What the whole procedure costs
The rate above is the physician’s fee on its own. The facility bills separately, and for most procedures the facility is the larger half of the bill. These are 2026 national Medicare amounts.
Choosing a surgery center over a hospital saves about $3,724 on the Medicare allowed amount for total knee replacement. Ask whether your procedure can be done at an ambulatory surgery center.
Medicare pays the hospital a single comprehensive amount for this procedure, covering the facility's share of the encounter including implants and supplies. Medicare allowed amounts are not what an uninsured patient is charged, and not a quote. Private plans typically allow more.

What these numbers are
Every figure on this page is a 2026 Medicare allowed amount: the physician line comes from the Physician Fee Schedule adjusted by geographic practice-cost indices, and the facility totals come from the CMS hospital outpatient (OPPS) and ambulatory surgery center rates. None of them is a hospital chargemaster price, your insurer's contracted rate, or a quote. Anesthesia, pathology, imaging reads and follow-up care are billed under their own codes when they apply, and an inpatient stay is paid a different way again.

Total Knee Replacement and how Missouri is priced
Missouri is a three-locality state: metropolitan St. Louis and metropolitan Kansas City are each priced separately, and everywhere else falls into a rest-of-state locality with lower geographic adjustments. Both metro localities approve higher amounts than outstate Missouri, and the Kansas City locality applies only to the Missouri side of that metro, since the Kansas side prices under Kansas's statewide locality. Springfield, Columbia, and the rural counties all share rest-of-state factors. The metro-versus-outstate gap is the main pricing story here.
St. Louis and Kansas City hold the state's academic medical centers and most of its specialty depth, drawing patients from far beyond Missouri's borders, including southern Illinois and eastern Kansas. Outstate Missouri is served by regional hubs in Springfield, Columbia, and Cape Girardeau, with the Ozarks and Bootheel among the harder places to reach specialty care. Rural hospital viability has been a persistent concern across the state.
This procedure: Total knee replacement resurfaces the ends of the thigh and shin bones and usually the kneecap with metal and plastic components after arthritis has worn away the cartilage. It is among the most common elective surgeries in the United States. The operation lasts one to two hours under spinal or general anesthesia, and recovery is more demanding than hip replacement: expect several months of dedicated physical therapy to regain bending and strength.

What Affects the Cost
- –Physical therapy is a bigger cost driver here than for almost any other surgery, because knee recovery typically requires more visits over more months.
- –Facility choice, hospital inpatient versus outpatient surgery center, can swing the total by a large margin.
- –The implant system and any patient-specific or robotic-assisted instrumentation add to the facility charge.
- –Nerve blocks for post-operative pain control are billed by anesthesia as separate procedures.
- –A stay in a skilled nursing or inpatient rehab facility, if you cannot go straight home, adds a substantial per-day cost.
- –Manipulation under anesthesia, needed by a minority of patients whose knee stiffens, is an additional procedure with its own charges.
Questions to Ask Before Booking
- 1.How many physical therapy visits will I realistically need, and how many does my plan cover per year?
- 2.Can my surgery be done outpatient, and what is the price difference at each facility you operate in?
- 3.Is prior authorization fully approved, including the conservative treatment documentation?
- 4.Will I get a nerve block, and is the anesthesia group in my network?
- 5.If I need a rehab facility stay instead of going home, what would that cost under my plan?
