114,000 customers alerted by Wisconsin Diagnostic Laboratories about data breach


Wisconsin Diagnostic Laboratories becomes another victim to notify their patients about the data breach caused as a result of the AMCA (American Medical Collection Agency) incident. The other victims of the AMCA breach included Quest Diagnostics, Clinical Pathology Laboratories, LabCorp, American Esoteric Laboratories, as well as others, totaling 23 affected covered entities and almost 25 million patient records. American Medical Collection Agency is now involved in a breach lawsuit, and their parent company has already filed for bankruptcy.


Wisconsin Diagnostic Laboratories use AMCA for the billing collection services. American Medical Collection Agency alerted the Wisconsin Diagnostic Laboratories by informing them on Jun. 3, 2019, that some of their patients' data that was stored in the AMCA systems were exposed and potentially compromised as a result of unauthorized access that happened in between Aug. 1, 2018, and Mar. 30, 2019.


This data breach incident has not affected the computer systems of Wisconsin Diagnostic Laboratories. The patients who were subjected to the billing collections with American Medical Collection Agency in between Aug. 1, 2018, and Mar. 30, 2019, were only impacted.


For Wisconsin Diagnostic Laboratories, around 115,000 patient records, including names, account balances, dates of birth, medical service providers names or lab names, dates of the medical services, referring doctors, and various medical information related to the services received from or at WDL, have been compromised during AMCA hack.


Some patients also had their bank and credit card information exposed. However, AMCA has confirmed that patients' social security numbers and laboratory test results have not been involved in this incident.


Much like most of the other affected covered entities, Wisconsin Diagnostic Laboratories has stopped doing the business with American Medical Collection Agency as a result of this breach. The officials said that they are currently taking steps, so as to secure and retrieve all Wisconsin Diagnostic Laboratories patient data that was stored in systems of AMCA.


The healthcare organization further has requested all impacted patients to review their bank statements and bills for any kind of suspicious activity.


"We deeply regret any concern or inconvenience this incident may cause our patients. We have ceased doing business with AMCA and are taking steps to retrieve and secure all WDL information contained in AMCA's systems," Wisconsin Diagnostic Laboratories said in one security notice.
