NB aff by (positive) matern group B strep (GBS) colonization

This code signifies a newborn who has been exposed to or affected by maternal Group B Streptococcus (GBS) colonization. It indicates that the mother tested positive for GBS during pregnancy, and this colonization had an impact on the neonate.

Apply this code when a newborn's medical record documents maternal GBS positivity and there's a clinical indication of the newborn being affected by this exposure, even if asymptomatic. Documentation should clearly state maternal GBS colonization and the newborn's status related to it.

• Do not use this code for newborns with confirmed GBS infection; instead, code the specific GBS infection (e.g., sepsis, pneumonia).
• This code is appropriate for newborns exposed to maternal GBS colonization, regardless of whether they received intrapartum antibiotic prophylaxis.
• Sequence this code as a secondary diagnosis when a more specific condition related to GBS exposure (e.g., observation for suspected condition) is the primary reason for admission.
