Matern care for oth or susp poor fetl grth, 1st tri, fts2

This code signifies ongoing maternal care for a pregnancy where one of the fetuses (specifically fetus 2 in a multiple gestation) is suspected or confirmed to have suboptimal growth, occurring during the first trimester. This includes situations where the fetus is smaller than expected for gestational age, raising concerns for potential growth restriction.

Apply this code when documentation indicates a known or suspected issue with fetal growth for fetus 2 during the first trimester, necessitating maternal monitoring and management. This is supported by ultrasound findings (e.g., biometry measurements falling below expected percentiles) or other clinical indicators prompting further investigation or intervention.

• Always specify the trimester and the affected fetus in multiple gestations.
• Distinguish from codes for confirmed fetal growth restriction (e.g., O36.51-) if the diagnosis is still "suspected."
• Sequence this code as a secondary diagnosis following the primary reason for the encounter if the poor fetal growth is not the sole reason for the visit.
