Hawaii's island geography creates isolated health economies - each island is effectively its own market, and most specialized care on neighbor islands requires inter-island travel. Kaiser Permanente Hawaii and Hawaii Pacific Health cover most of the Oahu market. Transport and logistics costs embedded in hospital operating expenses push prices well above the mainland average for comparable services.

Why prices vary - and what it means for your coverage

Setting matters too: the median outpatient price is $1,240 versus $798 inpatient, so where a procedure happens often matters more than which hospital you pick. Setting drives most of the spread here: an ambulatory surgical center (ASC) is usually meaningfully cheaper than a hospital operating room for the same procedure, when your case qualifies.

None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.

Why is a sinus surgery so much cheaper at some Hawaii hospitals?

Typical prices vary about 2× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Hawaii, the median cash (self-pay) price is $1,240 versus a median negotiated rate of $348 - about 3.6× higher. Asking for the cash price as well as your insurer's negotiated rate is often the single biggest lever on what you pay.

How much will I actually pay out of pocket for a sinus surgery in Hawaii?

Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.
