# Marsh vs USI Insurance Services Workers’ Compensation Insurance

USI documents workers' compensation across three separate practice pages with a named case study; Marsh covers it in one casualty-practice section.

## Research Scope and Use

Use this comparison to evaluate Marsh and USI Insurance Services for Workers’ Compensation Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

USI describes workers' compensation separately for its general property & casualty, private equity and healthcare practices, including one case study with a company-reported EBITDA figure; Marsh McLennan Agency covers the line in one general casualty-practice section.

## What Is Workers’ Compensation Insurance?

Workers’ compensation insurance addresses medical care, rehabilitation and lost wages for employees’ work-related injuries or illnesses. Not every worker, contractor or owner is automatically covered, and not every injury qualifies — check who's included and what's compensable under your state's rules. [12](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [13](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [14](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information")

## Key Differences in Workers’ Compensation Insurance

### How Each Broker Organizes the Line

Both firms broker workers' compensation rather than underwrite it, and neither names an insurer. Marsh McLennan Agency documents the line in a single subsection of its general casualty practice page. [5](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover") [9](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting") [10](https://www.usi.com/property-casualty/private-equity "Private Equity") [11](https://www.usi.com/property-casualty/healthcare/ "Healthcare")

### Services Described for the Line

Marsh applies risk consulting, data-driven claims management and risk analytics across its whole casualty program rather than publishing a workers'-compensation-specific example. [5](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover") USI illustrates its private equity practice's work on the line with one named account:

USI's Private Equity Team cites a case study where it analyzed a manufacturing affiliate's workers' compensation claim trends, ran ergonomics, air-quality and sound-level studies, and helped implement new safety procedures within 90 days; USI says the combined insurance-cost and productivity improvements totaled $1.2 million in EBITDA impact. [10](https://www.usi.com/property-casualty/private-equity "Private Equity") (Evidence: Company-reported; scope: Single named case study on the Private Equity page; company-reported outcome, not independently verified, and not necessarily representative of every account..)

## What to Confirm in Workers’ Compensation Insurance Quotes

- Ask which USI practice — general P&C, private equity or healthcare — would actually handle your account, since eligibility and services differ across the three pages. [9](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting")
- Ask both firms to name the insurer that would issue your policy; neither reviewed page discloses one. [5](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover") [9](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting")
- Ask USI whether the $1.2 million case-study outcome reflects the risk-control services available to your account size, or only the named portfolio company. [10](https://www.usi.com/property-casualty/private-equity "Private Equity")
- Request published limit or experience-modifier targets from USI in writing, since its reviewed pages do not publish general figures beyond that one case study. [9](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting")
