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.

Self-pay patients in Maryland often have access to significantly discounted rates for knee replacement surgery. Under federal price transparency rules (45 CFR § 180.50), hospitals must publish their discounted cash prices alongside standard charges.

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.
