A misdiagnosis case generally involves a clinician who fails to diagnose a condition correctly or fails to diagnose it early enough to prevent avoidable harm. The error may occur during initial evaluation, when test results are reviewed, when imaging findings are interpreted, or when follow-up is missed after abnormal results. Sometimes the problem is obvious in hindsight; other times it becomes clear only after symptoms progress or treatment doesn’t work.
In Maryland, these cases often arise in circumstances that many residents recognize: a patient is seen multiple times for persistent symptoms, the diagnosis shifts after a second opinion, or the condition is discovered at a later stage when treatment options are more limited. The emotional toll is real. Even when a clinician acted in good faith, the law focuses on whether the care fell below an accepted standard and whether that failure caused measurable injury.
It’s also common for diagnostic issues to involve more than one person or entity. A primary care clinician may order tests, a radiology group may interpret imaging, and a hospital team may manage follow-up. When the diagnostic chain breaks—through missed findings, incomplete documentation, or inadequate escalation—liability can extend beyond a single provider.
