Other chronic viral hepatitis

This code signifies a persistent, long-term inflammation of the liver caused by a viral infection other than hepatitis B, C, D, or E. It indicates a chronic viral hepatitis where the specific causative agent is either unknown or not classifiable to a more specific ICD-10-CM code.

This code is appropriate when documentation confirms chronic viral hepatitis, but the specific type (e.g., A, B, C, D, E) cannot be identified or is explicitly stated as "other." It is used when serological tests for common hepatitis viruses are negative or inconclusive, or when the physician specifies an "unspecified" or "other" chronic viral hepatitis.

• Do not use this code if a more specific chronic viral hepatitis (e.g., B18.1 for chronic viral hepatitis B) can be identified from the documentation.
• Always query the provider if the documentation simply states "chronic viral hepatitis" without specifying the type, to determine if a more precise code is warranted.
• Consider sequencing this code after any associated complications of chronic hepatitis, such as cirrhosis (K74.-) or hepatic failure (K72.-), if applicable.
