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

## Key Differences in Workers’ Compensation Insurance

### Program structure and advisory route

AIG describes customized workers’ compensation structures involving deductibles, self-insured retentions, captives, or retrospective plans. Marsh McLennan Agency describes arranging coverage and invites organizations to contact an adviser or specialist. Ask MMA which carrier and structure it can place and AIG whether a retained-risk program fits the account. [3](https://www.aig.com/home/risk-solutions/business/casualty "Casualty Insurance - Business Casualty Risk Solutions | AIG US") [7](https://www.marshmma.com/us/services/business-insurance.html "Business Insurance | MMA")

### Safety support and policy detail

Marsh McLennan Agency pairs its workers’ compensation option with safety and prevention support but leaves actual terms to the issued policy. AIG lists the line in corporate casualty and its nationwide motorsports program. Ask MMA which safety services are included and AIG for the proposed policy form, state benefits, and insurer.
