Potential Data Breach Important Notice

Impact of Recent Change Health Care (CHC) National Outage

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, Nashville Oncology Associates has not been notified of any specific patients of the practice whose protected health information has been affected by the incident. But in the coming weeks, as a result of this security incident, you may receive a direct notification from Change Health Care indicating that you have been impacted.

Should you be among those affected, Change Health Care has taken steps to address the situation. They have established a dedicated website at www.changehealthcare.com/hipaa-substitute-notice, where you can access valuable resources. Additionally, they have set up a dedicated call center at

866-262-5342, which provides complimentary credit monitoring and identity theft protection for a period of two years to those impacted.

We apologize for any inconvenience caused by this unfortunate event. Thank you for your understanding and patience.
