Hepatic infarction

This code represents an area of necrotic liver tissue resulting from an acute interruption of its blood supply. This can occur due to arterial or venous occlusion, leading to localized tissue death within the liver parenchyma.

Use this code when documentation clearly indicates a diagnosis of hepatic infarction, often identified through imaging studies (e.g., CT, MRI) showing a wedge-shaped or irregular area of hypoperfusion and necrosis. It applies to cases where the liver tissue has undergone ischemic necrosis.

• Ensure documentation specifies "infarction" of the liver, not just ischemia or congestion.
• Investigate the underlying cause of the infarction (e.g., thrombosis, embolism, vasculitis) for potential additional coding.
• Differentiate from other liver conditions like hepatitis or abscess, which involve different etiologies and pathology.
