Low-cost Medicaid managed care plans mostly cut their costs by reducing how much care, and how much high-quality care, their members receive.
That is the conclusion of a new study published by the National Bureau of Economic Research.
According to the study, Medicaid managed care plans succeed in reducing costs less by cost-sharing, negotiating lower provider rates, employing narrow networks, and doing a better job of managing their members’ high-cost chronic medical conditions than they do by leading their members to use fewer high-value, low-cost services such as cancer and diabetes screenings and fewer high-value drugs.
The researchers note that
Effects via quantities, rather than differences in negotiated prices, explain these patterns. Rather than reducing “wasteful” spending, low-spending plans cause broad reductions in the use of medical services – including low-cost, high-value care – and worsen beneficiary satisfaction and health. Supply side tools circumvent the classic trade-off between financial risk protection and moral hazard, but give rise instead to a cost/quality trade-off.
