Maternal care for excess fetal growth, second trimester, oth

This code signifies antenatal care provided to a pregnant patient in her second trimester due to concerns of a fetus exhibiting excessive growth. This condition, often referred to as macrosomia or large for gestational age (LGA), suggests the fetus is growing larger than expected, potentially leading to complications during delivery.

Apply this code when documentation indicates maternal management for a fetus with suspected or confirmed excessive growth during the second trimester (weeks 14-27+6 days). This typically involves increased fetal surveillance, such as serial ultrasounds to monitor fetal size and growth trajectory, and potentially gestational diabetes screening or management.

• Ensure the medical record explicitly states "second trimester" and "excessive fetal growth" or "macrosomia" for a specific fetus.
• This code requires a seventh character for the specific fetus (e.g., 0 for not applicable or unspecified, 1 for first fetus, 2 for second fetus, etc.). The '9' in the provided code indicates "other fetus."
• Always sequence this code as a secondary diagnosis, with the primary diagnosis reflecting the reason for the encounter (e.g., routine prenatal visit, abnormal ultrasound finding).
