Best Health Insurance in Hawaii (2026)

Kaiser Permanente offers the best health insurance in Hawaii for HMO plans, while HMSA is the top choice for PPO coverage. Hawaii's marketplace has only these two carriers, so the HMO vs. PPO choice especially important.

Kaiser Permanente has the lowest HMO rates across all metal tiers and age groups analyzed. HMSA is the marketplace's only PPO provider. For a 40-year-old, its Silver plan costs $695 monthly, compared with $545 from Kaiser. Consider whether your doctors are in Kaiser's network and whether you need out-of-network or off-island care. If so, HMSA's PPO may be the better fit.

In our analysis of every 2026 Hawaii marketplace plan, the decision comes down to one question: HMO or PPO. The cost gap between those two network types widens with age, from $108 at 18 to $318 at 60 , which is more than double the $150 gap a 40-year-old pays for the same Silver-tier plan, regardless of carrier. The health insurance prices vary by age and network type. Silver-tier plan comparisons show clear category leaders:

By Age:

• Teens (18): Kaiser Permanente HMO ($389 monthly), HMSA PPO ($497)
• Young adults (26): Kaiser Permanente HMO ($437 monthly), HMSA PPO ($557)
• Adults (40): Kaiser Permanente HMO ($545 monthly), HMSA PPO ($695)
• Seniors (60): Kaiser Permanente HMO ($1,158 monthly), HMSA PPO ($1,476)

By Network Type (40-year-olds):

• HMO: Kaiser Permanente offers Silver coverage at $545 monthly
• PPO: HMSA provides Silver-tier plans at $695 monthly

At Silver, the $150 monthly gap between HMO and PPO plans produces no difference in deductibles or out-of-pocket maximums. Both carriers set those figures at $3,100 and $5,656 at this tier. The premium difference pays for network access only. For enrollees whose doctors are in Kaiser's network, the HMO plan costs $1,800 less per year with no coverage trade-off at Silver.

Kaiser Permanente's Silver-tier HMO costs $545 a month. HMSA's Silver-tier PPO costs $695 a month. The $150 difference is the core trade-off between network flexibility and premium cost at this tier.

We reviewed every 2026 plan in Hawaii's marketplace across five age groups and six metal tiers. With only two carriers in the state, the choice is narrower than in most states. The HMO vs. PPO decision and the deductible-versus-premium trade-off within each carrier are the two decisions that most affect your annual premium and out-of-pocket maximums.

Hawaii health insurance costs vary by plan type, metal tier and age. HMO plans are cheaper at most tiers. Kaiser Permanente's Silver-tier HMO is $150 less per month than HMSA's PPO equivalent for a 40-year-old. The relationship that surprised us most in our analysis is the Gold tier: HMSA's PPO Gold is $640 monthly versus Kaiser Permanente's HMO Gold at $571, a $69 gap that still favors the HMO, but it's 54% narrower than the $150 Silver gap. At Platinum, the HMO is $694 monthly and the PPO is $726.

*Average monthly premiums for 40-year-olds in Hawaii by plan type. Rates vary by age and location.

Hawaii's marketplace offers two carriers and one structural choice: Kaiser Permanente's HMO or HMSA's PPO. At Silver, that choice costs $150 monthly, with identical deductibles and out-of-pocket maximums on both sides. At Gold, the premium gap narrows to $69 and still favors the HMO. A 40-year-old whose doctors are in the Kaiser network pays $1,800 less per year at Silver with no deductible or cost-sharing difference.

If neither question applies, the $150 monthly savings with Kaiser Permanente at Silver is the default recommendation for most Hawaii enrollees.
