Quest Diagnostics Patient Data Breached

Quest Diagnostics Patient Data Breached

Quest Diagnostics and LabCorp announced this week that they were the victims of a data breach between August 2018 and March 30, 2019, according to the Better Business Bureau.

"While I am heartened to learn that no evidence now suggests Quest Diagnostic's systems were breached, I am concerned about your supply chain management and your third-party selection and monitoring process", Mr. Warner wrote.

The system contains sensitive data, including credit card numbers, medical information, social security numbers, and bank account information, Quest said.

In a filing with the Securities and Exchange Commission, LabCorp revealed that the stolen data includes a patient's name, date of birth, address, phone number, date of service, provider, and balance information.

On Monday, 7th of June, American Medical Collection Agency (AMCA) informed Opko Health, one of the largest health organizations in the word, of its payment site compromise that affected 422,600 customers.

OPKO itself stated that no laboratory results or diagnostic information were exposed to unauthorized parties.

It is unclear if any payment information associated with Quest was impacted.

Christian Marbach, a spokesman for the affected families whose grandfather was among the victims, doubted Hoegel's sincerity. Hoegel was convicted in 2015 of two murders and two attempted murders and is already now serving a life sentence.


Opko Health said its affected unit, BioReference Laboratories Inc, suspended collection requests to AMCA since October past year, and has asked the vendor to stop working on any pending collection requests involving the company's customers.

AMCA is yet to provide Quest with full or detailed information on the infringement and was unable to verify its accuracy, Quest said.

In response to the breach, LabCorp ceased sending new collection requests to AMCA and stopped AMCA from continuing to work on any pending collection requests involving LabCorp consumers.

This is not Quest's first brush with data security issues.

AMCA said in an emailed statement it is investigating the incident and has also hired an external forensics firm. The AMCA also told Quest and Optum that it has been in contact with law enforcement about the incident.

According to its website, AMCA is the "leading recovery agency for patient collection" and it is "managing over $1BN in annual receivables for a diverse client base", servicing "laboratories, hospitals, physician groups, billing services, and medical providers all across the country".
