Our claims center is staffed with specialists who provide assistance when reporting an incident.  Once a claim is reported you can also check its status and, if necessary, locate a doctor via the National Provider Directory.

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.
