Failure to Treat in Illinois
Average Settlement: $250,000 - $750,000 | Statute: 2 years from the date the plaintiff discovered or should have discovered the injury
About Failure to Treat
Failure to treat occurs when a healthcare provider correctly diagnoses a condition but fails to provide appropriate treatment, refer the patient to a specialist, or follow established treatment protocols. This form of malpractice can be particularly frustrating for patients who sought care, received a correct diagnosis, and then experienced harm because the necessary next steps were never taken. These cases often involve systemic issues such as overloaded physicians, poor follow-up systems, or cost-driven treatment decisions.
