Other infection carrier state complicating the puerperium

This code signifies that a patient in the puerperium (postpartum period) is an asymptomatic carrier of an infectious agent, which is complicating her recovery. This is distinct from an active infection and indicates the presence of the pathogen without overt signs or symptoms of disease.

Use this code when documentation clearly states the patient is a "carrier" of a specific infection (e.g., Group B Strep carrier, CMV carrier) and this carrier state is noted as complicating the postpartum period. This applies even if the patient is not actively ill from the infection.

• Always sequence this code after the code for the specific infection carrier state (e.g., Z22.330 for GBS carrier).
• Ensure documentation explicitly links the carrier state to a complication of the puerperium.
• Do not use this code for active infections; instead, use codes from Chapter 1 for the specific infection.
