Medicare Supplement Plans (Medigap)
Medicare Supplement Plans (Medigap)
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.
Medicare Supplement, also called Medigap, is private insurance that covers out-of-pocket costs Original Medicare doesn't — like copays, coinsurance, and deductibles.
Minnesota Medigap — Different from Most States
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.
Basic Plan
Minnesota's Basic Medigap plan covers core out-of-pocket costs:
- Part A and Part B coinsurance and copayments
- Up to 100 days of skilled nursing facility care per benefit period
- The first three pints of blood each year
- 80% of emergency care outside the U.S.
- State-mandated benefits (diabetic supplies, routine cancer screening, etc.)
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.
Extended Basic Plan
The Extended Basic Plan includes all Basic benefits plus:
- 100% of the Medicare Part A inpatient hospital deductible
- 100% of Part A and B coinsurance
- Up to 120 days of skilled nursing facility care per benefit period
- 100% of Part B excess charges
- 80% of emergency care outside the U.S.
- 100% of immunizations not covered by Part D
- 100% of routine cancer screening (mammograms and pap smears)
- A $120/year preventive medical care benefit for non-Medicare-covered preventive services
- Hospice and respite cost sharing
- Home health cost sharing
- First 3 pints of blood
PBCO / Plan N — Basic with Copays
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.
- Part A inpatient hospital deductible — covered 100%
- Part A and Part B coinsurance — covered 100%
- Up to 100 days of skilled nursing facility care per benefit period
- 80% of emergency care outside the U.S.
- Part B excess charges — NOT covered (you pay the difference if a provider doesn't accept Medicare assignment)
New Minnesota Medigap Law (Effective August 1, 2026)
Minnesota law now provides additional Medicare Supplement open enrollment opportunities for eligible Minnesotans outside their original six-month Medigap enrollment period. The applicable enrollment periods are defined under Minnesota law by reference to specified Medicare enrollment periods. Eligible applicants may enroll without medical underwriting during these periods, although certain first-time applicants ages 65 through 70 who enroll outside their original Medicare Part B enrollment period may be subject to a statutory premium increase.
However, using this right comes with a premium surcharge that applies for the duration of the policy:
- 15% extra if you first enroll in 2026
- 20% extra in 2027
- 25% extra in 2028
- 30% extra in 2029
- 35% extra for 2030 and all later years
Another option worth knowing
High Deductible Medicare Supplement
A high-deductible plan carries a lower monthly premium — $2,950 deductible for 2026 — and lets you build targeted protection around it with hospital indemnity, cancer, or accident coverage. It's designed for people who want to control their costs and see any provider they choose.

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.
