A pair of medical facilities have come forward and added their names to the list of companies affected by a data breach at American Medical Collection Agency, expanding the list of compromised individuals by 150,000.
More than 24 million individuals have been affected by the breach, which occurred when an unauthorized individual gained access to the collection agency’s web-based payment portal and accessed information for more than eight months. Retrieval-Masters Creditors Bureau, the parent of AMCA, has filed for bankruptcy protection.
The most recent facilities to come forward and announce their unwilling participation in the breach are Mount Sinai Hospital in New York City, and Wisconsin Diagnostic Laboratories. The personal information of about 33,000 patients at Mount Sinai were compromised, and some of those individuals had their financial information compromised as well.
More than 110,000 patients of Wisconsin Diagnostic Laboratories were victimized as part of the breach. For some, their credit and debit card information was stolen, but all of the patients had their names, dates of birth, dates of service, names of lab or medical service providers, referring physicians’ names, balance owed and “other” medical information compromised in the breach.
As with all other companies that have been involved, Mount Sinai and Wisconsin Diagnostic Laboratories have ceased doing business with AMCA.
