Cataract Surgery Cost in Hawaii (2026): Average Prices & What You'll Pay
What does a cataract surgery cost in Hawaii?
You could pay $560 or $574 for the same cataract surgery in Hawaii — depending entirely on which facility you choose. The median cash price across 2 reporting hospitals is $566. This data comes directly from hospital price transparency files published under federal law.
There's a gap between the sticker and the real price here: a median cash quote of $566 sits above the $361 insurers negotiate — about 1.6× higher, so asking for the cash or insurer-negotiated rate is often the single biggest lever on your bill. Across 2 Hawaii hospitals that publish prices, a cataract surgery runs from as little as $494 (Kahuku Medical Center in Kahuku) to $8,829 (Hawaii Pacific Health) — a 17.9× spread for the same procedure. Half of Hawaii facilities price it at or below $566, with most clustered between $558 and $574.

What you'll actually pay — example scenarios
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met (pay in full) | ~$566 |
| Deductible met — 20% coinsurance | ~$113 |

What this means for you
If you haven't met your deductible, you are effectively a cash-pay patient.
That means:
- You should verify your hospital is in-network before an elective visit when possible
- The cheapest facility can save you $17+ vs. the median.
This is the single biggest lever most patients have to reduce their cost.
Lower-cost options in Hawaii start around $558 or below. Most hospitals cluster between $558 and $575. A smaller group reports prices above that — often academic medical centers or high-cost markets.
How where you go changes what you pay for cataract surgery
The same cataract surgery bundles different services depending on the setting — facility fee, surgeon fee, and anesthesia each arrive as separate bills. Estimated ranges below reflect the typical full bundled cost, including all expected charges.
- Facility fee $549–$584
- Professional fee $803–$2,932
Estimated from CMS fee schedules + commercial rate multipliers
- Best value hospitals (lowest prices): Hawaii Pacific Health: $549; Kahuku Medical Center: $584
- Most expensive (outpatient): Kahuku Medical Center: ~$584; Hawaii Pacific Health: ~$549
→ Choosing the right facility can save $17+ vs. the state median.
Hawaii Cataract Surgery 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.
- Cash price — the self-pay rate you can actually negotiate and pay
- Negotiated rate — if reported by the hospital across insurance contracts
- Gross charge — fallback only; this is the inflated list price few people pay
This reflects the real prices patients encounter — not inflated chargemaster rates.
| # | Facility | City | Your Price | vs Median | Gross Charge |
|---|---|---|---|---|---|
| #1 | Hawaii Pacific Health | HI | $549 | -$17 | $915–$8,829 |
| #2 | Kahuku Medical Center | Kahuku, HI | $584 | +$18 | $494–$4,474 |

Where you can save the most on cataract surgery in Hawaii
These facilities have the lowest declared prices relative to the state median — they represent the best opportunities to reduce your out-of-pocket cost for this procedure.
| Facility | City | Your Price | vs Median |
|---|---|---|---|
| Hawaii Pacific Health | HI | $549 | -$17 |
| Kahuku Medical Center | Kahuku, HI | $584 | +$18 |
How to choose a lower-cost facility
- Choose independent outpatient centers when possible — freestanding ASCs (ambulatory surgical centers) consistently charge less than hospital outpatient departments for identical procedures.
- Ask for the cash price if your deductible isn't met — self-pay rates are often lower than what insurance pays before your deductible is satisfied, especially at facilities that have a high cash-price discount.
- Avoid hospital outpatient departments for routine cases — hospital-owned locations add a facility fee that freestanding centers don't charge, often adding $500–$1,500 to the same procedure.
Most expensive cataract surgery providers in Hawaii
These facilities report the highest prices for this procedure. Academic medical centers and specialty hospitals often top this list — their gross charges rarely reflect what anyone actually pays, but understanding the spread helps you negotiate.
| Facility | City | Price | vs Median |
|---|---|---|---|
| Kahuku Medical Center | Kahuku, HI | $584 | +$18 |
| Hawaii Pacific Health | HI | $549 | -$17 |
Why prices vary this much
Of the Hawaii facilities reporting prices, 1 fall in a low-cost tier (up to $558) while 1 sit in a high-cost tier ($575 and up) — a lower-priced option almost always exists within the same state.
The spread comes from how each hospital sets its chargemaster (the undiscounted list price), what cash discounts it applies, and what rates it negotiates with each insurer. Facility classification matters too — a hospital-owned outpatient center adds a facility fee that a freestanding clinic does not. Understanding these mechanics is the first step to paying less.

