Hawai‘i Medical Service Association suffered a data breach incident in 2016 which exposed the personal information of 10,800 members.
The privacy breach was caused because of an error made with the mailing of care management letters to members.
The emails that were sent to incorrect individuals included information about members' specific health condition, Social Security numbers, or other sensitive personal information.
HMSA immediately responded to the incident and asked the receiving party to delete the emails and notified the impacted persons of the breach.
