Antenatal screening for chromosomal anomalies by amniocentesis

This code signifies the use of amniocentesis as a prenatal diagnostic procedure specifically to screen for chromosomal abnormalities in the fetus. It indicates the intent of the procedure is to identify potential genetic disorders, such as Down syndrome, prior to birth.

Apply this code when amniocentesis is performed for the purpose of genetic screening, often in cases of advanced maternal age, abnormal maternal serum screening results, or a family history of chromosomal anomalies. It is used when the primary goal is to assess fetal chromosomes.

• Ensure documentation clearly states the purpose of the amniocentesis was for chromosomal anomaly screening.
• Do not use this code if the amniocentesis was performed for other reasons, such as fetal lung maturity or infection.
• Pair with procedure codes for amniocentesis and any relevant V-codes for high-risk pregnancy.
