P07.14 Other low birth weight newborn, 1000-1249 grams

Name of the Condition

• Other low birth weight newborn, 1000-1249 grams

Summary

This condition refers to newborns with a birth weight between 1,000 and 1,249 grams (approximately 2.2 to 2.75 pounds). Infants in this weight range are often premature and may have underdeveloped organ systems, requiring specialized medical care to address potential health risks and support growth.

Causes

Low birth weight in this range commonly results from premature birth, where the infant is delivered before completing 37 weeks of gestation. Intrauterine growth restriction (IUGR), maternal health conditions (e.g., hypertension, infections), or complications during pregnancy that affect fetal development may also contribute.

Risk Factors

• Maternal factors such as age (very young or older), poor nutrition, or substance use can increase risk.
• Multiple pregnancies, previous preterm births, and inadequate prenatal care are associated with higher likelihood.
• Chronic maternal conditions (e.g., diabetes, preeclampsia) may impact fetal growth.

Symptoms

• Birth weight between 1,000 and 1,249 grams.
• Underdeveloped physical features (e.g., thin skin, limited subcutaneous fat).
• Difficulty regulating body temperature or feeding.
• Potential respiratory or metabolic instability.

Diagnosis

Diagnosis is confirmed by measuring the newborn’s weight at birth and verifying it falls within the 1,000–1,249 gram range. Gestational age is assessed to determine if prematurity is a contributing factor, and physical exams evaluate organ maturity and overall health.

Treatment Options

Care typically involves specialized neonatal support, including temperature regulation, respiratory assistance, and nutritional support (e.g., parenteral or tube feeding). Monitoring for complications and developmental follow-up is standard.

Prognosis and Follow-Up

Prognosis depends on gestational age, overall health, and presence of complications. Long-term follow-up may be needed to assess growth, developmental milestones, and address potential delays or chronic conditions.

Complications

• Respiratory distress or chronic lung disease.
• Infections (e.g., sepsis, pneumonia).
• Feeding difficulties or growth issues.
• Neurodevelopmental delays or cerebral palsy.
• Vision or hearing impairments.

Lifestyle & Prevention

Prenatal care, including regular check-ups, nutrition, and management of maternal health conditions, can reduce risk. Avoiding substance use and maintaining a healthy lifestyle during pregnancy supports fetal growth.

When to Seek Professional Help

Seek immediate medical attention if the newborn shows signs of distress (e.g., difficulty breathing, poor feeding, lethargy) or if there are concerns about growth or development during follow-up visits.

Tips for Medical Coders

Use this code for newborns with a documented birth weight of 1,000–1,249 grams. Ensure documentation specifies the weight range and supports the diagnosis. Verify gestational age and any associated conditions (e.g., prematurity) to confirm appropriate coding.
