A significant cyberattack targeting Change Healthcare, a key technology provider for the health care system, has caused widespread disruption across the United States, with hospitals losing an estimated $100M/day. The attack has compromised personal information, stalled payroll systems, and slowed prescription orders, affecting hospitals, doctors, and pharmacies nationwide. UnitedHealth, which employs 70,000 doctors and controls billing and pharmacy information flow through Change, as well as access to capital through Optum, has been particularly impacted. The company charges fees for the use of its system, and the hack has jeopardized the data of many. Officials have described this as one of the most serious cyberattacks on the U.S. health-care system, threatening some hospitals' solvency. In response, Senator Schumer has called for the FBI to prioritize the case and for CMS to provide accelerated payments to affected health-care organizations. Health providers are urging the Biden administration to intervene, as the attack has left them running low on cash. The attack has also forced patients to make difficult decisions about picking up medications due to pharmacies' inability to confirm coverage.
