This bill modernizes the Federal Employees' Compensation Act, which provides benefits to injured federal workers, by requiring injured employees to receive medical care through managed care networks contracted by their federal agencies rather than selecting providers freely. The legislation aims to reduce costs, combat fraud, and improve treatment outcomes by implementing standardized treatment protocols, cost controls, and fraud detection tools that federal employers can direct. Federal agencies must contract with managed care networks within one year of the law taking effect, though employees can still see out-of-network providers in emergencies or when the network cannot provide needed services, and they have the right to request second opinions. The Secretary of Labor will establish treatment standards, create a 16-member review board to oversee compliance and performance, and can use artificial intelligence to identify potentially fraudulent claims. A Government Accountability Office review is required six years after enactment to assess the law's effects on costs, fraud reduction, and administrative efficiency.
