— Client Review
When an employee is injured on the job, Workers Comp ensures legitimate claims are honored. But when fraud occurs, companies face financial exposure and increased rates. At NBI, our expert investigators protect your business and validate every claim with impartiality and discretion.
AOE/COE refers to the critical assessment of whether injuries truly arose out of employment or occurred during the course of employment. Our experts meticulously vet every incident, gathering evidence and statements as needed, and often coordinating rapid medical document collection.
With every claim, we recognize timelines are tight. You'll get a full investigative report-complete with attachments and document trails-delivered in 30 days or less.
NBI leverages a secure, cloud-based case management system for real-time reporting, transparent tracking, and robust digital evidence storage. Instantly access statements, documentation, photos, and video as cases develop.
