The time has come to meaningfully address the most significant driver of health care costs in the United States — the consolidation of provider market power.
Over the last 30 years, our health care markets have consolidated to the point that nearly 95% of metropolitan areas have highly concentrated hospital markets and nearly 80% have highly concentrated specialist physician markets. Market research has consistently found that increased consolidation leads to higher health care prices (sometimes as much as 40% more). Provider consolidation has also been associated with reductions in quality of care and wages for nurses.
In consolidated provider markets, insurance companies often must choose between paying dominant providers supracompetitive rates or exiting the market. Unfortunately, insurers have little incentive to push back against provider rate demands because they have the ability to pass those rate increases directly to employers and individuals, in the form of higher premiums. In turn, employers take premium increases out of employee wages, contributing to the growing disparity between health care price growth and employee wages. As a result, rising health care premiums mean that every year, consumers pay more, but receive less.
