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

This code signifies ongoing medical supervision and management provided to a pregnant patient in her first trimester due to concerns about the third fetus exhibiting excessive growth. This condition, often referred to as macrosomia or large for gestational age, can lead to complications for both the mother and the fetus.

Apply this code when a pregnant patient in her first trimester is receiving specialized care for a third fetus identified as having excessive growth. Documentation should clearly indicate the gestational age, the specific fetus (e.g., "fetus C" or "third fetus"), and the medical necessity for monitoring and intervention related to the fetal growth.

• Ensure documentation specifies "fetus 3" to differentiate from other fetuses in a multiple gestation.
• Confirm the encounter occurs during the first trimester (weeks 0-13+6 days).
• Code also any associated maternal conditions or fetal anomalies contributing to or resulting from the excessive growth.
