Synopsis As Introduced Amends the Workers' Compensation Act. Provides that to obtain compensation, an employee has the burden of showing by a preponderance of the evidence that the accidental injury arising out of the course of employment is the major contributing cause of the medical condition or injury for which compensation is sought. Excludes from "arising out of the course of employment" injuries resulting from a hazard or risk to which the general public is also exposed or a medical condition or disability resulting from a personal or neutral risk. Provides that "major contributing cause" of a medical condition or injury is the cause that is greater than 50% of all combined causes of the medical condition or injury. Applies that standard to repetitive injuries. Reduces employer liability for injuries incurred while traveling. Provides for a reduction in an award by amounts an injured worker has previously received for prior injuries that resulted in permanency awards. Reduces certain payments under fee schedules to 49% of the scheduled amount after January 1, 2016. Provides that the Illinois Workers' Compensation Commission, rather than the Director of Insurance, shall adopt rules regarding electronic claims. Makes other changes.
