Acute and subacute necrosis of liver

This code signifies a severe and rapid onset of liver cell death, either acute (sudden and severe) or subacute (less sudden but still rapid). This condition leads to significant impairment of liver function, often progressing to liver failure.

Apply this code when documentation explicitly states acute or subacute hepatic necrosis. This diagnosis is typically supported by elevated liver enzymes, jaundice, coagulopathy, and encephalopathy, indicating severe liver damage.

• Differentiate from chronic liver conditions; this code is for acute or subacute presentations only.
• Always look for the underlying cause of the necrosis, such as viral hepatitis, drug toxicity, or ischemia, and code it separately if documented.
• Do not use for unspecified liver failure; this code requires documentation of necrosis.
