R89.9
ICD-10-CMUnspecified abnormal finding in specimens from other organs, systems and tissues
This code signifies an abnormal finding identified in a laboratory or pathology specimen originating from an organ, system, or tissue not otherwise specified. It indicates that a deviation from normal was detected, but the specific nature or source of the abnormality is not detailed in the medical record.
This code is appropriate when a pathology report or lab result indicates an abnormal finding in a specimen (e.g., biopsy, fluid analysis) from a non-specific anatomical site, and no more precise diagnosis or abnormal finding code is available. It should be used when the physician's documentation confirms an abnormal result but does not elaborate on the specific type of abnormality or its definitive location.
