Navigating Complex Workers’ Comp Claims: Causation vs. Aggravation

When it comes to workers’ compensation cases, one of the most complex issues involves pre-existing medical conditions. Employers, employees, and insurers may disagree on a claim when a work injury interacts with an existing health issue. As Denver’s leading doctor-owned provider of occupational health services since 1982, Midtown Occupational Health understands that the key to a fair resolution lies in clarifying the difference between aggravation and causation and using objective medical evidence to support claim decisions.

Causation: When a Work Incident Creates a New Injury

Causation applies when an employee sustains a brand-new injury directly caused by a workplace incident. In these cases, the connection between work and the injury is typically straightforward – the injury would not have occurred but for the workplace incident.

Examples of causation include:

• A slip on a wet floor resulting in a fractured wrist.
• A sudden lifting incident leading to an acute herniated disc.

Aggravation: When Work Worsens a Pre-Existing Condition

Aggravation occurs when a workplace activity, accident, or exposure worsens an employee’s existing condition, making it symptomatic or accelerating its progression. In many cases, if the work environment significantly contributes to worsening the condition, even temporarily, the resulting injury is compensable.

Examples of aggravation include:

• An employee with arthritis experiences increased pain and swelling after repetitive kneeling at work.
• A worker with degenerative disc disease develops acute back pain following heavy lifting, requiring medical treatment.

Why the Distinction Matters for Employers

Understanding the difference between causation and aggravation is crucial for managing workers’ compensation claims effectively. This knowledge can help with:

• Claim Eligibility: Many employers mistakenly assume pre-existing conditions disqualify a person from benefits, but many aggravation-related injuries are still covered under workers’ comp.
• Cost Management: Accurate documentation and medical analysis can clarify whether ongoing symptoms are due to the work injury or an underlying issue, which helps control costs.
• Return to Work Planning: Properly differentiating between a new injury and an aggravated condition helps doctors set realistic recovery timelines and work restrictions, supporting a safer return to work.
