What this number is
The figures on this page are 2026 Medicare physician allowed amounts for a specific CPT code: the professional fee, adjusted by geographic practice-cost indices. They are not a hospital chargemaster price, not your insurer's contracted rate, and not a quote. Hospital facility fees, anesthesia, implants, imaging reads, and pathology are billed separately when they apply.

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?
