Change Healthcare Notice

In February, our practice was impacted by the national outage experienced by Change Healthcare because of a cyberattack. Change Healthcare is a healthcare technology company, part of Optum and United Healthcare, that provides services used by much of the US healthcare system, including our practice.

We have remained in close contact with Change Healthcare as they investigate and address this issue.

Change Healthcare has begun issuing customer notifications related to the February 2024 cyberattack. On April 22, 2024, Change Healthcare publicly confirmed the impacted data could cover a substantial proportion of people in America. More recently, on June 20, 2024, Change Healthcare notified our practice’s management company that some of its data was compromised.

At this time, Affiliated Oncologists has not been notified of any specific patients of the practice whose protected health information has been affected by the incident.
