Across five orthopedic procedures—including two that were added to the Covered Procedures List for 2026— ASCs consistently post lower total costs than hospital outpatient departments — in some cases by more than $6,000 per case — driven largely by lower facility fees.
However, the patient’s share of the bill doesn’t always follow the same pattern. While ASCs generally mean lower out-of-pocket costs for procedures like rotator cuff repairs, HOPDs carry lower copays for higher-acuity procedures such as total knee replacements.
