The victim count from the American Medical Collection Agency (AMCA) data breach has risen to almost 25 million as yet another healthcare organization has announced it has been impacted by the breach.
Wisconsin Diagnostic Laboratories (WDL), a network of 13 medical testing facilities in and around Milwaukee, is notifying 114,985 patients that some of their protected health information was compromised in the AMCA data breach.
On June 3, 2019, AMCA informed WDL that some of its patients’ data had been compromised as a result of the hacking of a web payment portal. The hacker gained access to the payment page on August 1, 2018. The breach was detected on March 30, 2019 and unauthorized access was terminated.
The types of information in AMCA systems was limited to patients’ names, dates of birth, dates of service, names of lab or medical service providers, referring physician’s name, balances owed to WDL, and other medical information related the services provided by WDL. No Social Security numbers or lab test results were compromised in the breach. A limited number of individuals also had their financial information (credit card number/bank account details) compromised. Those individuals have been notified directly by AMCA.
The only patients affected by the breach were those that had outstanding bills that had been passed to AMCA for collection.
As has been the case with other clients impacted by the breach, WDL has ceased doing business with AMCA and has taken steps to ensure that all patient data held by the company is retrieved and secured.
WDL is the 23rd healthcare organizations to confirm it has been affected by the AMCA data breach. Provisional figures indicate 24,911,500 individuals have been impacted by the breach.
