According to a filing with the U.S. Securities and Exchange Commission, LabCorp. said it discovered the breach at a third-party billing collections firm, the American Medical Collection Agency (AMCA), between August 1, 2018, and March 30, 2019.

AMCA believes the breach included patients' personal information, such as financial data, Social Security numbers and medical information, but not lab test results. In addition, the affected AMCA system also included credit card information, bank account information (but no passwords or security questions) and email addresses that were provided by the consumer to AMCA.

Quest Diagnostics disclosed on Monday that 11.9 million customers may have had their medical and financial information exposed. "AMCA has not yet provided LabCorp a list of the affected LabCorp consumers or more specific information about them", the statement added.

In these two breaches alone, roughly 19 million of their customers having been impacted by unauthorized access to the companies' data stored on AMCA's systems.

The growing theft of health care data is drawing scrutiny from key members of Congress.

This is not Quest's first brush with data security issues.

AMCA has reported to BioReference that it is continuing to investigate this incident, has reported the AMCA Incident to law enforcement and has taken steps to increase the security of its systems, processes, and data, including shutting down its web payments page, migrating it to a third-party vendor, and hiring a cybersecurity firm to implement various safeguards to increase security.

Mr. Booker and Mr. Menendez sent a similar letter Wednesday to Stephen Rusckowski, Quest's chairman and president, as did Sen.

"While I am heartened to learn that no evidence now suggests Quest Diagnostic's systems were breached, I am concerned about your supply chain management and your third-party selection and monitoring process", Mr. Warner wrote.

"The months-long leak leaves sensitive personal information vulnerable in the hands of criminal enterprises". "As recently as June 2018 your company faced a lawsuit charging LabCorp with a HIPAA violation for failing to provide adequate privacy protections at its Providence Hospital computer intake station", the Senators wrote.
