What Are the Key Differences Between Coterie Insurance and Liberty Mutual Professional Liability (E&O) Insurance?

Published limit and reporting choices

Coterie Insurance’s MPL brochure lists per-claim options of $25,000, $50,000, $250,000, $500,000 and $1 million, aggregate multiples tied to each option, a basic 60-day extended reporting period, optional longer extensions and prior acts. Liberty Mutual’s program directory names a physician PL-only offering but does not establish quote-specific limits or reporting terms. Coterie Insurance publishes figures for comparison; the Liberty Mutual administrator must provide the proposed schedule. Both remain subject to the actual form and underwriting. [2] [5]

Policy trigger and audience

Coterie Insurance describes its MPL as claims-made, with a retroactive date and reporting during the policy period or an extension. Liberty Mutual identifies the Physicians & Surgeons program but does not establish its trigger in that listing. A buyer moving between forms should compare the retroactive date and reporting extension rather than assume the physician label uses the same structure. Coterie Insurance also lists profession-specific eligibility and state restrictions, so the applicant’s class and location belong in the submission. [2] [5]

What Should You Confirm in Coterie Insurance and Liberty Mutual Professional Liability (E&O) Insurance Quotes?

  • Confirm with Coterie Insurance which state, profession, selected aggregate and retroactive date appear in the quote. [2]
  • Ask Liberty Mutual’s administrator for the physician program’s proposed limit, trigger and extended-reporting terms. [5]

Coterie Insurance lists MPL per-claim options of $25,000, $50,000, $250,000, $500,000 and $1 million, with aggregate and reporting-period terms; Liberty Mutual names a Physicians & Surgeons PL-only program.
