Streptococcus B carrier state complicating the puerperium

This code signifies the presence of Group B Streptococcus (GBS) in a woman during the puerperium (postpartum period), where the GBS carrier state is considered a complication of this period. It indicates that the GBS colonization is clinically significant in the context of the recent childbirth.

Apply this code when documentation explicitly states a GBS carrier state is complicating the postpartum period. This typically involves a positive GBS culture obtained during the puerperium, or a known GBS carrier status from late pregnancy that is being managed or monitored due to potential postpartum complications.

• Ensure documentation clearly links the GBS carrier state as a "complication" of the puerperium, not just an incidental finding.
• Do not use this code for GBS colonization during pregnancy; refer to codes in the O99.82- series for pregnancy.
• Sequence this code as a secondary diagnosis if another puerperal complication is the primary reason for the encounter.
