IL HB4630

Amends the Workers' Compensation Act to strengthen the rebuttable presumption for firefighters, EMTs, paramedics, and related emergency personnel that specified health conditions (bloodborne pathogens, MRSA, lung/respiratory disease, heart/vascular disease, hypertension, tuberculosis, cancer, hernia, and hearing loss) arise from employment.

Shifts the burden of proof to the employing entity, requiring them to establish by clear and convincing evidence an independent, non-work-related cause and prove that no aspect of employment contributed to the condition.

Makes the hearing loss presumption irrebuttable against evidence showing the employee did not meet exposure thresholds listed in Section 8 of the Workers' Compensation Act.

Applies only to employees with at least 5 years of service as a firefighter, EMT, or paramedic when filing their claim, with an exception for private employer EMTs/paramedics who spend most of their work time on non-emergency medical transfers.

Clarifies that workers' compensation findings under the rebuttable presumption are not admissible or binding in disability claims under the Illinois Pension Code.
