Worth knowing: A small number of hospitals report very high prices above $7,644, which pulls the overall range wider than what most patients encounter. The typical range above is a better guide for planning.
Every hospital in this dataset offers a cash price — with a median of $2,458. If your deductible hasn't been met, always ask for the self-pay rate before scheduling.

What you'll actually pay — example scenarios

Your situation Estimated out-of-pocket
Deductible not yet met (pay in full) ~$2,236
Deductible met — 20% coinsurance ~$447
Out-of-network provider $4,919+

Based on the state median of $2,236. Your actual cost depends on your plan deductible, coinsurance rate, and network tier. Get YOUR personalized estimate →

What this means for you

If you haven't met your deductible, you are effectively a cash-pay patient.

That means:

  • You should shop prices directly — the same way you'd compare any major purchase
  • Insurance may not get you a better deal than the cash price
  • The cheapest facility can save you $2,160+ vs. the median.

This is the single biggest lever most patients have to reduce their cost.

Lower-cost options in Missouri start around $2,021 or below. Most hospitals cluster between $2,021 and $4,270. A smaller group reports prices above that — often academic medical centers or high-cost markets.

If you're comparing specific hospitals, the lowest self-pay rates reported in this dataset include: SOUTHEAST HEALTH CENTER OF STODDARD COUNTY LLC BLOOMFIELD CLINIC in North Bloomfield (cash price from $2,021); SOUTHEAST HEALTH CENTER OF STODDARD COUNTY LLC FAMILY MEDICINE OF POPLAR BLUFF in Poplar Bluff (cash price from $2,021); SOUTHEAST HEALTH CENTER OF STODDARD COUNTY LLC MALDEN CLINIC in Malden (cash price from $2,021).

Missouri 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 the most actionable price in this order:
  1. Cash price — the self-pay rate you can actually negotiate and pay
  2. Negotiated rate — if reported by the hospital across insurance contracts
  3. Gross charge — fallback only; this is the inflated list price few people pay

This reflects the real prices patients encounter — not inflated chargemaster rates.

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.
Important: Many procedures are done at ambulatory surgical centers (ASCs) that are often 30–60% cheaper than hospital outpatient departments with the same clinical quality. Most ASCs are not in this hospital dataset — meaning your cheapest option may not even appear here. Ask your doctor if the procedure can be done at a freestanding ASC.

Most expensive knee replacement providers in Missouri

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.

Why prices vary this much

A small number of hospitals (10) report very high prices above $7,644, which drives much of the overall price range. Excluding these, most facilities cluster in a significantly tighter band.

Among the cities with the most reporting hospitals, Dexter has a median reported price of $2,021 across 2 facilities, while facilities in Kansas City tend to report lower prices (median: $1,882). City-level variation within a state often reflects local market structure, not procedure complexity.

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.
