Medicare in the region
West Hawaii is the sunny side of the Big Island, and a lot of its Medicare population arrived from somewhere else: mainland retirees in Waikoloa and Kailua-Kona, ranch families in Waimea, coffee farmers on the Kona slopes. The care map is two hospitals, Kona Community in Kealakekua and Queen’s North Hawaii in Waimea, plus Kohala Hospital in Kapaau, Kaiser’s Kona office and the Kailua-Kona VA clinic. Hilo is two hours across the saddle; Oahu is a 45-minute flight.
Newcomers bring mainland plans with them, and that is where trouble starts: an Advantage HMO from California or Washington generally covers only emergencies here. Moving your legal residence to Hawaii County opens a Special Enrollment Period and means choosing from what is sold here. We help retirees make that move cleanly, including the Medigap rules that differ by state.
Local plans to know: Kaiser Permanente Senior Advantage covers most of Hawaii County and Kaiser’s Kona Medical Office is its West Hawaii hub; HMSA’s neighbor island Akamai Advantage plans cover the whole island with interisland travel help for approved treatment. Kona Community Hospital is the public acute-care hospital; Queen’s North Hawaii in Waimea is a 35-bed rural hospital in the Queen’s system.
Counties: Hawaii (West Hawaii: Kailua-Kona, Holualoa, Kealakekua, Captain Cook, Ocean View, Waikoloa, Waimea (Kamuela), Hawi, Kapaau).
Each contracts differently with each plan; we check your doctors first.
Turning 65? Your Initial Enrollment Period is the 7 months around your birthday. Already on Medicare? The Annual Election Period is Oct 15–Dec 7, and Medicare Advantage Open Enrollment runs Jan 1–Mar 31. Moving to another island or losing a plan opens a Special Enrollment Period.
Your options
All-in-one Part C plans, often $0 premium, that use a local network — in Hawaii that usually means choosing between Kaiser, HMSA and a few national carriers, island by island.
How Advantage worksMedigap pairs with Original Medicare and lets you see any provider that accepts Medicare — Queen’s, Straub, Hilo Benioff, or a specialist on the mainland.
How Medigap worksStandalone drug coverage chosen around your medications and pharmacy. 2026 out-of-pocket cap: $2,100.
How Part D worksAdvantage plans built for a chronic condition, for nursing-facility care, or for people with both Medicare and Med-QUEST.
About SNPsQuestions from West Hawaii
Hawaii County typically offers Medicare Advantage plans from Kaiser Permanente (most of the county), HMSA’s neighbor island plans and some national carriers, every Medigap company licensed in Hawaii, and the full Part D lineup. We compare what is sold at your address.
A Medigap policy with Original Medicare works anywhere in the U.S. Most Medicare Advantage HMOs cover only emergencies outside their service area. Changing your legal residence to Hawaii opens a Special Enrollment Period to choose a plan sold here; see our Neighbor Islands guide and our sister sites for the state you left.
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
