571.9
ICD-9-CMThis code signifies a persistent, long-term impairment of liver function where the specific etiology is not documented. It indicates a general diagnosis of chronic liver disease without any further detail regarding its cause, particularly excluding alcohol as a contributing factor.
Use this code when the medical record clearly states "chronic liver disease" but provides no additional information about the underlying cause, such as viral hepatitis, autoimmune disease, or metabolic disorders. This code is appropriate when the physician has not yet determined or documented the specific type of chronic liver disease.
