Oahu’s “second city” has Honolulu County’s full plan menu, Queen’s West Oahu next door in Ewa Beach, and the Daniel K. Akaka VA Clinic that opened here in 2024.
What to know before you compare plans in Honolulu County
Kapolei, Makakilo and the Waianae Coast share Honolulu County’s full Medicare menu: Kaiser Permanente, HMSA and national-carrier Advantage plans, every Medigap company licensed in Hawaii and the full Part D lineup. Hospital care on this side runs to Queen’s West Oahu in Ewa Beach and Pali Momi in Aiea, both of which contract through HMSA and the national plans; Kaiser members are referred to Moanalua.
The Akaka VA Clinic brought primary care, specialty care and imaging to West Oahu veterans who used to drive to the Tripler campus. For veterans it does not change the Part B rule: VA care is not creditable for Part B, and the late penalty is permanent. We compare what is sold at your ZIP code with your doctors, your pharmacy and your benefits in front of us.

Your options
Which kind of plan fits you in Kapolei?
Medicare Advantage
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.
Medigap pairs with Original Medicare and lets you see any provider that accepts Medicare — Queen’s, Straub, Hilo Benioff, or a specialist on the mainland.
Honolulu County typically offers Medicare Advantage plans from Kaiser Permanente, HMSA and national carriers, every Medigap company licensed in Hawaii, and the full Part D lineup, set by county and changing each plan year.
Is Queen’s West Oahu in my plan’s network?
Queen’s West Oahu contracts with some Advantage plans and not others, and the list changes each year. With Original Medicare and a Medigap policy there is no network. We confirm before you enroll.
How much does your help cost?
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
