Best Medicare Plans in Hawaii 2026 — Complete Guide
What are the best Medicare plans in Hawaii in 2026? Hawaii has over 250,000 Medicare beneficiaries and a Medicare market that is unlike any other state in the United States. Hawaii’s geographic isolation — the most remote island chain in the world — creates unique challenges and opportunities for Medicare beneficiaries. Hawaii has some of the most competitive Medicare Advantage markets in the nation on Oahu while other islands face significant healthcare access limitations. Hawaii seniors also benefit from some of the longest life expectancies in the world — driven by the famous Hawaii Diet and active outdoor lifestyle. Finding the best Medicare plans in Hawaii in 2026 requires understanding Oahu’s competitive Medicare market, the very different situations on Maui, the Big Island, and Kauai, and the critical importance of mainland access for complex medical care. In this complete guide we break down the best Medicare plans in Hawaii in 2026 so Hawaii seniors can make the most informed Medicare decisions possible.

Why Hawaii Has Unique Medicare Considerations in 2026
Hawaii offers some of the most unique Medicare circumstances of any state in the United States in 2026 and Hawaii seniors need to understand the distinctive aspects of the Hawaii Medicare market.
Hawaii has over 250,000 Medicare beneficiaries concentrated primarily on Oahu — which has approximately 70% of Hawaii’s total population. Hawaii’s Medicare market is unique in several critically important ways that directly affect plan selection.
Hawaii has some of the highest healthcare costs in the entire United States — driven by the logistical challenges of operating healthcare facilities on remote islands thousands of miles from the continental supply chain. Everything from medical equipment to medications to healthcare workers costs more in Hawaii than on the mainland. This cost environment translates directly into higher Medicare Advantage premiums and higher Medigap premiums compared to mainland states.
Hawaii is home to major healthcare systems including Hawaii Pacific Health — which includes Straub Medical Center, Pali Momi Medical Center, Wilcox Medical Center on Kauai, and Kapiolani Medical Center — and The Queen’s Health Systems — which includes The Queen’s Medical Center — the largest hospital in Hawaii and the state’s primary Level I Trauma Center. Access to The Queen’s Medical Center and other major Oahu hospitals is a critical network consideration for Medicare Advantage plan selection in Hawaii.
The mainland access issue is the most critical and most unique aspect of Medicare planning in Hawaii. For complex medical conditions — advanced cancer, complex cardiac surgery, rare neurological conditions, major organ transplantation — Hawaii patients often travel to the continental United States for care. For these needs Original Medicare with Medigap Plan G provides seamless nationwide coverage at any Medicare-accepting provider on the mainland — a significant advantage over Medicare Advantage plans that may restrict out-of-network coverage.
Hawaii also has a significant military veteran and active duty population — particularly on Oahu — and many Medicare-eligible veterans have access to TRICARE For Life which coordinates with Medicare as a comprehensive secondary payer.
Hawaii’s SHIP program — the State Health Insurance Assistance Program of Hawaii — provides free Medicare counseling throughout the state including neighbor island outreach.
Hawaii’s HMSA — The Dominant Insurance Player
Before discussing specific plans it is essential to understand the dominant role of Hawaii Medical Service Association (HMSA) — Blue Cross Blue Shield of Hawaii — in the Hawaii healthcare market.
HMSA is the dominant health insurer in Hawaii with relationships with virtually every healthcare provider in the state. HMSA has the most comprehensive provider network in Hawaii — including providers on all major islands — making it the insurance company with the deepest Hawaii-specific healthcare relationships.
HMSA Medicare Advantage plans in Hawaii are consistently among the best Medicare plans in Hawaii due to their comprehensive provider networks that span all major islands and their deep integration with Hawaii’s healthcare community.

Best Medicare Supplement Plans in Hawaii 2026
For Hawaii seniors who prefer Original Medicare with a Medigap supplement Hawaii has important considerations — particularly regarding mainland access and higher-than-average premiums.
Best Medicare Supplement Plan in Hawaii — Plan G
Medigap Plan G is the best Medicare supplement plan for most Hawaii seniors in 2026 — and is particularly important for Hawaii seniors who may need mainland medical care.
After paying the $257 annual Part B deductible Plan G covers 100% of all Medicare-approved costs — including care at any Medicare-accepting provider on the mainland. This nationwide coverage is uniquely important in Hawaii where complex cases routinely require travel to major mainland academic medical centers.
Average Medigap Plan G costs in Hawaii in 2026:
- Age 65 — $180 to $320 per month
- Age 70 — $218 to $375 per month
- Age 75 — $260 to $435 per month
Hawaii Medigap Plan G premiums are among the highest in the United States — significantly above the national average due to Hawaii’s high healthcare cost environment. This higher premium is a real financial consideration for Hawaii seniors — but the value of nationwide coverage including mainland access may justify the premium for many beneficiaries.
