Resources for Navigating the Change Healthcare Cyberattack

Have you been affected by the recent Change Healthcare cybersecurity issue?  The following information contains links and resources to help you navigate this challenge.

  • What Happened: On February 21, 2024, UnitedHealth Group discovered a threat actor had gained access to one of its Change Healthcare environments. Once aware of the outside threat, in the interest of protecting its partners and patients, UnitedHealth Group took immediate action to disconnect Change Healthcare’s systems to prevent further impact.
  • Response: Important steps have been taken to mitigate the impact this unprecedented cyberattack on the U.S. health system has had on consumers and those who provide and support care. Ensuring access to care and medications has been the priority, and UnitedHealth Group has worked to address critical challenges related to pharmacy, medical claims and payments. Learn more.
