Decreased fetal movements, third trimester, fetus 4

This code signifies a maternal condition where a pregnant patient in her third trimester reports a reduction in the frequency or strength of fetal movements, specifically when the pregnancy involves quadruplets and the concern is related to the fourth fetus. It indicates a potential compromise to fetal well-being requiring further evaluation.

Use this code when documentation clearly indicates a maternal complaint of decreased fetal movement during the third trimester of a quadruplet pregnancy, and the clinical assessment or suspicion points to the fourth fetus as the one exhibiting reduced activity. Supporting documentation would include physician notes detailing the patient's report, gestational age, and the identification of the affected fetus.

• Ensure the documentation specifies "third trimester" and clearly identifies the fourth fetus in a quadruplet pregnancy.
• Do not use this code if the decreased movement is attributed to a different fetus or if the pregnancy is not a quadruplet.
• Always sequence this code as a primary diagnosis when the decreased fetal movement is the reason for the encounter, followed by any associated complications or findings.
