Other specified acute viral hepatitis

This code signifies an acute inflammation of the liver caused by a viral infection that is not hepatitis A, B, C, D, or E. It encompasses other identified, but less common, viral agents responsible for acute hepatitis. This diagnosis indicates a recent onset of liver inflammation due to a specific viral etiology.

Apply this code when medical record documentation clearly identifies an acute viral hepatitis caused by a virus other than the commonly recognized hepatitis A, B, C, D, or E. This may include cases where a specific non-A-E viral agent is identified, or when the clinician explicitly diagnoses "other specified acute viral hepatitis." Supporting documentation should include laboratory findings confirming a viral etiology and ruling out other common types.

• Ensure the documentation specifies "acute" and identifies a viral cause that is not A, B, C, D, or E.
• Do not use this code for unspecified viral hepatitis; a more specific code exists for that scenario.
• Always review the physician's notes for definitive identification of the viral agent or a clear diagnosis of "other specified acute viral hepatitis."
