UnitedHealth Group has successfully reinstated the pharmacy systems of its Change Healthcare technology unit after a ransomware attack on February 21 disrupted U.S. healthcare system operations. The conglomerate is on track to reactivate its payment platform and begin the restoration of the medical claims network by mid-March, although a complete recovery is anticipated to take several months. Despite the resumption of most pharmacy and payment systems, with over 99% of pre-incident claim volumes flowing, challenges persist for some pharmacies, particularly infusion ones and some Medicaid fee-for-service customers. Additionally, UnitedHealth is addressing issues related to the processing of prescription drug coupons and insurance claims, with most electronic coupons now being processed again and a phased reconnection and testing of the claims system planned for the week of March 18.

The federal government has initiated a HIPAA compliance investigation into UnitedHealth and Change, while providers face substantial cash flow challenges due to delayed payments amounting to an estimated $6.3 billion. Stakeholders have criticized the handling of the situation and the lack of substantial support for affected practices, calling for congressional action and further relief measures to mitigate the ongoing impact of the cyberattack.

The Change Healthcare cyberattack: A timeline Beckers Hospital Review

The recent ransomware attack on UnitedHealth's subsidiary, Change Healthcare, highlights the increasing threat to the U.S. health-care sector from cybercriminals. This breach, occurring over three weeks ago, has disrupted payments to thousands of healthcare providers, underscoring the data-rich sector's appeal to hackers and the devastating impact on patients and physicians. The U.S. Department of Health and Human Services has launched an investigation into the magnitude of this cyberattack, noting its unprecedented scale. The incident not only emphasizes the lucrative market for medical records on the dark web, selling for substantially more than other personal information, but also the sophistication and organizational structure of modern cybercrime operations. These operations, often functioning as ransomware-as-a-service, pose a formidable challenge to healthcare cybersecurity, urgently prompting a reevaluation of defense strategies and investment in data protection.
