Frequently asked questions

What happened? On January 11, 2018, ATI discovered that certain employees’ direct deposit information was changed in our payroll platform. We took immediate steps to mitigate the impact of the incident, and also promptly initiated an internal investigation, with the assistance of third-party forensic investigators, to determine the nature and scope of the incident, including whether any sensitive information was affected. As part of this investigation, ATI recently determined that certain ATI employee email accounts were accessed without authorization between January 9, 2018 and January 12, 2018, and that certain types of patient information were included within one or more of these email accounts.

What information may have been affected by this incident? Recently, ATI determined that one or more of the affected email accounts contained, and the unauthorized actor may have had access to, information related to certain ATI patients, including the following types of information: name, date of birth, driver’s license or state identification number, Social Security number, credit card number, financial account number, patient identification number, Medicare or Medicaid identification number, medical record number, diagnosis, disability code, treatment information, medication/prescription information, doctor’s or therapist’s name, billing/claims information, and/or other health insurance information.. The type of information affected varies per impacted individual. Social Security number was only impacted for a small percentage of the affected population. While our investigation is ongoing, we do not currently have any evidence of actual or attempted misuse of patient information as a result of this incident.

How will I know if I am affected by this incident? ATI will mail notice letters to individuals whose protected information was contained within one or more of the affected emails accounts and may have been accessed by an unauthorized actor.

What is ATI doing? ATI is providing potentially impacted individuals access to free credit monitoring services. Information on these services is included in the notice letters that are being mailed to affected individuals, and can also be found at We have ensured that all employees identified as impacted changed their passwords.
