What Is Professional Errors and Omissions (E&O) Insurance?

Key Differences in Professional Liability (E&O) Insurance
Published maximum versus named program
Markel Insurance states a maximum of up to $2 million for its miscellaneous E&O product, while cautioning that underwriting, class and the quoted policy control what an applicant receives. Liberty Mutual’s specialty directory names a Physicians & Surgeons Professional program marked “PL Only,” but does not establish a limit for an individual quote. Markel Insurance’s ceiling is a discussion point, not promised capacity; the physician applicant needs the administrator’s proposed limit and retention. 6 3
Miscellaneous and physician-specific audiences
Markel Insurance’s ProBiz page describes a miscellaneous E&O product for its targeted professional classes; the page does not make that a universal eligibility statement. Liberty Mutual’s listing names a specific physician professional-liability program. A business should identify its profession before comparing these categories, then verify whether Markel Insurance’s target class or Liberty Mutual’s program accepts its exact services and entity. The directory alone does not establish a buyer’s eligibility. 6 3
