More than a year after the healthcare reform law sought to prevent sick patients from losing medical coverage, insurers are still paying for their alleged abuses. Blue Shield has agreed to pay $2 million to resolve accusations that the company improperly dropped policyholders after they got sick and needed expensive treatment. The settlement, announced Wednesday by Los Angeles City Atty. Carmen Trutanich, ends an investigation into more than 1,000 so-called rescissions by Blue Shield, a San Francisco-based not-for-profit company.
