Abnormal results of liver function studies

This code signifies an abnormal finding in laboratory tests designed to assess liver health and function. It indicates that one or more liver enzymes (e.g., AST, ALT, ALP) or other liver function markers (e.g., bilirubin, albumin) are outside the normal reference range, suggesting potential liver injury or dysfunction.

Use this code when documentation indicates abnormal liver function tests without a definitive diagnosis for the underlying cause. This is appropriate for initial workups or when the physician is still investigating the etiology of the abnormal results. Supporting documentation includes lab reports showing out-of-range liver function values.

• Do not use this code if a definitive diagnosis for the liver condition (e.g., hepatitis, cirrhosis) has been established; instead, code the specific liver disease.
• This code is often used as a secondary diagnosis when the primary reason for the encounter is the investigation of these abnormal findings.
• Ensure the medical record clearly states the abnormality and that the provider has not yet determined a more specific diagnosis.
