Massive Quest Diagnostics data breach impacts 12 million patients


AMCA provides billing collections services to Optum360, which is a Quest contractor.

The personal information of millions of Quest Diagnostics lab patients may have fallen into the hands of hackers.

Quest Diagnostics on Monday said almost 12 million of its patients have had personal data exposed as a result of a cybersecurity incident at a billing collections vendor. Quests said it was working with AMCA and Optum360, as well as outside security experts to investigate the incident and its potential impact on its patients.

American Medical Collection Agency, a billing collections service provider, said an "unauthorized user" accessed the agency's system that contained personal information from various entities, including Quest patients, the clinic said in a statement Monday.

But AMCA hasn't yet provided it with "detailed or complete" information about the securiy breach, including which information may have been affected, it said.

"Quest is taking this matter very seriously and is committed to the privacy and security of our patients' personal information".

He and others have indicated that the next move, if any, is up to Congress, which has the power of impeachment. Trump told reporters before boarding the Marine One helicopter "there was no high crime and no misdemeanor".


The company still hasn't received the full details on the breach.

It was only last week that one of New York's largest non-profits, a provider of residential and community care for vulnerable members of society, experienced a similar data breach - albeit on a far smaller scale.

21 News reached out to all ten Quest Diagnostics, but could not get a comment from any of the Quest in the area.

According to Quest, it's not totally their fault.

Quest told CBS it has stopped using AMCA and is alerting patients.
