Encounter for antenatal screening for fetal lung maturity

This code signifies a prenatal encounter specifically for assessing the maturity of a fetus's lungs. It involves diagnostic procedures to determine if the fetal lungs are developed enough for extrauterine life, often in anticipation of a planned early delivery.

Use this code when a pregnant patient undergoes testing, such as amniocentesis for lecithin-sphingomyelin (L/S) ratio or phosphatidylglycerol (PG) presence, to evaluate fetal lung maturity. This is typically performed when there's a medical indication for early delivery before full term.

• Do not use for routine prenatal care without specific fetal lung maturity assessment.
• Always code the underlying reason for the fetal lung maturity assessment (e.g., pre-eclampsia, gestational diabetes).
• Ensure the documentation clearly supports the intent of screening for lung maturity, not just general fetal assessment.
