Long Beach-based Molina Healthcare, a major insurer in Medicaid and state exchanges across the country, has shut down its online patient portal as it investigates a potential data breach that may have exposed sensitive medical information.
The company said that it closed the online portal for medical claims and other customer information while it examined a “security vulnerability.” It’s not clear how many patient records might have been exposed and for how long. The company has more than 4.8 million customers in 12 states and Puerto Rico.
Molina posted $17.8 billion in annual revenue last year. The company made news earlier this month with the surprise firing of its top two executives, who are sons of the company’s founder. Both CEO J. Mario Molina and his brother, finance chief John Molina, were ousted. The company’s board said Molina’s disappointing financial performance led to the management change.
