Antenatal screening for raised alpha-fetoprotein levels in amniotic fluid

This code signifies a diagnostic encounter focused on screening for elevated alpha-fetoprotein (AFP) levels within the amniotic fluid during pregnancy. This screening is performed to identify potential fetal abnormalities, particularly neural tube defects, by analyzing a sample of the fluid surrounding the fetus.

Apply this code when a pregnant patient undergoes an amniocentesis specifically for the purpose of measuring AFP levels to screen for fetal anomalies. This is typically performed as part of a prenatal screening protocol, often following an abnormal maternal serum AFP screen.

• This is a screening code; do not use if a definitive diagnosis of a fetal anomaly has already been established.
• Code any associated abnormal findings or definitive diagnoses separately.
• Ensure documentation clearly states the purpose of the amniocentesis was for AFP screening.
