Maternal care for excess fetal growth, first tri, fetus 4

This code signifies a pregnancy complicated by a fetus exhibiting excessive growth (macrosomia or large for gestational age) during the first trimester. It indicates that the mother is receiving specialized medical attention and monitoring due to the potential risks associated with an oversized fetus early in gestation.

Apply this code when a pregnant patient in her first trimester is being managed for a fetus diagnosed with or suspected of having excessive growth. Documentation should clearly state the gestational age, the finding of excessive fetal growth (e.g., ultrasound measurements indicating large for gestational age), and the specific fetus (e.g., in a multiple gestation).

• Ensure the documentation explicitly states "first trimester" and identifies the specific fetus (e.g., fetus 4 in a quadruplet pregnancy).
• Do not use this code for excessive fetal growth identified in later trimesters; specific codes exist for those periods.
• Consider co-reporting with codes for underlying maternal conditions contributing to excessive fetal growth, such as gestational diabetes (O24.4-) or pre-existing diabetes (O24.0-O24.3-).
