Health insurer WellPoint Inc. said its chief accounting officer has been removed immediately "without cause" and replaced with a veteran company executive.
The Indianapolis company said Martin L. Miller's departure is not tied to its financial statements or accounting practices.
Miller, 48, joined WellPoint in September 2008 from Molson Coors Brewing Co. and had served as senior vice president, chief accounting officer, controller and chief risk officer.
WellPoint is the largest health insurer based on membership. It operates Blue Cross Blue Shield plans in 14 states.
On Thursday, the insurer's board appointed John E. Gallina, 51, chief accounting officer. Gallina joined WellPoint in 1994 and served most recently as senior vice president of internal audit and continuous improvements. He also has served as a senior vice president of finance since August of 2008.
WellPoint shares fell 50 cents to $76.92 in morning trading.
