What Is Professional Errors and Omissions (E&O) Insurance?
Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. 8,9,10,11
Key Differences in Professional Liability (E&O) Insurance
Alleged harm from professional services
Pie Insurance describes E&O as covering legal fees, costs and damages for claims that business advice or services caused harm, including inaccurate advice, misrepresentation and negligence. Liberty Mutual’s program directory names Physicians & Surgeons Professional and marks it “PL Only.” One page describes alleged professional-service harm; the other names a clinical program category. For either route, compare the proposed form’s covered-services definition, defense treatment and exclusions. 7 3
Audience and policy wording
Pie Insurance frames E&O for professionals whose advice or services may lead to client claims; its product page names examples of occupations that often carry the coverage. Liberty Mutual’s listing identifies physicians and surgeons as a specialty program. A buyer comparing these audiences should request the actual covered-services definition and exclusions from either source of a quote; the listings do not promise that a specific applicant qualifies. 7 3
