Acute hepatitis E

This code identifies an acute inflammatory condition of the liver caused by the hepatitis E virus. It signifies a recent onset infection, often characterized by jaundice, fatigue, nausea, and abdominal pain. The condition is typically self-limiting but can be severe in pregnant women or immunocompromised individuals.

Apply this code when documentation explicitly states a diagnosis of "acute hepatitis E" or "hepatitis E, acute." This diagnosis is typically supported by positive serological tests for anti-HEV IgM antibodies or detection of HEV RNA. Use for initial episodes of the infection, not for chronic carriers or past infections.

• Distinguish from chronic hepatitis E, which is not typically coded with this specific diagnosis.
• Ensure documentation specifies "acute" to differentiate from unspecified or resolved hepatitis E.
• Consider co-occurring conditions like liver failure or encephalopathy, which may require additional codes.
