federal government's standardized, lettered Medigap plans. Instead, Wisconsin requires every insurer to offer a state-mandated Basic Plan, and you build coverage up from there with optional riders.

What the Basic Plan Covers Automatically

The Optional Riders You Can Add

From there, you choose which gaps to fill:

There's also a High-Deductible Plan option in Wisconsin, where you pay a calendar-year deductible ($2,950 in 2026) before the plan starts paying, in exchange for a much lower monthly premium.

Why This System Actually Works in Your Favor

The modular approach means you're not paying for coverage you don't need. Someone who travels internationally every winter has very different priorities than someone who rarely leaves the Fox Valley — Wisconsin's system lets you build a policy around your actual life instead of picking from a one-size-fits-all lettered menu.

The tradeoff is that comparing quotes takes a little more explanation than "just get Plan G," which is exactly why it helps to work with an agent licensed in Wisconsin who deals with this structure daily.
