South Texas Dermatopathology is the last identified casualty of the American Medical Collection Agency (AMCA) data breach. It has reported the data breach to the Department of Health and Human Services Office for Civil Rights (OCR) and informed the affected patients. The OCR breach portal has published information about the breach on October 7, 2019 indicating 15,982 patients were impacted.

AMCA was a business associate of South Texas Dermatopathology, a medical testing laboratory based in San Antonio, TX and provided the company with billings and collection services. In May 2019, South Texas Dermatopathology knew about the breach at AMCA and was informed about the potential compromise of some of its patients’ data because of the AMCA systems hacking.

An unauthorized person first accessed the AMCA systems on August 1, 2018. The person could have accessed the systems up to March 30, 2019 when AMCA detected the breach and secured its systems. During that time period, the unauthorized person got access to areas of AMCA systems that held information like names, addresses, telephone numbers, birth dates, balance data, dates of service, banking or credit card data and treatment provider details.

After knowing about the data breach, South Texas Dermatopathology discontinued giving patient information to AMCA. It ended its business connection with the company and hired another vendor for its billings and collection services. South Texas Dermatopathology has notified all patients impacted by the breach.

The AMCA breach had affected a total of 24 laboratories and healthcare companies resulting in the exposure of patient data.
