Humana to Sell D.C. Plans to Kaiser: The move by Humana Inc. comes after $30 million in losses this year on the plans and a disappointing second quarter for the company. It also comes as Oakland-based Kaiser Permanente, the nation’s largest nonprofit operator of health maintenance organizations at 7.4 million members, is boosting its East Coast presence. Without disclosing financial terms, Humana’s Humana Group Health Plan unit said it has signed a letter of intent to sell some assets and liabilities to Kaiser Foundation Health Plan of the Mid-Atlantic Region. The agreement would add Humana’s 117,000 members to Kaiser’s 397,000 members in the area, making Kaiser the second-largest operator of HMOs in the Washington area, behind Mid-Atlantic Medical Services Inc. Kaiser would acquire six of Louisville-based Humana’s 10 medical centers and a network of 1,800 doctors.
