Decreased fetal movements, second trimester, other fetus

This code signifies a reduction in fetal activity noted during the second trimester of a multiple gestation pregnancy, specifically pertaining to a fetus other than the first-listed one. It indicates a potential concern for fetal well-being requiring further evaluation.

Apply this code when documentation specifies decreased fetal movements in the second trimester for a twin, triplet, or other higher-order fetus. This is typically supported by maternal report and confirmed by clinical assessment or fetal monitoring.

• Ensure the documentation clearly identifies the affected fetus (e.g., "fetus B" or "second twin").
• Confirm the gestational age falls within the second trimester (weeks 14 through 27+6 days).
• Do not use this code if the decreased movements are attributed to a specific, underlying fetal condition; instead, code the definitive diagnosis.
