Encounter for antenatal screening for fetal macrosomia

This code signifies a prenatal encounter focused on assessing the fetus for potential excessive growth, specifically macrosomia. It involves screening procedures and evaluations performed during pregnancy to identify fetuses at risk of being significantly larger than average for their gestational age.

This code is appropriate for encounters where a pregnant patient undergoes screening for fetal macrosomia due to risk factors such as gestational diabetes, previous macrosomic infant, or high maternal weight. It should be used when the primary purpose of the visit is to evaluate for this specific fetal condition, often involving ultrasound measurements.

• Do not use this code if macrosomia has already been definitively diagnosed; instead, use the appropriate O-code for confirmed fetal macrosomia.
• This code is for screening purposes only, not for the management of established macrosomia.
• Always code in conjunction with other relevant codes, such as the patient's gestational age and any underlying risk factors.
