Chronic viral hepatitis, unspecified

This code signifies a persistent inflammation of the liver caused by a viral infection, where the specific type of hepatitis virus (e.g., B, C, D) has not been identified or documented. It indicates a long-standing hepatic condition of viral etiology without further specification.

Apply this code when documentation confirms chronic viral hepatitis, but the medical record does not specify the causative virus. This is appropriate when laboratory tests for specific hepatitis viruses are pending, inconclusive, or not performed, yet the chronicity and viral origin are established.

• Avoid using this code if the specific type of chronic viral hepatitis (e.g., B18.1 for chronic viral hepatitis B) is known and documented.
• Always query the provider for clarification on the specific viral type if "chronic viral hepatitis" is documented without further detail.
• This code should be a last resort when no further specificity can be obtained, as more specific codes offer better data for public health and research.
