R89.8
ICD-10-CMOther abnormal findings in specimens from other organs, systems and tissues
This code signifies the presence of abnormal findings in laboratory or pathology specimens originating from various organs, systems, or tissues, when a more specific diagnosis is not yet established or available. It represents a non-specific indicator of a deviation from normal physiological parameters identified through diagnostic testing.
This code is appropriate when a pathology report or laboratory result indicates an abnormality in a specimen (e.g., tissue biopsy, fluid aspirate) from an organ, system, or tissue not covered by more specific R-codes (e.g., R87 for genitourinary, R88 for body fluids). It should be used when the physician's documentation confirms an abnormal finding but does not provide a definitive diagnosis.
