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

This diagnosis code indicates that a pregnant patient in her second trimester is receiving medical care due to concerns about the growth of a fetus (in a multiple gestation pregnancy) that is not meeting expected parameters. This poor growth is either confirmed or strongly suspected, but does not fit the criteria for intrauterine growth restriction (IUGR) or other specified fetal growth issues.

Use this code when documentation indicates maternal care for a fetus in a multiple gestation pregnancy experiencing poor growth during the second trimester, and the specific cause or type of growth restriction is not otherwise classified. This code is appropriate when the provider is monitoring or managing the pregnancy due to concerns about the fetus's size or growth trajectory. Documentation should clearly state "poor fetal growth," "small for gestational age," or similar, for a specific fetus in a multiple gestation, and specify the second trimester.

• Ensure the documentation specifies "second trimester" and refers to "other fetus" in a multiple gestation.
• Distinguish from codes for intrauterine growth restriction (IUGR) (O36.51-) or other specified fetal growth problems (O36.52-).
• Always sequence this code after the primary obstetric code indicating the pregnancy status (e.g., Z3A.xx for weeks of gestation).
