Matern care for oth or susp poor fetl grth, 2nd tri, fts2

This code signifies maternal surveillance and management for a pregnancy complicated by concerns of inadequate fetal growth in the second trimester, specifically for the second fetus in a multiple gestation. This includes situations where the fetus is smaller than expected for gestational age, but not yet definitively diagnosed as intrauterine growth restriction (IUGR).

Apply this code when documentation indicates maternal care for a suspected or observed growth discrepancy in the second trimester for fetus 2, prior to a confirmed diagnosis of IUGR. This is often supported by ultrasound findings showing fetal biometry below the 10th percentile for gestational age, or a significant discordance in size between fetuses in a multiple gestation.

• Ensure documentation clearly specifies "fetus 2" and the "second trimester."
• Do not use this code if IUGR is definitively diagnosed; instead, use the appropriate O36.51- codes.
• This code requires an additional code from category Z3A to specify the weeks of gestation.
