HB0058 Summary

• Requires accidents to be the "prevailing factor" in causing both medical condition and disability for compensability; excludes injuries from idiopathic causes and certain cardiovascular/respiratory events unless accident was the prevailing factor.

• Modifies notice requirements, reducing timeline to 72 hours (with extended 45-day provision) and adds stricter standards for defects in notice affecting employer's ability to investigate.

• Changes disability certification requirements to mandate physician certification using objective medical measurements (range of motion, strength, tissue atrophy) per American Medical Association guidelines, with subjective complaints requiring objective correlation.

• Denies compensation for injuries caused by intoxication or drug use; establishes evidentiary standards including 0.08% blood alcohol concentration threshold and presumptions based on test results.

• Increases Illinois Workers' Compensation Commission to 10 members with enhanced qualification requirements (10 years experience for new commissioners/arbitrators); allows employers and unions to establish alternative dispute resolution systems and collective bargaining agreements on workers' compensation procedures without diminishing benefits.
