Sensitive information of Medicaid members potentially exposed, DHS says

MADISON (WKBT) — Data pertaining to certain Wisconsin Medicaid members was accidentally disclosed, the Wisconsin DHS announced Friday.

DHS says on August 8, as part of a cybersecurity investigation, they were notified that a presentation emailed to the DHS Children’s Long-Term Support Council in April 2021 contained protected health information.

This presentation was forwarded to employees working for county government agencies in Rock and other Wisconsin counties and posted to the DHS website as part of the meeting minutes.

Information that was potentially exposed includes the first and last name, date of birth, gender, county location, Wisconsin Medicaid member ID number, and social security number of affected members of Wisconsin Medicaid.

DHS removed the meeting minutes from the website on August 8 and replaced them with a PDF version, which removed access to protected health information. DHS says they also confirmed that people who received those minutes via email deleted the files.

12,358 Wisconsin Medicaid members received notifications that their information may have been accessed by unauthorized individuals. DHS says these affected individuals have been offered free credit monitoring for a year as well as access to a dedicated call center to answer questions regarding the incident.

Medicaid members who have questions can call 833-875-0804 between 8 a.m. and 8 p.m. on weekdays.
