This bill seeks to expand the types of medical professionals whose services are covered under the Federal Employees' Compensation Act (FECA) by amending chapter 81 of title 5, United States Code. It specifically includes physician assistants and nurse practitioners as "other eligible providers," meaning their services, within the scope of their State-defined practice, will be covered for injured federal workers. The legislation makes conforming amendments throughout FECA to ensure these professionals can provide a range of services, including initial treatment, medical examinations, and second opinions, similar to physicians. This aims to enhance access to necessary medical care for federal employees injured on the job by broadening the pool of recognized healthcare providers. To implement these changes, the Secretary of Labor is mandated to finalize rules within six months of the bill's enactment.
