Matern care for oth or susp poor fetl grth, 2nd tri, fts4

This code signifies ongoing medical management and surveillance provided to a pregnant patient during her second trimester due to concerns about the fetus not growing at an expected rate, specifically for the fourth fetus in a multiple gestation. This "poor fetal growth" is not otherwise specified as intrauterine growth restriction (IUGR) or small for gestational age (SGA) but is a known or suspected issue requiring clinical attention.

Use this code when documentation indicates maternal care for a suspected or confirmed fetal growth issue in the second trimester for the fourth fetus, and the specific type of growth abnormality (e.g., IUGR, SGA) is not yet definitively diagnosed or is described as "other poor fetal growth." This applies when the physician is actively monitoring the growth of the fourth fetus due to clinical findings such as fundal height discrepancies, abnormal ultrasound measurements, or other risk factors.

• Ensure the documentation clearly specifies "second trimester" and identifies the concern as "poor fetal growth" for the fourth fetus.
• Do not use this code if a more specific diagnosis like IUGR (O36.51-) or SGA (O36.52-) is documented for the fourth fetus.
• Always sequence this code as a secondary diagnosis following the primary reason for the encounter, if applicable, or as the primary diagnosis if the sole purpose of the visit is for this maternal care.
