Chatham Insurance Services, A Division of DOXA, Launches Aggregate Excess of Loss Program

FORT WAYNE, Ind.— Jan. 26, 2026 — Chatham Insurance Services
(Chatham), a division of DOXA, today announces new aggregate excess of loss coverage designed to help ease the claim volatility among aggregate patient panels. The coverage is written through United States Fire Insurance Company, rated “A+” Superior by AM Best (2025). United States Fire Insurance Company operates under the registered trademark of Crum & Forster (C&F). 

“Providers in value-based care contracts face challenges outside of their control, from claims volatility to opaque benchmarking methodology,” said Chatham Executive Vice President, Excess of Loss – Aggregate, Josh Brickell. “Aggregate excess of loss is a targeted solution, where coverage is explicitly tied to the shared savings or losses that directly impact organizations’ financial performance. By protecting against aggregate losses or guaranteeing shared savings, Accountable Care Organizations (ACOs) can stay focused on what matters most: providing high quality care and maximizing shared savings.” 

Chatham is one of the largest independent management liability insurance program managers serving the managed care industry, with coverages including managed care, errors & omissions (E&O), cyber, directors and officers (D&O), employment practices liability (EPL), crime, fiduciary, identity fraud, kidnap and ransom. In 2024, Chatham leveraged DOXA’s program development capabilities to launch its Excess of Loss (EOL) Specific Division. This latest product offering makes Chatham one of the only providers in the market to offer a full spectrum of solutions to managed care organizations. 

The new aggregate EOL coverage product offerings will support provider
groups engaging in value-based care, including: 

• ACOs participating in Centers for Medicare and Medicaid Services (CMS)
  shared saving programs 

• Providers contracting with commercial payers 

This coverage will provide stability and reliability for the uncontrollable,
providing cost-effective coverage options tailored to each client’s risk preferences using Chatham’s data-driven approach to underwriting and team of aggregate excess of loss experts. 

“Crum & Forster is pleased to partner with Chatham Insurance Services to provide aggregate excess of loss coverage to our managed care insureds and their brokers,” said Tanya Arrowsmith, senior vice president of the Accident & Health Division’s Medical Business Unit at Crum & Forster. “The financial strain caused by claims volatility can make it difficult for managed care organizations to adapt to market changes, maintain regulatory compliance, mitigate risk and more. This aggregate excess loss coverage will provide solutions to many of these challenges, including managing claim costs, providing reinsurance solutions and more. We look forward to working with Chatham to help mitigate these risks facing the managed care industry.” 

Clients benefit from personalized, timely client support, including industry-leading claims processing. 

Chatham’s aggregate EOL coverage is now live. If you are an agent or broker
working with ACOs or provider groups engaging in value-based care, please contact Josh Brickell at Josh.Brickell@chathamins.com to learn how this solution can benefit your clients.
