Retrieval Masters/AMCA sending breach notification letters to patients of multiple companies

We have heard reports that Retrieval Masters is sending data breach notification letters to affected individuals. As a bill collector for several medical providers, AMCA had data in its systems from multiple companies, including:

  • Quest Diagnostics – 11.9 million affected
  • LabCorp – 7.7 million affected
  • BioReference Labs / OPKO – over 400,000 affected
  • Carecentrix – 500 affected
  • Sunrise Laboratories – unknown number affected

This list is not exhaustive. If your company is not on this list, you could still be affected. Keep an eye out for a data breach notification letter.

Please note that scammers are aware of the data breach, because it was publicly reported, and may send phishing emails or fake letters. Please verify that these communications are from a legitimate source.

Is Equifax credit monitoring legit?

Some people have been asking whether the free credit monitoring, offered through Equifax, is legitimate.

Equifax is a legitimate company. It is a credit reporting agency that likely already has your Social Security number and other information, because banks and other credit providers often report that information to the three major credit bureaus, Equifax included.

Equifax suffered a massive data breach announced in 2017 that affected 143 million Americans. Our law firm took a lead role in the Equifax data breach lawsuit.

Ultimately, it is your choice whether you want to sign up for the free credit monitoring that Retrieval Masters offers.

Credit monitoring can offer many benefits. Equifax is not the only provider of credit monitoring services. After the Equifax data breach, Equifax reportedly offered free credit monitoring services through Experian.

What to do if your information was breached by Retrieval Masters hack

If you want more information about what to do if you are subjected to a data breach, visit the FTC’s website, There, you should be able to read about credit freezes and fraud alerts and create a recovery plan.

Credit freezes and credit locks can make it more difficult for fraudsters to take out credit cards or other loans in your name. But they can also make it more difficult for you when you want to apply for credit.
