How pricing works in New Hampshire
Most carriers in this state use attained-age rating, so premiums rise as you get older. Issue-age and community-rated policies may also be offered.
A community-rated plan charges the same monthly premium regardless of age. Issue-age plans lock your premium based on the age you bought in. Attained-age plans start lower in your 60s and rise as you get older. Over a 20-year horizon, the rating method usually matters more than the plan letter.
Switching Medigap plans in New Hampshire
Federal law gives you a 6-month Medigap Open Enrollment Period that starts the month your Part B begins. During that window any Medigap carrier in New Hampshire must sell to you with no medical underwriting. After it closes, federal guaranteed-issue rights only trigger in specific situations (for example, when your employer plan ends or a Medicare Advantage plan leaves your area).
New Hampshire does not currently add a state-level birthday or anniversary rule. If you want to switch outside a federal guaranteed-issue right, expect underwriting.
