Elevation of levels of liver transaminase levels

This diagnosis code indicates an abnormal laboratory finding where the concentration of liver transaminase enzymes (e.g., ALT, AST) in the blood is higher than the normal reference range. This elevation suggests potential hepatocellular injury or inflammation, but does not specify the underlying cause.

This code is appropriate when laboratory results show elevated liver transaminase levels without a definitive diagnosis for the underlying liver condition. It is often used as a preliminary finding while further diagnostic workup is underway. Documentation should clearly state the specific transaminase enzymes that are elevated and the reported values.

• Do not use this code if a definitive diagnosis for the cause of the elevated transaminases (e.g., acute hepatitis, alcoholic liver disease) has been established.
• Always sequence this code after the definitive diagnosis if one is known and the elevated transaminases are a symptom or manifestation of that condition.
• Ensure the medical record explicitly documents the abnormal lab results and the physician's interpretation of the elevated transaminase levels.
