Key Differences in Professional Liability (E&O) Insurance

Their published target classes are distinct

Liberty Mutual lists Physicians & Surgeons Professional as a professional-liability-only specialty program. Zurich names technology, manufacturing, and third-party service providers among its E&O classes. If your work is not in the named groups, ask each provider to confirm appetite rather than assuming the program extends to it. 3 6

Zurich describes the protection more fully

Zurich says E&O can address professional-service negligence, mistakes, or failure to deliver promised services, including defense costs, court fees, settlements, and judgments. Liberty Mutual's listing confirms the physician-focused line but does not specify covered allegations, limits, or exclusions. Zurich's description gives technology and service firms scenarios to check against policy language; physicians should obtain the corresponding details from Liberty Mutual. 6 3

Zurich's structure and claims support are described

Zurich describes Pro Plus as a modular suite in one policy and says E&O claims specialists coordinate with legal counsel. Liberty Mutual's reviewed page says specialty programs are administrator-managed but gives no comparable product-structure or claims detail. Confirm which modules and claims contacts apply to the quote you receive. 6 6 3

What to Confirm in Professional Liability (E&O) Insurance Quotes

  • Ask Liberty Mutual for the administrator, issuing insurer, covered medical specialties, policy limits, and exclusions. 3
  • Ask Zurich whether your specific services qualify for Pro Plus, which modules are included, and whether the quote is admitted in your state. 6
