Most online tools use simplified inputs—days hospitalized, “severity” categories, and generic treatment assumptions. Real TBI claims are rarely that tidy.
In practice, insurers in New Jersey look for proof of three things:
- What caused the injury (the accident facts and responsibility)
- What the injury actually did to you (documented symptoms and functional impact)
- How long it lasted and what it required (treatment consistency and ongoing needs)
A TBI calculator may give you a rough range, but it can’t weigh evidence like missed appointments (and why), conflicting symptom reports, or whether your work restrictions were consistent with what clinicians recorded.
