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

This code signifies a pregnancy where the mother is receiving medical attention due to the fetus exhibiting excessive growth (macrosomia or large for gestational age) during the third trimester. This condition can lead to complications during delivery for both mother and baby.

Apply this code when documentation indicates maternal management for a fetus diagnosed with excessive growth after 28 weeks gestation, specifically identifying it as the fourth fetus in a multiple gestation. Supporting documentation would include ultrasound reports confirming macrosomia or large for gestational age, and physician notes detailing the management plan.

• Ensure the documentation clearly specifies "third trimester" and identifies the fetus as the "fourth" in a multiple gestation.
• Do not confuse with codes for fetal growth restriction (O36.5-).
• Always sequence this code as a primary diagnosis when the reason for the encounter is maternal care related to the excessive fetal growth.
