2025 ICD-10-CM code O36.8125

Decreased fetal movements, second trimester, fetus 5.

This code should only be used on the maternal record, never on the newborn record. Use additional code Z3A.- to identify the specific week of pregnancy. Do not use this code for supervision of normal pregnancy (Z34.-) or labor and delivery complicated by fetal stress (O77.-).

Medical necessity is established by the clinical findings and the physician's judgment regarding the potential risk to the fetus due to decreased movement.Further investigations and monitoring are often medically necessary to assess fetal well-being.

The physician caring for the pregnant woman is responsible for assessing and documenting the decreased fetal movements and determining the appropriate management.

In simple words: This code indicates that the fifth baby in a woman pregnant with multiples is experiencing reduced movement during the second trimester (weeks 14-28 of pregnancy).

This code is used to describe a situation during the second trimester of pregnancy where a decrease in fetal movements is observed in fetus 5.This is a specific code indicating decreased fetal movement in a multiple gestation pregnancy, specifically for the fifth fetus.

Example 1: A woman pregnant with quintuplets presents at 20 weeks gestation with concerns about reduced movement of one of the fetuses, confirmed as fetus 5 on ultrasound. The physician documents decreased fetal movements and orders additional testing., A pregnant woman at 18 weeks, carrying five fetuses, undergoes a routine ultrasound that reveals reduced movement of fetus 5 compared to the other fetuses.This is documented and further monitoring is scheduled., A woman pregnant with quintuplets at 24 weeks is admitted for observation due to decreased fetal movement noted by the mother in one fetus, identified as fetus 5. Continuous fetal monitoring is initiated.

Documentation should include the presence and degree of decreased fetal movement, the method of assessment (e.g., maternal perception, ultrasound), the gestational age, and any associated signs or symptoms. Any interventions or further investigations should also be documented.

** This is a billable code under the Maternity Dx (12-55 years) and Female Dx categories. It is specifically used for cases involving decreased fetal movements in a quintuplet pregnancy during the second trimester.
