Medicare Supplement (Medigap) plans in New Hampshire help cover the costs that Original Medicare doesn't pay — including deductibles, copayments, and coinsurance.

How Medigap Pricing Works in New Hampshire
Since Medigap benefits are standardized, the only differences between insurers are price, financial stability, and customer service. Insurers in New Hampshire can price the same plan very differently, so comparing multiple carriers before you buy is essential.
3 Pricing Methods Used in New Hampshire
- Community-rated:Same premium for everyone regardless of age. Premiums may increase due to inflation but not because you get older.
- Issue-age-rated:Premium based on your age when you first buy the policy. Locked in at that age-based rate, then increases only with inflation.
- Attained-age-rated:Premium based on your current age, increasing every year as you get older. Starts lowest but becomes the most expensive over time.
When to Enroll in New Hampshire
The best time to buy a Medigap plan in New Hampshire is during your Medigap Open Enrollment Period — the 6-month window that begins the month you turn 65 and are enrolled in Medicare Part B. During this window, insurers cannot deny coverage or charge more based on your health history.
Outside this window, insurers in most states can use medical underwriting, meaning your health could affect your eligibility or price. Enroll on time.
Medigap vs. Medicare Advantage in New Hampshire
Medicare Advantage (Part C) is a popular alternative to Medigap in New Hampshire. Advantage plans often have lower monthly premiums (sometimes $0) but use provider networks. Medigap lets you see any Medicare-accepting doctor nationwide without referrals.
