Medicare Supplement Plans (Medigap) in New Hampshire 2026

Key New Hampshire 2026 Takeaways

• Provider Network Freedom: Medigap policies give you total freedom to visit any physician or hospital in New Hampshire—or across the nation—that accepts Medicare for Medicare-approved services, without ever needing a referral.
  

• 2026 Premium Baselines: Average monthly premiums for a 65-year-old New Hampshire resident range between $203 and $229, though exact costs depend on your specific age, gender, tobacco use, and local regional location.
  

• Enrollment Timing Protection: Enrolling during your initial six-month Open Enrollment window protects you from invasive health screenings and prevents insurance carriers from raising your rates due to pre-existing conditions.

What is a Medicare Supplement plan in New Hampshire?

A Medicare Supplement policy acts strictly as a secondary payer. This means Original Medicare pays its required share of the cost of your covered medical service first. After that, your Medigap policy pays its portion to handle remaining out-of-pocket Medicare-approved expenses, such as your 20% Part B coinsurance.

It is important to remember that Medigap policies are individual accounts. Spouses cannot share a policy, meaning married couples must purchase separate individual plans.

Important Consumer Notice from the New Hampshire Insurance Department: Applicants should never pay Medigap premiums using cash. Payments must always be processed using a personal check, money order, or automatic bank transfer made payable directly to the insurance carrier—never to an individual insurance agent.

Types of Medicare Supplement Plans Offered in New Hampshire

New Hampshire offers standardized Medigap plans labeled with letters A through N. Standardized means that Plan G offered by one insurance carrier delivers the exact same medical coverage benefits as Plan G sold by another carrier. Premium prices and customer perks are usually the main differences between insurers.

Plan C and Plan F cover the Medicare Part B deductible, but federal regulations state that these plans are no longer available to individuals who became newly eligible for Medicare on or after January 1, 2020. If you were enrolled in Plan C or Plan F prior to 2020, you are grandfathered in and can keep your coverage.

Most Popular Medicare Supplement Insurance Plans in New Hampshire

According to AHIP survey data, tens of thousands of New Hampshire beneficiaries rely on standardized Medigap coverage. Two specific options represent the vast majority of new enrollments today:

• Plan G: It is considered the leading choice for comprehensive financial protection. It covers all Medicare cost gaps except for the annual Medicare Part B deductible ($283 in 2026). Once you pay that small annual deductible, Plan G covers 100% of your remaining Medicare-approved medical bills for the year.
  

• Plan N: This plan is a popular, budget-friendly option with lower monthly premiums. In exchange for lower rates, you pay modest copayments at certain doctor visits (up to $20) and emergency room visits (up to $50 if not admitted), while also paying the annual Part B deductible.
  

2026 New Hampshire Market Disruption Alert

• Advantage Market Volatility: Recent administrative updates and shifting carrier networks have caused major changes across the region. Widespread cancellations of private Medicare Advantage plans and carrier withdrawals are leaving many New Hampshire residents seeking new coverage options.
  

• Guaranteed Issue Rights: If your Medicare Advantage plan closes or stops serving your county, you receive a special, federally protected guaranteed issue right. This allows you to switch back to Original Medicare paired with an eligible Medigap plan without answering medical health questions or undergoing health background checks.
  

• Part D Drug Cost Capping: These market changes align with new federal prescription drug updates under the Inflation Reduction Act, which places a strict $2,100 annual out-of-pocket cap on prescription medications for Medicare beneficiaries.

Which New Hampshire senior are you?

• The Predictable Health Budgeter Senior: If you prefer total peace of mind and hate unexpected medical bills, Plan G is often your ideal match. You pay your fixed monthly premium and a small annual deductible, making your total healthcare expenses clear and predictable.
  

• The Premium Optimizer Senior: If you are generally healthy, visit the doctor only a few times per year, and prefer lower fixed monthly costs, Plan N fits your style well. Paying a nominal copay at the clinic keeps your monthly rates significantly lower over time.
  

• The Displaced Advantage Member: If your prior Medicare Advantage plan was canceled due to regional carrier exits in southern or rural New Hampshire, you can use your guaranteed issue window to transition into stable, reliable traditional Medicare paired with Medigap coverage.
