Amid growing scrutiny statewide, insurance giant Anthem Blue Cross faces another consumer lawsuit over its use of narrow networks in Obamacare coverage. A group of Anthem policyholders sued California's largest for-profit health insurer Tuesday in state court, accusing the company of misrepresenting the size of its physician networks and the insurance benefits provided. A similar suit seeking class-action status was filed June 20 against Anthem, a unit of WellPoint Inc., The Times has reported. Samantha Cowart of Fallbrook sued Anthem in Los Angeles County Superior Court last month, accusing the company of misleading customers.
