A calculator typically uses broad assumptions—injury severity, estimated medical bills, and general categories of harm. That can be helpful for planning, but it can also mislead if your facts don’t match the model.
In practice, insurers in California rarely settle based on a “calculator result.” They look at:
- Whether the provider breached the standard of care (what a reasonable medical professional would do in similar circumstances)
- Whether that breach caused your specific harm (medical causation)
- How your treatment timeline supports or undermines causation
- The documentation quality (clinical notes, imaging/lab reports, discharge instructions)
If your situation involves delayed follow-up, incomplete documentation, or a worsening condition after a discharge—common issues that can happen across outpatient and hospital settings—an online estimate may be too low or too high because it can’t measure those proof problems.
