MI HB5186

Increases weekly compensation rate from 80% to 90% of an employee's after-tax average weekly wage for total or partial disability due to work-related injuries

Raises the maximum weekly compensation rate from 90% to 150% of the state average weekly wage, effective the January 1 after the amendatory act takes effect

Eliminates coordination of worker's compensation benefits with Social Security old-age insurance benefits, removing the previous 50% offset for Social Security payments

Creates annual cost-of-living adjustments for employees after 1 year of continuous disability, tying benefit rates to changes in the state average weekly wage

Expands compensable injuries to include work that "accelerates or worsens a symptom" regardless of preexisting conditions, and adds new specific loss categories including serious facial disfigurement (52 weeks) and serious impairment of important body functions (52 weeks)

Establishes enhanced anti-retaliation protections, requiring employers who discriminate against employees for filing claims to pay 100 weeks of the employee's average weekly wage as a penalty
