Every potential claim turns on its own medical history, evidence, responsible parties, and deadlines. The points below are a starting place—not a substitute for advice about a particular case.
A missed diagnosis alone is not enough
The question is whether the provider responded reasonably to the symptoms, examination, history, risk factors, and available test results. A case may involve failure to order testing, interpret a study correctly, consider a differential diagnosis, obtain a consultation, communicate a critical result, or arrange timely follow-up.
Causation is often the central dispute
The evidence must show that the delay made a meaningful difference. Experts may address whether earlier diagnosis probably would have permitted treatment, avoided progression, reduced surgery, prevented neurological or organ damage, improved survival, or preserved a substantial chance of a better outcome.
Several providers may share responsibility
Diagnostic care often crosses settings and specialties. The review may include primary-care providers, emergency physicians, radiologists, laboratories, specialists, hospitals, nurses, and systems responsible for communicating results or tracking follow-up.
The records should be read as a chronology
Important evidence may include prior complaints, test orders, images, laboratory values, pathology, referral records, portal messages, telephone notes, missed-appointment procedures, and later records documenting the eventual diagnosis.
Cancer claims have a specific timing provision
CPLR 214-a contains a discovery-based rule for certain negligent failures to diagnose cancer or a malignant tumor, subject to statutory conditions and an outside seven-year limit. Other missed-diagnosis claims generally remain subject to the usual rules.
