Scott+Scott Attorneys at Law LLP (“Scott+Scott”), a national consumer rights and shareholder litigation firm, is investigating potential claims concerning a data breach involving American Medical Collection Agency, Inc. (“American Medical”) that impacted more than 20 million patients of at least three medical laboratory testing firms, including approximately 12 million Quest Diagnostics Incorporated (“Quest”) patients; 7.7 million Laboratory Corporation of America Holdings (“LabCorp”) patients; and nearly 423,000 BioReference Laboratories (“BioReference”) patients. American Medical provides billing collections services to revenue cycle management to laboratories throughout the United States.

According to the U.S. Securities and Exchange Commission (“SEC”) filings of Quest and LabCorp, American Medical claims it learned from a third-party security firm of unauthorized activity on American Medical’s web payment page occurring between August 1, 2018, and March 30, 2019.

According to the SEC filings of the companies impacted by the breach, potentially compromised data includes patients’ healthcare and financial information, ranging from name, date of birth, address, phone, date of service, provider, balance information, and in some cases, bank account information and social security numbers.
