Cigna Corp. exposed private information including bank-account details of some customers in Asia due to a system error, the health insurer said.
The company told Bloomberg it accidentally sent the information to some customers and health care providers in early May. Sabrina Cheung, a Cigna spokeswoman, said that the situation affected a small number of clients who work outside of their home countries, but declined to give a specific number.
She said that the error wasn’t the result of a cyberattack.
“Cigna’s claim system erroneously issued claim settlement communications to certain members and providers,” Cheung said by email. “In some cases, personal information was inadvertently disclosed.”
Health care companies have been under pressure to safeguard consumers’ personal data. The health insurer Anthem Inc. saw the private information of tens of millions of customers exposed by hackers in 2015.
Bloomberg LP uses Cigna to provide medical insurance to employees in some countries in Asia.
