A calculator may ask for inputs like hospitalization length, diagnosis type, or time missed from work. In practice, those variables don’t tell the whole story—especially in head injury cases.
Common reasons calculator ranges fall short:
- Symptoms don’t always match imaging. A scan can be “normal” and you can still have concussion-related impairments.
- Recovery can be non-linear. Better one month and worse the next—typical in some TBI cases—doesn’t fit neatly into a single formula.
- Insurers evaluate consistency. They look for whether your symptom timeline aligns with medical visits, treatment adherence, and functional limits.
- Local proof matters. Police reports, witness statements, and documented accident details can strongly influence how causation is argued.
So, if you used a calculator and felt uneasy about the result, you’re not alone. The better question is: What evidence supports your specific TBI impact?
