In simple words: This code means a pregnant woman is carrying bacteria called Group B Strep (GBS) which is causing problems with her pregnancy, delivery, or the time after delivery. This code is only used for the mother, not the baby.

This code is for use only on maternal records, never on newborn records.It classifies the presence of a group B Streptococcus (GBS) carrier state in a pregnant woman that complicates the pregnancy, childbirth, or the puerperium (the period after childbirth).The condition must be related to or aggravated by the pregnancy, childbirth, or the puerperium to use this code.Excludes carrier status in non-pregnant women, genitourinary infections during pregnancy, infections of the genitourinary tract after delivery, malignant neoplasms complicating pregnancy, childbirth or the puerperium, maternal care for suspected pelvic organ abnormalities, postpartum acute kidney failure, and traumatic injuries during pregnancy.Additional codes may be needed to specify the related condition.

Example 1: A 35-year-old woman at 37 weeks gestation is found to have a GBS carrier state.She is asymptomatic, but given the risk of neonatal GBS infection, she is prescribed intrapartum antibiotics., A 28-year-old woman develops a GBS infection after childbirth. The infection caused fever and required intravenous antibiotics., A 22-year-old woman with a history of GBS colonization during a prior pregnancy is screened early in her current pregnancy.Prophylactic antibiotics are initiated to prevent recurrence.

Positive GBS culture results from a vaginal or rectal swab obtained during pregnancy or postpartum.Complete obstetric history including previous pregnancies with GBS complications, maternal symptoms (if any), treatment administered, and neonatal outcomes (if applicable).

** This code is part of a larger set of codes used to classify obstetric complications.Always refer to the most current ICD-10-CM coding guidelines for proper use of this code and to ensure accurate billing and reporting.
