Knee Replacement Surgery Cost in South Dakota (2026)

If you're researching knee replacement surgery costs in South Dakota, you'll find significant price differences between providers — even those just miles apart.

Surgical costs for knee replacement surgery in South Dakota are influenced by operating room fees, anesthesia, surgeon fees, and any implants or specialized equipment. Academic medical centers and large health systems often charge more than community hospitals or ambulatory surgery centers.

Based on data from 10 hospitals in South Dakota, knee replacement surgery prices range from $1,201 to $69,868 — a 58.2x difference. This wide variation underscores why comparing prices before scheduling is critical for controlling your out-of-pocket costs.

The setting where knee replacement surgery is performed in South Dakota significantly impacts total cost. Hospital inpatient stays are the most expensive, followed by hospital outpatient departments, then ambulatory surgery centers.

For patients who are medically appropriate for outpatient surgery, ASCs offer a compelling combination of lower cost and shorter wait times. Many are physician-owned and focus exclusively on surgical care.

Discuss options with your surgeon and, if you're self-pay, ask about pricing at each available setting before scheduling.

If you're paying out of pocket for knee replacement surgery in South Dakota, you may be able to negotiate a rate lower than the hospital's published list price. Federal law requires hospitals to post cash-pay rates, making it easier to compare options before scheduling.

In South Dakota, the average cash price for knee replacement surgery is $13,170, which is 54% lower than the average list price of $28,419. This discount is typical of what self-pay patients can expect when asking for the hospital's uninsured rate.

For insured patients, the negotiated rate between your plan and the hospital determines your cost share. If you haven't met your deductible, you may pay more than the cash price. It's worth asking the hospital whether their self-pay rate is lower than what your insurance would charge — some patients save money by not filing a claim.
