Workers Comp Claims & Fraud

Insurance Defense

A fair and equitable decision concerning the distribution of Workers Compensation benefits cannot be made without the proper investigative information. A prompt and thorough investigation can yield the truth about a claimant's allegation, justifying the full payment of a valid claim or saving thousands of dollars on fraudulent claims.

If a claim is deemed questionable surveillance(sub rosa) is used to obtain evidence of fraud by capturing the truth about a claimant's condition and comparing what is observed to what the claimant states is their related disability.


A thorough AOE/COE investigation is an essential factor in properly evaluating a workplace injury. We pursue the possibility of Subrogation whenever applicable and list any contribution factors involved. We tailor our investigations to meet your needs, whether it is a full AOE/COE, the claimant's statement only, supervisor, or co-worker and witness statements. Obtaining a signed medical release from the claimant and copies of their personnel file is a standard procedure and your office will be provided with regular updates as to our handling. We maintain an awareness of dates to Accept/Deny and will always complete our handling of matters with a report and attachments to your office within 30 days or less.

National Business Investigations (NBI) uses a cloud-based case management system.  All clients are given access and are asked to create a unique User ID and Password - NBI's secure online case tracking system allows you access to your internal investigation data such as reports, statements, activity, billing information, photographs and video, right from your office computer.

Approached as a multi-step process, we gather intelligence on the claimant by equating their age, family dynamics, profession and employment history, and studying the general layout of the claimant's neighborhood and surrounding area. Although it is a welcomed element, Subrosa is not about being lucky. It is about knowing your subject and having a plan of action. In gathering video evidence, we remain mindful of the thrust of our investigation and identify and obtain whatever evidence is available to be used in adjudication. NBI has a reputation for excellence in the acquisition of video in both content and quality. Claimant video will be provided to you in standard VHS, Compact Disc or DVD format based on your preference.
