How Pre-Existing Conditions Affect Workers’ Compensation Claims in Arizona

A work injury can turn your life upside down, but what happens if you already had a pre-existing condition? In Arizona, you can still qualify for workers’ compensation benefits if your job aggravated or worsened your condition. However, proving this can be tricky, as insurance companies often try to deny these claims. Understanding how pre-existing conditions impact your case is essential to securing the benefits you deserve.

How Arizona Law Treats Pre-Existing Conditions

The “Aggravation” Rule

Arizona workers’ compensation law follows the “aggravation” rule, meaning that if your work-related injury worsens a pre-existing condition, you are still eligible for benefits. The key factor is proving that your job made your condition worse beyond its natural progression.

What Insurers Look For

Insurance companies will scrutinize your medical history to argue that your symptoms are due to the pre-existing condition rather than a work-related injury. They will look for:

  • Past medical records showing prior treatment
  • Evidence of ongoing symptoms before the work accident
  • Whether the work incident significantly changed your condition

Proving That Work Made the Condition Worse

Medical Evidence is Key

Strong medical documentation is the foundation of a successful claim. A doctor must confirm that your job aggravated your condition and provide clear evidence of the change. Diagnostic tests, medical reports, and comparative assessments before and after the injury can strengthen your case.

Employer and Coworker Testimony

Witnesses can provide valuable evidence if they noticed your condition worsening due to job-related tasks. For example, if coworkers saw you struggling to lift objects before the injury but noticed a significant decline after an accident, their statements could support your claim.

Prior Medical Records

While past medical records might seem like a disadvantage, they can actually help if they show a clear difference in your condition before and after the workplace injury. These records establish a baseline and highlight the worsening effects caused by work-related activities.

Common Pre-Existing Conditions That Affect Claims

Back Injuries

Many workers have a history of back pain or prior spinal injuries. If a work accident or repetitive strain worsens an existing back problem, you may be eligible for compensation.

Arthritis

Arthritis is common, especially among older workers. If your job activities accelerate joint damage or cause increased pain, your condition may be considered aggravated by work-related factors.

Repetitive Stress Injuries

Conditions like carpal tunnel syndrome or tendonitis often develop over time. If your job exacerbates an existing repetitive stress injury, you may qualify for benefits.

Challenges Claimants Face

Insurance Company Denials

Insurers frequently argue that your condition existed before the injury and that work did not significantly impact it. They may use independent medical exams (IMEs) to downplay your claim.

Delayed Claims Processing

Pre-existing condition cases often face longer processing times because insurers demand extensive medical records and second opinions before approving benefits.
