A cyberattack on UnitedHealthcare's unit Change Healthcare, a division of Optum, when it was discovered (February 21st), disrupting prescription drug orders at pharmacies and continues to have effects on the entire health care system, leading to major challenges in reimbursement and claims processing for health care professionals and pharmacies. Law enforcement officials indicate the breach appears to be by a foreign country, with the ransomware gang "Blackcat" being identified behind the outage. UnitedHealth Group was forced to disconnect some of Change Healthcare's digital network from its clients, and had not been able to restore all services. The Health Information Sharing and Analysis Center (Health-ISAC) issued a bulletin (https://tinyurl.com/4nn3df7x)providing information regarding maintaining network connectivity with UnitedHealth Group, Optum, and UnitedHealthcare. The American Hospital Association has also published a Cybersecurity Advisory (https://tinyurl.com/2sb8667j) (February 26th) to help navigate this evolving incident. The attack underscores the vulnerability of health care data. The Delaware Department of Insurance issued an announcement (https://tinyurl.com/y57apn26) regarding this attack. The communication indicated that Insurers have been in contact with the Delaware Department of Insurance about this issue and are in communication with contracted providers to inform them of available portals and processes. The Delaware Insurance Data Secrity Act has not yet been triggered, but all parties continue to watch the situation closely. Additionally, the department will be closely monitoring any potential prompt payment compliance issues that may arise as a result of this situation. At this time, there is no indication that consumer data or insurer data has been impacted. However, consumers are still encouraged to engage in personal cybersecurity practices at an enhanced level.
