Security Update: WellnessFX Customers Not Affected

In a statement released by Quest Diagnostics, the company recently incurred a security incident in which the personal information of 11.9 million customers has potentially been compromised. While Quest Diagnostics system has been affected, we want to let you know that WellnessFX data and systems were not.

Here is what we know:

  • An “unauthorized user” gained access to a system used by American Medical Collection Agency (AMCA), a billing vendor hired by a Quest contractor called Optum360.
  • Quest said the information that may have been exposed included Social Security numbers and medical information, but not test results.
  • Because we don’t share any billing information with Quest, we have no reason to believe that any of our WellnessFX members’ data was compromised
  • In the event that you had any draws done through Quest that were independent from WellnessFX and the WellnessFX experience, you would have to contact Quest to see if the bill(s) were processed via that particular vendor. Quest’s phone number is (866) 697-8378.
  • Quest is taking this matter very seriously and is committed to the privacy and security of their patients’ personal information. Since learning of the AMCA data security incident, Quest has suspended sending collection requests to AMCA.

Please be assured that our engineers have assessed the impact on our systems and none appear to have been directly affected. Our top priority is and will continue to be to keep your data 100% private and secure.
