Kaiser Permanente was the only HMO to earn a top four-star rating for providing recommended care on California's annual report card, while Cigna and UnitedHealthcare led the way with three-star ratings among PPO plans. The report issued Wednesday on California's biggest HMOs and other health insurance plans showed improvement in care for children, but mixed results for treating adults with chronic medical conditions. These quality ratings and patient satisfaction scores focus on California's 10 largest HMOs, six biggest preferred-provider organization plans and 209 medical groups covering about 16 million consumers.
