Pre-existing ailments affect millions of American workers. Arthritis, degenerative disc disease, diabetes and heart conditions do not disqualify you from earning a living, and they generally should not disqualify you from receiving workers’ compensation benefits either.
When a workplace accident or repetitive job duties worsen your health conditions, Kentucky law may provide a mechanism for compensation. The key question remains simple: Did your work make it worse?
Comparing active vs. dormant conditions
Kentucky law makes a sharp distinction between an ailment that bothered you daily and one that stayed quiet:
- Dormant condition: A pre-existing issue that caused no disability or work limitations before the new accident. These often include degenerative changes that exist without causing pain.
- Active condition: A health issue that already limited your ability to work, required ongoing medical care or resulted in a previous disability rating.
A dormant condition “aroused” by a work injury typically qualifies for full benefits, but you must prove that the workplace incident triggered the disability.
If your medical issue was already active, the state may subtract that previous percentage of disability from your new award. This means you only receive compensation for the “new” harm.
The eggshell plaintiff rule may apply
Kentucky also follows the “eggshell plaintiff” rule, which means your employer must accept you as you are. For instance, if you have a vulnerable spine, weak knees or a heart condition, your employer generally cannot use that against you. When work injures you or exacerbates your health, the company remains responsible for the full extent of your harm.
This rule helps ensure fairness for workers who enter the job market with physical limitations. Your employer chose to hire you knowing that all workers bring different health backgrounds to their jobs.
Insurers will likely fight pre-existing condition claims
Insurance adjusters often dig through years of medical records to find any mention of past pain. They may argue:
- Natural progression: Your ailment is simply a result of aging.
- Lack of traumatic event: No specific incident occurred to “arouse” the dormant condition.
- Previous ratings: Old disability ratings suggest you were already “fully disabled” in that particular body part.
These tactics usually save insurance companies money but leave you without the benefits you may be entitled to. They will likely ignore the fact that you performed your duties successfully until the accident occurred.
Proving your workers’ comp claim with medical evidence
A successful claim often relies on clear evidence that connects your work tasks to your current physical state. This proof may include:
- Pre-injury records: Documentation showing you worked without restrictions or pain medication before the accident.
- Physician testimony: A doctor’s statement explaining how the work event “aroused” a dormant condition.
- Diagnostic imaging: Comparisons of MRIs or X-rays taken before and after your injury to show new structural damage.
- Functional capacity exams: Tests that prove your current inability to perform tasks you handled easily in the past.
You need to gather this documentation to build a strong workers’ comp case, especially if your employer’s insurance company attempts to blame your current disability on your past medical history.
Facing billion-dollar corporations alone is risky
Every word in your medical file matters when you fight for the compensation you deserve. These insurance carriers typically employ teams of experts specifically trained to find reasons to say no.
Leveling the playing field involves using the law as a shield to protect your rights and your livelihood. Professional guidance can help ensure that your voice carries weight and that the insurance company treats your filing with the seriousness it requires.
