Herpes simplex with unspecified complication

This code signifies a diagnosis of herpes simplex infection where a complication is present, but the specific nature of that complication is not documented. It indicates that the herpes simplex virus has led to an adverse effect beyond the typical vesicular lesions, but the precise manifestation of that complication is unknown or unstated.

Use this code when the medical record clearly states a diagnosis of herpes simplex and mentions a complication, but lacks specific details about the type of complication (e.g., "herpes simplex with complication" without further elaboration). Documentation supporting its use would include physician notes indicating a herpes simplex infection with an unstated or unspecified associated complication.

• Avoid using this code if the specific complication of herpes simplex is documented (e.g., herpes simplex keratitis, herpes simplex encephalitis); instead, code to the specific complication.
• This code should be used as a last resort when more specific complication codes are not supported by the documentation.
• Query the provider for clarification on the specific complication if possible, to allow for more precise coding.
