O60.12 Preterm labor second trimester with preterm delivery second trimester

Name of the Condition

• Preterm Labor Second Trimester with Preterm Delivery Second Trimester

Summary

Preterm labor second trimester with preterm delivery second trimester is the onset of regular uterine contractions and cervical changes between 20 and 27 weeks of gestation, resulting in delivery. 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

Prognosis and Follow-Up

Prognosis depends on gestational age at delivery and fetal maturity. Close follow-up is essential to monitor maternal recovery and infant development. Long-term outcomes may include increased risks of developmental delays or chronic health issues for the infant.

Complications

• Respiratory distress syndrome in the infant
• Intraventricular hemorrhage
• Necrotizing enterocolitis
• Maternal infection or hemorrhage
• Preterm premature rupture of membranes

Lifestyle & Prevention

• Regular prenatal care to monitor high-risk conditions
• 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. Early intervention can improve outcomes for both mother and fetus.

Tips for Medical Coders

Document the trimester (second trimester) and confirm preterm delivery occurred within the same trimester. Ensure clinical documentation supports the timing of labor onset and delivery to justify the code.
