Unspecified viral hepatitis with hepatic coma

This code signifies a severe, acute liver failure caused by an unspecified viral hepatitis infection, leading to significant neurological impairment due to the liver's inability to detoxify the blood. Hepatic coma is characterized by altered mental status, ranging from confusion to deep unconsciousness, directly attributable to the liver dysfunction.

Apply this code when documentation clearly indicates a diagnosis of viral hepatitis, but the specific type of virus (e.g., A, B, C, D, E) is not identified, and the patient has developed hepatic coma as a complication. This code is appropriate for cases where the etiology of the viral hepatitis is unknown or not yet determined, but the presence of hepatic coma is confirmed.

• Always attempt to identify the specific type of viral hepatitis if possible, as more specific codes exist (e.g., B15.0, B16.0).
• Ensure documentation explicitly states "hepatic coma" or a similar term indicating severe encephalopathy due to liver failure.
• Sequence this code as the principal diagnosis if it is the primary reason for the encounter, followed by any associated manifestations or complications.
