Knee Replacement Cost in South Dakota (2026): Average Prices & What You'll Pay

What does a knee replacement cost in South Dakota?

Expect roughly $4,936 to $15,532 for a knee replacement in South Dakota if you're commercially insured — that range already folds in both the facility charge and the physician fee. The median reported facility price across 11 hospitals is $3,915. It's built from CMS fee schedules and federally mandated hospital price transparency data.

Sanford Health and Monument Health are the dominant systems. The Sanford Health network extends across both Dakotas and into Minnesota and Iowa, giving it extraordinary commercial contracting leverage. South Dakota's rural geography — and the Sanford network's reach — means most residents have very limited facility alternatives.

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.

Across 11 South Dakota hospitals that publish prices, a knee replacement runs from as little as $522 (Douglas County Memorial Hospital) to $88,824 (Prairie Lakes Health Care System Inc.) — a 170.2× spread for the same procedure. A typical South Dakota facility lands around $3,915 — most sit in the $2,342–$9,080 band. Self-pay patients are quoted more than insurers actually pay: the median cash price is $5,493 versus a median negotiated rate of $1,704 — about 3.2× higher, so asking for the cash or insurer-negotiated rate is often the single biggest lever on your bill. Where you go inside South Dakota counts as much as which plan you have: Winner's median ($15,721) runs 7.1× Dakota Dunes's ($2,206).

Most expensive knee replacement providers in South Dakota

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 (2) report very high prices above $19,387, which drives much of the overall price range. Excluding these, most facilities cluster in a significantly tighter band.

Setting drives much of the gap in South Dakota: the median outpatient price is $3,720 versus $4,796 inpatient — about 1.3× more, so where a procedure is performed often matters more than which hospital you choose. Of the South Dakota facilities reporting prices, 5 fall in a low-cost tier (up to $2,342) while 6 sit in a high-cost tier ($9,160 and up) — a lower-priced option almost always exists within the same state.

Among the cities with the most reporting hospitals, Winner has a median reported price of $15,721 across 3 facilities, while facilities in Dakota Dunes tend to report lower prices (median: $2,206). 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.

Freestanding ambulatory surgery and imaging centers are often cheaper still and may not appear in hospital price data — ask your doctor whether one is an option.

Why is a knee replacement so much cheaper at some South Dakota hospitals?

Prices vary up to 170.2× because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In South Dakota, the median cash (self-pay) price is $5,493 versus a median negotiated rate of $1,704 — about 3.2× higher. 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 South Dakota?

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.
