Morning Read: The end of health insurance M&A?

Highlights of the important and the interesting from the world of healthcare:

The end of health insurance M&A? Maybe not the end, but clearing regulatory hurdles likely will become much more difficult. The Justice Department is looking to step up antitrust enforcement of health insurance mergers, because much of the health reform law’s success depends on a competitive (or at least somewhat competitive) insurance market. The goals of reform “cannot be achieved” if insurer mergers reduce competition, or if big companies use their market clout to keep out upstarts, the agency’s antitrust chief said. With most markets dominated by one or two big health insurers, one could argue that it’s a little late to finally start worrying about oligopolies.
