Incident Notification

On May 19, 2021, Maximus learned of a cybersecurity incident involving an application related to Medicaid providers’ credentialing and licensing data in Ohio.

Upon discovery, Maximus promptly took the impacted application offline, launched an investigation with a leading cybersecurity firm, activated our response protocols, and notified law enforcement. It was determined that the impacted application was accessed by an unknown party between May 17 and May 19, 2021. This incident did not affect any other Maximus servers, applications, or customers. 

This incident did not affect patient or Medicaid beneficiary information. The incident potentially impacted some personal information about healthcare providers (such as names, dates of birth, and Social Security numbers) provided to the Ohio Department of Medicaid (ODM) or to a Managed Care Plan for credentialing or tax identification purposes. There is no evidence that any of this information has been misused. In an abundance of caution, however, we are offering complimentary credit monitoring services to individuals who may have been impacted by this incident—namely, healthcare providers credentialed through ODM.

Healthcare providers who received a letter regarding this incident or who have questions about credit monitoring services should contact Experian’s dedicated assistance line at (800) 357-0823, Monday to Friday between 9:00AM-11:00PM EDT and Saturday to Sunday 11:00AM-8:00PM EDT.
