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.
What Is Marsh?
Marsh is a global insurance broker and risk advisor. In the United States it places coverage through core Marsh teams and through Marsh McLennan Agency for many middle-market buyers, including technology, cyber, property, casualty and benefits programs. 1,2,3,4
What Is USI Insurance Services?
USI Insurance Services is a U.S. insurance brokerage and consulting firm that arranges property and casualty, employee benefits, personal risk, and retirement programs. Its Technology practice says it works with software, hardware, and related companies from early seed stage through IPO, using a consultative process rather than a published self-serve quote. 6,7,8
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. 12,13,14
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 9 10 11
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 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. 10Company-reported. 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
- Ask both firms to name the insurer that would issue your policy; neither reviewed page discloses one. 5 9
- 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
- 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
