Hospital Mergers Drive Up Knee Surgery Costs

The consolidation of hospitals across the U.S. has led to a dramatic increase in healthcare costs, particularly for common procedures like knee replacements. Hospitals with dominant market positions, often formed through mergers, can charge significantly higher prices than their less dominant counterparts.

For instance, a knee replacement at Mission Hospital in Asheville, North Carolina, cost around $40,000 under a specific health plan, while a similar procedure at Catawba Valley Medical Center, an hour away, cost approximately $16,000. This price disparity is attributed to the reduced competition in areas dominated by large hospital systems.

Health economists attribute the steady rise in hospital prices, outpacing other economic sectors, to this ongoing hospital consolidation. Since 2021, mandatory hospital price disclosures have provided data, such as that from Serif Health, enabling a clearer understanding of this link between market power and inflated charges.

While hospital trade groups argue mergers can improve quality and sustainability, evidence suggests otherwise, with examples from Florida and Colorado mirroring the North Carolina situation. Federal and state actions to curb such anti-competitive practices are varied, with some states enacting stricter regulations while federal intervention remains inconsistent.

In Asheville, the formation of Mission Hospital in 1998 through a merger led to concerns about its pricing power. Despite initial state-imposed restrictions, prices continued to climb, especially after these limits were removed and the hospital was acquired by HCA Healthcare. This has resulted in Mission Hospital charging significantly higher rates compared to other hospitals in the region for various procedures.

Beyond the direct cost of procedures, these high hospital prices contribute to increased health insurance premiums for employers and individuals. Patients like Marcelle Crago have reported being quoted vastly different prices for the same surgery, only to find significantly lower costs at outpatient centers not affiliated with dominant hospital systems.

Furthermore, studies indicate a correlation between hospital market dominance and declining quality of care. Regulatory oversight, such as "immediate jeopardy" findings by state health inspectors at Mission Hospital, points to severe patient safety risks. The experience in Asheville serves as a cautionary tale about the unchecked power of hospital monopolies.
