Decreased fetal movements, third trimester, fetus 3

This code signifies a reduction in the frequency or strength of fetal movements experienced by the mother during the third trimester of pregnancy, specifically when monitoring the third fetus in a multiple gestation. It indicates a potential concern for fetal well-being requiring further assessment.

Apply this code when documentation explicitly states decreased fetal movements in the third trimester for the third fetus. This typically occurs during routine prenatal visits or when a pregnant patient reports a subjective decrease in fetal activity, prompting further evaluation such as non-stress tests or biophysical profiles.

• Ensure the documentation clearly specifies "third trimester" and identifies the "third fetus" in a multiple gestation.
• Do not use this code if the decreased movements are noted in a different trimester or for a different fetus number.
• Always sequence this code as a secondary diagnosis, with the primary diagnosis reflecting the reason for the encounter (e.g., routine prenatal care, high-risk pregnancy).
