Maternal care for excess fetal growth, unsp tri, fetus 3

This code signifies a pregnancy complicated by a fetus exhibiting excessive growth, often referred to as macrosomia or large for gestational age (LGA), where the specific trimester of diagnosis is not documented. This condition can lead to complications for both mother and baby, such as difficult delivery, birth trauma, and neonatal hypoglycemia.

Apply this code when the medical record indicates maternal care is being provided due to a fetus with excessive growth, but the documentation does not specify the trimester in which this condition was identified or managed. This is typically supported by ultrasound reports showing fetal biometry measurements significantly above the 90th percentile for gestational age, or a clinical suspicion of macrosomia.

• Always strive for documentation of the specific trimester if possible, as more specific codes exist.
• Do not use this code if the excessive fetal growth is due to maternal diabetes; instead, use codes from category O24.
• Sequence this code as a secondary diagnosis following the primary reason for the encounter, if applicable, or as the primary diagnosis if the encounter is solely for management of excessive fetal growth.
