P07.03 Extremely low birth weight newborn, 750-999 grams

Name of the Condition

• Extremely low birth weight newborn, 750-999 grams
• ICD-10-CM Code: P07.03

Summary

Extremely low birth weight newborns weighing 750-999 grams at birth are infants with birth weights significantly below the average range, typically resulting from premature delivery. These newborns require intensive medical care due to underdeveloped organ systems and increased vulnerability to health complications.

Causes

Premature birth is the primary cause, often occurring before 28 weeks of gestation. Other factors may include intrauterine growth restriction, maternal health conditions (e.g., preeclampsia), or complications during pregnancy that affect fetal development.

Risk Factors

Maternal age (very young or older), poor nutrition, substance use, chronic health conditions, multiple pregnancies, and inadequate prenatal care can increase the risk of extremely low birth weight.

Symptoms

Newborns may exhibit low birth weight relative to gestational age, underdeveloped physical features, difficulty regulating body temperature, and respiratory or feeding difficulties.

Diagnosis

Diagnosis is confirmed by measuring the newborn's birth weight immediately after delivery. Prenatal assessments, such as ultrasound, may also help monitor fetal growth and identify risk factors.

Treatment Options

Immediate postnatal care in a neonatal intensive care unit (NICU) is standard, including respiratory support, temperature regulation, and specialized feeding. Long-term management may involve developmental monitoring and interventions.

Prognosis and Follow-Up

Prognosis depends on gestational age, birth weight, and associated complications. Follow-up care includes regular developmental assessments, monitoring for long-term health issues, and support for growth and neurodevelopment.

Complications

Common complications include respiratory distress syndrome, infections, intraventricular hemorrhage, and long-term developmental delays. Mortality risk is higher compared to infants with higher birth weights.

Lifestyle & Prevention

Prenatal care, avoiding substance use, maintaining a healthy diet, and managing maternal health conditions can help reduce the risk of extremely low birth weight. Early prenatal monitoring is key to identifying and addressing potential issues.

When to Seek Professional Help

Seek immediate medical attention if a newborn shows signs of distress, such as difficulty breathing, poor feeding, or abnormal temperature regulation. Prenatal care providers should be consulted for any concerns during pregnancy.

Tips for Medical Coders

Document the exact birth weight (750-999 grams) and confirm gestational age to support accurate coding. Ensure documentation aligns with clinical findings and includes details on any associated complications or interventions.
