21ICD-11 MMS 2026-01
Symptoms, signs or clinical findings, not elsewhere classified
Description
!markdown Clinical findings include those found using physical, laboratory and imaging techniques. Diseases can manifest in many ways and in different body systems. Such specific manifestations may be a reason for treatment or encounter, with or without identifying or addressing the underlying condition. Categories in this chapter include the less well-defined conditions and symptoms that, without the necessary study of the case to establish a final diagnosis, could be designated 'not otherwise specified', 'unknown aetiology' or 'transient'. The conditions and signs or symptoms included in this chapter consist of: - cases for which no more specific diagnosis can be made even after all the facts bearing on the case have been investigated - signs or symptoms existing at the time of initial encounter that proved to be transient and whose causes could not be determined; - provisional diagnoses in a patient who failed to return for further investigation or care; - cases referred elsewhere for investigation or treatment before the diagnosis was made; - cases in which a more precise diagnosis was not available for any other reason; - certain symptoms, for which supplementary information is provided, that represent important problems in medical care in their own right. These categories should be used in conjunction with a code from another chapter that identifies the underlying condition.
