Reporting A Claim

AmTrust’s professional claims staff has an average of 20+ years of experience, and our claims adjusters maintain low workloads, enabling them to effectively manage claims.  We use an automated claims system and operate in a paperless environment.

Three-point contact is immediately initiated with the injured worker, employer and doctor.  Our Medical Director assists in determining proper diagnoses, provides access to treating physicians and holds peer-to-peer reviews to discuss claims directly with physicians.
