SUBSTITUTE NOTICE

The Chickasaw Nation Department of Health (CNDH) is sharing a substitute notice to notify patients of a security incident occurring from a cyberattack on Change Healthcare (CHC) that has affected a large percentage of the American population. In our delivery of health care, we contract services of CHC in which patients may be affected by this incident.

This notice is from Change Healthcare (CHC) about a recent security incident. Change Healthcare provides services to health care providers, health insurance plans and other companies, from which individuals may have received health services or health insurance. Because Change Healthcare works as a vendor to health care providers or health insurance plans, personal information, including health information, has been impacted in this incident.

CHC is posting this substitute notice to provide customers and individuals with information about the criminal cyberattack on CHC systems and to share resources available to people who believe their personal data potentially being impacted.

CHC is also sharing this website link (called a substitute notice) with additional resources in the Reference Guide for any individual who believes they may be impacted or who may have questions. The link is https://www.changehealthcare.com/hipaa-substitute-notice.

Individuals can visit changecybersupport.com for more information and details about these resources or call the toll-free call center, which also includes trained clinicians to provide support services. The call center can be reached at 1-866-262-5342, and is available Monday through Friday, 8 a.m. to 8 p.m.
