O36.813 Decreased fetal movements, third trimester

Name of the Condition

• Decreased fetal movements, third trimester

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 labor, or stillbirth if decreased movements are due to significant fetal compromise.

Lifestyle & Prevention

Encourage regular fetal movement monitoring. Maintain a healthy lifestyle, including proper nutrition and avoiding harmful substances. Attend all prenatal appointments for routine assessments.

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 trimester (third) and specify decreased fetal movements. Ensure clinical notes support the diagnosis and include details on evaluation or management when available.
