[3](https://www.usi.com/property-casualty/private-equity "Private Equity") [1](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover") ## What Are the Key Differences Between Marsh and USI Insurance Services 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. [1](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover") [2](https://www.usi.com/property-casualty "P&C Insurance and Risk Consulting") [3](https://www.usi.com/property-casualty/private-equity "Private Equity") [4](https://www.usi.com/property-casualty/healthcare/ "Healthcare") Choose USI if you are a private-equity portfolio company, healthcare provider or middle-market employer; choose Marsh McLennan Agency if you want workers’ comp handled with broader casualty risks. [3](https://www.usi.com/property-casualty/private-equity "Private Equity") ### 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. [1](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. [3](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 Should You Confirm in Marsh and USI Insurance Services 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. [2](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. [1](https://www.marshmma.com/us/solutions/casualty.html "Comprehensive Casualty Cover") [2](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. [3](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.
