Quick take
- Children's Mercy Hospital Kansas is the lowest-cost option at $1,214 - $2,031 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 $3,245, and it's often lower than what insurance pays before your deductible is satisfied.
- Ask whether this procedure can be done at a freestanding ambulatory surgical center - they're typically 30-60% cheaper than a hospital for identical care, and most aren't in this hospital-only dataset.
BJC HealthCare, SSM Health, Mercy Health, and CoxHealth divide Missouri roughly by region, with meaningful inter-system competition in both St. Louis and Kansas City. Barnes-Jewish Hospital (BJC) is the dominant academic medical center. Rural Missouri - particularly the Ozarks - has significant critical access hospital coverage where pricing structures differ from PPS hospitals. 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 (2) report prices above $28,303, including University Health Truman Medical Center at $46,787, 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 $3,245 versus $76 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 | ~$3,245 |
| Deductible met - 20% coinsurance | ~$649 |
| Out-of-network provider | $7,139+ |
