Medigap plans help cover out-of-pocket costs that Original Medicare doesn't — like deductibles, coinsurance, and copayments. Minnesota has its own unique Medigap structure.
Minnesota is one of only three states (along with Massachusetts and Wisconsin) that standardize Medigap plans differently from the "lettered" plans used in most other states. Minnesota's Medigap is built around a Basic Plan and an Extended Basic Plan, with optional riders.
Minnesota's Basic Medigap plan covers core out-of-pocket costs:
The Basic Plan does not automatically cover the Part A inpatient deductible or Part B excess charges — these require optional riders. Note: Medigap policies cannot cover the Part B deductible for individuals who became Medicare-eligible on or after January 1, 2020.
The Extended Basic Plan includes all Basic benefits plus:
A popular middle-ground option
The Plan N Co-Pay Option (PBCO) — sometimes called Plan N — is a real and widely-used alternative that sits between the Basic Plan and Extended Basic. It covers most of the same core benefits as Extended Basic, but instead of paying 100% of everything, you share a small portion of costs through fixed copayments. In exchange, the monthly premium is meaningfully lower.
Starting August 1, 2026, Minnesotans age 65–70 can enroll in a Medigap plan without medical underwriting during a special annual window aligned with the fall Annual Election Period. This is a "second chance" for those who missed their original Medigap window.
However, using this right comes with a premium surcharge that applies for the duration of the policy:
The best time to enroll is during your 6-month Medigap Open Enrollment Period — starting the first month you have Part B and are 65+. During this window, insurers cannot deny you or charge more based on health. After this window, medical underwriting typically applies.
