Maternal care for excess fetal growth, second tri, unsp

This code signifies a pregnancy in the second trimester where the fetus is growing larger than expected for gestational age, potentially leading to macrosomia. This condition requires increased monitoring and management by the obstetrician to prevent complications during delivery for both mother and baby.

Apply this code when documentation indicates maternal care for a fetus with suspected or confirmed excessive growth during the second trimester. This typically involves findings from ultrasound measurements (e.g., estimated fetal weight, abdominal circumference) exceeding the 90th percentile for gestational age, or a clinical suspicion based on fundal height.

• Ensure the documentation clearly specifies "second trimester" for accurate code assignment.
• This code is for maternal care due to excessive fetal growth; do not use it for the fetal condition itself.
• Always sequence this code as a secondary diagnosis following the code for the primary reason for the encounter, if applicable.
