Quick take
- St Luke's Methodist Hospital is the lowest-cost option at $2,026 - $576 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 $2,731, 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.

Iowa's hospital market is dominated by UnityPoint Health and MercyOne (CommonSpirit), with relatively limited inter-system competition in most markets. Des Moines prices run below national averages, but facility fees at affiliated hospital systems can add substantially to the base service rates. University of Iowa Hospitals & Clinics is the primary academic referral center. 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 (7) report prices above $7,940, including MercyOne Genesis Davenport West Medical Center at $12,316, 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 $2,475 versus $2,026 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.
What you pay out of pocket on top of this depends on your deductible, your plan's out-of-pocket maximum, and whether every provider involved is in-network - not just the facility.
| Your situation | Estimated out-of-pocket |
|---|---|
| Deductible not yet met | ~$6,634 |
| Deductible met - 20% coinsurance | ~$1,327 |
| Out-of-network provider | $14,595+ |

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 knee replacement in Iowa?
Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.

What matters before you schedule
ASC vs. hospital
Hospital outpatient departments typically charge 2-4x more than ASCs or independent centers for the same knee replacement - same outcome, very different bill. Call ahead and ask for a self-pay or cash quote at each setting you're considering.
What's on your bill
A knee replacement involves multiple providers who bill separately - typically ASC Facility Fee, Orthopedic Surgeon Professional Fee, Anesthesia. Check each line item against your Explanation of Benefits to catch billing errors.
Cost by type
Which type your doctor orders for this knee replacement changes the billing code, and what you pay. For example: A recognized variation that can change the billing code and what you owe.
What to ask before you book
Get the CPT code from your doctor, confirm every provider involved (not just the facility) is in-network, ask for the cash-pay rate if you're uninsured or haven't met your deductible, and request a written estimate for knee replacement before you schedule.
