General calculators use broad assumptions: injury severity, treatment duration, and lost time from work. But insurance companies in Illinois usually respond to evidence quality—especially for head injuries where symptoms like headaches, dizziness, concentration problems, and emotional changes may not be fully captured on a scan.
In many Decatur cases, the strongest claims show:
- A consistent symptom timeline from the day of the incident onward
- Prompt evaluation after the crash, fall, or workplace event
- Follow-up care (not just one visit)
- Function-based limitations tied to medical advice (work restrictions, therapy recommendations, driving safety concerns)
When that documentation is missing or scattered, an insurer may argue the symptoms were temporary, exaggerated, or unrelated.
