How Insurance Companies Save Thousands with a National Biomechanical Document Review

How Insurance Companies Save Thousands with a National Biomechanical Document Review

 

Bodily injury claims continue to represent one of the largest sources of claim exposure for insurance carriers. As medical treatment progresses, claim values can increase rapidly with diagnostic imaging, specialist evaluations, injections, physical therapy, and, in some cases, surgical recommendations.

 

When liability has been established, the next critical question often becomes:

Are the claimed injuries consistent with the mechanics of the accident?

Answering that question can significantly affect claim evaluation, settlement strategy, and litigation decisions.

For many claims, the answer does not require a full vehicle inspection, an accident reconstruction, or an expensive field investigation. Instead, a National Biomechanical Document Review can provide insurance carriers with an independent engineering analysis of whether the reported collision created a biomechanically plausible mechanism for the claimed injuries.

At Garrett Forensics, our biomechanical experts perform document reviews for insurance carriers and defense attorneys throughout the United States, helping clients identify injury claims that are well supported by the accident mechanics—and those that may warrant closer scrutiny.

 

What Is a National Biomechanical Document Review?

A National Biomechanical Document Review is a technical analysis conducted by a biomechanical engineer using the available case documentation rather than an in-person vehicle inspection.

The review focuses on one central question:

Do the physical mechanics of the accident support the injuries being claimed?

To answer that question, the biomechanical expert evaluates the collision dynamics, occupant movement, and claimed injury mechanisms using engineering principles, anatomy, and biomechanics.

Because the review relies primarily on documents already available in the claim file, it can often be completed more quickly and at a lower cost than a traditional field investigation.

 

Documents Commonly Reviewed

Depending on the case, the expert may review:

Police reports
Vehicle photographs
Repair estimates
Vehicle damage reports
Medical records
Emergency department records
Diagnostic imaging reports
Prior medical records
Physical therapy records
Chiropractic records
Deposition transcripts
Recorded statements
Event Data Recorder (EDR) information, when available
Occupant information
Seat belt usage
Airbag deployment information
Photographs of the accident scene

Each document provides information that contributes to understanding the collision mechanics and the potential loading experienced by the occupant.

 

Why Medical Records Alone May Not Answer the Causation Question

Insurance adjusters often receive hundreds or even thousands of pages of medical records.

Those records may document:

Diagnoses
Pain complaints
MRI findings
Treatment recommendations
Surgical consultations
Physical therapy
Injections
Functional limitations

These records establish that treatment occurred.

However, they do not necessarily establish that the motor vehicle accident caused every diagnosed condition.

A physician’s role is to diagnose and treat the patient. A biomechanical engineer evaluates something different—the relationship between the physical event and the claimed injury.

 

The key question is not simply:

“What injury was diagnosed?”

It is:

“Did this accident create the physical forces and body movements necessary to cause that injury?”

Understanding Injury Mechanisms

Every injury requires a physical mechanism.

A cervical disc injury involves different loading than a meniscus tear.

A shoulder injury typically requires different forces than a wrist fracture.

Biomechanical experts evaluate:

Direction of impact
Magnitude of loading
Occupant movement
Body position
Seat belt interaction
Airbag deployment
Interior vehicle contact
Expected joint movement
Force transfer through the body

The claimed injury is then compared with the loading that would reasonably be expected during the collision.

When the accident mechanics and injury mechanism align, the analysis may support causation.

When they do not, further evaluation may be appropriate.

 

Claims That Often Benefit from a Biomechanical Review

Although every case is unique, certain claims frequently benefit from a biomechanical document review.

Low-Speed Rear-End Collisions

One of the most common referrals involves relatively minor rear-end impacts followed by extensive injury claims.

The issue is not whether injuries can occur in low-speed collisions—they can.

Instead, the question is whether the specific accident produced the occupant movement and loading necessary to cause the injuries being claimed.

 

Multiple Body Region Claims

Some claimants report injuries involving the neck, back, shoulders, knees, hips, wrists, and other body regions following a single collision.

Each injury should be evaluated independently.

