O36.812 Decreased fetal movements, second trimester

Name of the Condition

• Decreased fetal movements, second trimester

Summary

Decreased fetal movements in the second 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 if concerns persist
• Follow-up imaging or testing as clinically indicated

Prognosis and Follow-Up

Prognosis depends on the underlying cause and timely intervention. Regular follow-up is essential to monitor fetal status and maternal health. Outcomes may improve with early detection and appropriate management of contributing factors.

Complications

• Fetal distress
• Preterm labor
• Intrauterine growth restriction
• Stillbirth (in severe or untreated cases)

Lifestyle & Prevention

• Encourage regular fetal movement monitoring by the mother
• Maintain a healthy lifestyle, including balanced nutrition and avoiding harmful substances
• Attend all prenatal appointments for routine assessments
• Report any changes in fetal movement promptly to healthcare providers

When to Seek Professional Help

Seek immediate medical attention if fetal movements decrease significantly or stop, or if other concerning symptoms (e.g., bleeding, cramping) occur. Prompt evaluation is critical to assess fetal well-being.

Tips for Medical Coders

Document the timing (second trimester) and clinical findings supporting decreased fetal movements. Include details of assessments performed (e.g., non-stress tests, ultrasounds) and any interventions initiated. Ensure the code O36.812 is used when the condition is the focus of maternal care during the second trimester.
