Knee Replacement Cost in Hawaii (2026): Average Prices & What You'll Pay
What does a knee replacement cost in Hawaii?
For a commercially insured patient, a knee replacement in Hawaii typically runs $4,554–$14,166 once facility and physician fees are combined. The median reported facility price across 7 hospitals is $4,243. The figures draw on CMS fee schedules and hospital price transparency data published under federal law.
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. Knee replacement is a high-cost elective procedure where facility selection has an outsized impact on total cost. Hospital outpatient and ambulatory surgery center rates for knee replacement have converged on outcomes but diverged further on price - ASC rates are typically 30–50% below hospital rates for the same implant and surgeon. Medicare Advantage plans increasingly direct patients to designated bundled-payment facilities where your out-of-pocket liability is capped.

Quick take
- Hawaii Pacific Health is the lowest-cost option at $2,065 - $2,178 below the state median, just by choosing where you go.
- Ask for the cash price if your deductible isn't met - the median cash price here is $5,978, and it's often lower than what insurance pays before your deductible is satisfied.
- This dataset covers hospitals only - freestanding ASCs, which routinely run 30-60% cheaper for the same procedure, aren't included, so it's worth asking your doctor whether one is an option.

Hawaii Knee Replacement prices by facility
All prices below come from hospital chargemasters - the official price lists each hospital must publish under federal law. Gross charge is the undiscounted list price; cash price is the self-pay rate; negotiated range covers the spread across insurance contracts.
How we calculate "Your Price"
We prioritize cash price (the self-pay rate) over the negotiated rate, and only fall back to the gross charge, the inflated list price few people actually pay, when nothing else is reported.

|---|---|---|---|---|---|
| #1 | Hawaii Pacific Health | HI | $2,065 | -$2,178 | $1,073–$17,879 |

Why prices vary - and what it means for your coverage
Setting matters too: the median outpatient price is $5,978 versus $2,065 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.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$8,275 |
| Deductible met - 20% coinsurance | ~$1,655 |
| Out-of-network provider | $18,205+ |
Frequently asked questions: knee replacement costs in Hawaii
How much does a knee replacement cost in Hawaii?
Across 7 Hawaii hospitals that publish prices, a knee replacement ranges from $609 to $47,452, with a median of $4,243. Most facilities fall between $2,065 and $7,714. What you pay depends on the facility, your insurance, and whether you have met your deductible.
Where is the cheapest place to get a knee replacement in Hawaii?
Based on declared prices, the lowest-cost facility in our Hawaii data is Hawaii Pacific Health at about $2,065. Freestanding ambulatory surgery and imaging centers are often cheaper still and may not appear in hospital price data - ask your doctor whether one is an option.
Why is a knee replacement so much cheaper at some Hawaii hospitals?
Prices vary up to 77.9× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Hawaii, the median cash (self-pay) price is $5,978 versus a median negotiated rate of $268 - about 22.3× higher. Asking for the cash price or 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 knee replacement 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.

What matters before you schedule
ASC vs. hospital
Hospital outpatient departments typically charge 2-4x more than ASCs or independent centers for the same knee replacement - same outcome, very different bill. Call ahead and ask for a self-pay or cash quote at each setting you're considering.
What's on your bill
A knee replacement involves multiple providers who bill separately - typically ASC Facility Fee, Orthopedic Surgeon Professional Fee, Anesthesia. Check each line item against your Explanation of Benefits to catch billing errors.
Cost by type
Which type your doctor orders for this knee replacement changes the billing code, and what you pay. For example: A recognized variation that can change the billing code and what you owe.
What to ask before you book
Get the CPT code from your doctor, confirm every provider involved (not just the facility) is in-network, ask for the cash-pay rate if you're uninsured or haven't met your deductible, and request a written estimate for knee replacement before you schedule.
CostKits compiles hospital price transparency data to help families make informed decisions. Track and manage your healthcare costs (free account).
