How much does a hip or knee replacement cost? The short answer
In the United States, hospital-based hip or knee replacement carries a list price that averages around $40,000 and can reach $100,000 depending on facility, implant, and length of stay. In Hawai‘i specifically, total knee replacement averages around $40,740 versus a national average near $32,570 — paradise carries a premium (see the Honolulu-specific breakdown).
But list price is not your price. What you pay depends entirely on the path: insured, Medicare, or self-pay — and Dr. Paul Morton's office in Honolulu verifies your benefits and gives you a written estimate before anything is scheduled.
- List price is the sticker, not your bill — insurers, Medicare, and self-pay packages all set numbers below it
- With insurance, your exposure is deductible plus co-insurance up to your out-of-pocket maximum
- Whether you stay overnight is the biggest lever: same-day outpatient surgery costs less than an inpatient hospital stay for the same operation
- Self-pay packages bundle surgeon, facility, anesthesia, implant, and a year of follow-ups into one written price
- Robotic assistance doesn't change coverage or add a patient fee at this practice
The numbers at a glance
| Line item | Typical figure | Notes |
|---|---|---|
| Total knee — Hawai‘i hospital list price | ~$40,740 | Above the ~$32,570 national average |
| Hip or knee — US hospital list price | ~$40,000 average, up to $100,000 | Facility, implant, and length of stay drive the spread |
| Surgeon's fee | $3,000–$15,000 | Covers the operation and the global follow-up period |
| Anesthesia | $1,000–$2,500 | — |
| Implant | $4,000–$7,000 | Depends on design and materials |
| Facility fee | The biggest variable | Hospital operating rooms and inpatient beds dwarf surgery-center costs |
| Physical therapy | $50–$350 per session | Over several weeks to months |
| Outpatient surgery center (Medicare) | About 30% less than hospital | Same surgery in a leaner setting |
| Bundled self-pay package | Roughly half of hospital pricing | Surgeon, facility, anesthesia, implant, and a year of follow-ups |
About these figures: the market numbers above are published hospital list-price averages and typical ranges, not this practice's prices. They change every year and vary by facility, implant, and length of stay, so treat them as orientation. Medicare's public Procedure Price Lookup tool (medicare.gov) shows the surgery-center versus hospital-outpatient difference for a specific procedure; your own number comes from a written estimate after benefits verification.
Where the money goes
A joint replacement bill has five main components:
- Surgeon's fee: roughly $3,000–$15,000 — covering the operation and global follow-up period
- Anesthesia: roughly $1,000–$2,500
- Implant: roughly $4,000–$7,000 depending on design and materials
- Facility fee: the biggest variable — hospital operating rooms and inpatient beds dwarf outpatient surgery-center costs
- Physical therapy: $50–$350 per session over several weeks to months
What you actually pay with insurance
With commercial insurance, your exposure is your deductible plus co-insurance up to your plan's out-of-pocket maximum — for many patients, a few thousand dollars for the entire episode, sometimes less late in a plan year when deductibles are already met. Medicare covers joint replacement as a standard benefit; supplemental plans often shrink the remainder to very little (Medicare specifics here). The practice verifies your benefits and gives you an estimate before surgery — surprises are a billing failure, not a fact of life.

Insured vs. Medicare vs. self-pay: who pays what
Three paths, three very different bills for the identical operation. Which one fits you?
- Commercial insurance (HMSA, UHA, HMAA, United, Aetna, Cigna and others): you pay your deductible and co-insurance up to the plan's out-of-pocket maximum; the office handles prior authorization and verifies benefits first — see plans accepted
- Original Medicare: outpatient joint replacement falls under Part B — after the deductible, Medicare pays 80% of its approved amount and you owe 20%; a Medigap supplement often shrinks that to very little
- Medicare Advantage: copays per procedure or stay, a network, often prior authorization, and an annual out-of-pocket maximum; HMO-style plans usually need a PCP referral
- VA Community Care and TRICARE: a referral or authorization from your VA provider or plan, coordinated by the office — see VA knee replacement
- Self-pay, high-deductible, or international: one written all-inclusive package price; the office will run the package against your insurance route so you can compare
The outpatient lever: same surgery, smaller bill
The single biggest cost lever is whether you stay overnight. Same-day outpatient surgery runs leaner than an inpatient hospital stay — no hospital bed, no overnight nursing, a shorter facility stay — and for self-pay patients the difference is dramatic: Dr. Morton's bundled packages (surgeon + facility + anesthesia + implant + a year of follow-ups) run roughly half of hospital list pricing. Modern rapid-recovery protocols are what make same-day discharge safe for qualified patients — the savings are a byproduct of better surgery, not a discount version of it.
Questions worth asking any surgeon about cost
Wherever you have surgery, ask these:
- Can I get a written estimate of my total out-of-pocket cost?
- Is same-day outpatient surgery an option for my case?
- Is there a bundled self-pay price, and what exactly does it include?
- How many PT sessions should I budget for?
- What costs could arise that aren't in this estimate?
The cost of waiting
One number rarely makes the spreadsheet: what delay costs. Years of injections, braces, imaging, and lost activity add up — and joints don't get cheaper to fix as they deteriorate; the quad weakens and deformity progresses, which makes eventual surgery and recovery harder. If pain is already limiting your life despite conservative care, a consultation prices out your actual options — a robotic hip replacement or knee replacement, a partial knee, or another year on the non-surgical ladder — with real numbers instead of internet averages.
How to get a real estimate
What the office needs to produce a real estimate: your insurance card and plan type (or a note that you're self-pay), any prior X-rays or MRI, and your therapy and injection history. The team verifies benefits, confirms whether same-day outpatient surgery is an option for your case, and gives you a written estimate before anything is scheduled. Call (808) 439-6201 or book online — clinics in Honolulu (Ala Moana), West O‘ahu (Kunia), Hilo and Kona, and most new patients are seen within one to two weeks. Managed-care and Medicaid/Quest plans need a referral from your primary care physician, which the office helps arrange; neighbor island patients can start by telehealth when an in-person visit isn't practical.
- Step 1
Verify benefits
Insurance card and plan type in hand, the office checks coverage, referral rules, and prior authorization.
- Step 2
Exam + standing X-rays
Candidacy for surgery — and for same-day discharge — is settled in one visit.
- Step 3
Written estimate
Your expected out-of-pocket cost, or a self-pay package price, in writing before anything is scheduled.
- Step 4
Surgery where it serves you best
Robotic replacement at The Queen's Medical Center, Adventist Health Castle, or Hilo Community Surgery Center — same-day when you qualify, an overnight stay when your health calls for it.
