The House healthcare bill would repeal an exemption from federal antitrust oversight that the health-insurance industry has enjoyed for decades, but the move alone might not make local insurance markets more competitive. The repeal is necessary to inject competition into regional insurance markets, according to Rep. Diana DeGette (D., CO), one of several members of Congress behind a push to repeal the exemption. She cited American Medical Association figures showing that 94% of those markets are highly concentrated.