Top providers of Medigap Plan G in Hawaii in 2026:
- AARP UnitedHealthcare — strong national presence in Hawaii
- HMSA Blue Cross Blue Shield Hawaii — dominant local brand
- Mutual of Omaha — competitive pricing in Hawaii
- Aetna — competitive in Hawaii markets
Medigap Plan N in Hawaii 2026
Medigap Plan N offers lower premiums than Plan G in Hawaii with up to $20 doctor visit copays.
Average Medigap Plan N costs in Hawaii in 2026:
- Age 65 — $138 to $255 per month
- Age 70 — $165 to $298 per month
Even Plan N premiums in Hawaii are above the mainland average — reflecting Hawaii’s high healthcare cost environment.
Mainland Access — The Most Critical Hawaii Medicare Consideration
The mainland access issue is the single most important and unique factor in Hawaii Medicare planning — and it must be addressed directly.
Why Mainland Access Matters for Hawaii Medicare Beneficiaries
Hawaii’s healthcare system — while excellent for primary care and most specialty care — has limitations for highly complex or rare conditions. Hawaii lacks:
- An NCI-designated comprehensive cancer center — complex cancer cases often travel to UCSF, Stanford, or MD Anderson
- Major academic medical centers for rare neurological conditions
- High-volume specialty surgical centers for complex procedures
- Organ transplant centers for some organs
When Hawaii Medicare beneficiaries require this type of specialized care they travel to the mainland — typically to healthcare centers in California, Texas, or other mainland states.
How Medicare Advantage Handles Mainland Care
Medicare Advantage plans cover emergency care anywhere nationwide but may restrict non-emergency out-of-network care to the plan’s service area — Hawaii. If you need planned complex care on the mainland under a Medicare Advantage HMO plan you may face significant out-of-network costs or the plan may not cover the mainland care at all.
Medicare Advantage PPO plans provide more flexibility for mainland access — with out-of-network coverage at higher cost-sharing. But even PPO out-of-network coinsurance can be substantial for major procedures.
How Original Medicare with Medigap Plan G Handles Mainland Care
Original Medicare with Medigap Plan G covers any Medicare-accepting provider anywhere in the United States — mainland or Hawaii — at $0 after the annual deductible. For Hawaii seniors who may need mainland care there is no coverage concern — Stanford, UCSF, MD Anderson, Mayo Clinic — all covered seamlessly.
This mainland access advantage of Original Medicare with Medigap Plan G is particularly important for:
- Hawaii seniors with cancer who may need NCI center care
- Hawaii seniors with rare or complex conditions
- Hawaii seniors with cardiac conditions requiring specialized surgery
- Hawaii seniors who spend significant time on the mainland (snowbirds in reverse)
Oahu vs Neighbor Islands Medicare 2026
Hawaii’s Medicare market differs dramatically between Oahu and the neighbor islands.
Oahu Medicare 2026
Oahu — including Honolulu, Kailua, and the communities of the most densely populated island — has the most competitive Medicare market in Hawaii. Oahu is anchored by The Queen’s Medical Center, Hawaii Pacific Health facilities, and Kaiser Permanente Hawaii — creating a competitive environment for Medicare Advantage plans.
HMSA, UnitedHealthcare, Kaiser Permanente, Humana, and Aetna all offer Medicare Advantage plans on Oahu. The competitive market creates good $0 premium plan options with comprehensive benefits for Oahu seniors.
Maui Medicare 2026
Maui and Maui County — including the islands of Maui, Molokai, and Lanai — have more limited Medicare Advantage options. The primary hospital is Maui Health System (previously Maui Memorial Medical Center). HMSA is the strongest Medicare Advantage option on Maui due to its island-wide network.
For Maui seniors who may need specialized care not available on Maui — including many cardiac procedures and cancer care — Original Medicare with Medigap Plan G provides seamless access to Oahu specialists and mainland care without network concerns.
Big Island (Hawaii County) Medicare 2026
The Big Island — Hawaii County — has limited Medicare Advantage options. Hilo Medical Center and North Hawaii Community Hospital are the primary facilities. HMSA has the strongest network on the Big Island.
For many Big Island seniors who routinely travel to Oahu for specialty care Original Medicare with Medigap Plan G is the recommended choice — providing coverage for both Big Island care and Oahu specialist visits without network restrictions.
Kauai Medicare 2026
Kauai — the Garden Isle — has very limited Medicare Advantage options. Wilcox Medical Center (part of Hawaii Pacific Health) is the primary facility. HMSA’s connection to Wilcox through Hawaii Pacific Health makes HMSA the primary Medicare Advantage option on Kauai.
Many Kauai seniors travel to Oahu for specialist care — Original Medicare with Medigap Plan G provides seamless coverage for both Kauai and Oahu care.
