Infarction of liver

This diagnosis code signifies the death of liver tissue due to an interruption of its blood supply, typically resulting from thrombosis or embolism within the hepatic vasculature. It represents an ischemic injury to the liver parenchyma, which can lead to impaired liver function.

This code is appropriate when documentation clearly indicates an infarction of the liver, often identified through imaging studies (e.g., CT, MRI, ultrasound) showing areas of necrosis or hypoperfusion, or confirmed by biopsy. It is used for conditions such as hepatic artery thrombosis, portal vein thrombosis leading to liver ischemia, or other causes of localized liver tissue death.

• Differentiate from other liver conditions like hepatitis or cirrhosis, which involve inflammation or fibrosis rather than ischemic necrosis.
• Always look for the underlying cause of the infarction (e.g., thrombosis, embolism) and code it as a secondary diagnosis if known and documented.
• Ensure documentation specifies "infarction" or "ischemic necrosis" of the liver, not just general liver injury or dysfunction.
