Competition in Health Insurance Study Released

Spotlight- AMA report

Earlier this month the American Medical Association (AMA) released the 2020 Update to Competition in Health Insurance: A Comprehensive Study of U.S. Markets based on enrollment data as of January 1, 2019.

The AMA and OSMA used data from previous editions of Competition in Health Insurance to analyze the anticompetitive effects of the Anthem-Cigna and Aetna-Humana proposed mergers.

OSMA has also used data from this report as part of its legislative and regulatory efforts in Ohio—supporting passages of prior authorization and prompt payment reforms.

The publication includes the two largest insurers’ commercial market shares and the Herfindahl-Hirschman Indices (HHIs) for all 384 metropolitan statistical areas (MSAs), the 50 United States, and the District of Columbia. The HHI is a measure of market concentration. The report provides data on 12 different market areas in Ohio.
