Most online calculators work like a generic worksheet. They may ask for things like hospital time, whether you had imaging, or how long you missed work.
In real Carroll TBI claims, the value usually turns less on the calculator variables and more on:
- How quickly symptoms were documented after the injury
- Whether treatment was consistent (and explained when it wasn’t)
- How clearly doctors linked your symptoms to the accident
- The functional impact—not just the diagnosis
- How fault is likely to be argued based on Iowa accident facts
Because brain injuries can involve symptoms that don’t always show up on a scan, the medical record often carries more weight than people expect.
