Insurance Defense
A fair and equitable decision concerning Workers Compensation benefits depends on thorough, timely, and expert investigation. NBI brings clarity, credibility, and cost-savings to every claim, validating legitimate cases and protecting you against fraudulent allegations.
Confidential Online Case Tracking
Using your secure User ID and Password, NBI's veteran corporate investigators and our encrypted online case tracking portal give you real-time access to your investigation data - including reports, statements, activity logs, billing details, documentation, photographs, and video - all from the privacy and convenience of your office.
AOE/COE Investigations
A robust AOE/COE investigation is critical to evaluating workplace injuries accurately. We proactively pursue subrogation opportunities, document contributory factors, and tailor each probe to your needs - whether for a comprehensive assessment or targeted witness/claimant interviews. Signed medical releases and personnel files are standard inclusions. You receive regular updates, with every report and attachments delivered within 30 days.
Subrosa Surveillance
Our methodical approach accounts for the claimant's lifestyle, context, and environment. Subrosa isn't just luck - it's preparation, intelligence, and execution. NBI is renowned for exceptional video acquisition, ensuring evidence stands up to scrutiny in any adjudicatory process. Choose your preferred delivery: standard VHS, CD, or DVD.
Subrogation
From the outset, we investigate third-party liability. When identified, we compile intelligence on structure and liability carriers, and provide a discreet business/product defect dossier - supplying the leverage required for negotiation or litigation, strengthening your recovery prospects.
