Maternal care for excess fetal growth, third tri, fetus 1

This code signifies antenatal care provided to a pregnant patient in her third trimester due to concerns of a single fetus exhibiting excessive growth. This condition, often referred to as macrosomia or large for gestational age, can lead to complications during delivery for both mother and baby.

Use this code when documentation indicates a maternal diagnosis of excessive fetal growth (e.g., macrosomia, large for gestational age) specifically for the first fetus during the third trimester of pregnancy. Supporting documentation includes ultrasound reports showing estimated fetal weight above the 90th percentile for gestational age, or clinical assessment indicating a fundal height significantly larger than expected.

• Always confirm the trimester of pregnancy and the specific fetus (if multiple gestations) to ensure accurate code selection.
• Do not confuse this with codes for fetal growth restriction (IUGR), which describes insufficient growth.
• This code requires an additional code from category Z3A to specify the weeks of gestation.