How insurance changes what you actually pay
Hospital list prices are only part of the picture. What you pay out of pocket depends on your deductible, your plan's out-of-pocket maximum, whether the facility is in-network, and whether your plan classifies the visit as outpatient or inpatient. A lower gross charge doesn't guarantee a lower bill if the facility is out-of-network or adds facility fees your plan doesn't cover.

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

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 cataract surgery in Hawaii?

Where You Get a Cataract Surgery Matters
Hospital outpatient departments typically charge 2–4× more than ASCs or independent centers for the same procedure — same outcome, very different bill.
Ambulatory Surgery Center
Ambulatory Surgery Center typically carries a mid-range price for a cataract surgery. Typically 40–60% less than hospital OP for surgical procedures. Anesthesia billed separately. You can shop here — call ahead and ask for a self-pay or cash quote.
Hospital Outpatient Department
Hospital Outpatient Department typically carries a higher price for a cataract surgery. Facility fee billed separately from professional fee. Provider-based billing adds facility overhead. You can shop here — call ahead and ask for a self-pay or cash quote.
What's Actually on Your Cataract Surgery Bill
A cataract surgery involves multiple providers — each bills separately. Understanding each line item helps you verify your Explanation of Benefits and catch billing errors.
Asc
- Facility Fee — ASC facility fee — usually lower than hospital outpatient.
- Surgeon Professional Fee
- Anesthesia — Often monitored anesthesia care (MAC) or topical; billed separately by the anesthesia provider.
- Intraocular Lens — Standard monofocal IOL covered. Premium IOL = separate non-covered upgrade.
Hospital Outpatient
- Facility Fee — Hospital outpatient facility fee — typically higher than an ASC.
- Surgeon Professional Fee
- Anesthesia
- Intraocular Lens
Cataract Surgery Cost by Type
Which type your doctor orders changes the billing code — and what you pay. Here's how the common types differ.
Standard Cataract Surgery
A recognized variation that can change the billing code and what you owe. CPT 66984 — phacoemulsification with monofocal IOL.
Complex Cataract Surgery
A recognized variation that can change the billing code and what you owe. CPT 66982 — complex cases (small pupil, dense cataract, prior trauma).
Premium-Lens Cataract Surgery
A recognized variation that can change the billing code and what you owe. Toric or multifocal IOL — the lens upgrade is a non-covered out-of-pocket charge.
This Procedure Is Shoppable — Choosing the Right Facility Can Save Thousands
Cataract Surgery is elective and schedulable. You have time to compare facilities — and hospital outpatient prices often run 2–4× higher than ASC, Hospital OP for identical clinical outcomes.
How to shop: Ask your doctor for the CPT code, then call 2–3 facilities and request an out-of-pocket cost estimate. Confirm your insurance is accepted. If uninsured, ask for the cash-pay rate — it's usually 20–50% below the list price.
Prior Authorization Is Usually Required
Most commercial and Medicare Advantage plans require pre-approval for cataract surgery before scheduling. If your doctor submits the order without prior authorization — or if the authorization lapses — your insurer can deny the entire claim, leaving you responsible for the full cost.
Action step: Call the member services number on your insurance card before scheduling. Ask: "Does this procedure require prior authorization?" Get the authorization number in writing and confirm it's attached to the claim before your appointment.
Who performs this: Cataract Surgery is typically performed by a Ophthalmology. The specialist's professional fee is billed separately from the facility charge — you will likely receive separate bills from each.
