Wisconsin Diagnostic Laboratories Notifies 114,000 Patients of Data Breach

• Patient information that was contained in AMCA’s systems such as names, dates of birth, dates of medical services, names of lab or medical service providers, referring doctors, balances owed to WDL, and other medical information was compromised.
• In response to this incident, Wisconsin Diagnostic Laboratories (WDL) has ceased doing business with AMCA.

What is the issue?

Wisconsin Diagnostic Laboratories (WDL) becomes the latest victim to notify its patients about a data breach that was caused due to the American Medical Collection Agency (AMCA) incident. WDL use AMCA for billing collection services.

The big picture

American Medical Collection Agency (AMCA) alerted Wisconsin Diagnostic Laboratories on June 3, 2019, that some patients' data stored in AMCA systems had been exposed due to unauthorized access that occurred between August 1, 2018, and March 30, 2019.

This incident did not affect WDL’s computer systems. Only the patients who were subject to billing collections with AMCA between August 1, 2018, and March 30, 2019, were impacted.

What information was compromised?

Patient information that was contained in AMCA’s systems such as names, dates of birth, dates of medical services, names of lab or medical service providers, referring doctors, balances owed to WDL, and other medical information was compromised.

However, AMCA confirmed that patients’ laboratory test results and social security numbers were not involved in the incident.

What was the response?

• In response to this incident, WDL has ceased doing business with AMCA.
• The diagnostic company has taken the necessary steps to retrieve and secure all WDL information contained in AMCA’s systems.
• The healthcare organization has also notified all the impacted patients about the incident and has requested them to review their bills and bank statements for any 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,” WDL said in a security notice.
