Decreased fetal movements, second trimester, fetus 2

This code signifies a reduction in the frequency or strength of fetal movements observed during the second trimester of pregnancy, specifically for the second fetus in a multiple gestation. It indicates a potential concern regarding fetal well-being that warrants further investigation.

Apply this code when a pregnant patient carrying twins or more presents with subjective or objectively confirmed decreased fetal activity between 14 weeks 0 days and 27 weeks 6 days of gestation, and the concern pertains to the second fetus. Documentation should clearly specify the trimester and the affected fetus.

• Ensure documentation specifies "second trimester" and identifies "fetus 2" in multiple gestations.
• Distinguish from decreased fetal movements in the first or third trimesters, which have different codes.
• This code is often a primary diagnosis but may be followed by codes for underlying causes if identified.
