The data breach that potentially exposed the personal and healthcare information of nearly 12 million Quest Diagnostics customers has also possibly affected another 7.7 million customers of fellow lab testing company LabCorp.
In an SEC filing, LabCorp disclosed that its vendor American Medical Collection Agency had a data breach that provided an unauthorized user access to AMCA’s system between August 1, 2018 and March 30, 2019.
The information accessible by the breach included first and last name, date of birth, address, phone, date of service, provider and balance information.
AMCA has told LabCorp that it is in the process of sending notices to the approximately 200,000 of the company’s consumers whose credit card or bank account information may have been accessed and will offer them identity protection and credit monitoring services for 24 months.
A full list of the affected customers has not been shared with LabCorp.
In response to the breach, LabCorp ceased sending new collection requests to AMCA and stopped AMCA from continuing to work on any pending collection requests involving LabCorp consumers.
