O60.12X3 Preterm labor second trimester with preterm delivery second trimester, fetus 3

Name of the Condition

• Preterm Labor Second Trimester with Preterm Delivery Second Trimester, Fetus 3

Summary

Preterm labor second trimester with preterm delivery second trimester, fetus 3, refers to the onset of regular uterine contractions and cervical changes between 20 and 27 weeks of gestation, resulting in delivery of a third fetus. This condition requires prompt evaluation to assess maternal and fetal well-being and guide management.

Causes

The exact cause is often unknown but may involve infections, uterine overdistension, placental abnormalities, or hormonal changes. Other potential triggers include stress, trauma, or underlying maternal conditions affecting pregnancy.

Risk Factors

• Previous preterm labor or birth
• Multiple gestation (e.g., twins)
• Uterine or cervical abnormalities
• Chronic conditions (e.g., hypertension, diabetes)
• Substance use (e.g., smoking, alcohol)
• Poor prenatal care

Symptoms

• Regular contractions (e.g., 4+ per 20 minutes)
• Pelvic pressure or cramping
• Vaginal bleeding or discharge
• Low back pain
• Cervical dilation or effacement

Diagnosis

Diagnosis involves assessing uterine activity, cervical changes, and fetal status. Tools may include fetal monitoring, cervical length measurement via ultrasound, and testing for fetal fibronectin in vaginal secretions.

Treatment Options

• Tocolytics to delay labor (e.g., for 48 hours)
• Corticosteroids to enhance fetal lung maturity
• Antibiotics for infections
• Magnesium sulfate for neuroprotection
• Bed rest or activity restriction

Prognosis and Follow-Up

Prognosis depends on gestational age, fetal status, and response to treatment. Close follow-up is essential to monitor maternal and fetal health, manage complications, and plan for delivery or ongoing care.

Complications

• Preterm birth complications (e.g., respiratory distress)
• Neonatal intensive care unit (NICU) admission
• Long-term developmental issues
• Maternal infection or hemorrhage

Lifestyle & Prevention

• Regular prenatal care
• Avoiding tobacco, alcohol, and illicit drugs
• Managing chronic conditions (e.g., diabetes, hypertension)
• Recognizing and reporting early symptoms promptly

When to Seek Professional Help

Seek immediate medical attention for regular contractions, vaginal bleeding, fluid leakage, or pelvic pressure during the second trimester.

Tips for Medical Coders

Document the specific trimester (second), delivery outcome (preterm), and fetus number (3) to support accurate coding. Ensure clinical documentation aligns with the code's specificity, including details on gestational age and fetal count.
