Most online tools try to estimate a range using severity and timeframes. In practice, a Zion TBI settlement is driven less by a generic formula and more by how well your medical records line up with the incident and how clearly your life changed afterward.
Insurers tend to focus on:
- Objective documentation (ER records, CT/MRI results when available, diagnoses, and follow-up notes)
- Consistency between what happened, what you reported, and what clinicians recorded
- Functional impact (work restrictions, cognitive limitations, treatment adherence)
- Causation—whether the medical team can reasonably connect ongoing symptoms to the incident
A calculator can’t measure those items. It also can’t account for Illinois dispute patterns, where fault and causation arguments can materially shift settlement leverage.
