Unspecified viral hepatitis C with hepatic coma

This code signifies a diagnosis of viral hepatitis C where the specific type of hepatitis C is not documented, and the patient is experiencing hepatic coma as a severe complication. Hepatic coma indicates profound liver failure leading to neurological dysfunction.

Use this code when documentation confirms a diagnosis of viral hepatitis C, but the specific genotype or acute/chronic status is not specified, and the patient presents with or develops hepatic coma. This code is appropriate when the provider explicitly links the coma to the unspecified viral hepatitis C.

• Ensure documentation clearly states "unspecified viral hepatitis C" and "hepatic coma."
• Do not use if the type of hepatitis C (e.g., acute, chronic, specific genotype) is known; instead, use a more specific code.
• Sequence this code as the principal diagnosis if the hepatic coma due to unspecified viral hepatitis C is the primary reason for the encounter.
