Decreased fetal movements, unspecified trimester, fetus 5

This code signifies a maternal diagnosis of reduced fetal activity when the specific trimester is not documented, and the pregnancy involves a fifth fetus in a multiple gestation. It indicates a potential concern for fetal well-being requiring further investigation.

Apply this code when the medical record explicitly states "decreased fetal movements" or "reduced fetal activity" without specifying the trimester, and the patient is pregnant with quintuplets, with this code specifically identifying the fifth fetus. Documentation should clearly indicate the multiple gestation and the affected fetus.

• Ensure documentation specifies "fetus 5" in a multiple gestation; otherwise, a different code for an unspecified fetus or singleton pregnancy would be appropriate.
• Always sequence this code after the primary obstetric code (e.g., O30.1- for quintuplet pregnancy).
• If the trimester is known, select a more specific code from the O36.81- subcategory that includes the trimester.
