Most online calculators treat a TBI like a checklist: injury severity, treatment length, and time missed from work. But real-world settlement evaluation is more evidence-driven—especially when symptoms are partly subjective (headaches, cognitive fog, dizziness, mood changes).
Insurance adjusters in California frequently focus on three questions:
- Was the accident the cause? (Not just that you were injured, but that the collision mechanism fits the diagnosis.)
- How consistently was the injury documented? (ER notes, follow-ups, therapy records, and clinician observations.)
- What specific functions changed? (Work duties, driving ability, ability to manage daily tasks, and safety concerns.)
A calculator can’t evaluate whether your symptom timeline makes sense with the incident details, whether you followed recommended care, or whether your treating providers described real functional limitations.
