WellPoint Inc., the second-biggest U.S. health insurer, has picked a new chief executive officer from outside the industry who says his work with hospitals and doctors will help smooth the insurer's path in a time of change. WellPoint named Joseph Swedish, 61, CEO of the nonprofit Catholic hospital system Trinity Health Corp., as its next leader after a six-month search. He replaces Angela Braly, who left WellPoint last year amid investor discontent over the Indianapolis-based insurer's performance.
