O60.22 Term delivery with preterm labor, second trimester

Name of the Condition

• Term Delivery with Preterm Labor, Second Trimester

Summary

Term delivery with preterm labor, second trimester, is a condition where labor begins between 14 and 27 weeks of gestation but progresses to delivery at or after 37 weeks. This requires evaluation to assess maternal and fetal status and guide management.

Causes

The exact cause of preterm labor is often unknown but may involve factors such as infections, uterine overdistension, or placental abnormalities. Hormonal changes, stress, or trauma can also contribute to its onset.

Risk Factors

• Previous preterm 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

Prognosis and Follow-Up

Prognosis depends on maternal and fetal health. Follow-up includes monitoring for complications and ensuring appropriate postpartum care. Regular prenatal visits are essential to assess recovery and future pregnancy planning.

Complications

• Preterm birth (if labor progresses)
• Fetal growth restriction
• Maternal infection
• Placental abruption

Lifestyle & Prevention

• Attend regular prenatal care
• Manage chronic conditions
• Avoid substance use
• Maintain a healthy diet and activity level

When to Seek Professional Help

Seek care if experiencing regular contractions, vaginal bleeding, or fluid leakage. Prompt evaluation is critical to assess labor status and fetal well-being.

Tips for Medical Coders

Document the trimester of preterm labor onset and confirm delivery timing. Ensure clinical notes support the second trimester onset and term delivery to justify code assignment.
