Abnormal ultrasonic finding on antenatal screening of mother

This code signifies an unexpected or atypical finding identified during a prenatal ultrasound examination of the mother. It indicates that the sonographic imaging revealed something outside the normal parameters for gestational age or fetal development, requiring further investigation or monitoring. This does not represent a definitive diagnosis but rather an observation that warrants clinical attention.

This code is used when an antenatal ultrasound report documents an abnormal finding, such as an atypical placental appearance, unusual amniotic fluid volume, or a fetal anomaly that is not yet definitively diagnosed. Documentation must clearly state an "abnormal" or "atypical" ultrasound finding during the antenatal period, prompting further workup.

• Do not use this code if a definitive diagnosis for the abnormal finding has been established; instead, code the specific condition.
• Always sequence this code after any definitive obstetric complications or conditions, if applicable.
• Ensure the medical record specifies that the ultrasound was performed during the antenatal period and that the finding was indeed abnormal.
