Acute viral hepatitis, unspecified

This code identifies an acute inflammation of the liver caused by a viral infection, where the specific type of virus (e.g., Hepatitis A, B, C) has not been determined or documented. It indicates a sudden onset of liver damage due to an unidentified viral agent.

Use this code when the medical record clearly states "acute viral hepatitis" but lacks specific documentation of the causative viral agent. This is appropriate when laboratory tests for specific hepatitis viruses are pending, inconclusive, or not performed.

• Avoid using this code if the specific type of viral hepatitis (e.g., Hepatitis A, B, C, D, E) is documented; use the more specific code.
• Do not use for chronic viral hepatitis; this code is strictly for acute presentations.
• Query the provider for clarification on the specific viral etiology if possible, to allow for more precise coding.
