Primary atelectasis

This code represents the initial or congenital collapse of lung tissue, typically occurring in newborns. It signifies a failure of the alveoli to expand properly at birth, leading to reduced gas exchange.

Apply this code when documentation clearly indicates atelectasis as the primary issue in a neonate, often diagnosed shortly after birth. This is typically supported by chest X-ray findings and clinical signs of respiratory distress in a newborn.

• Differentiate from acquired atelectasis, which is coded differently and has various causes.
• Ensure documentation specifies "primary" or "congenital" to support this code.
• Consider sequencing with codes for associated respiratory distress or prematurity, if applicable.
