Herpesviral hepatitis

This code identifies inflammation of the liver caused by a herpesvirus infection. It represents a systemic manifestation of herpes simplex virus (HSV) or other herpesviruses, leading to hepatic dysfunction.

Apply this code when documentation explicitly states herpesviral hepatitis, often seen in immunocompromised individuals or neonates. Supporting documentation should include laboratory confirmation of herpesvirus infection and evidence of liver involvement (e.g., elevated liver enzymes, imaging findings).

• Do not confuse with other viral hepatitides (e.g., hepatitis A, B, C) unless herpesvirus is specifically identified as the causative agent.
• Always code the underlying herpesvirus infection first if a more specific code is available (e.g., B00.0 for herpesviral eczema, B00.1 for herpesviral vesicular dermatitis).
• Ensure documentation specifies "herpesviral" to differentiate from other viral causes of hepatitis.
