Viral hepatitis A without mention of hepatic coma

This code signifies an acute inflammatory condition of the liver caused by the hepatitis A virus. It specifically indicates that the patient is experiencing hepatitis A infection without the severe neurological complication of hepatic coma. The infection is typically self-limiting and does not lead to chronic liver disease.

This code is appropriate for documenting a confirmed diagnosis of acute hepatitis A where the patient's clinical presentation does not include signs or symptoms of hepatic encephalopathy. It is supported by positive serological tests for anti-HAV IgM antibodies and clinical findings such as jaundice, fatigue, nausea, and elevated liver enzymes.

• Do not use this code if hepatic coma is documented; a more specific code for hepatitis A with coma would be required.
• Ensure documentation clearly states "hepatitis A" and explicitly or implicitly rules out hepatic coma.
• This code is for acute infection; do not use for past exposure or immunity.
