## What Is Workers’ Compensation Insurance?

Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. [7](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [8](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [9](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [10](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## Key Differences in Workers’ Compensation Insurance

### Coverage and Safety Support

Marsh McLennan Agency describes workers’ compensation as a business coverage option alongside risk-management support focused on safety and prevention. Insureon describes medical costs and lost wages for employees hurt at work but does not detail safety-prevention services in its overview. If injury prevention is part of your buying decision, ask Marsh McLennan Agency which safety services are included and ask Insureon whether its proposed carrier provides similar support.
