Acute hepatitis B with delta-agent with hepatic coma

This code signifies an acute infection of the liver caused by the hepatitis B virus, complicated by co-infection with the hepatitis D (delta) agent, which has progressed to hepatic coma. This represents a severe and life-threatening manifestation of viral hepatitis.

Use this code when documentation clearly indicates acute hepatitis B with a confirmed delta agent co-infection, and the patient is experiencing hepatic coma as a direct result of this infection. Supporting documentation would include laboratory confirmation of acute HBV and HDV, along with clinical findings consistent with hepatic encephalopathy progressing to coma.

• Ensure documentation specifies "acute" hepatitis B and the presence of the "delta agent."
• Verify that hepatic coma is explicitly documented and linked to the acute hepatitis B/delta co-infection.
• Do not use this code for chronic hepatitis B with delta agent, or for acute hepatitis B without delta agent co-infection.