The mechanics that could load one body region may not reasonably affect another.

A biomechanical review examines whether each claimed injury has a plausible relationship to the collision mechanics.

 

Herniated Disc Claims

Disc bulges and herniations are frequently identified following motor vehicle accidents.

However, these findings may also exist before a collision.

The biomechanical analysis evaluates whether the collision produced spinal loading consistent with the claimed injury mechanism.

 

Shoulder Injuries

Rotator cuff tears, labral injuries, and other shoulder conditions often require specific loading mechanisms.

The expert evaluates whether the occupant experienced direct shoulder contact, forced arm movement, traction, or other loading capable of producing the claimed condition.

 

Knee Injuries

Knee injuries frequently involve twisting, direct impact, compression, or rotational loading.

The review considers whether the occupant’s expected movement supports those mechanisms.

 

Pre-Existing Conditions and Degenerative Findings

One of the greatest challenges in bodily injury claims involves pre-existing medical conditions.

Diagnostic imaging frequently identifies:

Degenerative disc disease
Arthritis
Rotator cuff degeneration
Meniscus degeneration
Cartilage wear
Chronic spinal changes

These findings may have existed before the accident.

A biomechanical review does not attempt to dispute the diagnosis.

Instead, it evaluates whether the reported collision created a mechanism capable of causing a new traumatic injury or significantly aggravating an existing condition.

When prior medical records are available, they can provide valuable context regarding the claimant’s condition before the accident.

 

Evaluating Occupant Kinematics

A critical component of every biomechanical review is understanding how the occupant moved during the collision.

This is known as occupant kinematics.

The expert considers:

Vehicle direction
Collision type
Seating position
Seat belt use
Head restraint position
Airbag deployment
Vehicle rotation
Interior contact points

This analysis helps determine which body regions were likely loaded during the event.

Understanding occupant movement often provides valuable insight into whether the claimed injuries are consistent with the accident mechanics.

 

Saving Money Through Early Technical Evaluation

One of the greatest advantages of a National Biomechanical Document Review is timing.

Rather than waiting until litigation is well underway, insurance carriers can obtain an early engineering assessment of injury causation.

An early review may help:

Clarify injury causation questions
Identify claims requiring additional investigation
Support reserve evaluations
Assist with settlement strategy
Focus additional medical review
Identify inconsistencies between claimed injuries and accident mechanics

Early technical analysis allows claims professionals to make better-informed decisions before claim costs continue to escalate.

 

A Cost-Effective Alternative to Full Reconstruction

Not every claim requires a complete accident reconstruction.

In many cases, sufficient information already exists within the claim file to evaluate injury causation.

A document review can often provide valuable technical insight without:

Vehicle inspections
Scene inspections
Survey work
Additional field investigations
Extensive litigation costs

This makes the service particularly attractive for claims where the primary issue is injury causation rather than liability.

When Should an Insurance Carrier Request a Biomechanical Document Review?

A review should be considered whenever the claimed injuries appear disproportionate to the documented accident mechanics or when injury causation is unclear.

Common referral situations include:

Minor vehicle damage with extensive treatment
Multiple claimed injuries from a single impact
Herniated disc allegations
Rotator cuff or shoulder tears
Knee ligament or meniscus injuries
Delayed medical treatment
Delayed symptom complaints
Significant pre-existing conditions
Degenerative MRI findings
High-value bodily injury claims
Disputed injury causation
Cases approaching mediation or trial

A Technical Review That Can Influence Claim Outcomes

Every bodily injury claim deserves an objective evaluation based on the available evidence.

Medical records establish what treatment occurred.

 

A biomechanical document review helps answer an equally important question:

Does the accident support the injuries being claimed?

By analyzing collision mechanics, occupant movement, body loading, and injury mechanisms, biomechanical experts provide insurance carriers and defense attorneys with valuable technical insight that can influence claim evaluation, settlement decisions, and litigation strategy.

In the appropriate case, identifying injuries that are not biomechanically supported by the accident mechanics can substantially reduce unnecessary claim payments and improve confidence in claim resolution.
