Midwest Employers Casualty

What Midwest Employers Casualty does

Midwest Employers Casualty (MEC), founded in 1986 and headquartered in Chesterfield, Missouri, is a specialty insurance carrier focused exclusively on excess workers compensation coverage for self-insured individual employers, groups, and captives in the United States. The company operates as a wholly-owned subsidiary of W. R. Berkley Corporation (NYSE: WRB), a Fortune 500 / S&P 500 commercial lines property-casualty conglomerate, and benefits from A+ (Superior) A.M. Best and AA- (Very Strong) S&P ratings on its insurance subsidiaries. MEC distributes four core products — Individual Excess, Group Excess, Captive, and Large Deductible workers compensation (with deductibles typically starting at $350,000) — exclusively through appointed retail and wholesale agents and brokers nationwide, paying competitive commissions on premium revenue typically under two-year policy terms.

MEC's product platform is augmented by a suite of technology and service modules. The flagship is XCEL Analytics®, a patented AI-driven predictive analytics platform developed in 2013 that processes structured claims data (payroll, loss history, class code distributions) to score risk, prioritize high-loss claims, and trigger early intervention within clients' retained layers. Complementary modules include the Benchmark Report for peer-performance analytics and MEC MSA Solutions, a Medicare Set-Aside optimization service led by in-house Medicare-certified Medical Management Consultants. The company maintains an in-house excess claims organization that includes a board-certified medical doctor (serving as AVP, Claims & Chief Medical Officer), specialized nurse case managers, a National Catastrophic Medical Consultant, and attorneys led by a Chief Claims and Regulatory Counsel — a staffing model MEC describes as unique among excess providers. Dedicated Claim Consult and Client Consult teams operate alongside this clinical and legal bench to reduce costs inside insureds' retained layers, with disclosed outcomes including $2.4 million saved on 230+ complex claims over four years, $70 million in pre-MSA cost savings over seven years, and 99% of claims reimbursements processed within 30 days.
