Best Medicare Supplement Plans in North Dakota 2026

North Dakota Has No Birthday Rule: Your Initial Plan Choice Matters
Unlike California, Oregon, and other states with birthday rules, North Dakota does not give you an annual window to switch Medigap carriers without underwriting. Once your 6-month Open Enrollment Period ends, you will face health questions if you try to change plans. Compare carriers carefully before you enroll and consider long-term rate stability, not just today's lowest premium.
North Dakota has over 90,000 residents enrolled in Medicare Supplement Insurance, also called Medigap. The state follows standard federal Medigap rules, offering plans A through N with no state-specific modifications. Plan G is the most popular choice for new enrollees, covering nearly all Medicare out-of-pocket costs except the annual Part B deductible ($283 in 2026).
North Dakota does not have a birthday rule or anniversary rule, which means your 6-month Open Enrollment Period when you first turn 65 and enroll in Part B is your best and most important opportunity to lock in coverage. After that window closes, carriers can use medical underwriting to deny your application or charge higher premiums based on your health history.
Plan G premiums in Fargo range from $127/mo (Mutual of Omaha) to $218/mo (AARP/UHC) for a 65-year-old. Sanford Health Plan is the dominant local carrier in North Dakota, offering integrated coverage with the Sanford Health system across Fargo, Bismarck, and Grand Forks. State Farm stands out with an A++ AM Best rating and a local agent network statewide.

Plan G vs. Plan N in North Dakota
Plan G and Plan N are the two most popular Medigap plans for new enrollees in North Dakota. Plan G offers more complete coverage; Plan N costs less each month but includes small copays.
| Benefit | Plan G | Plan N |
|---|---|---|
| Part A hospital coinsurance | Covered | Covered |
| Part B coinsurance (20%) | Covered | Covered* |
| Part A deductible ($1,736) | Covered | Covered |
| Part B deductible ($283) | Not covered | Not covered |
| Part B excess charges | Covered | Not covered |
| Skilled nursing coinsurance | Covered | Covered |
| Foreign travel emergency | Covered | Covered |

North Dakota Medigap Rules You Should Know
No Birthday Rule in North Dakota
North Dakota does not have a birthday rule. Once your 6-month Open Enrollment Period ends, you will face medical underwriting if you try to switch carriers or plans. Your initial enrollment decision is the most important one you will make.
Attained-Age Pricing is the Dominant Method
Most North Dakota carriers use attained-age pricing, which means your premium increases as you get older. Transamerica is a notable exception, offering issue-age pricing that locks your rate at enrollment age.
Open Enrollment Period: 6 Months Starting at 65
Your Medigap Open Enrollment Period begins the month you turn 65 and enroll in Medicare Part B. During this 6-month window, no carrier can deny you coverage or charge higher rates due to health conditions.
Plan F Closed to New Enrollees Since 2020
Plan F is only available if you were eligible for Medicare before January 1, 2020. New enrollees must choose Plan G or another available plan.
Under-65 Medigap Coverage Not Required
North Dakota does not require carriers to offer Medigap to Medicare beneficiaries under age 65. If you have Medicare due to disability before age 65, you may have limited options and higher premiums.

MedicareFAQ Scoring Methodology
The MedicareFAQ Score rates Medicare Supplement carriers on a scale of 1.0 to 5.0 based on five key factors. Our ratings are independent and not influenced by advertising relationships.
Financial Strength (AM Best Rating)
AM Best ratings from A++ to A- indicate the carrier's ability to pay claims. We weight this heavily because Medigap is a long-term product.
Premium Competitiveness
Plan G and Plan N rates compared to the North Dakota state average. Lower premiums relative to the market earn higher scores.
Customer Satisfaction and Complaint Ratio
NAIC complaint index scores and J.D. Power ratings. Lower complaint ratios indicate better claims handling and customer service.
Pricing Method Stability
Issue-age and community-rated plans score higher than attained-age plans because premiums are more predictable over time.
Plan Availability and Discounts
Carriers offering more plan types and household discounts (typically 5-7% for two people in the same household) score higher.
