A significant cyberattack targeting Change Healthcare, associated with UnitedHealth Group, has severely disrupted the U.S. health-care system, affecting hospitals, pharmacies, and doctors nationwide. The attack has compromised personal information, stalled payroll systems, and slowed prescription orders, leading to a situation where hospitals are losing approximately $100M/day. The breach has been described as one of the most serious cyberattacks in U.S. history, threatening the solvency of some hospitals. In response, health-care providers are urging the Biden administration for intervention, with Senator Schumer asking the FBI to prioritize the Change Healthcare hack and CMS to provide accelerated payments to the affected entities. UnitedHealth employs around 70,000 doctors and controls significant health-care billing and pharmacy information through Change, also managing access to capital through Optum. The attack has left many patients facing tough decisions regarding their medications, as pharmacies struggle to confirm prescription coverage.
