Payers' market consolidation is worse than health systems'
There has been a large focus on how market consolidation among hospitals and health systems, including physician practice acquisitions, affects competition, pricing, and access to care. However, new data from the Association of American Medical Colleges (AAMC) shows that health payers are actually more consolidated than health systems.
The data released May 1 shows that the largest health systems hold, on average, a combined 43.1% of the market share in each state as measured by total inpatient hospital discharges. In contrast, the top three large-group insurers have an average of 82.2% of the market share in each state.
