Hepatitis in viral diseases classified elsewhere

This code signifies inflammation of the liver (hepatitis) that occurs as a manifestation or complication of another primary viral infection. It indicates that the hepatitis is not the primary diagnosis but rather a secondary effect of a systemic viral disease.

Apply this code when documentation clearly links hepatitis to an underlying viral disease that has its own specific ICD-9-CM code. Examples include hepatitis occurring during the course of infectious mononucleosis, cytomegalovirus infection, or other systemic viral illnesses where the hepatitis is not the primary focus of treatment.

• Always sequence the underlying viral disease code first, as this code is for a manifestation.
• Ensure the physician's documentation explicitly states the viral etiology of the hepatitis.
• Do not use this code for primary viral hepatitis (e.g., Hepatitis A, B, C) or hepatitis of unknown etiology.
