Lab Corp: 7.7 Million Consumers Hit in Collections Firm Breach

Summary: LabCorp disclosed in a June 4, 2019 SEC filing that personal and financial data on some 7.7 million consumers was exposed through a breach at third-party billing collections firm American Medical Collection Agency, which persisted from Aug. 1, 2018 to March 30, 2019. AMCA also notified Quest Diagnostics that the same intrusion exposed data on nearly 12 million patients, and LabCorp said AMCA is sending notices to approximately 200,000 of its consumers whose credit card or bank account information may have been accessed.

Bottom line: A billing vendor most patients never chose or heard of held names, dates of birth, service dates, provider and balance data for 7.7 million LabCorp consumers and roughly 12 million Quest patients, and it still has not told either company which individuals were affected.
