Surgical costs for total knee arthroplasty in Massachusetts 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.

Total knee arthroplasty in Massachusetts can be performed in different settings depending on clinical complexity: hospital inpatient, hospital outpatient, or ambulatory surgery center (ASC).

ASCs typically offer lower prices because they have lower overhead and specialize in efficient, high-volume outpatient procedures. For eligible patients, ASCs can save 30–60% compared to hospital outpatient departments.

Not all patients are candidates for outpatient surgery. Your surgeon will determine the appropriate setting based on your health history, the procedure's complexity, and anticipated recovery needs.

Uninsured and self-pay patients can frequently access total knee arthroplasty at a lower cost than insured rates. Many hospitals in Massachusetts offer cash discounts of 30–70% off the standard chargemaster rate.

In Massachusetts, the average cash price for total knee arthroplasty is $6,844, which is 57% lower than the average list price of $16,105. This discount is typical of what self-pay patients can expect when asking for the hospital's uninsured rate.

Insured patients should check their plan's Summary of Benefits and contact their insurer for a pre-authorization cost estimate. Your out-of-pocket cost depends on your deductible, copay or coinsurance, and whether the provider is in-network. Even with insurance, comparing hospitals can help you choose a provider where your plan negotiates the best rates.
