Humana told 522 members that a limited amount of their personal data may have been exposed during a data security incident at the beginning of 2019, according to ABC affiliate KSAT.
Unauthorized third parties who posed as physician provider groups gained access to the web portal of Humana's service provider, Availity. Using personal information they already had, the third parties requested eligibility and benefit verification of health plan members.
Humana said the breach affected a number of health insurers. Availity uncovered the incident during an internal review Feb. 14. The breach occurred from Jan. 15, 2016, through Feb. 21, 2018, Humana said, according to KSAT.
Humana and Availity said no information indicates that the data, which included name, member IDs, benefit information and provider reminders, was misused.
