Antenatal screening for Streptococcus B

This code identifies a screening encounter during pregnancy specifically for the presence of Group B Streptococcus (GBS). GBS is a common bacterium that can be passed from a mother to her baby during childbirth, potentially causing serious infections in the newborn.

This code is used when a pregnant patient undergoes routine screening for GBS, typically in the late second or early third trimester. It applies to encounters where the primary purpose is to determine the GBS status of the mother, regardless of the test result.

• This code is for screening only; do not use if the patient is symptomatic for a GBS infection.
• Assign this code as a secondary diagnosis when the primary reason for the encounter is routine prenatal care.
• Ensure documentation clearly indicates the purpose of the visit was GBS screening.
