Other herpesviral infection

This code represents a herpesviral infection that is not specifically identified as herpes simplex, varicella zoster, or cytomegalovirus, and does not have a more specific ICD-10-CM code. It covers various less common herpesviruses or unspecified herpesviral infections affecting different body systems. This diagnosis indicates a confirmed herpesvirus etiology without further specification.

Use this code when medical record documentation confirms a herpesviral infection, but the specific type of herpesvirus (e.g., HSV, VZV, CMV) is not identified or a more specific code is unavailable. This is appropriate for infections caused by Epstein-Barr virus (EBV) when not manifesting as infectious mononucleosis, Human Herpesvirus 6 (HHV-6), HHV-7, or HHV-8, or when the documentation simply states "other herpesviral infection."

• Ensure documentation specifies "herpesviral" and not just "viral" to support this code.
• Always look for more specific codes first (e.g., for HSV, VZV, CMV) before resorting to this "other" category.
• Do not use this code for infectious mononucleosis (B27.-) or specific manifestations of herpes simplex or varicella zoster, which have their own dedicated codes.
