What affects the price of knee replacement?
Surgery that replaces a worn-out knee joint with an artificial implant to relieve pain and restore movement.
- How you pay: cash (self-pay) prices are often lower than insurer-negotiated rates, and the hospital's gross "list price" is rarely what anyone actually pays.
- Your insurance plan: each insurer negotiates its own rate with each hospital, so the same procedure can vary by thousands of dollars across plans.
- Where it's done: hospital outpatient departments usually charge more than independent imaging centers or ambulatory surgery centers.
- Extra services: anesthesia, pathology, facility fees, and physician fees may be billed separately from the listed procedure price.
- Complexity: complications or additional findings during the procedure can change the final bill.
Prices shown are from hospital-published price transparency data. Your actual cost may vary based on your specific insurance plan, treatment complexity, and other factors. This page is not medical or billing advice.
