What This Code Means

A condition where a newborn's lungs fail to expand properly at birth due to lack of surfactant or other primary causes.

Coding Tips

• •Primary atelectasis is distinct from secondary atelectasis and should not be confused with respiratory distress syndrome
• •Document whether this is associated with respiratory distress syndrome, as this affects coding accuracy

Clinical Significance

Primary atelectasis of newborn represents failure of alveolar expansion at birth, typically due to surfactant deficiency or other developmental issues. This condition requires immediate respiratory intervention and can lead to significant complications if not promptly recognized and treated, affecting initial adaptation to extrauterine life.

Documentation Requirements

• ✓Evidence of lung collapse or incomplete expansion at birth
• ✓Confirmation of primary nature (not secondary to other causes)
• ✓Gestational age and birth weight
• ✓Chest imaging showing atelectasis
• ✓Clinical signs of respiratory distress
• ✓Apgar scores if available
• ✓Initial respiratory management provided
• ✓Surfactant administration if given
