Symptoms, signs or clinical findings, not elsewhere classified is a chapter in ICD-11 that includes clinical manifestations and abnormal findings that indicate a possible health condition but cannot be assigned to a more specific disease category. These entries represent patient-reported symptoms, observable signs, or diagnostic findings that may occur alone or in association with a wide range of underlying disorders.
This chapter covers diverse presentations such as pain, fatigue, abnormal laboratory results, and unexplained physical findings. Classification within this chapter supports accurate documentation, clinical assessment, and further diagnostic evaluation, while also enabling consistent reporting, research, and health system analysis when a definitive diagnosis has not yet been established.
