Pneumothorax originating in the perinatal period

This code identifies the presence of air in the pleural space of a newborn, occurring around the time of birth. This condition results in lung collapse and respiratory distress, specifically due to events or conditions present during the perinatal period.

Apply this code when documentation clearly indicates a pneumothorax diagnosed in a neonate, with the onset attributed to factors or events surrounding the birth process. Supporting documentation would include physician notes detailing respiratory distress at or shortly after birth, chest X-ray findings confirming pneumothorax, and an absence of other underlying causes.

• Ensure the documentation specifies the perinatal origin; otherwise, consider other pneumothorax codes.
• Do not use for pneumothorax acquired later in infancy or childhood; this code is strictly for the perinatal period.
• Sequence as a principal diagnosis if it is the primary reason for admission or encounter, or as a secondary diagnosis if it complicates another perinatal condition.
