O36.8133 Decreased fetal movements, third trimester, fetus 3

Name of the Condition

• Decreased fetal movements, third trimester, fetus 3

Summary

Decreased fetal movements in the third trimester refer to a reduction in the normal activity or movements of a fetus, as perceived by the mother. This condition may indicate potential concerns with fetal well-being and requires clinical evaluation to assess fetal health.

Causes

Causes can include placental insufficiency, fetal growth restriction, umbilical cord issues, or maternal health problems such as hypertension or diabetes. Other factors may involve fetal position or maternal perception of movement.

Risk Factors

• Advanced maternal age
• Pre-existing conditions (e.g., hypertension, diabetes)
• Previous pregnancy complications
• Substance use (e.g., smoking, alcohol)
• Multiple gestation

Symptoms

Noticeable reduction in fetal movements compared to prior patterns. Maternal concern about fetal activity levels.

Diagnosis

Diagnosis involves assessing fetal well-being through methods such as ultrasound to evaluate amniotic fluid and fetal movement, non-stress tests to monitor heart rate, and maternal reporting of movement patterns. Clinical evaluation may also include physical exams and history review.

Treatment Options

Close monitoring of fetal activity and maternal health. Addressing underlying maternal conditions (e.g., managing hypertension). Possible hospital admission for intensive monitoring in severe cases.

Prognosis and Follow-Up

Prognosis depends on the underlying cause and timely intervention. Regular follow-up is essential to monitor fetal status and adjust care as needed.

Complications

Potential complications include fetal distress, preterm birth, or stillbirth if decreased movements indicate significant fetal compromise.

Lifestyle & Prevention

Regular prenatal care, monitoring fetal movement patterns, and addressing maternal health conditions can help reduce risk. Avoiding substances that may affect fetal activity is recommended.

When to Seek Professional Help

Seek immediate medical attention if fetal movements decrease significantly or stop, as this may signal a serious issue requiring prompt evaluation.

Tips for Medical Coders

Document the specific trimester (third) and fetus number (3) clearly in the medical record. Ensure clinical documentation supports the diagnosis and any associated maternal or fetal factors. Code O36.8133 is specific to decreased fetal movements in the third trimester for fetus 3 and should be used when these details are documented.
