Most online calculators work like a simplified spreadsheet: injury severity, length of treatment, and missed work. Real cases don’t behave that neatly.
After a head injury, people often experience symptoms that fluctuate—better one week, worse the next—especially when returning to work too soon. That means the value of your claim often depends less on a single “severity number” and more on whether your medical records show:
- A consistent symptom timeline
- Functional impact (what you can’t do at work or day-to-day)
- Objective findings when available, plus clinician documentation when scans don’t tell the full story
- A credible connection between the incident and your diagnosis
In Washington, insurers may also scrutinize delays in care and inconsistencies in reporting. A calculator can’t address those gaps for you—it can only highlight where your evidence needs strengthening.
