A new report from the usually sensible Commonwealth Fund got lots of media attention this past week. The report –“Competition Among Medicare’s Private Health Plans: Does It Really Exist?” –quickly led to headlines like “Is private-sector Medicare becoming a monopoly? [PBS]” and “Robust Medicare Advantage competition almost non-existent [Modern Healthcare],” and “Health insurance is staggeringly uncompetitive in America, and is poised to get even worse for everybody [Quartz].”
It sounds like Medicare Advantage is headed for disaster, but is this really the case?
The Commonwealth report’s major findings are summarized in one sentence, likely the one that grabbed media attention: “Using a standard measure of market competition, our analysis finds that 97 percent of markets in U.S. counties are highly concentrated and therefore lacking in significant [Medicare Advantage] plan competition.”
