Why workers’ comp claims get denied in New Jersey

On Behalf of | Mar 16, 2026 | Workers' Compensation

A workers’ compensation claim can help pay for medical care and lost wages after a workplace injury. But some claims in New Jersey are denied during the first review.

Understanding the most common reasons for denial may help you avoid mistakes that could delay benefits.

How the New Jersey workers’ compensation system works

New Jersey uses a no-fault workers’ compensation system. You may receive benefits for a work injury even if no one intentionally caused the accident.

This system comes from the state’s workers’ compensation law (N.J.S.A. 34:15), often called the “Grand Bargain.” Employees receive medical care and wage benefits after a workplace injury. In exchange, they usually give up the right to sue their employer for negligence. The law outlines these rights in the .

Because the process follows strict rules and deadlines, small mistakes during filing can lead to a denial.

Common reasons workers’ compensation claims are denied

Insurance carriers review injury reports, medical records and employer statements before approving benefits. Several issues often trigger a denial. The most common reasons include:

  • Late injury reporting: Waiting too long to notify your employer may create doubts about when the injury occurred.
  • Insufficient medical evidence: Medical records may not clearly connect your injury to your job duties.
  • Disputed work connection: Insurers may argue the injury happened outside work or during a commute.
  • Preexisting conditions: An insurer may claim the condition existed before the workplace accident.
  • Independent contractor classification: Employers sometimes argue the worker is not covered by workers’ compensation.
  • Misconduct or intoxication: Injuries connected to horseplay or impairment may not qualify for benefits.

These issues often involve documentation problems or disputes about how the injury occurred. Strong medical records and clear reporting can help reduce these risks.

When it may help to speak with an attorney

A denial does not always end a workers’ compensation claim. New Jersey law allows injured workers to challenge denied claims through the Division of Workers’ Compensation.

An attorney may review the denial letter, identify gaps in the evidence and explain how the appeals process works. Legal guidance may also help ensure deadlines are met and the proper documentation is submitted during a dispute.
