Medicare Supplement Insurance Plans in Hawaii
Medicare Supplement Plans (Medigap) in Hawaii 2026
Medicare Supplement insurance plans, also known as Medigap, are private insurance options designed to help cover the out-of-pocket costs left by Original Medicare (Parts A and B). These gaps include out-of-pocket costs like deductibles, copayments, and coinsurance. Medigap works directly alongside your government benefits, acting strictly as a secondary payer anywhere in the United States that accepts Medicare.
This structure is completely different from private Medicare Advantage plans. Advantage plans replace the administration of your Original Medicare benefits through a private carrier's restricted provider network and often require prior referrals. Medigap gives you the freedom to choose your doctors without network limitations.
Key Hawaii 2026 Takeaways
Mainland and Inter-Island Portability: If you live on a neighbor island and need to travel to Honolulu for specialist care, or if you fly to California or the mainland for treatments, Medigap offers total portability with no out-of-network penalties.
100% Standardized Benefits: A Medigap Plan G from a local Hawaiian insurance company provides the exact same medical benefits as Plan G from a national insurance company. That means price, customer support, and company stability are your primary deciding factors.
Strict Enrollment Windows: Hawaii does not have a state-specific Birthday Rule or continuous open enrollment. Enrolling during your six-month initial enrollment period is critical to securing coverage without answering health questions.

What is a Medicare Supplement plan in Hawaii?
A Hawaii Medicare Supplement plan acts strictly as a secondary payer. Original Medicare pays its approved share of your medical costs first, and then your Medigap policy pays its portion of the remaining balance, such as your 20 percent Part B coinsurance.
While these plans provide great financial protection, it's essential to understand their scope:
No Drug Coverage: Hawaii Medigap plans cover medical and hospital gaps, but they don't include prescription drug coverage. You'll need a separate, standalone Medicare Part D plan for your daily medications.
Financial Protection: A Medigap plan shields your hard-earned retirement savings from unpredictable medical bills in a state with an exceptionally high cost of living.

Types of Medicare Supplement Plans Offered in Hawaii
The federal government standardizes Medigap plan options, which are labeled using letters A through N. Every standardized plan with the same letter must offer the exact same basic benefits, regardless of which insurance carrier sells it.
Older options, such as Plan C and Plan F, are no longer available to individuals who became newly eligible for Medicare on or after January 1, 2020. However, if you were enrolled in Plan C or Plan F prior to that date, you're grandfathered in and can keep your policy.
You can learn more about the complete list of options on our Medicare Supplement plans page.
Most Popular Medicare Supplement Insurance Plans in Hawaii
For Hawaii residents eligible for Medicare after 2020, two options stand out as the top choices for comprehensive coverage:
Plan G: This is the most comprehensive coverage available to new enrollees. Once you pay your annual Part B deductible, Plan G covers 100 percent of your remaining Medicare-approved out-of-pocket costs.
Plan N: This plan offers lower monthly premiums. In exchange, you pay small copayments (up to $20 for some doctor visits and up to $50 for ER visits) and pay excess charges if a provider doesn't accept Medicare assignment.
Feature | Plan G | Plan N |
Part A Hospital Deductible | Covered (100%) | Covered (100%) |
Part B Coinsurance | Covered (100%) | Covered (Except small copays) |
Doctor Visit Copays | $0 | Up to $20 |
Emergency Room Copays | $0 | Up to $50 |
Part B Excess Charges | Covered | Not Covered |
Which Hawaii senior are you?
Choosing the right plan depends heavily on your personal health needs and budget preferences:
The Planning Senior: You prefer a higher, predictable monthly premium so you don't have to worry about unexpected medical bills. Once your Part B deductible is met, your coverage pays nearly everything. Right fit: Plan G
The Budget-Conscious Senior: You are generally healthy, don't visit the doctor often, and want to keep your monthly costs low. You're comfortable paying a small copay when you see a doctor. Right fit: Plan N
The Grandfathered Veteran: You became eligible for Medicare before January 1, 2020, and want first-dollar coverage where the insurance company pays every gap, including the Part B deductible. Right fit: Plan F
Hawaii Medicare Enrollment Periods and Switching Rules
Timing is critical when buying a Medigap policy:
Initial Open Enrollment Window: Your six-month Medigap Open Enrollment Period starts the very first month you're age 65 or older and enrolled in Medicare Part B.
Guaranteed Issue Protections: During this initial six-month window, insurance carriers can't deny your application, use medical underwriting, or charge you higher rates because of pre-existing conditions.
Standard Switching Rules: Hawaii follows standard federal guidelines and doesn't offer an annual Medigap Birthday Rule. If you want to switch policies after your initial open enrollment period ends, you'll generally have to answer health questions and pass medical underwriting unless you qualify for a special enrollment period.

Medicare Supplement Carriers in Hawaii
Hawaii features a mix of local and national insurance companies authorized to sell Medigap policies, including:
HMSA (Hawaii Medical Service Association - Blue Cross Blue Shield of Hawaii)
UnitedHealthcare (AARP)
Mutual of Omaha
State Farm
Because medical benefits are standardized by law, you should evaluate carriers based on three key factors:
Customer service reputation and familiarity with local providers.
Premium rating methods (attained age, issue age, or community rating), which affect how rates rise as you grow older.
Historical rate increase stability.
At SelectQuote, we independently compare historical rate data across recognized carriers to help protect you from sudden price increases down the road.
Medigap Rates in Hawaii by ZIP Code
Most insurance carriers in Hawaii set rates based on age, gender, and tobacco use. Your base premium will also vary depending on your specific island and county:
Honolulu County (Oahu): Oahu has the state's largest medical facilities, such as Queen's Medical Center. Because of its higher population density, Oahu often sees competitive rates and plenty of carrier choices.
Hawaii County (The Big Island) and Maui County: Regional rates may adjust slightly based on local network access and the need for inter-island travel for specialized care.
Kauai County: Neighbor islands with smaller provider networks may experience unique pricing structures.
Because the cost of living in Hawaii is high, comparing local ZIP code quotes is the best way to make sure you aren't overpaying for your plan.
Frequently Asked Questions
Can I be denied a Medicare Supplement plan in Hawaii due to my health?
If you apply during your six-month Medigap Open Enrollment Period, carriers can't deny you or charge extra for pre-existing conditions. If you apply outside this window, you must go through medical underwriting, and insurers can deny coverage or charge higher premiums based on your health history.
Can I travel to the mainland or between islands with my Hawaii Medigap plan?
Yes. Because Medigap acts as a secondary payer to Original Medicare, you can use your coverage at any hospital or doctor's office in the United States that accepts Medicare. This flexibility is a major benefit for Hawaii residents who travel to Honolulu or the mainland U.S. for specialist treatments.
Do Hawaii Medicare Supplement plans cover prescription drugs?
No. Medigap policies sold today don't include prescription drug benefits. To cover your medications, you'll need to purchase a separate standalone Medicare Part D plan.
