Decreased fetal movements, third trimester, other fetus

This code signifies a reduction in the frequency or intensity of fetal movements experienced by the pregnant patient during the third trimester, specifically when referring to a fetus other than the primary one in a multiple gestation pregnancy. It indicates a potential concern for fetal well-being requiring further evaluation.

Use this code when documentation explicitly states decreased fetal movements in the third trimester for a non-designated fetus in a multiple pregnancy. This typically arises during routine prenatal visits or when the patient reports a subjective decrease in fetal activity, prompting an assessment such as a non-stress test or biophysical profile.

• Ensure documentation specifies "third trimester" and "other fetus" in a multiple gestation.
• Do not confuse with codes for decreased fetal movements in a singleton pregnancy or for the primary fetus in a multiple gestation.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is the evaluation of the decreased fetal movements.
