Maternal postnatal screening for chromosomal anomalies

This code signifies a screening encounter for a mother after childbirth to detect potential chromosomal abnormalities in the infant. It is used when the mother undergoes testing to identify genetic conditions that may have been passed to the newborn.

This code is appropriate for encounters where a postnatal maternal blood test or other screening procedure is performed to assess the risk or presence of chromosomal anomalies in the infant. This often occurs when there are risk factors identified during pregnancy or after birth, or as part of routine follow-up.

• This code is for the mother's encounter for screening, not the infant's diagnosis or screening.
• Do not use this code if a definitive diagnosis of a chromosomal anomaly has already been made for the infant.
• Consider additional codes for any abnormal findings or specific chromosomal anomalies identified in the infant, if applicable to the mother's record.
