Medicaid
Medicaid is run by each state, and it pays fixed rates to the providers that accept it, so the price doesn't change from one hospital to the next. Most people on Medicaid owe nothing or a small copay for covered care, but what's covered and what you owe depends on your state and plan. CostKits doesn't show a Medicaid price here because those rates are set by the state, not negotiated by each hospital. The question that matters is whether the provider accepts your Medicaid plan, so ask before you schedule.

Quick take
- KAISER FOUNDATION HOSPITAL - WESTSIDE is the lowest-cost option at $10,206 - $409 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 $10,615, 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.
Oregon Health & Science University (OHSU) anchors the academic tier and the Portland market. Providence Health and Legacy Health compete for commercial volume in Portland, while PeaceHealth covers the southern coast and Eugene corridor. Oregon passed aggressive price transparency legislation, and its hospital-reported data is among the most complete in the West. 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.

Why prices vary - and what it means for your coverage
A small number of hospitals (3) report prices above $12,802, including PeaceHealth Southwest Medical Center at $15,890, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $10,615 versus $37,458 inpatient (about 3.5× more), 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.
On top of the facility price, your actual bill depends on your deductible, your out-of-pocket maximum, and whether every provider involved - not just the facility - is in-network.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$10,615 |
| Deductible met - 20% coinsurance | ~$2,123 |
| Out-of-network provider | $23,353+ |
