Online calculators often produce ranges based on assumptions that may not match how Illinois cases are defended. In practice, the biggest reasons estimates can be misleading are:
- Causation disputes (especially where symptoms can have multiple causes)
- Documentation gaps (missing notes, delayed imaging, incomplete consent forms)
- Pre-existing conditions that insurers argue explain the outcome
- Apportionment of damages—arguments that later treatment (or non-medical factors) contributed to the harm
In a suburban community like Mundelein, many people also have complex care histories—specialists, urgent care visits, and follow-ups across different providers. That can make it harder for insurers to agree on what portion of the harm ties back to the alleged error.
