A Rear-End Collision, a Cervical Spine Surgery, and a Fight Over Pre-Existing Conditions

Stage 2 — SUM Claim

Pre-arbitration settlement

Our client was driving a company vehicle when he was rear-ended by another driver. The impact caused a cervical disc herniation that ultimately required surgical intervention. The at-fault driver carried only a $25,000 liability policy, which we recovered in full. That amount, however, fell far short of compensating our client for the severity of his injuries, the surgery he underwent, and the recovery that followed.

Because the accident occurred in a company vehicle, we identified Supplementary Uninsured/Underinsured Motorist (SUM) coverage on the employer’s commercial auto policy. We filed a SUM claim to pursue the additional compensation our client was entitled to.

The central dispute in the SUM claim was causation. The defense argued that our client’s cervical condition was pre-existing and unrelated to the collision. This is a common tactic in spine injury cases, particularly when imaging shows degenerative changes. We worked closely with our client’s medical team to develop evidence demonstrating that the collision caused the acute herniation and the need for surgery, regardless of any prior degenerative findings. The medical records and expert opinions made clear that our client was asymptomatic before the accident and symptomatic after it.

With discovery underway and arbitration approaching, the case settled for an additional $680,000, bringing the total recovery to $705,000.

How We Built the Case

1 Full Policy Recovery

Recovered the at-fault driver’s entire $25,000 liability policy, exhausting the available coverage.

2 SUM Claim Identification

Identified SUM coverage on the employer’s commercial auto policy, opening a second avenue for recovery.

3 Defeating the Pre-Existing Defense

Developed medical evidence proving the collision caused the acute herniation and the need for surgery, countering the defense’s pre-existing condition argument.

4 Pre-Arbitration Settlement

Secured a $680,000 settlement from the SUM carrier before arbitration, bringing the total recovery to $705,000.

Defense Argument

The SUM carrier argued that the client’s cervical spine condition was pre-existing and degenerative in nature, and that the surgery would have been necessary regardless of the rear-end collision.

Evidence That Won

  • Medical records establishing the client was asymptomatic prior to the collision
  • Post-accident imaging confirming an acute cervical disc herniation
  • Surgical records documenting the necessity of the procedure
  • Medical expert analysis connecting the herniation directly to the rear-end impact
