In response to the question regarding the First Report of Injury, which is filed with all except the OIG (Office of Inspector General). When an injury occurs in the workplace, it is standard procedure to file a First Report of Injury.
This report is typically filed with several entities, including: A. the employer of the injured worker, to inform them of the incident and kick-start the workers' compensation process; B. the worker's medical record, to ensure that the injury is documented and treated appropriately.
