Most individuals become eligible for Medicare enrollment when they turn 65. But younger individuals gain Medicare eligibility after they have been receiving disability benefits for 24 months, or if they have end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS). In New Hampshire, about 10% of Medicare beneficiaries are under 65 and eligible due to disability rather than age.1

Medicare supplement (Medigap) plan availability in New Hampshire
There were 99,250 New Hampshire residents with Medigap coverage as of 2023, according to an AHIP report.5
There were 23 insurers in New Hampshire approved to offer Medigap plans as of 2026.6
The state of New Hampshire maintains a Medigap rate comparison tool that residents can use to see pricing, benefits information, and plan availability.
Unlike other Medicare plan coverage (Medicare Advantage and Medicare Part D prescription drug plans), there is no Medicare Annual Open Enrollment window for Medigap plans. Instead, federal rules provide a one-time six-month window when Medigap coverage is guaranteed-issue. This window starts when a person is at least 65 and enrolled in Medicare Part B. (You must be enrolled in both Part A and Part B to buy a Medigap plan.) Once that initial enrollment window ends, Medigap insurers in nearly all states can use medical underwriting to determine an applicant’s eligibility for coverage, unless one of the limited guaranteed-issue rights applies.
New Hampshire lawmakers have considered some bills in the last several years that would have expanded Medigap consumer protections, plan change options, etc., including SB646 in 2020 and HB774 in 2025. But neither of those bills passed.
SB124, which initially included a “birthday rule” provision, was enacted in 2021. But the birthday rule guaranteed issue provision was removed from the bill during the legislative process, and the bill ultimately only ensured that Medigap insurers could not continue to charge the higher under-65 rates once a disabled Medigap enrollee turns 65.
Is Medigap available if you are under 65 in New Hampshire?
People who aren’t yet 65 can enroll in Medicare if they’re disabled and have been receiving disability benefits for at least two years, or if they have end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS); about 10% of New Hampshire Medicare beneficiaries are under age 65.7 Federal rules do not guarantee access to Medigap plans for people who are under 65, but the majority of the states have implemented rules to ensure that disabled Medicare beneficiaries have at least some access to Medigap plans. New Hampshire was among the first states to require Medigap insurers to offer plans to people under age 65, with a rule that took effect in the late 1990s. The state’s requirements were reiterated in a 2005 bulletin issued by the New Hampshire Insurance Department.8
All Medigap plans in New Hampshire are available to disabled enrollees under age 65, as long as they enroll during the six-month window that begins when they’re enrolled in Medicare Part B. Premiums are higher than the age-65 rates for these enrollees – substantially so for some insurers, and modestly higher for others.9 Disabled Medicare beneficiaries have another Medigap Open Enrollment Period when they turn 65. At that point, they can switch to a plan with the lower premiums that apply to people who are aging into Medicare, rather than qualifying due to disability. And SB124, enacted in 2021, prohibits Medigap insurers from continuing to charge the higher premiums once a disabled enrollee turns 65. So regardless of whether the person switches to a different plan or keeps the plan they already have, their Medigap rates will reset to the lower age-65 rates once they turn 65.
