Other human herpesvirus infection

This code signifies an infection caused by a human herpesvirus other than those specifically classified elsewhere (e.g., herpes simplex, varicella zoster, cytomegalovirus, Epstein-Barr virus, or HHV-6, HHV-7, HHV-8 with specific manifestations). It represents a general category for less common or unspecified herpesvirus infections.

Use this code when documentation confirms a human herpesvirus infection, but the specific type is not identified or is one of the less common types not assigned a more specific ICD-10-CM code. This is appropriate when the physician's diagnosis explicitly states "other human herpesvirus infection" or "unspecified herpesvirus infection" and more specific codes are ruled out.

• Avoid using this code if a more specific herpesvirus infection (e.g., B00.- for herpes simplex, B01.- for varicella) is documented.
• Query the provider for clarification if "herpesvirus infection" is documented without further specification, to determine if a more precise code can be assigned.
• This code is typically used when the specific HHV type (e.g., HHV-6, HHV-7, HHV-8) is identified but the resulting clinical manifestation is not explicitly coded elsewhere.
