Unspecified atelectasis of newborn

This code signifies a collapse of lung tissue in a newborn, where the specific type or cause of the atelectasis is not documented. It indicates that a portion of the neonatal lung is uninflated or has lost volume, impairing gas exchange.

This code is appropriate when documentation confirms atelectasis in a newborn but lacks further specificity regarding its etiology (e.g., primary, secondary, obstructive, compressive). It is used when the physician's diagnosis explicitly states "atelectasis of newborn, unspecified" or similar terminology without additional detail.

• Avoid using this code if the documentation provides a more specific type of neonatal atelectasis (e.g., primary, secondary).
• Always review the entire medical record for any clues that might lead to a more precise diagnosis.
• Consider querying the provider if the documentation is ambiguous and a more specific code could be supported.
