Other atelectasis of newborn

This code signifies the incomplete expansion or collapse of lung tissue in a newborn, not otherwise specified as primary or other specific types of neonatal atelectasis. It indicates a general diagnosis of lung collapse occurring shortly after birth, impacting gas exchange and respiratory function.

Use this code when documentation specifies "atelectasis of newborn" without further detail, or when other specific types (e.g., primary, massive) are ruled out. Supporting documentation includes chest X-ray findings, respiratory distress symptoms, and physician notes indicating lung collapse in a neonate.

• Do not use for congenital atelectasis (P28.0) or massive atelectasis of newborn (P28.10).
• Ensure documentation clearly states "newborn" or "neonatal" to differentiate from atelectasis in older infants or adults.
• Consider sequencing this code after a code for the underlying cause if known and documented (e.g., respiratory distress syndrome).
