A misdiagnosis case generally involves a diagnostic error, a failure to order appropriate testing, or a failure to act on abnormal results in a timely way. In practical terms, that can mean a provider identifies the wrong condition, dismisses serious symptoms too quickly, fails to recognize red flags, or does not follow up after tests come back abnormal. Sometimes the error is obvious only later, when symptoms progress or when another clinician reviews the records and identifies a condition that should have been considered sooner.
In Michigan, these claims may arise from care delivered in many different settings, including primary care offices, urgent care, emergency departments, hospitals, specialty clinics, and outpatient imaging centers. Diagnostic errors can also occur when results are delayed, communicated incompletely, or misunderstood—issues that may not be fully captured by a patient’s memory of what was said during an appointment.
Because medical charts are often detailed but not always easy to connect, a lawyer will typically focus on the timeline. What symptoms were reported, what testing was ordered, what the results showed, how those results were interpreted, and what treatment decisions followed all matter. A misdiagnosis claim is usually built on the relationship between those facts and the harm that occurred.
