## 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. [9](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [10](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [11](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [12](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## Key Differences in Workers’ Compensation Insurance

### Placement and Coverage Description

Marsh McLennan Agency (MMA) places workers’ compensation within its broader casualty practice and describes benefits for medical expenses, lost wages and other costs after workplace injury or death. Liberty Mutual lists the line in its commercial catalogue and says commercial products are distributed through brokers and agents, but its record does not detail benefits. Compare MMA’s published description with the benefits and exclusions in the Liberty Mutual policy form. [3](https://business.libertymutual.com/claims/policyholder-resources/workers-compensation-resources/ "Workers Compensation Resources") [8](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover")

### Risk Services and Access

MMA lists risk consulting, data-informed claims management and risk analytics across its casualty program, with advisor-led placement through a casualty specialist. Liberty Mutual’s record confirms broker/agent distribution but does not describe workers’ compensation services or application steps. Ask which MMA services apply to your account and what support Liberty Mutual includes.
