To better understand the presence of consolidation in the U.S. health care system, the AAMC Research and Action Institute has published a new data snapshot that compares the market share of providers and insurers to show the implications of consolidation across these two industries. The authors found that, despite concerns from policymakers and the public, the largest health systems by total inpatient hospital discharges have, on average, far less market share – a combined 43.1% of the market share in each state – compared to the top three large-group insurers, which hold an average of 82.2% of the market share in each state. Read more: https://ow.ly/qNWF50RuaGb

Think market consolidation is a problem in #healthcare? You’re right, but let’s start with the insurers (payers). A new data snapshot from the AAMC Research and Action Institute demonstrates the relative market concentration among health care providers and insurers. Across all U.S. states, the largest health systems (by total inpatient hospital discharges) account for about 20% of the state market on average; the largest health insurers account for 50% of the large-group state insurance market. In any given state, the three or four largest health systems combined have an average of 43.1% of the market share, while the top three large-group insurers hold an average of 82.2% of the market share. Check out Alabama on our interactive...can you imagine being a physician practice or community hospital trying to negotiate rates with a payer controlling over 95% of the private market? Insurer consolidation can lead to higher (not necessarily lower) premiums for patients –and lower rates paid to providers, which can result in detrimental effects for patients including discontinued specialized services, hospital closures, and other cuts. Regulators and courts concerned about consolidation must consider all sides of the market for health care goods and services, including the impact of both insurer and provider consolidation on payment rates, patient access, out-of-pocket costs, and quality of care.
