R76.9
ICD-10-CMThis code signifies an abnormal result from a blood test related to the immune system, where the specific nature of the abnormality is not documented. It indicates a deviation from normal immunological parameters found in serum, without further specification of the particular immune component affected or the type of finding.
Use this code when laboratory reports indicate an unspecified abnormal immunological finding in serum, and no more specific ICD-10-CM code is available or documented. This is appropriate when the physician has noted an abnormal immune marker but has not yet identified the precise condition or specific antibody/antigen involved.
