Herpesviral infection, unspecified

This code represents a herpesviral infection where the specific type of herpesvirus (e.g., simplex, zoster, cytomegalovirus) has not been identified or documented. It indicates the presence of a viral infection belonging to the Herpesviridae family without further specification.

This code is appropriate when a clinician diagnoses a herpesviral infection, but the medical record lacks definitive documentation of the specific causative herpesvirus. It can be used when laboratory testing for viral identification is pending or inconclusive, or if the provider simply states "herpesviral infection" without further detail.

• Avoid using this code if a more specific herpesviral infection (e.g., herpes simplex, varicella zoster) is documented.
• Query the provider for clarification if the documentation suggests a specific type of herpesvirus but does not explicitly state it.
• This code should be sequenced as the primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
