In simple words: This code is used for newborns who experience breathing problems related to air trapped in the lung tissue, different from typical newborn breathing issues.

This code encompasses other respiratory conditions related to interstitial emphysema that originate during the perinatal period (from before birth through the first 28 days after birth).Interstitial emphysema refers to air trapping within the lung tissue outside of the normal air sacs.

Example 1: A newborn infant develops difficulty breathing shortly after birth and imaging reveals air in the tissues of the lungs outside the normal air sacs. After ruling out other causes like pneumothorax, P25.8 is used., A premature baby on a ventilator develops complications with air leaking into the lung tissue. Other specific diagnoses are ruled out, making P25.8 appropriate., A newborn experiencing respiratory distress exhibits unusual air pockets in the lung tissue. This fits the description of P25.8 as a condition related to interstitial emphysema.

Thorough documentation should include details of the infant's respiratory status, imaging results confirming abnormal air in lung tissue, and exclusion of other classified conditions like pneumothorax, pneumomediastinum or pneumopericardium. Specific details on the infant’s gestational age, delivery complications, and ventilator settings (if applicable) are crucial.
