Zoster with other complications

This code signifies a diagnosis of herpes zoster (shingles) that has resulted in complications beyond the typical dermatological manifestations, but which are not specifically classified elsewhere. These complications can affect various organ systems, indicating a more severe or widespread impact of the viral reactivation.

Apply this code when documentation specifies herpes zoster with complications such as hepatitis, myocarditis, or other systemic involvement not covered by more specific B02 subcategories (e.g., B02.2x for zoster encephalitis, B02.3x for zoster ophthalmicus). The medical record must clearly state the presence of a complication directly attributable to the zoster infection.

• Ensure the documentation explicitly links the complication to the herpes zoster infection.
• Do not use this code if a more specific B02 subcategory exists for the documented complication.
• Sequence this code as the primary diagnosis if the zoster with complications is the reason for the encounter; otherwise, it may be a secondary diagnosis.
