Other viral diseases complicating the puerperium

This code signifies a viral infection, other than those specifically classified elsewhere (e.g., HIV, hepatitis), that arises or persists during the puerperium (the period following childbirth). It indicates that the viral disease is actively complicating the mother's recovery during this postpartum phase.

Apply this code when documentation clearly states a viral disease, such as influenza, varicella, or cytomegalovirus, is present and adversely affecting the patient during the postpartum period. Supporting documentation should include a definitive diagnosis of the viral infection and a clear link to complications during the puerperium.

• Ensure the viral disease is not specifically coded elsewhere within the O98 category (e.g., O98.0-O98.4).
• Always sequence this code as a secondary diagnosis, with the specific viral infection code (e.g., B34.9 for unspecified viral infection) as the primary diagnosis.
• Verify the timing of the viral infection; it must occur or complicate the puerperium, not just be present during pregnancy.
